Just put together a new system and picked up a VisionTek HD 5770 video card. For some reason, the moment I turn on the machine the fan on the GPU runs full blast and it's very loud. I know it's not overheating because it happened since the day I built the machine and well as being off for hours before trying again.
I'm not noticing any other problems in this system. The card does have the 6-pin power slot on the back of which my power supply has a PCI-X connector for.
If I go into the ATI Control Panel it actually shows that the fan is running at 35% and the temperature is 45 C. If I enabled "enable manual fan control" and boost it to 100% or put it down to 0%, I don't hear any difference in noise but the app reports that the fan changes do occur.
I've since put my old GeForce 7800 GT card back in and connect the PCI X connector and it's finally quiet again.
I have a ticket open with VisionTek but wanted to see if anyone here could offer any guidance before they respond.
