top one is right. You want one fan blowing air in, and the other blowing it out the other end.

Example 1 is how you should be doing it.
post #4 of 22
First example, you want one pushing air in, then the other pulling that air out.
# 2 will create a vacuum inside which can't get any air
# 3 will force air in, but no air will be moving inside.

The first one.

You see, "push" means the fan is pushing air through the heatsink. "Pull" means there's another fan pulling air away from it.

So we could almost also call it "intake/exhaust" (that is, to borrow case fan terminology).

The purpose is to maximize the heat dissipation by adding a "pull" fan.

I need to elaborate a little:

Example 2 is pull/pull.

Example 3 is push/push.

Only example 1 is effective.
