SSD Operating Temperatures
During our test benchmarks stress tests with a high-stress workload, we monitor the SSD temperature. The unit idles at roughly 45!50 Degrees C, the peak stress temperature measured hovers at roughly 71 Degrees C on the controller if not cooled. So yeah, a motherboard m.2. heatsink cooling is recommended to prevent thermal throttling (a hot state where the controller will slow down in order to manage and lower heat levels).
