[SOLVED] Corsair TX750M - fan always at full speed

[rabbitcfh]

Hello. I'm having an issue with a brand new Corsair TX750M PSU.

I've just built my new PC and almost everything works fine, except for the PSU. As I boot up my PC, all is well but as soon as I start gaming, the PSU fan goes to full speed - and even when the PC goes back to idle, the PSU fan keeps spinning at full speed with the sound of a jet engine until I restart or shut down the PC.

Is it likely a faulty model and I need to return it, or did I do something wrong during installation and is there any way I can fix it?

Thanks in advance!

Can you list the specs to your system that the PSU is powering? If the PSU is being taxed to it's limits then the fan is trying to cool the unit as best as it can...or there's dust/debris build up that is impeding the cooling of the innards of the PSU(the components that help smooth out the power output).

How old is the PSU?

It's a brand new PSU - I installed it today, and it's all clean inside my case.

My specs are (everything is new, except for the GPU and the drives, which I moved from my previous build):

MSI B450 Tomahawk Max
Ryzen 3600XT
Patriot Viper RGB 2x16 GB 3200MHz
GeForce GTX 1060 6GB
2xSSD, 1 HDD

I checked my CPU and GPU temps earlier and they were all low (CPU in 40s, the GPU also pretty low. A little bit higher during gaming but still low. There's also cool air coming out of the case and no hot air coming down from the PSU so it doesn't seem like the PC is running hot).

I ordered a new one (same model) and it works perfectly fine so it seems the other one must have been faulty, a broken temp sensor maybe?
