Power supply fan possible problems

[Keatodylan]

I am hearing a loud squealing noise that sounds like a bad fan from my pc when it is under high load, I am almost 100 percent sure it is from the psu but have no idea how to change the fan speed without putting my pc under load, is it possible to do it otherwise or should I just start say a stress test such as superposition bench on my pc and wait for the psu to heat up? I have checked my gpu fan by just ramping it up and its not from that which is the only thing close to the psu.

 

Edit: Psu is an evga 750bq

I would switch the cpu fan for another and if it still makes the noise it is the psu and I would rma it

I am 100 percent sure it is not the cpu fan so you would say it is the psu? If so I hear some people say that evga power supplies are "time bombs" should I switch to a different supply or just rma?

rma and when you can switch to a high quality one go for it
