![]() ![]() Each of the charts has time moving from left to right, with the blue line displaying transfer speed in MB/s and the red line showing the temperature in degrees Celsius (measured using SMART). In a second run we report thermal performance of the completely uncooled drive. A first test run, to create a baseline, shows temperature and performance with a 120 mm fan directly blowing on the tested drive. We will test the drive in a typical case, installed in the M.2 slot between the CPU and VGA card, while it's getting hammered by non-stop incoming writes. On this page, we will investigate whether the tested drive has such a mechanism, how high temperatures get, and what effect this has on performance. All vendors include some form of thermal throttling on their drives as a safeguard, which limits throughput once a certain temperature is exceeded. Thermal ThrottlingDue to the compact form factor, M.2 drives lack the ability to actively cool themselves, usually having to rely on passive airflow instead. ![]()
