Lately I have had problems with my PSU fan (Corsair 650W, VS650, ATX-Power Supply). It starts randomly making loud buzzing or grinding noise, similar to this:

I've cleaned the PSU, even took it out to get best possible dusting, and it did not seem to fix the issue. Then I realized that earlier the sound appeared when my window was open and my computer had been off for a while (my case is on my desk maybe 20cm-30cm away from the ventilation window). Could the problem be, that since the temperature in my room has gone down (poor heating) the PSU fan is acting up? After all cooler the parts, more shrinkage there is, or atleast that is what my physics lessons have told me. And if this is the case, any suggestions to combat that? Other than "fixing" the heating, since I'm already trying to do that.
