Hello, I have a PC with following specs:
Windows XP SP3
Intel P4 CPU @ 3.06GHz

The problem is that whenever I turn off my monitor, my CPU fan starts roaring off loudly even if there are minimal apps running, ie, the apps that usually run on boot. How do I reduce the noise?

Thanks in advance.

The heat sink fan assembly needs to be cleaned out...!

I don't think there's a problem with the hardware because it remains cool and silent when the monitor in on. The problem is monitor-specific. Recently I heard of some software that can bring down the noise of computer when it is running unnecessarily.
