It's the same principle here. Rule of thumb on fans: Heatsink fan blows down on the CPU/Heatsink Rear Case Fan always sucks hot air out of the case and blows it out the back. Tube-axial fans also have good pressurizing performance, and are used in blade servers. Besides the cooling performance there is also protecting the fan from higher temperatures. The fan life diminishes drastically with temperature, so why expose it to the hot air exiting the heatsink (like in the "sucking" placement? Barrel Adjuster Strategy - What's the best way to use barrel adjusters? VERY hot if you don't.
