Hey, as a 'main stream' audience member I just wanted to say this: Thank you for this explination. I am building my very first PC with a standard AIO watercooler and the first video was clear enough. It made me check my stuff and I actually already mounted the cooler the correct way, but now I know why it's correct. The AIO manual doesn't say anything about it (Corsair H100i). Anyway I just wanted to mention that mainstream audience is layered into 'new enthousiasts' and others :) I suppose I belong to the 'new enthousiast' group and that is entirely thanks to KZbinrs like yourself and people like Jay and Linus.

Does this apply to open loops. Look dude; I suck at math, okay. Be thankful you're good at it. Not everyone can do that! Basically, what I got out 9f this video is, pump at bottom, and do not put a radiator at the bottom. And it is better to push water uphill, rather than downhill, because air tends to go to the highest point. Lol, if I am annoying you, please don't answer.

It's pretty much why a cars engine cooling system it set up like it is. The radiator is the highest point and the pump (and the coolant passages in the engine) sit lower than the highest point of the radiator (yes the radiator in a car is set up slightly different as the radiator inlet is at the top, and the radiator outlet is at the bottom). It's pretty much to avoid air being trapped in the engine. I understood your video pretty clearly.

I had a NZXT X62 Kraken front mounted in a NZXT H510i, so you could maybe call this a joined up solution where they have been designed to fit together. I had it tubes up and it all fitted very nicely top and bottom of the radiator (...and it matched the NZXT photos...) I flipped it round so the tubes were at the bottom. It fits but not as nicely. You have to use all of the available tolerance on the radiator bracket to get it to fit and even then the tubes look uncomfortably tight to the bottom of the case. The 'mainstream audience' would i think draw the conclusion from all of this that the AIO has been designed to be installed front mounted, tubes up and that tubes down is wrong. (1 day in and the clicking noise the pump makes has not gone...)

@@ramshead7379 I've had my 360mm aio front mounted with tubes at the top (but pump/block is at a slightly lower level) for a few years now (think this unit has a gen3 or gen4 pump), the pump speed is low enough that it doesn't pull air through from the radiator and make noise unless the system is really hot where the fans are going balls out and a slight occasional air bubble noise is of no concern.

I just wanted to say thanks for these vids. I've tearing down and building for over 20 years, and running AIO in every build for almost a decade now, and only earlier today while watching the first of these did I even consider running I/O at the bottom of the rad. Inspired me to re-mount my ML240 inside my NZXT510 and got a couple degrees back from having to run fans front blowing through, rather than fans back drawing. I had never realized just how many of the promo images (and indeed reference builds in image searches) have pipes up that were implicitly guiding my mounting orientation. Even the 510 itself has a cutaway in the rad mounting plate for pipes-up to face back through the plate, and all of NZXT's material shows pipes up. Also, if anyone finds this comment and is curious, a CM ML240 will orient pipes-down in this case while working around an Aurus 2080 in the top slot, but it's millimetrically close, and requires the radiator to be mounted in the highest possible position on the inside of the mounting plate. If I could do it all over again, I'd change cases to something that had space for the rad up top instead.

22:13 - As a physicist/engineer, I approve this XD This channel is amazing! Keep the good work! I remember seeing a comparison between front and top-mounted rads*. I think it can really depend on the ventilation of the case**, as there are several factors that come into play here. Might be interesting to see you doing a comparison of your own between mounting positions***. Anyway, as you said, this is not nearly enough as important as the acoustic/performance issue caused by mounting improperly, so if you can't mount it properly at the front just mount it at the top. * Assuming top means as exhaust ** Won't matter as much in a well-ventilated case (hypothesis) ***** Will also be more informative if replicated between different cases. (sry had to do this)

[@alexatkin]

No warning that results may vary between manufacturers, designs, or slight variation if your 12V line is slightly lower/higher? ;)

[@RutgersSieve]

Heat rises is absolutely a factor though. If CFMs matter, contending with natural air movement tendencies matters by default. Hot air will more naturally exhaust at the top, so if the radiator is slowing down the air movement at the top (and it does) then the case will trap more heat. It depends on how much intensity your system is driven to overall of course, but if you're pushing high frame rates at 4K and maxing out your CPU and graphics card, you're probably not going to want them to throttle. Nowadays, CPUs will react not just to high temps, but perceived head room. Small clock differences can matter a lot, as Jay's review of the Ryzen 3000 XT series showed and as Intel benchmarks show.

[@pushyrummble8625]

You don't even need to study for anything to understand this tbh, hot air goes up and if it's in a closed system it will try to go to the highest thing. So make sure it stays trapped instead of it always being moved around within the system.

[@MasEffect671]

Steve, I love your content and your willingness to go to lengths to help people understand a topic. I watched the first video and basically you said front mounted rads with the barbs positioned at the top is a sub-optimal position and changing it to either front mounted barbs down or a top mounted orientation solves an acoustics issue whereas changing from a bottom mounted rad solves an issue related to longevity of the pump performance. Basically, because all AIOs are not 100% filled with liquid, it is advised to orientate the rad so both the pump and the barbs don't inherit the pocket of air within the loop. To achieve this, the rad would either be front mounted with the barbs down or top mounted. This would ensure that the air would rise to a non-malignant area of the AIO liquid loop.

Thank you for the awseome explinations GN. I am at 11:30.

If the tubes are up, being that the air is also up, that means that the pump will get that air in (it makes perfect sense after all, because the tubes are after all, the phisical means to get fluid to the pump, so like a strow in a cocktail: if what is at the other end of the strow is liquid, you will get liquid, but if what is at the other end of the strow is ice cubes and... air, that is what you will "drink").

People using our stuff would ask questions and I could tell them very detailed answers. In one case, I answered a question and someone said "are you sure that's the way it works?" and I replied "yeah, I wrote that bit myself" or the equivalent. I could also tell them stuff like "yeah, it doesn't quite work that way." or "don't do it that way, this other way is faster". They seemed to really like that. Marketing found out and weren't happy. My "marketing" trips became fewer.

No,HERE'S the REAL TL:DR: MARKETING people don't "talk" to the PUBLIC. But an eager 14 year old's "know-it-alls" just love to represent as "experts" and pass their "knowledge" to other 14 year old's with less knowledge....

Good video. Recently moved my build from a Corsair 760t to a Lancool ii performance. When moving the Corsair 280mm AI0 (4 yrs old) from the top of the 760t to the front of the Lancool ii with the tubes up because the lines were not long enough otherwise, my system overtemped. Trouble shooting showed the AIO failed. Replaced with new AIO with no overheating. Tossed the old AIO into the trash. It probably would have worked in one of my other systems with the tubes down but it is now in a landfill somewhere. I know better and should not have trashed it. Thanks for the video but for me the reminder was too little too late. Thanks and keep telling and reminding us about issues like these.

Steve, thank you for this. Did my first build with a 3 fan radiator and mounted it in the front of the case.

Both of these were worth the journey, and I really appreciated having the visual that shows me the water flow inside the AIO.

[@zexLlama]

It's actually extremely easy to solve the problem for front mounted radiators with tubes up. All the manufacturers have to do is have the IN and OUT tubes just slightly more towards the middle of the radiator. This will prevent air from getting back into the loops and could also solve the problem for tubes down since at the moment the long graphics cards (RTX 3080s and 2080s - tubes are too short to cross over them) make it impossible to have that orientation in more traditional cases (unless you use a case like the Lian li o11).

[@wheresbrent]

This is what I was thinking as well.

[@flakeyman2301]

This is essentially how a lot of hot water storage cylinders work, in the UK at least. The outlet is on the top of the tank with a dip tube dropping down inside, this means the tank cannot be vented of its top section of air, creating an "expansion gap". This eliminates the need for separate expansion requirements if sized correctly for the system and should never drag air once it has finished initially filling/venting.

High five noctua gang. I for one do not regret my purchase.

[@ravenshrike]

Less than 10 degrees C(between the x72 and the Deepcool and Noctua) when noise normalized means that unless you're hotboxing the CPU those better thermals are largely irrelevant. But I suppose I should amend my initial statement to cover all the bases. Aesthetics, form factor issues, very poor case airflow, or bragging rights. In terms of everyday performance the difference is a negligible. While Ryzen technically improves it's clock speed at lower temperatures, for a actual significant difference you need to drop it farther than an AIO can.

[@TheOneTonHammer]

@@GamersNexus Are we talking steady state, because my PC runs for days at a time, doing workstation stuff. Steady state is irrelevant. The Noctua does a great job and cools the VRM's to boot.

[@thatboringone7851]

13:32 (Also 24:00) I was one of those probably incredibly annoying people asking for clarification on this - that visual _really_ helps, completely cleared my confusion about the wrong and right way to front mount an AIO. AIOs and the terminology for their parts are new to me (I was dead set on only using fans until I heard about the Liquid Freezer II that sold out before I could buy one), so it was kind of tricky to understand from the description itself.

[@kaichuuuuuu]

Thanks for the clarification video! To begin, as a noob in liquid coolers, I was so confused with what "tubes at the top/bottom" means, because I did not know whether that meant off the pump or off the radiator, but the 25:50 topic covers that. I personally had a bit of confusion with the "examples of correct/incorrect installation" part in the previous video just because the voice over and the b-rolls weren't explaining the same thing all the time. It also initially almost sounded to me like tubes on the top would really damage the cooler to me. It makes a lot of sense now though after doing a ton more research and watching this video. I had an issue with air just being completely trapped in the system causing my cpu to crash from overheating and I realized that was because I had the pump in the middle of the loop but the tubes at the top. Flipping it upside down for a while and bleeding it fixed everything. My new build's gonna have a big chungus GPU that would be impossible for the tubes to go to the bottom of the rad without having to go in front of the GPU but it's reassuring knowing that my pc won't explode from the tubes being at the top.

[@pieking4]

would it make sense for AIO manufacturers to start offering coolers with longer tubing to fit the needs of different use cases? to me it seems very odd that there are situations where if one wants to install a 360mm AIO front-mounted that there's a chance the tubes won't be long enough to install the cooler in the optimal orientation. I personally use a Lian-Li Lancool Mesh case which allows the use of a front-mounted 360mm AIO, but only up to a 280mm AIO at the top. My GPU is a Sapphire Nitro+ 5700xt which is an exceptionally long card. That puts me in a position where I would likely have to sacrifice the performance of the 360mm AIO as the tubing likely won't be long enough to make its way from the bottom of the radiator, around the GPU, and up to the CPU socket. I'm pretty much playing the devil's advocate here, as for my use case a 280mm AIO would be more than sufficient to cool my CPU efficiently, BUT for those who use a much more power-hungry chip, why are they put in a position where in some way, shape, or form, they need to sacrifice cooling potential or commit to a much more complicated and expensive solution in order for everything to operate in its optimal configuration?

[@LiquidFoxDesigns]

I would disagree with this because you are now just creating two high spots for air to build, both pump and rad. It makes more sense to have the tubing always traveling uphill from the pump so water settles in the pump and any trapped air can travel away from the pump while not circulating.

[@akiraic]

@@LiquidFoxDesigns that can easily be avoided by NOT MOUNTING the radiator. Mount the pump, put the rad in the correct position outside the case. Let it run for a couple minutes/hours, shake a little bit. After that, you can be sure that there is no bubbles in the pump. Now you can mount the rad in the front panel, slowly and making sure you don't turn it so the bubbles are kept at the rad. At least that's how I always did.

[@antoine6338]

I'm in the same case I have a Lancool II Mesh and I don't know if i should take a 240 AIO to put at the top of my case, or a 360 and take risks to put it with the hoses/tubes at the top and not at the bottom because tubes are too short...
