CPU Heatsink :~

Ok, I haven't got it yet so I am not sure but I will keep what you say in mind, thanks. I was just going by one of the reviews that said, "Antec recommends that you install the fan between the radiator and the case so that case air is sucked through the radiator and expelled from the rear of the case". It should be a simple matter to try fan both ways to see which gives best results.

My PSU actually works the way you suggest although it originally belonged to another case and I have a feeling it sucked air in through the back and blew it out through a vent in the top so I have installed it upside down! As part of sorting out the cooling I was going to open it and flip the fan over.
