another cause of YLOD or (atleast why the ps3 overheats)
I checked the PS3 slim too (So much for warranty) and the case was the same, the heatspreader for the RSX was not flat enough (Same symptom, only four corners are in contact with the heatsink), but the CELL is different, the heatspreader is a bit thin so I dont think Sanding it down will be a good idea. I applied AS5 this time and I'll leave it to set for a week before using it. (AS 5 setting time is 200-300 hours) (CDRKing Gold Thermal Paste Setting Time varies on viscousity but has the nearest heat transfer characteristics as AS5, good for Trial and error). Other than flatness, roughness is also a problem. $ony decided to use Copper Heat spreaders and coat them with some type of alloy to allow etching the labels and prevent corrosion. Nevertheless, it's time to go linish your units, especially if your beyond your warranty period. Replacing the thermal compound will not do the job, time for a permanent fix!
