You may recall I'm having overheating problems with my HP Pavillion 15-N laptop. When you use tne GPU, the APU overheats after about 2 minutes.
Our bodge to Kapton tape and repaste the heat sync assembly worked for a day, then failed.
We've added thick heat transfer pads to the heat sync assembly and bent the copper shim back into shape, and added a transfer pad above the APU, as the paste was basically gone.
Now we overheat after 6 minutes, 8 minutes with a Klim extractor fan.

We're wondering if our transfer pad is too thick, so we're going to thin it out, and then try thermal paste, add some nylon nuts and screws to the empty fan screw holes (evidently there for a different model) to more securely hold down the fan, and add copper tape to the case under the GPU.
Also we're replacing the fan with a genuine one.
If all that fails, we'll downgrade to the old board.

UPDATE: Nooope. My friend Gordon and I ran it with a cooling pad and extractor, and it's running at 50Β°C APU, 42Β°C GPU under heavy GPU load. Will monitor it for an hour, but a coooling pad while gaming being mandatory isn't that weird, sadly.
I'll see if I can jury rig some more case fans by cutting ports into the baseplate when we move back in. Don't know how I'll power them tho, could drill a hole on the side and run a USB lead to the port?
@thejessiekirk I think sadly this is typical Laptop stuff, laptop chips are always designed to run a little hotter but still.
Most thermal designs of laptops are more geared towards burst loads, single core type loads like Web browsing
@ProphetsCross Aye. I think if you make a laptop with a dual GPU/APU, you should have a case that works when you use them.
I'll see what I can bodge.
