Let's Talk About AIO Orientation... Again

by this point you've probably seen our original ad for thermal grizzlies carbonate pads they're clean peace of mind replacements for traditional thermal paste and best of all you'll never have to replace them but did you also know that you can buy carbonate pads in different sizes for various processors they even make a giant 51x68 millimeter pad for thread ripper i highly recommend carbonate pads and you can learn more by clicking the link below all right so this video is totally unscripted it is totally not prepared for very well i won't be cutting in and out i won't be including crazy b-roll i'm just gonna be sitting in front of the camera with a shotgun mic so i apologize for the semi-trashy audio uh and i'm gonna be explaining to you why the aio positioning thing has been blown out of proportion and uh and why you should not be crusading when you see a pc build that uses an aio that is not in the optimal position so there was a video released by gamers nexus which i think was very well put together i'm not disagreeing with anything that was said there uh what i am disagreeing with are the comments from people who have apparently watched that video and taking things out of context or just completely like pulled stuff out of thin air and used that video of his uh as this the spearhead to kind of drive this notion home so when it comes to aio positioning there is an optimal position right an optimal layout there is a sub-optimal layout which isn't bad for the pump and then there is a layout that is seriously bad for the pump especially if the loop itself is not properly primed and if there are significantly larger air bubbles than there should be in the closed system so to start with an aio has fluid in it right it's typically water-based and the problem is you can't really get all of those air bubbles out you you can kind of fill the loop up as much as you can but there's always going to be that small pocket of air that just doesn't escape now this right here positioning a radiator in such a manner trying to get this in camera so that the radiator is on the bottom and the pump is up here or any configuration in which the pump is higher than the radiator itself unless you have something else in the system that is higher than the pump this is bad because all of the air in the system will rise right air is less dense than water in a closed system that air will find its way to the highest point in the closed system which in this case is the pump right does that need any more i don't think it needs any more explaining i think we all understand this one now no one's arguing that this isn't good for the pump for the life of the punk we should say now the one that really drives me insane the one that i see so many people complaining about and steve himself has even said that people are taking this out of context they aren't they didn't understand what he was trying to say in the video this configuration right here this is the standard aio layout you can also i like to wrap my tubes around this way it just keeps things looking a bit more clean and i apologize i know it's not going to look very uh clean on video there but you get the idea where the radiator let's say is mounted up front and the pump is positioned in such a such a way that uh you know it's maybe two thirds of the way up from the base of the radiator but it is definitely not the highest point in the loop in fact in this configuration the tubes are as high if not higher than the top of the radiator so where you where would you expect air to collect in this configuration here it's either going to be at the top of the radiator or at the top you know somehow depending on how thick these channels are at the tops of the tubes if your tubing happens to run uh in such a way that you know it's higher than everything else which would be weird but i'm sure it's happening once or twice so in this configuration the pump is not in any immediate danger because air bubbles again if any existed in the first place in the pump when you turn your system on for the first time that air will more than likely assume this chamber isn't very big will be pushed out of the pump out of the block back through the radiator where it will collect on either side of the rad up top assuming this is again the way that you have it set up so the radiator is actually split down the middle you can't really tell but this chamber is usually sectioned off and that's to force water to flow through channels on one side right for that heat to be conducted or absorbed by the by the fins which are typically aluminum in these aios and then for those fins to then convect air or radiate air we call them radiators it's actually convection uh to atmosphere right so so that's what that's how our radiator works in a very simple sense and we use fans to accelerate that convection process so that that water will kind of work its way down one side it'll collect at the base uh here which is again joined and then it will flow back up to the other side depending on which which port is the inlet which port is the outlet um you'll have that circulation moving through so the air weather collect in the left or the right chamber the top of the radiator but again if it's a very temporary shot of air through something even when i'm building custom loop rigs there's a lot of air initially going through the pump not going to magically kill the pump right away the reason why you don't want air running through the pump habitually is because the pump relies on the coolant on the water-based solution typically with the inhibitors for for galvanic corrosion and the sort because they combine copper and aluminum in these things uh if you turn that water too much through the through the loop uh through through the pump then the pump will overheat so because it's not being lubricated by the water as much as it should be uh it will run too hot potentially over spool and die so i've got the video from gamer's nexus in question up right now we're going to play the section that i think is being misconstrued the most you'll see this is a very specific scenario in which barbs up is bad you'll see why it's you can actually see it in the video and steve actually addresses this at one point as well i think people have kind of glossed over it so here we go i'm gonna go ahead and play it and uh and then we'll kind of walk through it there's that then show is installed incorrectly when marketing its cases thanks to manufacturers doing this because it looks pretty and thanks to power supply shrouds requiring this configuration in many instances people often mount their coolers tubes up we always try to point them tubes down if possible and if it doesn't fit that way we mount it in the top of the case instead in this one we have to consider the location of the pump the pump is likely to be about one and a half to two inches below the tank which is a good thing you don't want the pump at the top that's okay anyway if the pump is sufficiently below the pump will be filled but air bubbles will occasionally get sucked through the outlet tube and into the pump depending on how it filters the air accumulates right next to the barbs this right here ideally we'd have it flipped so that the air accumulates in the other tank that isn't attached to the barbs and the tubes the air bubbles that get pulled through will circulate but this is the reason a lot of users complain about that water trickling or gurgling or bubbling noise this is really more about the noise than anything else in most instances it does cause performance issues as well but it's primarily a noise problem a performance issue it's a very like i know steve i felt like he had to bring that up because it is possible but it's it's a very very rare thing the loop would have to be so empty it'd have to have such big air pockets in it uh that that you would you would see a loss of circulation essentially uh but it's it's more or less about noise here and steve says it this is more about noise than anything else if you hear the gurgling it's because the air the the bubbles are churning up top on account of a fluid being pulled in through the intake barb and pushed out through the uh the little the outpour here on the other side so what's happening and he's showing you this in real time the air bubbles on this side are being pulled in through this barb down to the pump right so the pump is experiencing pockets of air like churning through the chamber then those pockets of air being pushed back up because air naturally rises when in water right air is a lot less dense than water so those air pockets are going to flow back up right into this side here now you can see this chamber is empty i mean there there is a there's a lot of air in here uh that this i would say is a poorly designed or it in the simplest of terms of poorly filled radiator the whole point is to have a closed system that is as you know little exposed to air as possible because air is inefficient in such a system so if you've complained about pump noise check for this orientation you can also get pump wine on some pumps when air is sucked through them and that might last past the period of the air getting pulled through in theory a small amount of air won't get pulled through because it's not a high enough speed to get sucked into the tubes but as the air cavity grows once it gets down to where the barb actually connects to the tank it can produce that bubbling and trickling noise that you sometimes hear as the air cycles through the loop fine right but that's right again specific to the aio so if the aio is not filled properly and both of those air pocket levels extend down into at least where that first barb is it's pulling in that fluid to the pump that's when you have that repetitive problem and if you hear the pump churning right when you first turn it on right that's the air that's stuck either from shipping or just the orientation that was laying on your desk that's the air that either migrated into the pump to begin with or is in that kind of intake uh little chamber there on the radiator it's moving through the pump to begin with but over time that closed system will equalize and usually it only takes a few seconds to maybe a few minutes now if in the upright position with the pump below the highest point in the rad you still hear churning and gurgling after maybe 20 30 minutes i'd be a little more concerned there that would suggest that again the loop is not filled properly and that some of those air bubbles are consistently being pulled through the pump and just circulating through the whole system over and over and over that's not good but that is a very very rare thing i have worked with aios since what 2014 2015 i've worked with dozens of them most of them have been in the stand-up config with the barbs up top and the blocks slightly below slightly lower than the top of the radiator right like steve said at least a few inches and i have not had a single pump die even if you'd say they were hand selected right i know this is a very small sample size you can't just extrapolate across the entire industry here i'm just telling you from experience i've never had a problem even with noise actually i've never even had a noise problem although i know that it does exist but it's not as common a thing as i think people are making it out to be and then they're taking the whole barbed up thing and they're just saying well barbup is bad period it's bad period no matter what when in fact it's only bad if the aio wasn't designed properly to begin with or more specifically wasn't filled up the way that it should have been to begin with but anyway i'm just i'm tired of seeing comments uh in regards to aio positioning where and it's it's perfectly fine if you want to say well the way you've got your aio set up um it's gonna be a bit loud okay usually the fans run louder than any gurgling you'll hear up top now again there are certain aios where we would expect that to be much worse and that could potentially be the loudest thing around uh but performance wise and especially when seen in the context of the life of the pump um that layout this conventional sort of like front mounted config is not bad um again the only thing you're going to deal with is the gurgle and that's only in a few radiators i haven't run into that really ever i've never noticed like oh that's a lot of a lot of air being you know collected and and gurgled in the top of the radio i just never noticed that it's not something that i've ever run into i think that's uh again something that people are blowing a bit out of proportion i didn't get the vibe that you know that that was being done in steve's video it's not what i'm trying to say again i think that that video was was put together very well i think that it needed to be made it was necessary but i also think that it's important that people don't stretch the truth or stretch the data in such a way that they you know have they create this narrative about aio layouts that's not true you cannot you cannot say that this is not ideal for the pump because the pump is not the highest point in the loop you cannot force air especially with how weak these pumps are most of these pumps are manufactured by asetek and they're they're relatively weak when you compare to a laying like d5 pump these are significantly weaker the closed system is significantly smaller typically than a traditional custom loop so to speak with but much wider tubing very large reservoirs things of that sort you need you know a lot more pump head to push that amount of fluid uh but i'm just i'm just sick of it it's just so annoying because this was never an issue until that video was made and now because people are taking that video out of context all of a sudden it's just being people are just getting destroyed in comment sections over this crap it's frankly garbage and it's annoying and i'm sorry if i'm coming across a bit snobby a bit uh moody i'm sure that's how some of you will construe this i wouldn't be surprised that's how the internet is but those of you who know me you know it's just after a while i can only take so much before something needs to be said and hopefully this video explains why what some of you are saying is not true um just just for very elementary fluid dynamics uh perspectives you just you're not gonna you know force air which is significantly less dense than water down it just doesn't make any sense unless you have a super powerful pump at which point you've got other things to worry about because uh i bet you these these connections here the connections on the pump side on the block side will fail much faster than uh than anything else so yeah before i break anything i guess that's pretty much it i'm sorry that this video had to be made i'm not expecting too much to come of it hopefully this clears things up if anyone is seen just spewing the crap about how a standard front-mounted aio is incorrect uh because that could damage the pump please show them this video i feel like if you show them steve's video all that you're gonna end up doing i mean steve's video is great by all means share that video but um i feel like if you show people steve's video who already believe what they believe by watching steve's video that's not really gonna do them any good because you're just gonna end up like you know reaffirming their initial position which is incorrect based on the information in said video but that's just how the internet works people take things uh uh too far or they they take things out of context and it just it it's very troublesome when you're in the media and you're subjected to that that sort of like slanted view of reality and it's like a cluster too because so many people will kind of gang up on you at the same time and tell you how it's wrong because i saw it in another channel or another video again the video is great but uh people are are stretching the truth and taking that information and just twisting it in ways that they shouldn't so uh yeah pump highest point in the loop that's bad okay all the air pockets are gonna rise to that highest point which would be the pump the block and if that pump chamber that that the chamber under the block is very small then you're kind of forcing those bubbles to kind of circulate through the pump or gather at least where the pump is circulating fluid and that's not good even if a small section of the pump of the pump blades is exposed to those air bubbles that could dramatically shorten the lifespan of said pump so that's why you don't want it you know in this config here where the pump is highest that that that's not ideal wouldn't recommend that and i will try to avoid that in the future if i've ever done that in the past i apologize if maybe i just couldn't get around it maybe that the case required pump assembly in this way or ai layout this way but uh whenever i mount a radiator up front don't freak out okay sure it's a tad bit risky when seeing the context of like audio like like how loud it is um just just sheer sound produced by the aio but um i've been doing this for years and i know plenty of others who have as well including possibly you and you probably haven't noticed any issues and it's because it's not really an issue for the pump might run a bit louder pump will be fine thank you guys for watching this one thumbs up
