Sounds like you have high ambients or a bad HSF mount. I replaced the stock thermal paste with MX-2 and with the fan on auto I get 85*C load in Crysis with the fan at ~72% and that's with 1.23/1.24v load. With the fan at 80 - 85% it holds temps in Crysis to ~78*C.

I'm quite certain Napalm used pencil as an experiment to identify the target resistor. Pencil mods are uncontrollable and not advisable. There is a hard mod you can do as shown, the solder point is as easy as it gets. Then you have total control.

If you absolutely must use a pencil instead, try one with a higher graphite content.
