A lot of PC builds online (including manufacturer photos & NR200P builds) incorrectly mount AIO liquid coolers, leading to pump noise/whine and early cooler failure.

We've wanted to do this video idea for a long time now, but finally got around to it after seeing an increase in manufacturers incorrectly picturing liquid coolers installed in their cases. Bitfenix and Cooler Master have both shown installation procedures that can actually kill the cooler, while pretty much everyone else has shown some form of sub-optimal installation that will minimally hurt the acoustic performance of coolers. In instances of mini-ITX cases like the Cooler Master NR200P, we've noticed a lot of build photos on forums online (and in TRvid media, but we don't blame the YTers or builders for overlooking this) installing coolers bottom-mounted. This, we think, isn't an issue with the reviewers or the PC building enthusiasts, but with the educational materials provided with the cases. The fact that there is an explicitly mentioned bottom-mount for radiators in a case where it's very likely to be used is a problem, and any case with such a mount should include warnings against installing closed-loop liquid coolers with block-mounted pumps in these positions. Installing a custom loop bypasses this issue, since the pump is almost never going to be in the block, and therefore should never be at the top of the loop (it's more likely to be in the middle of the loop). But AIO CPU coolers should not ever be bottom-mounted with the pump at the top of the loop. Manufacturer websites (shown in this video) also commonly show front-mounted radiators with tubes at the top, which will become noisy as permeation increases, and sometimes can be noisy immediately. This video is a PSA to try and help reduce pump whine, pump noise, and prevent liquid coolers from dying early or overheating.

The motors aren't that powerful, you'd need to go to industrial applications for that. Cavitation is when water vaporizes on the surface of an impeller, which isn't happening in these hobbyist-level motors. With cavitation, air isn't in the voids formed but water vapor is. With CLCs/AIOs, it's just air bubbles getting pulled through the loop (not cavitation).

Just bought the Corsair h170i elite capellix 420mm AIO. I will be mounting the radiator at the top of the case and the pump below it. I’m going to be cooling a 7950x that has a target temp of 95C. I know with a larger radiator it takes longer to get to 95C. Will I have to worry about too high radiator temps with the cpu running at its max 95C? Thank you for this video.

Greymane_Gaming 4 aylar önce

@jazzochannel yes on the ambient air temp... I live in a location with cold winters and hot and humid summers... the major difference in my PC cooling is my room's temp. As a welder, I am used to being hot and a 90f room is okay with me... my old PC however used to overheat constantly with air or liquid. Kicking my room's ac unit on stopped it. That being said... I have just bought a new h100i lc specifically because I like the lower profile and had the extra few bucks... but if the cpu had come with an air cooler, I'd have used that instead and saved the cash because the difference between the 2 for me was only 2-3c at ambient/uncontrolled room temps... and too hot is too hot when it's tripping the thermal protection of you system.

jazzochannel 5 aylar önce

@Johnny Flech yes. that's who i'm talking to. AIOs are a massive gimmick with marginal benefits over air cooling. custom pc-liquid-equipment is an overpriced niche marked. also not worth the effort or the cost imo. it's all very overpriced, very "elitist" equipment that gives the user 5-10 more FPS in a game or completes some task in 275 minutes instead of 295 minutes, lets say. The performance you gain from using these products vs the price and time to set up is for the most part not worth the effort - but that's a subjective judgement and it depends on how you value your time. don't even try to play the "enthusiast" card with me. "PC temps do not exceed 90°C ever" Sounds like you haven't lived in a area where ambient temp is 35-45 C and you're trying to compile or render some project that takes more than 60 minutes. Note this: liquid and air cooling is equally useless if the ambient temps are high. they are equally dependent on ambient temps.

Unfortunately, front-mounted, tubes-up is often the only way a particular liquid cooler will fit it a particular case, either because there aren't appropriate mounts anywhere else and the tubes are too short for tubes-down, or because there's an issue with clearance related to the motherboard or the RAM that prevents mounting it in the top of the case.

Asus Tuff Gaming mATX case/motherboard/280mm AIO also suffers this same issue. Cannot top mount, RAM in the way, and front mount can only go hoses up because the (riveted in) PSU shroud is in the way. Woe is me. I keep getting water noises a few times a day, like a trickling noise from it shuffling some air around, so probably need to replace the chassis before I have to replace both the chassis and the AIO.

Thank you for this extremely informative video before I install my liquid cooler. How do we feel about a 120mm square radiator being mounted with tubes on the side rather than the bottom? Based on this science, it seems that it would function at least just as well as tube on the bottom since both tubes would still be totally submerged where they meet the radiator.

Awesome video. Mad props to you and your channel. I remember when I first installed an AIO on my 2500K and was searching for the proper way to mount it... (almost 10 years ago I think) Came across some pretty stupid suggestions that made me doubt my ...education... (physics was probably my favorite subject in school) I was going through sites and some videos and was constantly thinking "that can't be right". Fast forward to recent years, I've been low key looking at a replacement case for a "secondary" PC I have and bad radiator placement is very common on many of products pictured.

Mahe N 7 aylar önce

Thank you for enlighten us, and huge thanks for making this video. You are totally awesome. I almost thought I need a new cooler but following your instructions saved my pc. flipping and putting pump pipes lower and keeping the radiator its position upper then pump and saved lot of noise. Surprising is that, last 12 years I had Radiator pipes up never got any issues but when started cleaning my pc and I added new thermal past and plugged it back same as before nothing changed, suddenly its started making very loud bubble noise and my pc temperatures where very high up to 80C in min and also got shut down by its self, I wasn't sure what's happening. I thought Its time for new cooler but luckily I watched your video followed your instructions solved my problem straight away, I still little spectacle about it, slight small noise hardly I can hear and my CPU temp is back to about 32-38 that's awesome. (I kept the radiator pipes down and whole radiator higher then the cpu pump).

I've been looking everywhere for the answers that literally only this video provides. I'm building with an AIO for the first time in two days. I did so much research and was convinced until this moment that tubes up vs tubes down didn't matter for front mounted radiators. I'm so relieved to have GN finally provide a definitive answer on this, yet pissed that AIO has been around for God knows how long and only now is there a correct answer floating around as to how you're supposed to mount your shit.

It is a marketing trick. Manufacturers want you to buy their coolers more often by improperly mounting it and shortening the longevity of coolers. The faster it degrades, the sooner you have to buy another one pushing their sales up

The problem I find is the tubing on these AIO coolers is nearly always too short to mount them properly with the tubing at the bottom of the radiator as described in this video. If the manufacturers would just make the tubing a bit longer this might actually be a possibility, but pretty much every build I've done that isn't top mounted has to be upside down due to the pitifully short length of tubing provided on these units.

I’m surprised I haven’t seen any manufacturers with their tubes half way up the rad. Where the fluid enters from half height, goes to the top of the rad, all the way down, and half way back up before returning back to the tubes. This would allow the rad to be installed in any direction plus likely provide GPU clearance.

From an engineering standpoint, you couldn't do this without reducing the total surface area, and thus your cooling performance. You'd also PROBABLY have to deal with air getting trapped in the middle near the outlet. Air does indeed want to go up, but it's happy with local minima, especially in low pressure systems like AIOs. Kinda like how a boat flipped upside down will keep a pocket of air a few meters underwater.

@Weeblicker it’s clear you’re not picturing what I’m trying to portray because that’s exactly how water works. Imagine 1/2 up on one side 1 full length down on the other then the other half way back up the original side…

David jeffers 2 aylar önce

@Weeblicker maybe not but it is how flow works. Imagine the front half split and the back half full. Now connect your intake to the front mid going to front top. This passes to rear top, full length to rear bottom. Passes back to front bottom. And front bottom to front mid just below intake, the now cool water exhausts to pump line. You still have 240m of cooling but from intake to exhaust you are roughly mid-aio the whole time.

This is exactly why a good case design makes this trivial. The Lian Li 011 Air / Air mini has a mounting area on the backside of the case, so if you mount tubes-down there, you can easily reach a hybrid / liquid cooled GPU at the bottom portion of your motherboard. Now for the CLI cooler, the case has a radiator spot at the top of the case to make a proper install easy.

@Skelath All the other noises you are referencing have water being added to a system rather than a closed system. In a large contained system where droplets can form and fall, your other theories might stand. Inside of heat pipes there is no room for the liquid to form droplets and fall onto an open surface. It will basically condensed on the sides and slide back down. Otherwise there is very little movement in the system.

@ytilanigiroon Also to further elaborate thermal heat pipes use capillary action aka it's the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. During operation of a heat pipe, heat supplied to the evaporator vaporizes the working fluid, which travels down to the condenser. The vapor condenses in the condenser, and the liquid is drawn back to the evaporator by the wick, using capillary forces.

Dean Zeelie 9 aylar önce

Great video, but how does it effect the AIO units where the pump is situated in the middle of the radiator? Because the pump will always be drowning in the coolant. Does it still matter whether the pipes is on top or bottom? I understand it's even the same as a car engines where you want the engine(heat source) drowned in coolant and slightly below the rad.

Your video was excellent and very informative. I was pleased to see that my installation was done correctly. (Small pat on my back.) I have never understood why these AIOs use non-transparent tubing. I would like to see my coolant moving thru the system. That way, I could see that the pump was working correctly and any air bubbles in the loop. Also, why do the manufacturers not include a separate reservoir in the loop? That would allow me to see two things: Any air bubbles are being expelled and knowing that the loop is completely filled. Maybe you could produce a video showing how to add transparent tubing and a reservoir to the AIO. I'm thanking EK here, but my PC came with AIO installed. Before you build that gaming PC, determine what you will place into the case to ensure that they will actually fit, width, length, and height.

Great video, I am in to mechanics and understand vehicle radiators, and how the air travelles around the system always reaches the highest point. I have a corsair 4000d corsair suggest the 360mm radiator, to me suggests its an air free 100% liquid system, I was considering the 280mm because it fits at the top making cooling better because heat always rises. This video has helped me make up my mind 100% understanding they are not an air free sealed units, so the 360mm configuration is definitely not an ideal choice, like shown on the corsair site.

This is easily fixed by redesigning how the tube interfaces with the radiator. Rather than going straight into the radiator, there should be a small pipe, with one end always submerged (imagine a drinking straw). That way, any air that gets trapped in the top of the radiator will not interfere with the suction back to the pump.

It'll always get more air in it though, over time. I'd just fit a hygroscopic automatic bleed valve.

Yep. You must use the top of the radiator (I/O pipes below) as an air trap. I installed a vertical radiator, so the air trap was above the pump n block by about 3.5cm to ensure it gets no air gets into it too. It worked flawlessly. Very quiet, very efficient, faster on loads, and temps were the absolute best. Because if the pump is too low, if there is any air is in the top of the radiator, the pump has to push water up OUT of the IN radiator to flow into the OUT radiator. To have gravity place an immediate resistance onto the pump is not optimal. I feel, even if you have a top mounted radiator, the pump too low will have to push water upwards into the IN radiator and rise up before it will come back out of the OUT radiator. Keeping the pump just below the air trap with as little of the res water above, in a 100ml system, will reduce static pressure on the pump by at least 90 grams even when the PC is off. But the pump and IO pipes MUST be below the air trap and the IN line to the pump n block on top above the pump n block OUT line as in the video^ .

seems to me that once you have the part that attaches to the cpu you could just attach it to an aquarium pump outside the case. and since your using a better pump where orientation doesnt matter simply place the radiator inside the mini fridge sitting next to the computer desk or strap it to the side of a box fan, maybe drop the radiator all together and just cycle the flow from inside an actual fish aquarium. either way you save hundreds, regain space in the case and gain superior cooling even if you do little more than run the tubing to a 3-5 gallon water jug. or go all out.

Just bought my first water AIO and after reading around was starting to have doubts about installing it because of so many people complainign about gurgling and pump whine etc. I had all but decided to return it in favor of the "big ass noctua" that's proving so popular (and MUCH cheaper), however it seems it could well be they were all just mounted wrong.

The noctua n15 is comparable to many 240 or 280 rads in terms of cooling, thermals and sound, based on GN charts from most recent best of video. It can’t compare to the 360 or 420 rads, but if you don’t need that much cooling, then that kind of air cooling is totally viable. GN tested the n15 with a i9 12th gen, so it was up to cooling that stock. I like the safety of air cooling - I personally prefer parts that don’t have even the potential to fail in a way that will damage other parts, but that might be my engineering background. I am thrilled aio are so so much more reliable than when they first came on the market tho.

You mentioned it might not be the coolest as you have to exhaust. You can easily put the radiator fan closest to your intake fans as intake too. It is mostly pulling in cool air with the other case fans, while the fan furthest is set to exhaust (this is for my 240mm aio and running cinebench stress tests I didn't hit more than 68c)

Patriot 03 2 aylar önce

I think it's more important to just have good airflow in your care either way, in my case I prefer to have my CPU AIOs as exhaust at the top of the case (I have to imagine the rising heat helps, steve wrote it off but I think heat rising is a potent force that I'd prefer my fans not have to needlessly combat) with large intake fans in the front of my case, the back case fan is also an exhaust. So I've got cool air entering the case thanks to large powerful fans and that air flows past the GPU and out of the exhaust, this deliberate flow helps cool all the components in the case including the drives. I'd be a bit concerned about having a top mounted exhaust and then using the nearby case fan as an intake, I wouldn't want to impede the airflow going over the GPU in anyway because it also needs access to cool air/airflow. In the end of the day what matters for the inside components is total airflow measured by volume, the more air that runs past the components per unit of time the better so there's no need for a convoluted setup just sensibly choose how you want the air to flow and utilize the big front case fans which can deliver the majority of that flow. Preferably maintain slight positive pressure in the case to help avoid dust.

Steve, thank you for this explanation on the proper mounting for AIO coolers. It makes perfect sense. In My NZXT case, I mounted my lian li gallihad 3 fan radiator on top. It works very well and never hear it. The other thing about my nzxt case is that it has vents at the top of the case too so the hot air will easily escape. My case has three 120 mm fans in the front of the case pulling fresh air into the case. At idle the Cpu is at around 20 deg Celsius. Even under several pcmark benches, the cpu never got above 38 degrees Celsius.

Wouldn't curving the tubes so that they are lower than the top of the radiator technically trap the air in the radiator? If air moves to the top, wouldn't it not be a stretch to assume that the air wouldn't go down the tubes and then up again? Particularly if the pump isn't really strong enough to move air? Asking because this is the only way I can install my radiator...

I'm an industrial pump mechanic, I can tell you right now when you seat the AIO improperly you're going to get air in the impeller, that causes cavitation(micro explosions of air), which will absolutely ruin any kind of centrifugal pump. Great video.

drb0mb Yıl önce

guys, a pump mechanic doesn't know about physics, and this isn't cavitation. the impeller would have to be spinning so fast that it creates a low pressure area strong enough to prompt evaporation in the coolant to cause cavitation. those evaporation pockets would then collapse like a rubber band being pulled back and snapped in a no-fucking-around effort to return to stable pressure. what's happening here is more like swishing mouthwash around, which doesn't displace molars over time.

Fabio Lessa Yıl önce

No way on this earth this scenario would cause cavitation. Cavitation IS NOT the mere presence of air/bubbles in the flow. Cavitation is what happens when due to low-pressure sessions (usually vortexes) the liquid goes to a vapor state (liquid's vapor pressure equilibrium) and right after the low-pressure session ends, the vapor transition back to liquid. That usually happens extremely fast which in turn generates pressure/shock waves. These shock waves are what, in turn, damages the structure. These little cute pumps are FAR from being able to generate these pressure shifts. That being said, the bubbles do cause all the harm described in the video. However, it's not due to cavitation, but rather due to all the reasons Steve correctly pointed out. -- Mechanical-aeronautics engineer/turbine engineer here.

Some coolers can have a glycerine build up issue in the head block too over time. Last dead cooler i replaced for someone i pulled open to look at, and the heatblock was blocked solid by hardened glycerine. Why they put it in there to begin with, my guess is as a lubricant.

Okay, so I watched the whole cooler video... Super-informative but the one thing I didn't hear (or don't recall hearing) was a definitive 'best' orientation. Simple question, top mount versus front mount (assuming tubes elevations are right) - is one better than the other? I'll toss in a request for a video too... you do a lot of case reviews, which are great. But I don't ever recall seeing one that focuses specifically on 'best cases' for water cool solutions. Having a water cooler changes so much... fan selection, noise levels... would be great to see best cases for AIO watercool.

I just bought and installed my very first AIO at the weekend (it's a corsair capellix elite) I put the Radiator at the top with the fans as an exhaust. I know a lot of people say you should do the fans as an intake, but honestly I think this is better for me, as I heard it can help with cooling the GPU more. My CPU isn't that powerful tbh (an 11th gen i5) Also if I wanted it to be an intake I should have gotten the bigger Rad with the 3 fans and put it on the front of my case. My case is a Corsair 680x though, so has good airflow.

Dowlphwin 10 aylar önce

I always cringed at the idea of running radiator fans outside-in. Radiators are meant to dissipate a lot of heat, and blowing all that into the case seems stupid. Although it seems even newer graphics cards tend to suck air in, dunno. I guess the other components inside are less heat-critical and you can just blow air out somewhere else, but that would typically be the front, which can be problematic. And it could also be bad if you combined liquid and air cooling systems.

I had a disaster last night with my aio, it's an uphere branded single fan aio rear mounted tubes down on a 3600, I don't remember buying it but I would imagine it being reasonably well reviewed/price was what lead me to it. I noticed that my idle temp has been getting higher recently and when I start ANY game fans immediately peg to 100% (sometimes even when it's idling and windows starts a background process it Ill stay at 100% for a little while...in my experience the thermal grizzly I used has been good for around 5 years so I was sceptical it was a tim issue but I reapplied it anyway. After reapplying in bios the fans pegged at 100% and the heat is climbing past 80 and despite doing the air bubble dance the pump (which was previously silent) is now screaming. After opening the loop by removing the cpu plate I found a heap of brown residue (no idea what it is) in the corner of the intake channel and the fins are covered in this slimy residue, after some cleaning with acetone first then a rinse with distilled water and refilling loop pump first (and more bubble dancing) it runs about as well as it did from new...this aio is 9 months old... Tl;Dr Despite what the manufacturer says these aio's can be user maintained and if you suspect degraded performance over time due to insufficient cooling I would advise getting some distilled water take the cold plate off inspect for residue and clean it out (if there is any) and by pulsing the pump and adding water you can refill the loop just remember that you will be adding an air bubble when you put the plate back on so you need to get that bubble back into the radiator...might save you buying a whole new aio

It's not that it's a bad idea, very often mounting it tubes bottom will make it hard or impossible to mount longer gpus. As long as the pump is below the highest point of the loop it should be ok. The worst thing that can happen is some bubbling noise in a radiator. I am currently using be quiet! silent loop 2 mounted like that but it has a port for refilling and it comes with a bottle of coolant so if it ever starts to be noisy I will just refill it. It is suboptimal but there won't be any damage.
