I bought a retail AMD 64 3200 Processor and it came with a fan. I have it plugged into the CPU_Fan header on my motherboard (ASUS A8N-SLI Deluxe) and it spins up like normal. I have the Q Fan control option turned on in the BIOS. When I boot up, sometimes I will get an error message that says my CPU fan may not be working well enough. In the BIOS Hardware monitor, it says it is spinning between 1400 and 1500 RPM. Using the ASUS Probe utility in Windows gives me similar speeds. Is this too slow? Is there any way to manually speed up the fan? It seems like it should spin faster than that. My CPU temp is at 39 Celcius so I don't think it is causing a problem, but some info would be good.
