SSD Operating Temperatures
Temperature Measurements
During our test benchmarks stress tests with a high-stress workload, we monitor the SSD temperature. As you can see the secondary internal sensor even reaches 89 Degrees C when the product is not cooled by air or a heatsink.
Under extreme load the controller heats up though, 80 Degrees C. For high-speed performance M2 SSDs we do recommend you to use a heatsink, as provided by pretty much any motherboard manufacturers these days. The Crucial P1 definitely needs one to prevent it from throttling.
