I couldn't help but notice the implication that a fan mounted backwards would push instead of pulling air.... It happens that that is not true. The pitch of the fan is in the same direction, forward or backward. It's just that the cupping and the blade tip shape causes the fan to not move near as much air when installed backwards. I have my fan off to get radiator repaired, so I went and checked that info.
My comments were based on non-scientific study facts, no implications were implied or intended.
Was the hood up and the shroud on when you checked the air flow?
