It may be some thermal expansion issue. Try reseating your cooler/s and making sure that your fans aren't loosely attached.

What kind of noise is it? A sort of humming sound? A grinding sound?

Sounds like a problem i had with some cheap hard drive cooler. The fans would make noise for a couple of minutes and then stop. Its prob a fan issue where the bearings are going in the fan and it makes it have a slight wobble and that in case makes a mid to high pitch whining noise almost a grinding noise but once it heats up to other bearings will expand and let it sit tight again. Most likely your gonna have to replace the fan on your CPU. What CPU you running? I can help you pick out a cheap but effective cooler.

It's a short humming sound for 2 min..

Sounds to me like the CPU fan is hitting max, then reducing itself. This is normal but like others have said, if the CPU fan is old, then the bearings will be causing a louder than normal sound. This is confirmed by you saying it is getting worse day by day.
