Need help watercooling a graphics card

LBT018

I currently have 2 g1 gaming r9 390x's, and the fans are annoying me to no end. Not to mention the temps are really hot with two of them. This is a custom pcb, and no full blocks are made for it. For my block I am going with the ek thermoshpere. This means i have to cool the mosfets and the vram with passive cooling. My problem is that I dont know what mosfets look like, and that I dont know where they are on my card. If someone could show me where everything I need to cool on them, that would be extreamly appreciated.

Might be worth waiting a little while, there wasn't an EK block available for my 970 ACX when I first got it, however it took around 4 months

okay. i had a similar issue with my 970's since no blocks were made for it. i also used that gpu block.

 

this isnt a g1 gaming 390x but it should give you a basic over view. your card wont be easy to cool. make sure your have little heat syncs on these or at lease direct air flow over them.

Id strongly suggest waiting for a full block. Using hybrid solutions on the 290/390's never ends well. The air coolers can hardly cool the VRM's as it is.... They are at the top of your card in a row, like what they look like to the left of your CPU socket on your motherboard.

The thing is, is that I really dont think they will make a full cover for this card. So to watercool them I need to go with a universal block. I am planning to put the coper heatsinks on them to cool the vram and the mosfets

ok found your thing and i am pretty sure this is all you need to cool with heat sinks (someone can correct me if im wrong)

ek has said they are not going to make a block for 390x but i agree with you the op shouldn't put a universal block on

Should I leave the cards how they are? I would much rather have them watercooled then the annoying wine of the fans.

yes. maybe turn down your overclock. but yes.

I will try that, I have the cards running at 1100 mhz

im not 100% sure thats all of the things you need to cool with a heat sink so just check again with other people just to make sure also again i would advise not doing this as it is a radeon card an they can handle less heat on the gpu than nvidia cards can.

There wasn't a block for my old Sapphire Vapor X 280X either. However I was able to use the block from a 7970ghz with a little modding, maybe worth checking the web to see if any 290x/390 blocks can fit

I will check, and what you circled was my original guess of where they were. Its just really hard to find information on this stuff because no one wants to put a universal cooler on a 390x lol

What did you do to your 280x?

I found a similar block and cut out the circled area

There is no water block for custom PCB designed 390/Xs. Only reference, which as same as 290/X.

Hmm. That really blows that they didnt make them for all of the 390's

I am going to do my research on everything that I need to cool on this card. For everything that needs passive cooling I am going to put copper heatsynks on. This should provide better cooling of the vram and mosfets better than stock, so I dont think that will be a bad idea. The gpu should be fine, as it is underwater. I just want to thank everyone who gave me info on the subject.

Since those 390s are refresh of the 290s, there isn't that much demand for it. Also, they run some what cooler that 290s, so no one plan to make block for custom PCBs.
