- it might be, but that thread is closed and I have no idea how to fix it? the temperatures are ok, so why does it complain about the speed? or, on the other hand, why does it let the speed drop too much?
- is there any way to fix it?

I believe (provided to me via support - not tested) this will set the minimum speed to 1000 (change as desired). Delete the file and you'll undo what you did.
I use numerous Pros 2s and they yo-yo under load. Fan goes from low 700s to around 1,300. The temperature gets to roughly 85C before it ramps up. Quickly the temperature jumps down and it takes a while to get back to the 700s.- where do i put this file?
- That needs to be done through SSH/TelNet.
- I understand that, however that's a script file which needs to be executed during each boot my guess, so it matters where I put it?
- You are correct in thinking that the folder matters. The confusion here is that this is not a script, these commands are typed once into ssh.
This part is the key:
# echo 1000 > /etc/frontview/min_fan_speed_override
It creates a min_fan_speed_override file holding 1000 in /etc/frontview
# systemctl stop readynasd
# systemctl disable readynasd
# systemctl enable readynasd
# systemctl start readynasd
This restarts the NAS application (and I think it would likely be ok to simply reboot the NAS instead). - ok, so it sticks even after a reboot?
- Yes. If you want to change it, you need to replace (or delete) the min_fan_speed_override file in /etc/frontview.
