Indeed!
Side fan should be an intake
Rear fan should be an exhaust (120mm

).
Front fan is intake : that's ok
CPU fan should blow air to the rear exhaust fan : so you have to hook up the fan on the other side
So relatively cool air will flow through front and side panels and hot air will blow away from rear exhaust fan and from the PSU back grill
Anyway idle temps are pretty high. The casing is too small for such a high-end system..
set the VGA fan to 100% using EVGA Precision. CPU is around 50-60 under load or idle?
