Question PSU fan vibrating sometimes on high load by slowing. Nothing wierd with performance

[Emkot]

My power supply is a coolermaster rs-600-acab-m4 I've had for about 5 years and has made some vibration on and off but nothing as loud as recently and as annoying. It seems to be doing it at random but has a much higher chance when the PC is at load. I will provide a void video showing the psu fan in action. Is it fault of the psu ? Will it be resolved by changing the fan? Is it possible to change the fan with an off the shelf one ? Thanks to anyone who answers!

Replace the PSU

Replace the PSU

It actually stopped vibrating and is back to normal should I still replace it ?

I would still replace it if you didn't do anything to fix it. Hardware problems like that which magically disappear could just as easily re-appear at any time.
