Default Power supply fan (which way it blow)?

I had to reinstall the fan in an old dell PSU and I forgot whether the fans blow into the PSU or out of the PSU?

Hello,

Originally, the fan expels air out from the PSU.

If it's a fan facing down, at the components, inside the tower, if should be blowing air into the PSU. If it's the fan, at the back of the tower, facing outside, than it should be taking air out from the PSU.
