WD Red 8tb 42C and 48C

Post by beshur »

Hello!

I have ts-253B and have recently installed the second drive. Both are WD Red 8Tb (WD80EFAX), but one is helium-filled (it has idle temp of 42C).

So without any serious load the drives are at 48C and 42C. This looks like a bit too hot.

Tried:
- swapping the drives in bays
- placed the NAS on top of the table (should be better ventilation)

No major effects to the drives' temperature.

Is it ok? What should I do?

No, I haven't. It's already at 1600, but I'll try.

I ran the fan at 100% for a couple of minutes, and the hot drive dropped 3 degrees.

Setting the fan mode to thresholds also not very viable - the lowest "hot" threshold is 45 degrees, which leads to the fan turning on and off every 20 seconds or so.

Is my situation unique?

Just checked my NAS here are the values, but it might be a bit unfair as it's a (lot) roomier 16-bay NAS:

CPU: 37 °C / 98 °F
System: 29 °C / 84 °F
M2-SSD: 31°C / 87°F
SATA-SSD: 34 °C / 93 °F
HDD: 42 °C / 107 °F

CPU-Fan: 2580 RPM
3x System-Fans: 660 - 720 RPM

This is during heavy load, as a HDD-rebuild is running at the moment.

This seems indeed very hot:
I have 4 of these which run between 27-30C
Even my 4 WD purple 4GB which are constantly writing/recording videos from 16 cameras and should be fairly similar run between 34-36C. Granted my NAS is quite different. You probably have a ventilation problem.

How can I verify the ventilation problem?
The fan seems to work fine.
As I mentioned I tried putting it in more spacious location.

Removed the front disk bay door, the temperature went down to 38/46 degrees (38 for Helium one).
Also tried playing with the fan modes, but not to much effect.

Look for airflow blocking things as it appears to be your problem. Maybe even air circulation around the NAS itself.

Thank you for the suggestion.

I have moved the NAS up on a table, and even tried laying it on its side (since the largest exhaust port that leads to the reactor core ;)) is on its bottom. No change in temperature though.

Got some more advices from QNAP support and a tool to check background jobs that prevent disks going to standby (but haven't gone through the points just yet).

In the meantime I changed the standby inactivity time to 5 minutes (from 30 minutes) - and it helped a lot - I can hear the disks spinning down and up when I'm around, and the temperatures went down to 33C and 39C respectively.

This is pretty strange. I just moved my 4 disk array to another QNAP NAS (473) and the temperatures remain in the low 30s and without having to put my drive in standby as they are constantly recording backups from my various MacOS devices.

Apparently the last thing keeping the drives from sleeping was the Qsync.
I believe it polls NAS periodically, not allowing the disks to effectively cool down.
I don't really use it much, so I paused sync, and start it up on the rare occasions I need to sync stuff.

Also I scheduled the Mac TimeMachine backups to only happen once a day, close to midnight.

Now my temperatures in standby are around 28-30 (Helium), 32-34 (non-Helium).
