The cooling for the CPU and chipset is more than adequate for the P8400 CPU, but would probably be a little weak for a Q9400 CPU which can be configured in this unit. As you can see in the pictures below, the graphics card cooling unit is pretty impressive however. It has large, flat heat pipes that run to a big fan and a bunch of copper fins. Under full load this cooler spins up really fast and reminds me of the Delta 38 fans from the early years of PC overclocking. . .
