ReadyNas 214 new system fan / fan control
The fan in my RN214 is too lound once it gets going, so I took a chance at replacing it with a Noctua NF-A9. It usually works fine, the resported RPM in the dashboard is typically a bit lower than t...
Hi aks-2 , any update to your investigation here?
I tried installing a Noctua NF-A9 FLX 3-pin fan, and had similar results as your A9-PWM version. The system would usually start, and run OK on any setting (as I recall), but then abruptly fail out of nowhere. If you found a setting that worked in SSH-land, please advise.
I also tried a 4-pin PWM fan, a Thermalright TL-9015W that runs at higher max RPM, thinking the issue might be RPM detection. In the garage, with the back panel removed but connected to the 3-pin header on the NAS, on power-up the fan spun up nicely. However, after I then reassembled the unit, brought it back inside, reconnected power and ETH, the unit won't spin up the fan at all. It's as if the fan settings got modified somehow, perplexing.
Anyway I'd like to run the Noctua with confidence. I could set it on Cool permanently but I fear the fan might still shut down in the middle of the night, during a backup or whatever. I don't want to cook my drives.
You'll see in another thread that I had a different disaster with my RN214, causing data corruption, that 'distracted' me for a while 😉!
Due to the issues running the Noctua, I reverted to the stock fan, whilst dealing with the corruption issue.
Let me check my notes for any more info I can offer. As far as I remember, the RN lowers the voltage too much, causing the fan to stall. Once stalled, the Noctua does not restart, even with 12V - although Noctua informed me that it should, so my fan must be a faulty example. They offered to send a replacement, but I did not take them up on that (yet).
I will check my notes and share anything else I can think of.
Why are you changing your fan, did the original fail?
The NAS has a setting to avoid frying your drives, so it will shut down before that if the temps get too high. Review your settings to enable: System / Settings / Alerts - tick "shut down system when the disk temperature exceeds safe levels" - but, I don't know what safe actually means here.
Thanks aks-2 - in my case, no fan failures, just noisy.
I generated the minimum fan speed override command that StephenB listed in your thread, except I set the min speed to 1500 instead of 1000.
So far, with about 24 hours run-time, it has worked. An hour ago, I swapped out the existing drives for 4 new HDD's, which caused the OS to go back to factory defaults. In this state, the fan failed (again). So I quickly added back in the override command, set the speed to Cool, rebooted, and it's working fine again. I also have alerts turned on - if the fan stops I'll get a notification so I can deal with it. Thanks again for all the data you shared, really helped to get closer to understanding the issue. The RPM reading is around 1580 (max speed for this fan is 1600). Per your notes, I can't be sure the fan is actually spinning at that rate. But I'm watching the CPU and drive temps, so far they're OK. Not as cool as the Delta fan on "Cool" setting though.
Also purchased a BeQuiet! Pure Wings 2 92mm fan, will give that one a try for grins.
# echo 1000 > /etc/frontview/min_fan_speed_override # systemctl restart readynasd

How did the BeQuiet work out?
And the Noctua too, still working ok?
