PC power supply making a lot of noise upon startup...

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.

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

The fan is still brand new. I highly doubt I need to replace it. Like I said, it worked fine in my previous computer.
