Discussion Case airflow & thermal discussion

[pipbug]

Positive (pulling fresh air in) airflow vs negative (pushing hot air out) airflow in a portable? Best heatsink configuration, thermal compound, etc? Noise & heat is a concern to some people when making a portable; what do you go about doing personally? Do you care much? Discuss

Depends on how hot the system gets. If it doesn't get very hot, positive pressure would probably be better, but if it gets kinda hot you don't want hot air blowing out of any cracks there may be in the casing

Suck air in in one vent, exhaust it out the other.

Just a single fan I'd reckon? I'll probably be using a single PS2 Slim fan as an intake to cool my portable, with an exhaust vent or two.

Yep. The Wii only needs a single fan.
