This may sound like a simple question but I just purchased a Thermalright Ultra-120 (actually my friend bought it for me for helping him build a new PC) and I would like to install it in my Antec P180 case. There is not much room behind my PC case as it is against the wall so I am not sure what would be the best way for me to position the fan. Since there is no power supply above the motherboard, my idea was to have the fan blowing from the bottom of the case through the fins to the top of the case so that it can escape through the top vent on the P180 case. Does this sound like the best idea? Thank you in advance.
