But I thought....?

That you get better results with the HS fan sucking away from the HS, mny buddy turned his 7krpm Delta around - and it drop-ed 5c blowing on the HS.

Meaning that the fan is blowing on the HS, and now its 5c lower.

I am thinking of doing the same with my Glaciator Fan it it will shave a few idle/load degrees?

What do u guys think,

[Random Nonsense]

it is all down to case ventilation... around the socket you have lots of resistors and capacitors... these heat the air being sucked into the HSF.... if you can keep this area cool then a fan blowing OUT of the HSF should produce cooler temps as the centre of the heatsink above the die is getting cool air over it... when blown in most ppl with poor cooling of surrounding area get cooler temps, but the very centre of HS is often in a dead
zone.

nope, most fans are better blowing, this is because it can batter the bottem of the heatsink with cold air, when the fan is sucking it takes air from the top, leaving the bottem to warm up, the only time you should have a fan sucking is if it has a skirt that forces air to come in at the bottem, only advantages of sucking it the noise level drops

It depends on the design of the hsf more than anything. The Glaciator was designed around airflow, so I would say that flipping that sucker around wouldn't be the best idea.

Does your friend have a fan right over his hsf? Maybe sucking air away from it? If so, then flipping the fan on the hs helped a lot, because the two fans weren't fighting for air anymore. :)
