There is an odd "revving" noise coming from my XPS8300.

I believe that this is the power-supply fan.

I have airdusted and cleaned all the fans, however the noise is still there.

It's not constant, it comes and goes, lasting from a couple of seconds to minutes and it has nothing to do with CPU usage. For example sometimes I'm not even using it and it will still make that noise.

I have had this problem before, maybe a year ago and it went away by itself however now it returned and it won't go away no matter what I do.


Please advise, should I be replacing the fan? or the PSU?

Update: I have recorded the noise: http://picosong.com/knwP/
Hopefully someone will recognize it.

you can replace the fan if you are able to.

Updated my first post since I recorded the noise...it happens every 10 minutes or so.
