I'm currently running an Asus GTX 280 on which I installed an Aquacomputer Aquagrafx 200 water block. I just did a short functionality test with the card before I installed the water block so I can't say much about the behaviour of the card before installing the water block except that the card basically seemed to work - which it still does.
Everest and GPU-Z are however always reporting a 0° GPU temperature which jumps around to 64° sometimes in Everest and in GPU-Z also sometimes to 192°. So basically I always get a reading of 0° (most of the time), 64° or 192°.
When playing GRID the game stutters a bit.
I also had a BFG GTX 280 in this PC with stock air cooler and the temperature was fine with this one and also no stuttering in GRID.
In another board I read about someone with the same problem, the guy also got an Asus card, I don't know if he has installed a water block tho (I guess not). http://www.computerbase.de/forum/sho...d.php?t=434616
Does anyone else have this problem and maybe has a solution or knows what is causing the problem?
The GPU surrounding/PCB temperature is correctly reported btw (37°).
