PS3 YLOD

Figured might be someone inhere played with this before, my nephew croaked this week and did little digging about the net, curious if anyone had suggestion on this repair or suggested route of those that have revived something along this failure,
I’ve yet to start the tear down but looking at replacing the thermal compound and lot of the people wrap it up in aluminium foil and bake them for few minutes in a oven , with the cpu exposed to help reflow any bad connection , A does it actually work or someone else have better suggestion >=)

Thanks ahead time,
