blowing which way

[supra33202]

I have a ThermalRight AX7 heatsink. I want to know whether I should place my fan to blow air to the heatsink or out of the heatsink. Which way perform better?

I've played with the fan direction on several systems. Blowing generally gives 1-2c lower cpu temp. Sucking generally gives 1-2c lower mobo temp. If you care more about cpu temp, make it blow.

Most heatsinks are designed to have the air blowing into the cpu. There are a few exceptions, but this is the general rule.

I've got the ThermalRight AX7 and it blows. My cpu temp also dropped 8C when I replaced AMD stock hsf or is that fhs (im not sure cus im lysdexic)
