Its fins are bent to blow air onto the components in the case. I know the heatpipes do the majority of the work, but the weight 656grams and the max air pressure of 0.052 inch/h20 have me concerned a bit. It is ASUS so I am sure it is not junk. They said it was not a standard fan(SMALLER) I WANTED TO PUT A TRICOOL ANTEC IN THERE, BUT I GUESS NOT.
I have been looking at this, the Zalman CNPS9500 AT $49.99. EVERYBODY KNOWS ABOUT IT - A legend in its own time.
The fans on both of these seem a little weak at approx 35cfm
Wow that is big. Well everyone here is always talking about the Scythe Ninja which has now been discontinued. The Scythe Infinity appears to be it's successor. But if you're hesitant about the 656 grams of the ASUS Square then the 960 grams of the Scythe Infinity will downright shock you. Even everyone's old favorite, the Ninja was only 665 grams.
Seriously thought about the water thing but what about cooling the other components(VRM). The other questionis how much cooling is really needed for a moderate overclock of a C2D about 3Ghz. Do I even need another HSF. I will be using the ASUS P5wdg2-ws Pro in an Antec P180 case.
In just looking there might not be enough clearance for a big HSF. The cpu is pretty close to the edge.
