Downflow / Pancake Cooler Fan Orientation for Better Cooling
I've found more often than not using the fan to pull air up from cooler give significantly lower temps than pushing air into cooler.

Reason is pushing air in through cooler means hot air coming out toward motherboard turns out, hits RAM, GPU, I/O houseings etc. turning up past cooler & fan and is sucked back into fan.

With fan pulling out of cooler air flows over motherboard, up into cooler, fan and out side vents.

Even on open bench testing just turning the fan often lowers mobo and CPU temps by 5-8c



You think I used enough pretty arrows? :tongue.gif
