The SM2259XT is a DRAM-less controller, meaning it uses a small portion of the system’s RAM (HMB) or a tiny internal cache instead of a dedicated chip on the SSD. This architecture requires the controller to work harder during sustained writes, leading to increased heat. 1. Aggressive Firmware Profiles
Manufacturers often "overclock" the firmware settings to squeeze every bit of speed out of the controller to meet advertised benchmarks. This aggressive tuning can cause the chip to reach 70°C+ quickly, triggering a or severe throttling . 2. Poor Thermal Reporting sm2259xt firmware hot
If your drive is showing high temperature warnings or experiencing thermal throttling, it often comes down to how the manages power and thermal limits. Here is a deep dive into why this happens and what you can do about it. Why the SM2259XT Runs Hot The SM2259XT is a DRAM-less controller, meaning it
