I just finalized building my second Unraid and I am doing a pre-clear on all drives, about 7 of them. The CPU is screaming for sure.  Is a bit of a stress test as well.

 

As the pre-clear is running the NVME drive (SAMSUNG_MZVLB256HAHQ-000L7) temperature went off the charts from 38 to a 64 C.  Is this normal?  I am sure the temperature will go down as the pre-clear on all drives will finish?  Did I damage my nvme drive?

NVMe devices can easily get to 70C or close to that during heavy writes, but you should really avoid preclearing flash based devices.

I use NVMe as cache drive. It routinely would get to 75C during normal write activity.

Added an after-market M.2 heatsink (available from Microcenter and others) to the NVMe M.2 stick.

The temps now run normal on it.
