I have a Compaq SR1630IL. I recently cleaned my CPU by removing all the air coolers and stuffs and i replaced it. But while replacing them, i didn't know the correct air circulation direction. Mine has 2 coolers, one attached above the processor and the another one to the back of the CPU case. I think i have the cooler above the processor fixed correctly; it takes air into the processor. I need to know about the one fixed to the back of the CPU case. Does it take air inside to the CPU casing or outside to the world?
