Rad fans CFM vs pressure?

[christoffe93]

Hi guys i was wondering if any of you know what sort of pressure levels are adequate for 240mm AIO rads? To my understanding CFM is the amount of air that can be moved and h2o is the pressure so that it can push through obstacles my question is how much pressure is enough and when does it become overkill or a waste? Obviously high cfm would be desirable if the was just enough pressure there to push high amount of air through the rad my concern is can you over shoot the amount of pressure you actually need to push through a 30mm rad as pressure is always at the sacrifice of CFM. I wantto try and find that sweet spot so that i i have just enough pressure to push through a 30mm rad so that i can maximise on cfm.

Spot on.
AIO rads are so thin pressure doesn't really matter tbo.
Any decent fan will be more than adequate.

So really i should be more concerned about the amount of air i can move through the rad as the faster i can get it through there the faster it cools giving me better temps... Right?
