Ok, so I got the Antec Kühler 620 Problems? Well, the guy in the hardware store told me the most optimal thing is to have the fans sucking cold air through the fan and into the case. I want to modify the case a bit, so I can have the radiator on the outside instead of inside the case. Also, what is the most optimal way to have the fans? blowing through and out or as he said - into the case? The graphics card develops some heat, so he might be right and I could be wrong. Haven't done any modifications as yet, waiting for an answer from an expert (that would be one of you)..
