Picked up a laptop yesterday for a steal, expecting it to have issues. The issues are thermal and it's nothing I've not dealt with before.
TL : DR need info on thermal pad placement particularly on the copper strip on the undertray connecting to the heat pipes top side.
The previous owner had absolutely no clue bless him about it and has tried to upgrade the laptop, bending up the chassis fitting a HDD??! His own words. The bend is there.
He's completely redone the thermal pads on it and by that I mean took it upon himself to decide he can outsmart Dell, using thermal pads from elsewhere in the machine to build a half inch tall thermal pad tower from the chipset to the plastic part of the undertray as this model doesn't come with chipset cooling. (Removed from GPU memory no less!) Aswell as adding pads to chips that don't need them, to the heat pipe some poor resistors where taking the full 105 deg C brunt of the GPU
Thermal pads are doubled up left and right.
I've found some images online and have identified that the R15 chips all need cooling as well as obviously the GPU memory and a few other bits but there's a large copper strip on the undertray to take heat from the heat pipes of which there's no photos online of thermal pad placement. I could just go ham and cover it in thermal pads.
I'f anyone has one of these laptops it would be a godsend if you could tell me the placements. Also any specs on the height of pads on the R15 chips and the GPU memory including the one that cools from the underside of the memory as Im unsure if they're making full contact and have had to double up pads to assure contact which I'd prefer not to do.
I can't test thermals till I get paste for it tomorrow, hoping I can drop from 105deg C down to 85C with correct pads, paste and an undervolt which is a bit of an ask, wish me luck!
