Well, there's the obvious one: Clean out the dust.

But some more info would help:
Is it a laptop, or desktop, is it out in the open, or in a closet, etc.

Worst case: the thermal paste may need replacing.
Or the fan may need reseating.

Also: which project is causing this?

Look and see if there is a gap between the CPU heat spreader and the bottom of the heat sink. That actually happened to me and a copper shim fixit the problem until I found the correct cooler. I had the exact symptoms you mention.
