In one of these PS3s I did a complete cleaning of the fan area, I disassembled the radiators, left everything clean, after a few days of testing with the fan spinning fast the radiator area already had dust !!!Welcome to Sony Airline, I have the OG Phat even I Delided it,Fan at 40% 67MAX temp,I can't stand the noise like a plane taking off.
A real vacuum cleaner!
