: If the firmware doesn't resolve the heat, adding a small thermal pad between the controller and the SSD casing (if metal) can help dissipate heat. : Due to its thermal profile, the
: In M.2 form factors, being placed directly under or next to a GPU can lead to ambient heat absorption, sometimes causing the drive to hit its 70°C–80°C thermal limit and shut down. Solutions & Maintenance
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
