It varies, but u should check if the fan is still in good condition, or if there is any dust or spider web make it run slower.
Cuz when a fan is making noise, it gonna be over (my last fan did >.<) and u should check it fast, cuz if a fan is out of order, ur CPU maybe overheat and out of order too (last fan of mine was one the video card)

Well to be more honest it comes and goes every couple of days

grab a can of air ("3M Dust Cleaner" it's a can of tetrafuorethane... very cold gas that pushes air quite quickly) and clean out that fan first.
if it persists then pull the PSU and crack it open then test the fan by its self by plugging it into another PSU and running it (if you don't have another PSU to do that with then just use your current one but don't run it long without proper cooling)

if the fan is making funny sounds then just replace it. it's most likely an 80mm fan or *maybe* a 92mm (some older PSUs had 92mm fans... weird)

if you have a compressor you can use that too... just be careful not to spray directly onto the fan or any component that could break (directly on circuit boards is okay because there's nothing that'll break off

Yes, as the others have said, but dont over work this, or u may scratch the circuit board (that is not good)

you're not going to scratch any boards with just air... and if you open up your PSU you'll see that there's actually not much etched onto the board; it's mostly stuff soldered on.

There are a few possibilities:

1. A close to dying fan
2. Really dirty insides
3. Your power supply fan is temperature controlled, when it reaches a certain temperature, the fan would rev up to get rid of the extra heat, hence the higher noise levels.

only open up the psu if needed.
it will voids warranty and if you are not careful, it might be dangerous.

most of the time, it's a sign of a dying fan or just dust.

if the fan is dead you'll have to open the PSU... is this a pre-built system or one you put together? how old is it?
