I followed these instructions, adapted slightly for my 3rd generation ps3. Unfortunately I ripped out the fan connection while trying to disconnect and ended up having to solder the connection. (I had a soldering iron but this was actually my first soldering project-- whew.) I think the soldering worked (I heard the fan start-- much quieter now) but sadly the YLOD greeted me once again. Did I mess up the thermal paste? I think I used too much because I ran out. I guess this is worth a final shot once I acquire some more thermal paste.
