HOT Video Card on custom loop

Phaeda

Go to solution Solved by Phaeda,

Update for anyone still following this topic: Solved.

Basically the issue was all flow. The Coolant in the GPU block wasn't moving very quickly, which let it heat up to the point where the card would almost fail. This didn't make a lot of sense to me since I just bought a new pump that was turned up to the max, but after draining, cleaning out the loop and refilling, I noticed something.
Right at the end of the loop where the coolant would lead back into the Res, the coolant was literally TRICKLING back into it.

I solved this with my handy friend. Remember that old pump that died? Well she's back in the loop now. In fact I have both pumps in the loop, as you can see in this image: http://i.imgur.com/SNTgFPU.jpg

Check out the Res, the water is POURING out. Much better. This was a silly idea to me, and originally suggested by my brother. The idea is that even though power can't get to the old pump, (because it's broken) If you force water through it, it will still spin. So essentially the new pump is pushing water through the old pump and forcing it to go, increasing output.

Also if you're wondering about temps, CPU idle is about 25C, 60C under full load. GPU is about 30C idle, and 65C full load.

Thanks for everyone who suggested ideas.

Hey guys,

 

Recently I got a r9 290 from my brother, and decided to get a waterblock for it so I could run it in my loop. The block I got was a EK-FC r9-290x full cover block.

I also invested in a pump, because the last one finally died after about 3 years of use. 

 

After assembling everything, and bleeding the system for a couple hours, I started it up and everything was going OK.

Soon after I noticed the video card start to heat up, very gradually, despite being at 0% load. Basically it just continues to get hotter and hotter until it sits at around 85C.

If I try to load a game, or do anything graphically intensive, the card shoots up to 95C and stays around there.

 

I figured there was an issue with MSI Afterburner, which I was using to monitor the temps, however upon placing my hand on the card, it was evident that it is very hot and is giving accurate information. The next thing I tried was bleeding the system more, and I was able to get some more air out by taking off radiators, GPU and CPU blocks and shaking them around, but this didn't make much difference.

After looking online it occurred to me that I could have simply not attached the GPU block on properly, or that it wasn't making good contact, since the CPU wasn't having the same issue. I finally decided to try and reseat it. After unscrewing everything, I could very clearly see indents on the thermal pads from the card being up against the block. The thermal paste was also spread out evenly which I take as a sign that it's making strong contact with the block.

Once I put the block back on, I tried feeling the block, as well as the card. They were both heating up, so I know the heat is transferring from the card to the block efficiently. 

 

I'm pretty much at my wits end with why my Video Card is getting so toasty. The new pump (EK-XTOP D5) is working well, which I know because it has a speed controller, and I can clearly see the Coolant moving. The only other thing I can think of is that maybe the layout of my loop is inefficient, and thus the Coolant isn't getting cooled properly. Or perhaps the Coolant is simply stationary around the Video Card and isn't able to complete the loop back to the pump. 

(For reference the loop goes: RES>Pump>GPU>RAD1>CPU>RAD2>RES)

I am including pictures of the system/loop, and any help or suggestions would be very appreciated.

Did you apply new thermal compound?

 

Also, sexy build.

 

Yes, after I reseated the video card I applied new compound. Same thing for the CPU.

Also, thanks. (:

Oddly it doesn't seem like the fans are making much difference. I have four on the dual rad in the top all running at max speed, but they aren't really affecting the temps. I took all 4 off earlier to bleed that rad, and the temps were the same without them on.

Only thing I can think of is water isn't flowing inside the block.

pull the gpu block off clean the block off and replace the thermal pads for the mem/vrm then check to see if they are making good contact lightly press down . if so put paste on and screw the card back together . the only other thing i can think of would be you dont have enough rad space to cool gpu+cpu . do you have a water temp sensor you can install to check that since if thats abit above room temp or at it then your gpu block ant together right

he should have no problem with flow i have more on my loop then he does . but if his pump is faulty  thats a different story

It shouldn't be faulty, the thing is brand new. Also, I can very clearly see and hear the pump spinning, especially when I change the speed.

What spesific 290 where you given? some aftermarket cooled cards use components that don't agree with reference blocks even with reference PCB layouts.

System CPU : Ryzen 9 5950 doing whatever PBO lets it. Motherboard : Asus B550 Wifi II RAM 80GB 3600 CL 18 2x 32GB 2x 8GB GPUs Vega 56 & Tesla M40 Corsair 4000D Storage: many and varied small (512GB-1TB) SSD + 5TB WD Green PSU 1000W EVGA GOLD

Asus R9 290.

According to EK, where I got the block, it should be compatible. http://www.coolingconfigurator.com/waterblock/3831109869031

Was it a stock card or an DCUII?

Where do you live?

Whats the ambient there?

Because I dont think a 360mm rad is enough for a 290 and cpu...

Are you high?

 

Edit 2 r9 290 chips can run off a single 120mm and each one of them puts out quite a bit more than a overclocked Intel chip.

Canada. It's about 19C right now.

I thought so too, and I have an extra 120 rad like the one on the left. I tried installing that as well, for a total of 480mm rad space, but I still experienced the same issues.

Very good that card is compatible the DCUII card with the aftermarket cooler has VRM clearance issues with the block you listed that I thought might be causing your issue.

I had a similar thought, do you think changing the tubing orientation on the block would help at all?

Well I would say try, and are you sure that the water is flowing?? ( I think you should be able to see some air bubbles )

I see what you were getting at, thanks. I didn't have any issues putting the card on, and it seems to fit flat against it. I'm thinking the problem is flow, not the block itself.
