3 pin or 4 pin?
disconnect them all except 1 of the cpu fans. make sure its on the cpu header and that its working correctly. reconnect one at a time and make sure the bios is set for pwn 4pin or dc 3pin for the header based on what the fan is.

Sounds to me like maybe he's got a 4 pin fan set to DC and the voltage is fluctuating.

Thank you for your comments, the asus fan is set to 1100 rpm with the xpert 2 program, the system behaves like this with idle. I turned off all of the fan settings in the bios. but when I increase it to 1200 rpm and above this problem is fixed, but I cannot adjust below this level. my fans are all arctic brand and 4 pin versions.

Does xpert have a setting for pwm vs DC? You need pwm selected.
