Remounted both cards and it resolved the issue. 28C on idle 60C with a hour under full load
I found 2 loose screws under the problem cards backplate holding the block to the card.
Thanks for the reply's everyone
Hmm yeah the order of it going back and forth with the temps is whats got me thinking. I wonder if the air in the line was the cause for the first temp increase but getting that hot then being benchmarked also loosened up the contact to the block.
Would also explain why the second time the...
Didn't think about pulling the power from the other card all together Ill give it a shot. I only set this loop up to test the cards as I have a new case mod in progress but still need to get some stuff including new pads (was going to remount before putting into new mod)
Cheers
Yeah I got a...
Im pretty sure it will come to that just seeing if I can avoid it haha
One thing I didn't mention
GPUs are used, came mounted to ek blocks. Fedex left them outside and they were ice cold when I got them, condensation was forming on tops of blocks. (I let them sit for over 24hrs and blasted...
Have a issue here that I haven't encountered before. After hours of fiddling I'm gonna throw up my hand and ask for help.
NOTES
CPU and GPU's are on water
One card is running super hot idle & stress, then it was fine, then it ran even hotter...
GPU = EVGA 680 X2 (1 running at 45-90C when main)...
To anyone looking at this case with water cooling in mind I have just picked one up here are my initial findings.
Dual 120mm Fan Mounts
-Can support a slim (30mm thick) style 240 rad with 2x 20-25mm thick fans (both sides)
*exceeding a total thickness of 55mm per rad will cause clearance issues...
Lian Li PC-V359WB Black Aluminum Micro ATX (NEWEGG)
Lian-Li Global | PC-V359 (Lian-Li)
Im looking into doing a rebuild using this PC-V59WB from my PC-354B case with W/C options in mind.
Anyone have experience doing a build using this case? Any annoyances particularly when factoring in a W/C...
Got a good offer on a XFX HD 7970 with EK-FC7970 Full Cover Waterblock & EK Backplate. Ill give XFX and AMD a go again.
Thanks for the offers everyone I got what I was looking for :)
If it were me I would buy a new quiet fan just to be on the safe side. I personally like Noctua fans but there are other more affordable quite fans.
Or just pull it, stress everything on the system for at least a few hours and see where the temps are at for all the internals and the case...
I actually like it a lot more now haha. When I pull it to replace it with a newer card on water ill give it some more stickers and keep it around for a tester or another build ;)
So she is up and running. Stress test @100% GPU&CPU for 10min and wont go past 66C (been at that temp for 5 min)
Better temps than I was getting with stock fan when it was new!
If anyone is interested I used the fan out of a XFX 8800 GTS shroud I had kicking around. Fits just right and 2 out...
