Hi Chris,

I saw your thermal mod and it’s something I’d like to do as well if I’d buy one. I’m only wondering how hot the body gets when doing not the most CPU intensive tasks. I understand that benchmarking will put the temperatures to max, but most people won’t be doing that 24/7 :). So the Surface Pro 4’s M3 CPU doesn’t get as hot, but what about its body?

Btw, any idea when you’ll release your Cube Mix Plus review? I’m not sure yet if the higher price is worth it for me.

Sorry my previous post had typo, mailman dropped 20×20 0,5mm copper shims, Silicone heatsink paster and 0,5mm cooling pads today, just before christmas ^_^

1. Removed stock cooler and removed thermal pad
2. “Attached” copper shim on cpu with silver paste, ajusted so that it doesnt touch anything (because its bigger than CPU)
3. Put some thermal glue on stock cooler bumb
4. Screwed stock cooler back in place, waited the glue to dry out (~15mins)
5. Removed stock cooler, checked that copper shim came with it. Yes, it was glued properly and positioned properly
6. Cut and attached cooling pad to stock cooler
7. Screwed cooler back in and assembled tablet

I managed to break side of battery connector. One of the pins is exposed but it seems to stay in securely enouhg. Hope that black wire is ground, though there is no loose stuff inside anyways. I attached screenshot of XTU showings during 3D Mark 11 performance test before and after mod. It seems that my mod was successfull, there is 19C difference with peak temps. Its not long and torough test though.

After the mod, how does the casing of the tablet feel when doing things like surfing, watching video’s etc? Since I won’t be benchmarking 24/7, I don’t care about high casing temperature during that, but I would like to be able to hold the tablet without burning my hands when doing regular things.

I’d say a 1mm shim and 0.5mm thermal pad is the way to go. Apparently the thermal pad that’s in between the core and the aluminum headspreader is +/- 1mm, so you replace it with an equally sized shim. Then a 0.5mm thermal pad on top of the aluminum plate seems not to cause any pressure on the screen whatsoever. I’ve read that several people only put a 0.5mm thermal pad on the aluminum plate without any other mods.

Thansk for your reply Jason.

It’s a shame it actually isn’t allowed to open it for upgrade purposes. Which way they can see whether a tablet has been opened or not?

I haven’t decided yet where I’d potentially buy one, I saw there’s also a Cube Mix Plus with better specs but there seems to be quite a difference in price.
