 Heron's graphics card was running at like a hundred degrees idle while water cooled, but the water still has to run through this Graphics card and see how terrible it is. Can you see the floater right there? It moves around if you tip the card Oh the metal touch my skin But the problem that I have right now is the plan was to just remove the graphics card from the loop Put another graphics card in there and then have the loop go through this non powered graphics card Which would hopefully not add any temperature to the loop and then it would be fine But I don't even want to run this computer on the full loop if it's this gunked up Corsair delivers real necker. Oh here I have one ha real neck or nothing with their new strafe mechanical keyboard featuring genuine German made cherry MX key switches Click on my chin to learn more. I'm gonna move my chin now. Just the three for a loop At last my friends it is finally Finally here the conclusion of the whole room water cooling system series of videos that we have waited Over a year since initially putting these systems together to finally talk about whether or not the concept worked whether or not in practice it actually worked and The wait is over only a couple more minutes It kind of reminds me of that that BMW video that I was teasing on social media not that long ago But the only one series drop a like on the bottom of the video if you want to see us finally release that because I think We're very close Let's go So I want to do a recap of the concept for those who haven't been following along the whole time our editing den is in a south facing room of the house that we have been running Linus Media Group out of for the last year and a half and it gets friggin hot in here So my brilliant idea was what if we took all of our editing workstations and removed the heat from the room via water cooling? So it started with redoing our editing workstations Which used to be just a haphazard mix of parts that we had left over from reviews and are now pretty much all standardized So they've got n600 cases from Cooler Master water cooling by Swift tech And I'll explain why there's a radiator on the outside of the system in spite of that's the whole room water cooling I'll explain that later We've got 4960 x 6 core processors Those are extreme editions 32 gigs of Kingston memory a su sex 99 deluxe motherboards DTX Titan black so those are 6gig VRAM cards We've also got Cooler Master V 750 power supplies and all of them except edsles which actually has two of these a quadro a 10 gigabit nick and then a V 1200 because his system is kind of balls to the wall and then each system has its Own pump as well so the way that it all works is that at the back We've got kind of a a tangle of tubing going on here, so we've got quick Release fittings here, so we can either connect to the radiator on the top Which is running quite toasty right now or to the whole room system and this was actually all done up by Luke's dad who did an amazing job of Plumbing the entire room for us so you can see the terminus station is actually over here By Nick van burkel's PC So every one of these systems has an inlet and then an outlet and they all join together as you go around the room We actually left enough space to have up to seven Systems water-cooled all at the same time all on the same loop and in the bathroom Slash server room this is where the magic happens, so here's our mechanical and then UV sterilizing filters here is our reservoir here are dual little giant pumps And then those lead to a radiator fan setup using noctua industrial PPC fans So those waterproof dust proof ones on the roof of the house so that we are actually Physically removing the heat from the building in order to keep our systems cool We've got a cover on there We've got a power supply for all of the fans to run as well so with that recap How does it perform so to evaluate our success? There's a number of different metrics to look at we can look at the cooling performance of The individual systems based on how hot their CPUs run during an intensive task like video rendering We can look at the room temperature Inside versus the temperature outside to see if removing the heat from the room Actually yielded any kind of benefit and we can look at the convenience and maintenance factors So let's start with CPU temperatures when we're running the CPUs on their own Radiators the room reaches a temperature of about 31 degrees So you can actually see that right now Which is about a three degree difference between the inside and the outside and you should bear in mind that that's on a day That's not particularly sunny which can cause the room to heat up quite a bit more than the computers could possibly affect all the systems and the sort of 45 degree plus range on the CPU which is reasonable except for Taron's Which I'll talk more about later and Edsel's which has an additional graphics card But no additional radiator space for cooling so that one's bound to run a little bit on the hotter side So now what we're gonna do is we are going to take the running whole room system I'll show you guys how we quickly connect and disconnect them So while they're running probably not recommended, but we've done it so many times anyway that it I've lost all fear of the process all we do is use these to hook it up to the whole room system now What you are likely to see here is a nearly instantaneous drop in CPU temperatures So we've gone from 47 on core 1 to 41 and I'll make some graphs here showing you guys the difference in CPU temps under load from system to system to dramatically reduce temperatures Across the board by hooking up to the whole room system. Why does that work? Well, it's just a matter of radiator capacity we could just as easily achieve Great CPU temperatures by hooking up much much larger radiators as you'll see in some very large towers This will support like quad Rads in the front duals in the top a single in the back and the like another Advantage of this approach by having it outside is that you don't end up with a chain reaction of the room temperature increasing and therefore the cooling efficiency of your radiator increasing because you're always tied to ambient temperatures, but That's a great question if one of the objectives was to lower the ambient temperature in the room with this system How much have you achieved the answer is not a heck of a lot we achieved a one degree Drop by hooking all of these systems up which I would consider within the sort of Margin of error that's sort of a vague sort of concept. So being able to align this correctly helps a lot On our inlet. So that's the cold side. We're getting 29.7 degrees And on our outlet That's the hot side We are getting 30.0 degrees, which i'm sure someone out there is calculating The specific heat of this, you know mass of water or whatever the case may be and i'm sure that we are actually Dissipating a significant amount of the heat outside But that is where the whole was it actually practical thing comes into play because By going with copper tubing, which I think we can all agree is more aesthetically pleasing than Insulated pvc we actually created a situation where we are dissipating a significant amount of the heat We're pulling out of each system Into the room Anyway, anyway via the copper piping So I guess all that's really left now is do we consider the project a success? The answer is no. I still think the concept could have worked really well But there were a few critical things that I really think we could have done differently number one Don't use a metal reservoir Don't use a metal reservoir don't use a metal Reservoir find some kind of plastic reservoir to use because that's where the thing that I promised to talk about later comes in Taron's system has some big problems caused by corrosion bits stuck in his system that Even cleaning out his cpu block which was extremely gunked up. That was a picture I posted on instagram could not fix and um Point number two is I would definitely recommend installing some kind of a bleed system At the highest point in the loop that way you are not going to have as much difficulty filling the system each time Uh compared to us where we had to add a second pump in order to have enough Flow rate and enough pressure in order to get the water in and the air out of our tubing system the other thing that I would do differently next time is um Um wow gee I guess that ties into a question that we've been asked a lot aren't you guys moving? Why did you bother with all of this and are you going to do whole room water cooling at the new place? Well number one we weren't planning to move when we originally came up with this concept and started working on it so There's that uh number two No, we do not intend to water cool our systems let alone whole room water cool our systems at the new office We're going to have air conditioning which is probably the solution that we should have gone with in the first place If the objective was to lower the temperature in this room And have our computers run cooler So I think that's pretty much it. Thank you guys for sticking with us throughout the whole room water cooling project We learned a lot. I think we established the feasibility of it the performance and the silence factor cannot be denied but the convenience factor of it leaves a lot to be desired and the The execution of it would be extraordinarily time consuming and even more expensive than what we did If you were to really do it properly in such a way that it would require little or zero maintenance over the long run Thanks for watching guys.
