Had this power supply for about half a year now and never had this problem until now. The case has a filter for the PSU so I doubt anything is blocking the fan, and I actually just got done cleaning the my entire computer including the power supply. That seemed to have stopped the sound for a while but an 1 hour later it came back. Anyone know what is causing it? Any fixes?

This happens when the computer is idle too. This problem is a come and go it'll start making the sound randomly not even playing a very high demanding game will cause it, it just happens randomly.
