On a PC, it is difficult to do.

Basically what you want is straight shot airflow, ideally speaking.

If you can't get that, at least try to go front-back, and avoid too much
internal turbulence.  That's a PCs big problem.  A lot of the air inside
is turbulent, which reduces cooling effectiveness, and traps a lot of
heat in little pockets here and there.

Positive case pressure can help here, depending on your case and where
vents are.
