nope clocker would say try both ways. experiment and find the best results for yourself...they will depends on the heatsink and fan i suppose.Originally posted by jaigandhi5@10 August 2004 - 09:37
i think clocker would say blow air on it... and thts wt i wud say too try both

That's what I said as well, but with probably 80% of heatsink/fan combos they work best with the fan blowing down through the fins.
But I still say try both to make sure.

Another great venture into the goal of the 3200+
Ohh noo!!! I make dribbles!!!
I think that in most cases blowing into the sink works the best, especially if you space the fan away from the fins a bit to lessen the dead spot from the fan hub.
I keep reading posts from people who claim to have achieved better temps by reversing this setup, but their results never seem to be replicable by others with the same heatsink, so I kinda don't believe them.
It's easy enough to try both ways and see what happens though, isn't it?

My results....
My current cpu temp was 42c idle
with a reverse fan blow away from the cpu it reads at 44c idle
so i say that sucking air from the heat sink does not give u better temps
all through i would like to c it tried on another hatsink besides my SP-97
this is my first experiment in which i didnt break anything haha

First off, Idle temps are useless. To get a true reading test it under load for a few hours.
And also that little of a difference, especially checking idle temps, could be your ambient temp changing.
Check load temps.

There's a good reason why blowing air onto the heatsink should theoretically be better than sucking air away.
By blowing air onto it you are creating a positive pressure, which means that more air molecules collide with the heatsink. Sucking air away creates a negative pressure so less molecules collide. Energy (heat) is transferred during these collisions so the more collisions you have the more heat is transferred.
That's the theory at any rate, but as clocker says there are other things to consider so in the end trial and error is the order of the day.
If you are trying something which is non-standard watch those temps very carefully at first to make sure your temps aren't going way out of control.
.Political correctness is based on the principle that it's possible to pick up a turd by the clean end.
that makes alot of sence
well i tested it this time on full load and still blow air into the heatsink is better
5c was the difference
