Zalman 7000s

[Zucarita9000]

In wich direction do the fans in these coolers blow air to? Into the heatsink or out of it? I'm building my system as I write this, and I have the following setup:

Antec SmarPower dual-fan PSU. The 92mm intake fan takes hot air out from the CPU.
A 120mm Panaflo L1A fan, also pulling the hot air out of the case.
Zalman 7000B Al-Cu. If the fan is blowing into the heatsink, and with two fans taking air out from basically the same place (CPU area), wouldn't I be having some sort of vacuum or negative air pressure going on in there?

There would be three different directions for the air to go to. (out of the case trough the PSU, out of the case through the Panaflo and into de heatsink through the Zalman fan).

If the Zalman blows out, then the hot air would be taken out very quickly (Panaflo+PSU).

The air is forced down through the heatsink, you can tell by looking at the blades on the fan.

It's an "innie."

Or you could install an air intake duct so your 7000s pumps fresh air from the outside. I have one off these with an intake duct and my 3.0 Prescott never passes 55C (Prime95 TT) in brazilian ambient temps (~30C) ;-)
