When I'm using Microsoft Virtual PC and installing Windows XP in a virtual machine, the temperature of my Intel Pentium 4 1.7 Ghz went upto 130 degrees. I have a CPU fan (about 3000 rpm) but the temp goes on increasing. The temp of MotherBoard also went to 55 degrees. Is this normal when running intensive CPU programs?? If not, how can I keep my CPU cool in such conditions?? PS: I haven't overclocked my CPU.
