The question "50 - 52 C NVMe SSD idle temps - Normal?" is based upon the assumption that the idle temperature is a measure to determine if your device is performing correctly.
So I started investigating and after a little while I noticed that my cpu is idling at a temp between 100 C - 105 C (yes, Celsius) through msi after burner , I tried "open hardware monitor" and it is reporting the same temps, I rebooted into bios and it is showing constant 96 C.
With temps like this, if you’re going to stick the SN770 in a motherboard that doesn’t have M.2 heatsinks, make sure there’s good air-flow over the drive. Enabling Gaming Mode on the SN770 essentially disables any power-saving / sleep features, so the drive is always at the ready.
Temperature sensors showing high CPU temps, CPU not super hot Ask Question Asked 12 years, 3 months ago Modified 2 months ago
However, GPU overclocking is extremely common, and many situations arises where people push GPUs to extreme temps - thus resulting in a perception that GPUs have higher temperature tolerances than CPUs.
