Ok I have an X1800XT in a DFI RDX200 MB (a PITA MB) and loaded up catalyst control center and noticed that its saying the temps are idling at about 50C and sometimes reaching 55C, this is with nothing running.. the fan seems to be spinning and nothing is obstructing airflow, I even have the cpu heatsink blowing in the opposite direction of the card.. I noticed there is a 3 pin connector on the card but I dont think its for the heatpipe fan since that fan is already preconnected.
