Can anyone help? Should it push air to the front or push air to the back?
Thanks in advance.
The general rule of thumb for computer fans is that the open side of the fan draws air in.
The reverse side which usually has 4 plastic arms that hold the blades/motor in place, on that side the air flows out.
So you always point the arms of the fan in the direction you want the air to flow.
That said, from looking at the schematics of the repair manual you can see that fan #7 (power fan) is pulling air out.
And fan #8 (ventilation fan) is pushing air in.
If you don't have the repair manual send me a PM and I will email you a copy.
