Np2096 Heating Issue. Thermal Comp help?

A Sager NP2096
~4 (almost 5) years old
Insane temperature hikes/eventual shutdown.

With this computer i used to be able to play all my games, even with teh computer on my lap with no heating issues at all. I've had it for almost 5 years now and now it heats up even while raised up off of a hard surface to 90+degrees playing even simple games (CSS). With a laptop fan it plays games at ~85-90C which causes obvious FPS drops and choppy game-play. I've cleaned it out regularly to keep it free of dust and all vents are completely open but i've never replaced the CPU/GPU thermal Compound. (it came with Arctic Silver thermal compound) could my issue be resolved via re-applying new TC?

Here are some temp readings

After computer has been off for the entire night I start it up and let it idle for 5 minutes


I Launch CSS at 1600x1050 and let it sit at the main menu for 8 minutes


I actually connect to a game and play CSS for 10 minutes


At this point in time the game drops from its normal 100+ FPS to 30 and below and starts getting choppy as hell.


Is this a GPU problem or just a old TC problem?

If TC will help are there any detailed instructions to take apart this np2096?
I've looked at the Users manual but the pictures are missing half the thats in mine.

Any help would be greatly appreciated.

 

Nobody?
should i post this in Hardware?

 

Most definitely it could be solved.

I recently bought some Chill Factor 3 (no IC diamond 7 available here) and it worked wonders on an old IBM R51 when I cleaned out the fan and repasted it.
