so i got an iMac that someone gave me, and sometimes it makes weird crackling noises they seem to be coming from inside of it, and it does them only when powered on, it's not that loud and it seems to be coming from behind the screen mostly where the psu is located, but i'm not sure...
§the mac works perfectly though, no flickers, no sudden shutdowns, no weird smells, i heard that it could be an audio issue, also that a capacitor on the psu can be failing and cause the problem, as of the location of the crackling noises the psu is the most likely thing.

but will i have problems in the future if i keep using it like it dying on me randomly? i had a 2006 psu explode on me once and i don't want it to happen again, i do have a psu from a 2009 imac of the same size, last time i tested it it worked, so could it be safe to use that one in case the current one dies? and if it dies will it damage other parts of the system or just the iMac?
