I have an Antec SP500 (ATX 2.0) powersupply that has served me well for about a year and a half. I recently noticed increased noise from my computer, I thought it was my e6300's stock heatsink (which I'm replacing soon). After some investigating, I found it coming from my PSU. I took my PSU apart and found the internal inlet 80mm fan had a blown bearing that was slowing down the fan and causing annoying audible vibration sounds. Does anybody know where I can get an exact replacement for this fan? I can't seem to find one, the model number is RDH8015S and its made by Xfan (in china). If I cannot buy a replacement fan, does anybody know of a similar fan I can use?
