gtx 480 fan control headless

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 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.

there is a website here that might offer a solution. how come nvidia dont support headless boxes though? doesnt make sense to jump through these hoops.
