i just finished setting up my pc and windows vista...
but every time is reboot the pc , the bios says that cpu fain fails or speed to low"

i checked the cpu fan and notice that i connected it to cha2_fan to cpu , instead of the cpu fan .... but when i switched connection to cpu fan... the fan did not work....

i think that my fan doesnt work properly but i want to have a second opinion before replacing it ....

Yes, if fan is spinning and temps are fine, just disable this warning in BIOS. My CPU heatsink fan happens to not have an RPM sensor so I had to disable it too.

On the A8N MB, you can set what you want the alerts to be for the CPU fan.
If you've replaced the stock CPU Cooler from AMD, then you may be "spinning" at lower than normal (for the 80mm fan) speeds. You can modify this speed through BIOS, or as others have suggested just turn it off.
