**Building a Custom Loop Water Cooling System with RGB**

I was excited to build a custom loop water cooling system with RGB lighting for my PC. I had already chosen the components, including the ML 120 fans and the Commander Pro fan hub. However, I encountered some challenges along the way.

Firstly, I tried to interface the RGB fan hubs with the motherboard, but it didn't work out as planned. I eventually found the RGB fan hubs that came with the ML 120 fans and managed to plug them into the Commander Pro thing via a hub extender cable. However, this created another problem - the other hub I wanted to use only had two of the three-pin RGB headers, while the liquid cooling stuff used a four-pin header.

To solve this issue, I considered using a converter that could translate from one type of header to another. Unfortunately, this proved to be a problem as I accidentally broke the only header on the motherboard that supported it when trying to plug in the converter.

Despite the setbacks, I managed to get the system up and running, albeit with some minor issues. The fan won't light up for some reason, but I'm not sure what's causing this problem yet. Additionally, the middle fan also refuses to turn on, and the motherboard lighting is limited due to my inability to install MSI software.

Temperature-wise, everything seems fine - the GPU is hovering in the mid-to-low 40s, which is great for a 6800. The CPU, however, is running at around 73 degrees Celsius, which feels quite high. According to some research I did on the internet, this temperature is not uncommon for custom loop cooled CPUs.

In the end, the system looks amazing, and I'm excited to get it up and running properly. To see how well the system performs in practice, I'll be streaming later today with some games. You can check out my Twitch link in the description below for more information.

**Note:** I will be editing this article further to make it more readable, but I have tried to preserve the original wording as much as possible while reorganizing the sentences into a coherent structure.

WEBVTTKind: captionsLanguage: eni've had a bit of a tumultuous history with custom loop builds on this channel so when corsair reached out offering to send over a bunch of stuff for a loop and a video uh i had some mixed feelings on the one hand i was like hell yeah i want to do a custom loop build and then on the other hand i i was terrified because i still haven't really recovered from my petg fuels nightmares but then i thought why not just take the easy way out and do a soft line build uh something that i've never done before and then i'll just pretend like i'm doing it because i prefer the look of it and not because i i still have night terrors now this custom loop has been months in the making because corsair told me they can send me anything my little heart desires aside from a graphics card and a cpu now luckily these two things are an abundant supply at the moment so it definitely didn't take me forever to find them i actually have to specifically thank mr wallman for this rx 6800 because after an intense bartering session i was able to convince him to send me this beautiful rx 6800 which corsair does make a block for cpu-wise we're using a 5900x something that i'm extremely excited about i was able to find this on craigslist for below msrp well i mean a little bit above msrp but it was without tax so technically it was less than buying it new which was pretty exciting and it was on it was just unopened um can't wait to get into that motherboard wise i've actually already got the 5900x in this msi x570 tomahawk board which has a nice black aesthetic it's one of the reasons why we're going to use it and then finally corsair sent over a bunch of custom loop goodies and with that let's assemble the system and do a test fire before we get started on the loop hey okay now that we've confirmed that everything is live and well it's time to get the blocks on the cpu and the gpu and here's the block which you know it looks it looks pretty nice it's more plasticky than i'm used to but you know i guess that's fine it's not like it needs to withstand a prison yard shiv battle now i'm not one to waste so i'm gonna use the pre-applied thermal paste which is in this kind of triangular pattern i guess okay that is a very mounted block um and then as is tradition with rgb there is a cable that we need to deal with um yeah i'm thinking of just kind of trying to run it under the block up the top okay i think that's a that's a reasonably well hidden cable but of course before we get the block on we have to remove the stock cooler okay we are about to break the card's virginity here there we go oh that's interesting this pcb actually has rounded off edges i don't think i've seen that on a gpu before it's it's pretty cool okay here is the underside of the cooler and they actually do use a thermal pad for for the gpu which i think is pretty cool unfortunately i did break it in the process of taking the the cooler off that's fine we're just gonna replace it with thermal paste anyway and then here is the actual graphics card oh what a beauty look at that gpu ooh this is starting to look really good there's something just awesome about blacked out pc hardware and i think with that tubing it's going to look amazing in that case um so yeah with that let's start building the system into the case the 5000 x and here is the case that corosair sent over not entirely sure i like the way it looks i don't think it's going to match the aesthetic of the build very well but i chose it you know my bad i'm sure we'll figure out some way to to have it match the aesthetic we'll figure something out so okay so after what can only be described as a gratuitous amount of swearing and heart palpitations this is where we're at i had to end up ditching the second 360 millimeter radiator because otherwise it was going to be an absolute cluster kerfuffle over here uh tubing wise and stuff so yeah this is going to be much easier to route uh the pump res combo is a little bit tiny and it's hanging a bit skew over here uh but it it all is gonna work out i think so i think i can start routing tubing and hopefully trying hard not to jinx himself here i think this is going to be the easy part um considering that it is soft line and all but yeah i think it looks real amazing i am very excited to see how this turns out oh yeah on a side note i do have both of the radiators set up as intakes so that we have some serious positive pressure in this case this fan here is going to be the only one doing any exhausting oh use some welly to get that on oh we can celebrate tube number one is on and it also kind of acts as like a gpu rest yo i've used this fitting in literally every custom loop i've done top tip when it comes to doing up really rough fittings gloves like this with with nice grip on it does help a lot so let's pour in some water oof there's always something extremely nerve-wracking about pouring water into a pc it feels so counter-intuitive it's like this is the last place you should be pouring water and we already have a leak where is that coming from oh it's coming from the actual fitting though so it's coming from this bit i just need to tighten that up it was a very minor leak this is an old fitting and i just didn't re-tighten it properly but other than that it seems like we're okay there we go that's why we got the paper towels i actually almost didn't use the paper towel okay so now i'm gonna actually start the power supply i've got everything unplugged on the power supply end aside from the pump okay there we go nothing else seems to be leaking i always get phantom wetness like it's like when i feel fittings it feels like i'm like even if they're dry it feels like i'm sticking my hand in an aquarium more water into the res cycle number two again phantom witness for days oh big big big ass bubble in the block there you know that is like oh it is overfill but that'll that'll drain uh there's still a lot of air in the loop so it's gonna take some time now unfortunately this fitting is uh is actually leaking it's the fitting joint over here that's leaking and i do not feel like replacing it so i'm gonna be super ghetto here and a lot of you are probably going to hate me for this but i'm just going to use like plumbing tape i've got this stuff which i'm going to cut smaller and then i'm just going to do a little bit of a loop around there and then i don't have to drain most of the loop to get it out even though it is soft lined so it wouldn't be super difficult to do i am just at the end of my tether so i'm gonna do i'm gonna do this okay so let's try again here i'm gonna go like that it's gonna come around no one will be the wiser here except for the fact that i'm showing all of you what i'm doing should fix it it is a very very minor leak okay now i'm gonna give it like 20 minutes and see what happens it is now the next morning it's been running uh overnight and it seems like the fix has worked we haven't had any leaks from there we haven't had any leaks from anywhere in fact i've checked up here as well so yes we have a successful custom loop that only had two minor leaks uh so yeah now i just need to go around the back i need to fix this abominable mess back here and then and then we can see how this loop actually works it's exciting let's see if it works um it'll be amazing if it just boots up on first try so yeah let's keep fingers crossed oh i mean i obviously need to dial in all the rgb i'm not going to have it on rainbow vomit in such a black build none of the fans are spinning up which is always a good sign uh i need to open the backward game now i'm going to take this moment uh to just briefly rage quit on rgb because it's the dumbest in existence first off i decided to use this hub in here which is the rgb hub that comes in the case but for some reason i couldn't get the rgb hub in the case to interface with this hundred dollar uh commander pro thing uh which is already a pain in the ass that you need a hub to plug all of your hubs into so that they can create a hub world and then they can do raids and warcraft together or whatever but so that thing didn't want to talk to that thing and when i plugged it straight into the motherboard then the software ignored it it just pretended like it didn't exist now again i am very much down to accept that this is due to me being stupid because that's very likely but still i couldn't get them to interface so then what i did is i went and found the the rgb fan hubs that comes with the ml 120 fans in here so this i was able to plug into this commander pro thing via the like hub extender cable that we have over here i don't know if that works yet because i haven't powered it up yet because i have a different problem i wanted to use the other hub to plug all of the like liquid cooled rgb stuff in but the problem with that as you can see here we've got a 4-pin rgb header whereas all of the liquid cooling stuff uses a 3-pin rgb header so i i couldn't plug that into that hub and this commander pro only has two of the 3-pin rgb headers but you have to use the 3-pin to plug this hub in that doesn't support the other three pins so now i only have one spot left for all of the rgb stuff to put in there but there is another option you can use i have one somewhere in this complete mess of cables um oh yeah i've lost it i don't know where it is but basically it's a converter from this thing to that three-pronged rgb header that motherboards use but the problem with that is those headers also suck ass so when you try and plug it in i accidentally broke the only header on the motherboard that supports it the reason for that is because you can only start fixing all of the rgb rubbish once you finish the entire loop and the system actually can boot in right so at this point you don't know what dumbass mistakes you've made hooking up the most complicated contraption in the universe so then you have to like reach into all these little holes around cables and stuff to try and get header get to headers that aren't readily accessible and then it just means that you break and after all of that it does admittedly look really amazing but this fan won't light up for some reason i don't know why i triple check that it's plugged in it is plugged into the rgb hub i've got it configured in the software but no it just doesn't want to join the warcraft party raid okay i've had some cheese i've recovered i am no longer in my rgb induced rage and now i'm really happy with the result i think it looks very cool i still couldn't get the middle fan to light up for some reason but again i couldn't really be asked at this point to do anything about it the same goes for the lighting on the motherboard i couldn't be asked to install msi software at this point to change that color uh i guess we're just gonna have a bit of a hint of green in here until i can build up the courage to go back into it i'm not gonna spend any more time talking about the rgb because otherwise i am going to just pop a blood vessel in my brain i will say that all of it's probably due to user error temperature wise it's fine uh with gpu wise it's hovering in the mid to low 40s which is really good for a 6800 as far as the 5900 goes the the cpu in here it's it's at about 73 degrees celsius which kind of intuitively feels quite high for a custom loop cooled cpu but the 5900 is like trying to cool a small sun it seems like from a bit of research that i did on the internet so i feel like that's a fairly standard in-line temperature um yeah again i think it looks amazing uh if you want to see more performance related benchmarks i didn't have time due to all of the rgb shenanigans to actually properly benchmark the system so i will be streaming later today on the pc and i'll try out some games and you know so that you can see some estimate of how the system actually performs uh so i'll have my twitch link in the description below if you want to check that out with that i think i'm going to end off the video hopefully i can figure out a way to edit all of this in time uh thank you corsair for sending out the custom loop stuff and until the next video bye-bye youi've had a bit of a tumultuous history with custom loop builds on this channel so when
