Got around to working on an old original Xbox. After doing a soft mod on it the temps were running a little high so I figure I'd put in some new thermal paste. I decided to use some arctic silver 5. I was getting temps in the 60 Celsius range and started with the CPU and then GPU. Now my temps are even higher sometimes reaching 68 - 72 Celsius when idle on the dash. I tested two spread methods to spread the paste the first was spreading the paste with a card and them the rice grain method. Still getting some rather high temps. Any suggestions on to do next would be great. Perhaps I should of used some thermal pads instead?
