The only heatsink in this laptop is this big metal plate. In most laptops, a fan or two blow directly through a stacked-fin heatsink in a process called forced convection cooling. In the X Pro, heat spreads across the metal plate with the heatpipes’ help, warming up the air inside the laptop. The small fan exhausts all this hot air and brings in new cool air using negative air pressure. It also generates some, but not enough, airflow across the heatsink plate.
The miserably small fan can spin at nearly 9,000 RPM, but the bar under it (where a heatsink with fins would usually be) is just one of the WiFi antennas.
The fan is the model BAZA0504R5H made by Asia Vital Components and rated at 5V 0.5A. This means it could theoretically use 2.5W when spinning at max speed (which happens to be around 8800RPM).
Look at how thin the fan is!
The fan has a sealed bearing.
The fan motor is 3-phase with 6 poles.
The copper base plate for the CPU.
Behind the keyboard is a pyrolytic graphite sheet to spread heat more evenly across the keyboard area.
See the motherboard with the heatsink off. The Nvidia MX150 GPU gets a thermal pad as if it were an Intel iGPU.
The back of the motherboard is covered with a plastic insulator film.
This is the motherboard’s back with the plastic film removed.
The Nvidia MX150 (1D12 10W version) and its VRAM.
The motherboard has good component density. It’s also the thinnest I’ve seen. The coil whine is insane on my unit.
The pop-up webcam’s bottom and the springs for reducing the display cable’s slack.
The WiFi card (Intel AC-8275) is non-replaceable.
Although the SSD is awkwardly under the heatsink, it can be wiggled straight out. I bought my X Pro on Taobao.com in China and it came with with a Samsung PM981.
The speakers under the speaker grill are tiny tweeters.
The tweeters fire upward through the grill, and they have a thin fabric filter cover.
Most of the sound comes from the bottom-facing speakers instead, which have much larger enclosures.
There is a cavity on each side of the touchpad, underneath the battery. The speakers could have extended into it like in the late-2017 HP Spectre X360 13t. Poor use of space? A little bit.
The hinges uses a simple rivet.
The display ribbon cables are similar to those of post-2016 MateBook Pros.
