I recently bought a new computer, and replaced the power supply and GPU from my old computer. Occasionally when I start the computer, the fan in the power supply makes A LOT of noise. This doesn't happen all the time, but often enough to be annoying. I know it isn't the power supply itself, because it didn't make any noise in my old computer. It eventually stops making noise after about 10-20 minutes.

I've already tried making sure it is fully secured, with no luck. Help!

Manufacturer and model of your power supply? And also post list of your other components too. If your power supply has bottom/top mounted fan is the power supply placed the way it could pull air easily inside or is the fan side against case wall which has no holes in it?

I don't know the manufacturer of the power supply, unfortunately. I got rid of the box a long time ago to save space. However, the fan opening is facing the back of the computer, and there is a hole in the case to allow airflow.
