Hi all,

Put together a build out of spare parts I had around and the CPU fan is in overdrive. Sitting in login screen and it runs loud and fast for about a minute before slowing. The second I insert a disc it speeds up crazily again.

This build was working just fine about 2 months ago and running quiet too.

What could be the problem?

Regards
