What was wrong with it in the end?
Doesn't look complicated at all, nothing compared to a proper PC.
Similar issue to the XBOX clamp issue and dry solder joints to be honest.
Reflow/heat the CPU, GPU and new heatsink compound.
Its a bit of a git to get down to that level though but theres fcuk on the main board as you can see. Quite interesting really for a geek like me
I have had my fan sound like a jet a few times Gally but touchwood its still going.
Sony wouldnt touch his one apparently, (according to him), they wanted £70 just to try and fix it...I will charge him a few beers/ £10
Like I say touchwood that the "repair" lasts...just have to wait and see really.
