I posted a mod guide on air redirection in my QS, but Maestro is making me question my findings.

Does anyone know which fans are intake and exhaust on the QS 2001?
I Assumed (due to feeling air at back of case) that:

60mm CPU fan is Intake.
80mm PSU fan is exhaust.
120mm case fan is exhaust.

This causes a 'low pressure zone' inside the case. Is this correct?

any help on this would be good and make me rethink my mod (if needed).
