I hope this info will help. The fan selection doesn't sound bad but there is some things that you might want to try. First of all the air flow should be in at the front of the lower front of the case and out the upper rear of case. I think that your side fan should be blowing in. (it will help keep your video card cool.) Beleve it or not but all the reading that I have done as said you should have a zero to a SLIGHTLY minus pressure in the case. You can do the math for your self using the fans that you buy as far as CFM. Good luck. Take care. Oh yea, I almost forgot. Try to keep any air turbulance arount the HS and fan to a minumum. I have seen HS set ups with a scoop facing forward to prevent this from happining. I made my own scoop. (it wasnt pretty but it worked) The scoop did drop the CPU temp. Good luck again.
