Please bare with me while i try to explain this.
We all know that the most important things with a HSF are:
1) The velocity of the air coming out of the fan onto the HS
2) The difference between the temperature of the air being pulled throught the fans and the temperature of the HS itself.
Well, almost all HSF's have the fan positioned directly ontop of the HS .... this sounds like a good idea but due to the actual motor on the fan there is a dead spot of air directly in the center of the fan. If that makes sence.
So therefore the center of the fan does not create a high air velocity and there is less difference between the air temperatures. Now on a CPU which area is the hottest?? Its the Core which is in the middle of the chip and therefore in the middle of the HSF which is getting far less fast moving cold air being blown onto it ......... This to me sounds stupid.
So what can you do ???
Well if you raise the fan above the HS anout 1-2 inches the dead spot will have dissapeared by the time it reaches the HS as the walls of air which are blown from the fan willspread out and bring air in from the sides, sort of covering up the dead spot.
Does this make sence ????
