The way to answer that question is to ask yourself: when you are overheating, your sweaty skin are the fins of your heatsink, and which way do you want a fan pointed then?onlysublime wrote:sorry for the n00b question, but is the CPU fan pushing cooler air onto the hot heatsink to cool off the CPU or is it pulling the heat coming off heatsink to cool it down?

If you do this a lot and can spend a little money, I'd recommend an aftermarket fan/heatsink combo. Noctua for example has some great designs, and if any of them are compatible with your system they stand a good chance to cool your CPU a lot better.

Noctua are awesome - they're not the cheapest, nor the most efficient but they ARE quiet and when you upgrade to a new motherboard socket in the future, they'll give you the new mounting hardware for free.
My advice would be to lay the PC down so that the heatsink is vertical if you're driving it anywhere by car. It's probably not necessary, but you don't want to have to find out the hard way.

I don't remember about the front fan so I'll have to get one of those as well. So I guess I'm in the market for 3 case fans...
