As you may or may not know i own an Intel Celeron D 335 Processor, overclocked to 3.5Ghz. And to cool it, i use a Zalman superflower fan.
Well, i decided to play around with the fan controller, and run some CPU intensive programs.
My CPU intensive program is called United Devices, cancer reasearch program, etc. It basically uses all the spare processing cycles to do its work.
I turned the fan speed down from 2600rpm on my CPU to... 1300rpm.
