Due to the fact that this PS3 has been reflowed many times before, The top CPU attached heatsink needs to be removed and replaced. Basically it needs a new PS chip. What we see is a common problem with the loud fan after multiple repairs. A new chip install requires reballing. It is neither a fan or heatsink issue, rather there is a secondary layer on the microchip that needs to be removed and replaced, removal of that layer damages the chip and therefore we only replace the chip. We have tested for about an hour of play time and we have gotten the over heating messages.
