I recently built a new computer and installed an ASUS R9 290 DirectCU II OC videocard. When I power up the machine, other fans in the case - two chassis fans and the CPU cooler fan - turn on immediately, but the graphics card fans don't budge.
I double-checked the auxiliary power connections; they are both tight and have a green light next to them on the card, so that shouldn't be the problem.
I have a display plugged into the card, and it seems to be functioning normally: the screen showed the UEFI BIOS just fine, and I used it all the way through the Windows 7 install process. Once Windows was up and running, I installed the GPU Tweak program and drivers that came on a CD with the card, and the fans remained stationary. I even ran a few minutes of torture tests and watched the GPU temperature climb to 80 C, but the fans still won't spin.
Is there a possibility that I have a corrupted config file that could be fixed through software, or is this a hardware issue? Should I ask for a replacement card?
