I have a launch model PS3 i got for a bargain because the owner said it overheated every 3 min. He was right so i decided to replace the TIM underneath the RSX and CELL heatspreaders. This model also has a 3rd heatspreader on the CXD2973GB chip which i think is some kind of AV decoder or south bridge. How hot does this chip get and does it also have TIM underneath that should be replaced? Can it be removed the same way as the CELL heatspreader? Any input would be much appreciated.
