Question PSU buzz and slow out of nowhere

[TribalOutcaster]

My PSU went buzzing or more like it sounded as if someone is putting a finger in it's fan.

So i went to open the cover did a full clean up and check if there's anything stuck in the fan, none.

I reassembled everything back, and now the buzzing still there, except this time i had the cover open and let the computer on.

While being turned on and let the cover of the pc exposed, fair enough. I found not only the psu is buzzing but it's spinning very slow.

What is the exact specification and manufacturer of the power supply unit? Sometimes cheap or old ones going out the door are about to bite the dust and fail on you so to speak.

It may be that the fan is on some sort of thermostat which is why it's spinning slow.

Then again....there may be something wrong with it.

How does the PC function?

Also....you can check your PSU voltages with HWInfo.
They should be within 5% of +12, +5 and +3.3V.
If they are....and your PC is running OK.....you may just have a noisy PSU.

Although....I don't think I would care for a noisy PSU.....so I probably would change it.

I wouldn't put much stock into it.
With component faults such as this there is always a chance that it could be critical damage. But unfortunately the only way you're going to know is to contact the manufacturer. If its still under warranty you may be able to get a replacement.
Either way you should be able to contact cooler master support and see if they have any ideas
