PSU fan is failing. Replacement essential?

[bcomatts]

My 3.5 year old PSU's fan is failing. On a regular basis the fan stops, I can restart it by simply tapping the back of my computer.

I am just wondering if having no fan for a few hours before I realize it's not spinning and fix it, is that ok?

I notice on my water cooling that the CPU goes from a regular 27 C/82 F to 34 C/93 F when the fan stops.

Thanks for the read.

is there any dust back there? have you tried blowing it out? I don't think I would let it run w/o the fan running. As cheap as PSU's go, letting one just die on you and risking catastrophic failure just seems like a bad idea to me.

It's not the temperature of the CPU that's a concern in this case, it's the temperature in the PSU itself. If it heats up to far it will shut off or fail completely. I'd replace it.

Yeah, I would replace the PSU, or I would buy another fan, if the PSU is pretty nice, and I would install that fan and just hardwire it in to the stock specs

It's not recommended that you open the PSU and replace the fan. Lots of things in there that retain their voltages for quite a while... But yes, if your fan's failing, you definetly should do something.

Replace it.
