The aluminum base supports the heat pipes and presses them against the CPU heat spreader. Increasing the thermal conduction to the aluminum base plate may actually reduce how well the heat pipes transfer heat to the fins??? Only testing would tell.

actually... you CAN. it's just not called soldering. He'll be doing something called "Brazing". http://www.youtube.com/watch?v=62t61RZ37Bo

OP - Last time I looked (recently) silver solder was 3% silver. Not exactly world-burning in the heat transmission dept. Does your solder have specs on heat transmissivity?

Thread Starter 
actually the solder I have in mind is jewelers silver solder its more along the lines of 95% pure.

and provided i dont ruin it a small torch would work fine for melting it down in between the 2 and bonding them.

Just make sure you choose the right type of flux, otherwise the metal won't flow properly.
