I had success several 3RROD fix, using Wilhelm's Improved X-Clamp Fix/replacement method.
But I had apply heat gun to isolated area, using cardboard wall arround it with MOB secure in metal casing.
Then apply thermal compound, secure heat sink with M5x10 mmx0.8 Hex nut, 2x 1mm thick metal washer ( between MOB and heat sink, 1 nylon washer on buttonof MOB and hex nut head.
Hex nut was reduced the thickness to 2/3 of it.
But I bust first MOB, cause of high temp overheating and without secure in metal casing.
MOB was become hogging and I can't recover it.
So far I had been successfully fix 25 of 3RROD.
Thanks for all persons who contribute those all of Xbox 360 knowledges.
