Silly questions, so apologies in advance...

 

I am using a toshiba/ocz rd400 (512) in a cache pool with an intel 540 (480).  The rd400 keeps triggering a health status failure due to the fact that it reports egg-cooking temps. 

 

Checking the data sheet, and, several bench summaries... operating range is up to 70*C and under sustained load it can top out at 85*C

 

I changed the disk thresholds to 65*C warning, 70*C critical  -- question 1:  where is unRAID pulling the default ranges from?  The disk?

 

question 2:  is it worth purchasing some thermal tape and a few IC heatsinks and place them on the IC and VAND chips?

 

First time using NVMe, and, those temps spooked me.

You can set custom temperature warnings to any device by clicking on it on the main page.

@j.b

 

I did (65,70)...

 

I just want to make sure that I am not doing something that will cause premature failure.

 

Also, NVMe drive is not showing up in pre-clear plug-in... is this a limitation of the script, or, am I doing something incorrect?

 

EDIT:  using Unassigned Devices Plug-in, I can select pre-clear via icon -- but it does not show progress in pre-clear plug in

 

I have a Samsung 950 Pro and also one RD400, both run pretty hot after big writes, about 70/75C.

 

For SSDs and NVMe devices use blkdiscard instead of preclear, less wear, e.g.:

 

blkdiscard /dev/nvme0n1

 

All data will be deleted.

Thanks j.b...

 

probably should have asked first... already running pre-clear.

 

Tracking using both htop (watching PID and checking /boot/preclear_reports)

 

Noted for future use.

 

Have you added any heatsinks to chips?

 

Waiting on a 960 pro...ordered on 11/5 for 11/15 shipping... that vaporware-unicorn has yet to materialize in the stable. 

 

Frown.

 

Not for the Samsung, the RD400 is the AIC version (with the PCIe adapter) and that comes with a thermal pad between the device and the adapter.

I am directly in the m.2 slot on the motherboard... no AIC.

 

I will watch temps, and, consider a riser if they continue to be alarmingly high.
