Hey there i recently changed my fans etc etc and now my PC is very very quiet. For example when i have a tv show or audio on its like the PC isn't there! At idle the loudest (or least quiet) component in my case may be the PSU. I am unsure about this as it is the sound of fan that is quiet but audible when the PC is idle. So... my question is, do you think the PSU is the noisiest or could it be the cumulative sound of all my fans? (6 in total including component fans). From what I can see the PSU does look a little dusty. Thanks in advance
