I'm using the HP D530 Motherboard/CPU that I installed in a new case with a 600W PSU.

There was a problem with the onboard chassis fan connector (3-wire) not supplying sufficient power to the chassis fan indicated by the fan spinning very slowly, but I never experienced the "512 Error" at boot. Also, the same fan works perfectly connected directly to the PSU.

I disconnected it since I already have plenty of fans connected via the PSU directly. Since then, on startup, I get the error: "512 - Chassis Fan Not Detected" and am asked to "Press F1 to continue". This gets quite annoying since I use this machine remotely (w/ FreeNAS).

What could be causing the onboard fan connector to not be giving enough power? If this is unable to be corrected, how can I make the BIOS think there's a chassis fan plugged in without actually plugging a fan into the onboard connector? Would it be possible to jumper the pins without damaging the motherboard or PSU?

Thanks,
Erik
