This evening I am doing some temperature testing on the Samsung PM951 256Gb M.2 PCIe NVMe SSD (that's a mouthful!).I was quite surprised at the temperatures these drives run at, they need good cooling to keep them running at full speed.I am also shocked at how much they reduce in performance once they do throttle, I've discovered that the PM951's throttle temperature is 70C. At 69C the drive reads at 1,576MB/s and at 70C it reads at 315MB/s. So basically you have to keep your drive under 69C to maintain full speed.I'm carrying out a variety of tests which include no system fan, 50% and 100% system fan speeds with and without the underside vents covered. Firstly I am testing the system in an idle state and stressing the SSD with CrystalDisk. If I get time I will also repeat the testing whilst the system is in a completely loaded state.
