I've noticed some people put their fans below the radiator and others put their fans above the radiator. Can anyone explain this difference to me and the benefits of both? I personally put my fans below the radiator for a top mount, then I stumbled across a video w/ someone having their fans above. I'm not sure if I should switch locations or let it be?
 
Solution
There is no real world difference either way you do it. For me is all about the look. I like to have my fans on the bottom so that I can see them. But if you have plain jane fans, you may want to hide them up top.

I prefer to have mine pull the air through the radiator. It makes cleaning dust off the radiator a lot easier, since you don't have to remove the fans. If you have a push configuration, you will need to remove the fans in order to clean the dust from the radiator.
