push pull cpu

Hi all

I have 2 spare fans one is rated 90cfm and the other 50cfm which way round should they be mounted make any diff? was thinking 90 pushing and 50 pulling

Just on a old amd rig just going to have a bench see what she can do.

Id expect the 90 to do better by itself, but id be interested if you test various combinations

to me theirs logical reasons for both ways round which testing would have to decide.
