Quick Radiator Question

[speedbird744]

Guys,

When mounting the fans onto a water colling radiator, should the fans be blowing onto the radiator, or away from it?

Sorry for such a newbie question...

Usually they blow away...

From what I have seen they are almost the same with it being a little better drawing through the rad for both temps and noise.

Here is a table of what PH of ProCooling got when testing fan direction and the effect of shrouds.

In my setup, I use two (2) dual 120mm rads and each employs four 120mm fans - two to each side so that the air is moved in a "push-pull" configuration.

I have heard that you might get slightly better performance by using a pull configuration (Fans blowing away). But its only very slight, and you get better with push/pull
