It is a heat-sensitive/system-controlled fan and stops spinning when the CPU is cool enough?
 
I think that may be the case. Normally, this is common with AMD processors that use their Cool n' Quiet technology. Dunno about Intel though.
 
got smart

i ask my friend 2day, he said my intel cpu got smart ,if less program will consume less power but dont know whether will stop for few second and spinning again??anyone use intel cpu???thanks
 
Once the fan stops, the CPU gets hotter and the fan needs to start up again?

The thing is, you can't run an electric motor at an infinitely slow speed. So the fan has to start and stop instead of just making very slow turns.
 
I have also seen power supply fans do the same thing... Its a nice feature actually. Keeps the fan noise down a bit.
