So what your saying is that you just apply new thermal paste and expect that to be a good fix? You'll be doing that over and over again. Once you screw it all down after putting better paste on that thing is not going to overheat for a long time. It's about as close to pernament fix as you can get. I also have a modded 120g original xbox and used to be into that, but there comes a point when you gotta stop spending time and money on that stuff altogether.
