I have 4 fans in the bottom front sucking in air, which also cools the HDD's, and 2 fans in the back supposedly blowing air out but I reversed them. That makes 6 intakes and 1 outlet(PSU).

6 case fans, a Volcano7+ HS&F, the PSU's and the stock P4 cooling fan cooling my graphics card(Taken out due to no improvements in overclocking my GF2MX, will be put back in when the 9500Pro is available.), totalling 9(8) fans.
