Neither. It just blows air out of the case.

The fans reccmmended/used here have the same airflow.

There was a guy here who swapped the fan then didn't notice that the new one wasn't spinning. He was impressed by how silent it was. The 'scope worked fine.

The 'scope is rated for a 50 degree environment so even if the temperature goes up a couple of degrees you'll be OK.

klausES:
Although the fan sits close to the power supply and promotes them primarily through this,
but his flow rate is, of course, the amount of air, which forcibly flows through the (entire) housing.

Do not have to flow, because completely without air stream, there were not only in the power supply,
but also on the motherboard some hotspots, which would achieve questionable temperatures without moving air within the housing.

NEDM64:
Yes, if the fan doesn't remove the hot air from the PSU, then that air will heat the motherboard.

Also mind that the hotter the device works, the less it will last.

Fungus:
We're not removing the fan or blocking it, just putting in a different one.

I have already understood.

I only raised the objection because this one sentence (someone has exchanged the fan and not noticed that this did not ran ...)
someone could suggest someone that it could go without throughput.

The CPU has already on its outside with sufficient air throughput quite fast over 140 °F.
Have noticed with my tests with the fan control that the outlet temperature "out of the housing" can increase
at a to low-chosen flow rate (of course not by the CPU alone) after half an hour to 100 °F, in summer to over 115 °F.
