thanks everybody for all your quick and useful answers ;-) (as always on the gentoo forum. that's (another) reason why I'm fond of gentoo). I've seen pictures of water-cooled boxes and that sort of things. I'just want to have a quiet and normal heated PC. No need to do supra-conduction at 3°K. When I talk about "wrong-sided" fan, I meant the cpu cooler. I've turned it around. But the temp is still the same (67°C now). My case is an enermax and it's true that I've a lot of IDE cables around. So what do I do now? My main goal is to have a quiet PC. My TV is in the same room. I want to be able to hear tv while make modules-ing, make bzImage-ing and emerge world-ing. I don't have any case fan and after all your answers I guess that the first thing I should do is buy one and use it to pull air inside.
