Incorrect Temperature Reported by NVME Drive

[nrgbistro]

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

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.
