Dv9000 nvidia 7600

Hello, I want to cool of the gpu, cpu, north bridge in my dv9000.I have read to install copper shims. Could someone please tell me the best size shims to use. Lenght width and thickness. Maybe a link if possible. I want to do my best to cool all 3 components. If there is something better than copper that would work too. Thank you.

 

The copper shims are all over ebay I chose the .055 mm shims and stacked them on the GPU I have the 6150 but will work with any GPU as well as the Northbridge . My board has no Northbridge but the idea is the same. Plus drilling small holes under the heat sink helps in cooling just take some heavy paper and mark out a grid 10 x 4 cm with the holes about 1cm apart and made 3/16th" holes. start with the smallest or 2nd smallest bit you have to drill pilot holes going from inside the case. The pilot holes will keep you from cracking your case, !!!!!drill slowly!!!!! This copper shim mod kicks. I've tried everything to get my machine hot and the only thing that remotely warms it up is bruteforceing passwords @ 100% cpu usage for 77 hrs straight and temps still stayed under 80c. Btw use the best thermal paste you can get. All the top of the line pastes are comperable as far as heat conduction, I used mx4 because it is non-conductive electricaly . Good luck.
