I have several GTX 480 in a box without a monitor. I need to set the fan speed for each of the GPU.
I have not been able to do this successfully. There is a thread here The Official NVIDIA Forums | NVIDIA that says it is a problem that nvidia still need to fix.
how can people use cuda for linux number crunching if they dont have fan control?!?!?! the reason i chose linux to develop was so i can avoid these silly display type issues.
