A: Yes, many revisions of the DT100 G3 use the PS2251-07. It is notorious for overheating.

Manufacturers save money by using thin plastic shells with no thermal pads. The controller has no path to dump heat into the outer casing. Instead, the heat stays trapped inside, cooking the NAND chips and the controller itself. Part 3: The Symptoms of an Overheating PS2307 You don’t need a thermometer to diagnose this. If your Kingston or Corsair drive exhibits the following, you are suffering from the classic "PS2307 hot" syndrome:

A: No. Condensation will short-circuit the PCB. Let it air cool for 20 minutes. phison ps225107ps2307 hot

If you have searched for the term , you are likely experiencing the same frustration as thousands of other USB flash drive users. You plug in your drive—often a Kingston DataTraveler, Corsair Voyager, or Patriot Memory stick—and within minutes, the casing is too hot to touch. Data transfer speeds start high (100+ MB/s) but suddenly plummet to single digits (2–5 MB/s), and the drive may even disconnect from Windows with a “USB Device not recognized” error.

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. | Symptom | What is happening | |

Early revisions of the PS2307 firmware had no temperature throttle. The controller would run at full speed until the NAND flash's solder joints began to reflow (soften). Later firmware added throttling, but it is reactive, not preventative. By the time the throttle kicks in, the drive is already dangerously hot.
