I bet you smoke, or have the pc in a smoky atmosphere.
Your fan is not working efficiently because it needs cleaning - so your processor gets hot causing your fan to kick in more often:

If that really is not the problem, make sure the vents are clear - so the air can circulate. Keep it out of direct sunlight.
If it's a laptop, make sure it is not sitting on a squidgy surface - your bed, a cushion and so on, as this will block the vents causing it to overheat. Keep it on a firm surface.

Strangely enough, fans, the very things that are meant to keep the processor cool, sometimes get so clogged up with dirt, that they work overtime and end up producing more heat, which needs cooling...
So, is it a desktop or a laptop? Hopefully a desktop and you can simply take the back panel off (very easy) and apply a can of compressed air (about �3.50) to the various fans, grills and anywhere else that looks mucky. It could be the best few quid you ever spend :)

If your pc has a 478 pin socket CPU then you probably have the old retention module that the fan and heatsink fit into. This works with 4 clips that clip into each corner of the retention clip on the motherboard.
In dry, hot environments, these retention clips can sometimes break at one of the corners due to constant sprung pressure from the fan clips.
This would mean that your heatsink would be sitting off the processor by milimeters, enough to create a hot zone of air between the cpu and base of the heatsink.
Its the only reason a cpu fan can spin so fast and so loud as you explain.
If you dont have this type of fixture then i advise, cleaning the old heatpaste from the CPU and replacing it with Arctic Coolling paste. Easy done with the blade from a Stanley knife.
Good luck
