Everyone's happy when the wizard walks by
If so, it should be done as a preventative step.This issue is easily solved by changing out all the thermal compound to higher quality stuff. But it's not really a job for the faint of heart, the PS3 needs to be nearly completely disassembled to complete.
My boys had a PS3 that experienced the overheat failure and they took it upon themselves to study the youtube vids on fixing/replacing the thermal compound and I was extremely impressed that they actually revived their dead PS3.
But it was short lived as it failed again within a week, this time for good.
