Just got the ACF7P yesterday, and had time today to install the fans.
Back of case
Took out the pci slots on the back to let the hot air get out(Not sure if this works or not, just using my dumb brain of mine
Stock fan connector got removed because New HSF is too big
The new 80mm fan
The other new 80mm fan(see that wire running to the bottom right?)
Everything installed and put back together
Going to try and overclock it some more see what happens.
