The culprit is not a virus or a failing NAND chip. It is a thermal design flaw in the controller itself. This article dives deep into why the runs so hot, the difference between heat and throttling, and how to fix it permanently. Part 1: What is the Phison PS2251-07 / PS2307? Before solving the heat issue, we must understand the hardware.
A: Yes, many revisions of the DT100 G3 use the PS2251-07. It is notorious for overheating.
