We found that water cooling has to be used with air cooling for good results, kinda defeats the object a little I guess..

There are 2 other issues too,

1) The Fusion block is spot epoxied to the NB heatsink, there is poor contact between the 2 surfaces, no thermal paste is used by Asus to fill the gaps this bonding process leaves behind. Our block came off, and we reattached it using thermal paste and epoxy. Thermal paste in the middle, with a good quality epoxy glue around the perimeter of the block to hold it in place, it is now rock solid.

2) The supplied thermal pad interface between the chipset IHS and the heatsink often make poor contact, we had around 60% contact, with no contact in the middle. Replaced with good TIM.

Loaded temps during Prime95 Torture Temp @ 460 FSB were around 39 degrees @1.65VNB and 2x 120mm fans. Before the above 'mods', loaded temps were around 49 degrees.


Review should be up on Anandtech in couple of days..
