I recently installed a new NVME SSD in my server for a faster cache pool. I've gotten notifications of the drive being 84 degrees C, but when I feel the drive it is cool (certainly not 84 degrees C). When I look in the attributes tab I see Temperature sensor 1, which seems to always report either an accurate value or exactly 84c, and Temperature sensor 2, which seems like a more consistently accurate sensor (usually at 40c).

 

Is it possible to get Unraid to use Temperature sensor 2 instead of Temperature sensor 1? Should I be concerned that Temperature sensor 1 often reports 84c (this is a brand new drive)?

welcome to the "victims of samsung"  club 😁

Yeah, it happens now and then, it happens on all (or many) of their drives and its a firmware bug they guess.

No need to be concerned, its just annoying.

 

(And sadly, I dont know how to make unraid to switch over to sensor 2)

i second this , all(5) of my NVME drives are samsung , 3samsung 980 and 2 samsung 980 pro , the pros arent the ones that have this bug tho.

so my 3 drives are exactly 84c every now and then

now i found a thread that with the explanation and diagnostics that explains that the issue is only happening with regular samsung 980 and not the pro version

Tried adding that to my default boot and still see the issue (attached a screenshot of my addition in case it wasn't correct). For now I'm just going to set the drives warning temperature to 85 c.
