I’ve got a hypervisor box with an AMD FX 6300 in it. I used a 400w Cooler Master PSU (fairly old but unused up to about 6 years ago when I built the PC) that I had around and it has worked fine, and still works fine. But the fan bearings are going bad. I’m confident I could just buy a fan and replace the fan, but since it’s a power supply I’m not sure that’s a good idea. If it’s been in operation for so long that the fan bearings are bad, is it highly likely more important parts are going to die soon? I don’t want to replace something that’s still good but I don’t want to kill my motherboard/cpu because I was too cheap to buy a $40 new PSU.
TL:DR; Mediocre cooler master PSU is about 6 years old and works fine but fan bearings are going bad. Is it stupid/futile to replace the fan and keep using it after all that time? Is there a high likelyhood the PSU will kill my mobo/cpu soon with its age?
