No, you want the rad cooled with "fresh" air, therefore blow into the case.

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.

Ehem, sorry Swiss, which fan do you mean should blow air into the case?

Rad=radiator.
Rad has to be cooled with outside-case air, given the rad is located inside the case you will blow warm(through the rad)air into the case - unless the rad is completely outside the case.
Getting hot air out of case is the job of the other fan(s).

I use partially warmed air drawn through the radiator and out into the room. It keeps my over-clocked Phenom 975(4GHz) @ 33 to 38C. Using cooler air, it would run 32 - 37C. Not a lot of difference there.

Made a huge difference in this test.
