My 430W Enermax PSU has 2 fans, obviously. Sometimes, when they gather dust, they make very strange noises. I use a can of compressed air to blow out the dust, and the noises disappear. Are my PSU's fans on the verge of failure or is the dust simply making it harder for the fan to spin? I'm pretty sure it's the latter, but I see nothing against asking to be completely sure.

I would open the whole thing and give it a good cleaning, it doesn't hurt it. Should see what I do to my CPU coolers, washing them like a carwash (hairdryer included), but they're nice and clean after. No water for the fans, only moist cloth. Next going to be this old monitor, opening it up and going at it in the garage with a compressor dusting it out like new (safe, can adjust the pressure).
