CPU Fan spins too fast

[Red]

I don't trust 100% to viruscanners, some does identify the virues and some doesn't, i had a virus on my pc which no virus scanner could find, i tried multiple scanners, Avg, Security Essentials, Norton etc, etc.
In the end i had to reinstall the os and that finally fixed the problem.

If the issue doesn't get solved, i would recommend to use either backup, (if you have one), or reinstall option.

But if the problem appears still after doing it, it might be more of a hardware problem.
