Otherwise, accept the throttling – it’s the chip’s self-preservation mechanism.
The is a power-efficient quad-core processor (Cherry Trail) typically found in fanless tablets, 2-in-1s, and compute sticks. Because these devices often lack active cooling, they are prone to getting "hot" and thermal throttling to prevent damage. Understanding Overheating and Drivers
Microsoft Update often pushes incorrect drivers. You must manually install the correct packages.
Remember, for a processor with a Tjunction of 90°C, proactive cooling and the right software are the keys to unlocking stable, "cool" operation.
Increase the pressure of the stock heatsink against the processor by adding rubber washers, which can drastically improve heat transfer.
