In the next few hours I'm going to be using this heatsink and fan, want to know what would probably work best: having the fan suck hot air from the heatsink, or blow cool air onto it.

Here's the case setup: 2 80mm intake fans in front, 1 80mm intake fan on side, 1 120mm exhaust fan on back, plus Antec True430 PSU.

Blowing onto

My XP-120 + Panaflo works best in exhaust. YMMV, I suggest you try multiple configurations and see what's best.

Thermalright suggests blowing onto the heatsink but I would suggest trying both.

[SilverJag]

Definately try both.

Sucking if you have a duct to the outside, blowing if you don't.

[Thanatos_2005]

are you using a 92mm Panaflow? if so I have the exact same setup and blowing works the best, barring, as previously mentioned, any extra case mods like a heat duct, etc.

I have the same setup but with a Delta . Works great for me. But may not for you. Like everyone else said try it both ways and see which is right for you.

Ok, once I finalize my setup (using a 3.06 instead of a 2.4 right now) I'll try both ways, shouldn't be too much of a problem.
