⚙️ PRODUCT CHARACTERISTICS

A metal plate screwed directly to the motherboard over the PCH chipset (marked UH1 on the board, next to the M.2 slot). The main heatsink covers only the CPU and GPU, so the chipset is cooled by this separate plate. The underside has a machined square contact pad pressed against the chipset, and the rest of the surface is covered with black insulating film. The plate is secured with 2 screws held in the tabs by retaining washers. The label reads ET1B4000110 TSL1.
