I understand that part, but my question is does the stock fan do better PULLING out the exhaust or PUSHING out the exhaust
Exhausting from the case is only one way. Fans blowing in are Intake. Fans blowing out are Exhaust.
Just make sure your fans are both pointing the same direction otherwise the air stays in the vanes and the cooler doesn't cool your CPU. I accidentally faced both my fans in on each other when I replaced the High Speed Silents with Medium Speed Silents. Didn't take long for me to notice there was a problem.
My Idle temp is ~31-34c and my Current temp while Folding having 11 Safari tabs open and playing ACII (This I'm sure qualifies as full load ) is 39c no AC, or Window open. Of course my CPU is lapped. But that gives me 10-15c drop in stock temps.
