Asus P5K-Pro users warning !

Just a word of warning for P5K_Pro users. Because of the pressure applied on the cpu by the cooler (including box-cooler) and the lack of a backside retainer, the PCB starts to bend. The biggest problem is with the MOSFET cooling heatsinks. The deformed shape of the board makes the heatsinks have contact with only 2-3 MOSFTES near the the retainer clips instead of all 12.
The same thing happens to both heatsinks.

To fix the problem i have attached some adhesive rubber pads on the backside of the pcb just on the middle of the heatsink. When the motherboard goes back int-o the case it's beeing forced to keep a normal shape, thus all MOSFTES making contact. I also removed the thermal pads and put some silver based thermal paste.

I'm sorry that i took only one picture:

Another note, some normal stuff. The chipset heatsink has a plastic like thermal interface. The temperature got pretty high, cleaning the thermal plastic goo or whatever and adding some silver based thermal paste took the chipset with the original heatsink and a small 40 mm fan to a few degrees over room temperature from scorching 60+ degrees.

PS: the "cooper looking" heatsinks are made out of anodized aluminum, and have a lousy finish, You can fit a fine flat screwdriver between the machining marks. If someone have the patience to lap them till bare aluminum the efficiency will be even higher.
