This is the new cooling setup. Installed a radiator fan to PUSH air onto the motherboard. Up to now, medium heat setting on the CPU's and a system temperature of 44 degrees.

Using a 350W power supply to supply 12V to the radiator fan. It's been  running for about 30 minutes without any problems. I think I will install three more heatsink fans anyway just to keep things safe. I will not leave the power supply the way it is. I will re route the cables and the unit so that they are more pleasing to the eye.
