M-Series (M-6862) GPU Overheating!

I've been searching this forum for days and haven't found exactly what I'm looking for. I bought this laptop used off eBay and it was running a little hot for my liking, so I took off the heatsink, scraped off whatever gunk came stock, and applied some AS5. I also undervolted the CPU (my 12x went all the way to 1.0975 before any errors!). The CPU idles in the 30s-40s and tops out around 70 with Orthos. Very happy.

The problem is the GPU. I downloaded Crysis and almost instantly after running it the fans kicked up full speed. I played a few minutes before exiting and my Tmax was 109!! Something obviously isn't right.

*EDIT
Alright, I was dumb. The orange film I was thinking about removing was surrounding, not covering, the area that makes contact with the heatsink. That's what I get for rushing. I took everything apart last night and really scrubbed everything clean. Reapplied AS5 using the tinting method from their website, and after two minutes of FUR stability testing my GPU's at 95 instead of 101 within seconds. The GPU isn't make great contact, and the northbridge doesn't seem to be making any contact.

I'm going to be trying something like this out. I'm on the right track now, so feel free to delete this thread.

 

I have that very laptop. I recommend using thermal pads to provide the contact between the heatsink/GPU. That is how they originally shipped (with the thermal pad).

Also see here for a quick easy/safe mod:

I hear that with IC Diamond 7 you don't need a thermal pad. But if you already have other thermal paste then go with the thermal pad.

 

IC Diamond 7... It is thicker then some pastes but I wouldn't recommend just using that. There is no contact between the heatsink/the gpu chip. Thermal pad or metal shimming would be the better alternative.

 

Thanks for the responses! I had noticed the same thing - the filter keeps dust out, but also keeps air out lol. The only thing that's stopped from cutting the filter out is I'm worried about the internal parts being directly exposed. Do you think this would be a problem?

The pads are starting to sound like the way to go. The copper mod I linked to seems like a good idea, but I don't know where to find copper, don't have the tools to cut it, and don't like the idea of free copper being inside by laptop that I carry around. A poster further in thread linked to this company called Chomerics that makes this thermal gap filler that I just ordered a sample of for free.
