M6800 Heatsink mod idea......

Printer Accessories & Printer Consumables Forum - forum.printercomparison.com
After overclocking the CPU on my Dell Precision M6800 ( see here how I did it: ), now I am considering to improve the heat transfer, as that is a major bottleneck.I've been analyzing the shape of my CPU Heatplate and heatsink and I really don't see a good way of adding an extra heatsink to it (but I would welcome any idea).

That one is made of copper, so if there would be a way to separate it from the heatpipes and take it off, I could replace it with a SILVER plate. it wouldn't be very cheap, but it wouldn't break the bank either (approx £15 for a piece of silver 30x30x2mm).Silver has much better heat transfer than copper, so I assume this would greatly increase the efficiency of heat collection from the CPU (in theory with almost 10% compared to copper).

I was thinking to use low-temperature solder (i found solder that melts at 139°C, which I think would be okay, as a heatpipe should be safe to operate up to around 180°C - 200°C).
