I am installing an AMD Athlon 64 3200+ on an ASUS A8N-SLI Deluxe MB. The POST message is saying that there is no CPU fan, but it is there. I have seated it as best I can and clamped it tight. It is plugged in to the CPU_Fan connector on the motherboard. But the voice POST still says there is no fan! I used Arctic Silver between the heatsink and CPU, and I don't think it is leaking out anywhere -- I have double checked.
Any idea why it still doesn't see the fan?
