Computer CPU rpm question.

Hello,
I've recently encountered a problem. Im monitoring my dekstop cpu fan and it suddenly drop's to 0 rpm and then spikes back up to 3400+ rpm and it's really noisy. Also i've monitored my cpu temperature and its normal when gaming no more than 60c idle is about 41c. It started happening often enough with those pesky spikes, also often enough there is no spikes at all. I just want to know why my computer cpu fan started dropping to 0 rpm and spiking at rpm back up. Anyone could help me out here?

Ars you sure it's not running at all? I've heard of video card fans not running but cpu fans should be running constantly. What are you using to test fan speed?
