Part 1
I have notice by the time that in all the CPUs heat sings , when you remove the fan after a long operation time , its visible one trail of dust on heat sing .
I noticed that the use of 60x60 fans leave the center of the CPU heat sing clear of dust.
So the conclusion is that only as small part from the heat sing receives the air flow .
I decide to experiment a bit with that phenomenon , and after of long research I end up with the idea that I have to move away the fan blades from the heat sing.
Also in my consideration was to not have any performance drop.
The solution come easily to my mind , I select one body of one fan 60x60x2,5 mm ( I had it from a dead fan) I did take off the motor and the fan blades ,by cutting the support plastics that join the motor with the rest body of the fan .
I install the empty fan body first over the heat sing and the normal active fan at the top of it ..
I will only say that my damn idea just worked , I did see a 4 Celsius drop in my temperatures .
Its possible one day the fan manufactures to start having considerations about to improves on the fans design , by the same way that the manufactures of CPU heat sings have start doing their design improves .

A = FAN SANYO DENKI 60X60X2,5mm
B = Empy FAN body
Here is the great results ,of my idea .
After of 2 months operation, the heatsing is full of dust , all of it !!!
Even the CPU clip is full of dust ,in all the length of it .
Imagine ,that the Sanyo Denki fans, have very small fan blades ,that covers only the 1/3 of the total diameter of the fun .
It looks that i did make it :) , lots of dust = good air flow !!
I guess now that i have to make more efficient dust filters :)
Part 2
Another little problem that I had come to , is one that I had create by my self , I had
add a second fan on my PSU , that was a bit help as long I had SLOT 1 based system ,as the direction of the CPU cooler was not get involve with the air that this PSU fan was sucking .
Now with the new FC PGA motherboard I had come to a problem as the my CPU fan with the PSU fan was too close .
The solution come with the idea to create one fence between the two , so this is what this pictures is showing .
A= CPU FAN
B=Empty Fan Body
C=Plastic fence
