Acceptable NVMe cache drive temps

Featured Replies

For quite a while now I have been getting alerts saying my cache drive is hot.  2 minutes later, the alert would be cleared.  But this would happen constantly.  A constant rollercoaster above and below the threshold.  Multiple times daily.  The warning temp threshold was set at 47C.  None of the alerts ever showed it was hotter than 49C that I could see.  I have set the threshold to 50C for now to calm the alerts, and see if it ever really hits 50C.  But I am curious if there is anything I can do to help this. The cache drive is this Crucial 1TB NVMe drive.  Here is the shares using cache and what they are set to:

 

appdata -> prefer  (transmission may be the most active app in here, but it is not in use on a daily basis)
domains -> prefer
handbrake -> Yes   (This container is not running, I don't currently use it)
isos -> Yes  (I only have 1 Ubuntu VM running right now)
system -> prefer
transmission -> yes

 

Any thoughts on a way to run this better or things I don't really need to use cache for that I could cut down on how busy my cache drive is?  Or should it be able to run this busy without getting that hot?  Just wondering what is safe to run it at.

The pdf here says operating temps 0-70C.  Not sure if it covers your exact model.  Saw 70C on a few sites while looking for something that seems official.

The trick I couldn't figure out was how to set different temp notification limits for different type drives... Hdd vs nvme vs SSD.

Thanks, you're right, I dug around and found the same thing.  Looks like 70C is the max temperature.  Maybe I'll set 55C as the warning temp, and 65C as a critical alarm.

 

As for setting temp notifications for different drives, it looks like you can just go to Main, and click on each drive, and set them individually on each one.  Not sure though how to set it for drive types.  Just each individual drive.  Thanks for the help!  Not sure why I didn't think to go look for specs on the drive lol.
