Negative or Positive case pressure?

[Hamish]

Hi!

I have a gaming PC in a CM Storm Enforcer case with standard fans. I am adding a top fan for extra cooling, and was wondering if it would be better for temps to have it as exhaust or intake

Current Fans
Intake- 200mm 1000RPM
Exhaust- 120mm 1500 RPM
Exhaust- PSU fan
Top fan- 200mm with 192 CFM air flow.

ANy recommendations?

Intake, unless the air is moving up to begin with.
