Hey people, I was wondering about getting copper sheets to replace the thermal pad on the memory chips of my 9600M gt, but am worried about short circuiting it. Should this be a problem?
Also wanted to know if I could do the same for the chip next to the processor (northbridge chip?).
Help is much appreciated!
P.S. Laptop is a MSI - 1651

I've done this on a desktop, works out very nicely.
You could do this on the NB as well (but only if there's a pad, otherwise you'll be hindering your cooling ability).
To do this:
- measure the dimensions of your banks of RAM (may be 2 2x1 RAM chips), try to cover groups with one piece to make it easier.
- measure your copper just a little bigger (you might have some problems coming across some copper so be aware you may have to use something else), that way, when you cut you have a little bit of leeway.
- chop it up
- put grease on the RAM chips
- put grease on the "up" side of copper piece you cut (if you cut it with tin snips or something similar, make sure the "teeth" are pointing down (or pound them flat) to make sure they don't contact the HS, reducing your cooling ability.
- put copper on RAM, move it around a little to spread the grease you put on the RAM
- put HS on, move it around to spread the grease you put on the copper shim
- close laptop up -
Thanks, I pretty much did what you're instructions said, but did not finish it due to fear of shorting something. I stumbled on one thing; the thickness of the copper sheet leaves a air gap between the sheet and the heatsink!

From my measurements, the thermal pads I replaced were about the thickness of a credit card so I had to find some sheets that were that thick as well. That's why you should have measured before purchasing your metal. Since it's too late for that, you may have to either over tighten down the HS just a little (warning: this could potentially strip the screws or mess up the holes so try to avoid overtightening) or double up your copper (this will be less effective, make sure you apply grease between all surfaces) or just buy a new sheet at the proper thickness.
If you're also willing to shave off a little bit of heat, you could also lap your HS (this may be a good thing to do if you decide to layer your copper since it will help recuperate some of the lost cooling from doubling the sheets). -
It's ok, not all is lost. The metal I cut for the gpu ram is actually thick enough for the northbridge so i just used it there. I will be getting some more metal soon.
