Cooling surface specs:
HeatSLInk v2.0 = 535cm2
Zalman NB47J = 245cm2
DFI stock (fan) = 62cm2
The heatSLink has over 2xtimes the cooling surface of the Zalman, I belive this makes a difference :confused: The Heatslink also have thick copper base, the other coolers are all aluminum only
M3 bolts 15mm long.. driven in from the back of the MB.. 2 very strong springs apply pressure
What did you use to attach the HeatSLink to the motherboard? It doesn't look like you reused the white push-pins.
