Yes you did replace compounds but WHAT compounds have you used ? currently I would NOT recommend to use good branded liquid metal comes with no pump out effect but it req. good skills and is bit dangerous on CPU specially direct on 1-st stage CPU second is alloy which is not that good with liquid metals (CPU is 2 stage construction) and it's CONDUCTS electricity you have to be VERY EXTRA CAREFUL.
All tests showing that you have NT-H1 it's hybrid compound best of both worlds I would recommend to use as in all tests in all pages i was browsing was after liquid metal compounds and difference in all ranges CPU power usage was about 1*C , just do NOT over do it as if you use to MUCH compound efficiency of thermal transfer drastically drops !!
not really, I did replace the compunds both beneath IHS and above IHS, there are little changes on temperatures after i replaced it, although on 2c difference, so I cant see anything wrong with it until this FCU came, now my PS3 is cool like 51celcius and 48celcius after I set it to 0xC5, kinda loud fan noise but I dont care since I play with headphones, also its better to get the fan wrecked than having a YLOD PS3 which is much more expensive than replacing a new fan.
