Ultra4 fan speeds
I'd like to have a way to manually control or limit the fan speed for my Ultra4.
1804RPM is just too loud in my living room, I can tolerate 1650RPM.
I've tried running the recalibrate utility about 10 times since I bought the Ultra 4 in mid-December.
But the results have not been to my liking.The fan drifts back up to 1800RPM and NEVER goes back down.
At night my house gets down to 60F temps and logically the fan sensor should ramp down too right? Nope. it's stayed stuck at 1804RPM for 3 weeks now.
I rebooted the NAS this AM and its now at 1650RPM, lets see how long this lasts.
Any other ideas?

- After 40+ reads I guess no one has any information.
- I would like control RPM as well.
Does anyone know something about this? - The RPM speed is already controlled appropriately by the firmware.
What's your fan speed aleksey256? - I know it does.
But, like everyone I would like to make it slightly less loud.
My device is ReadyNAS 4 Pro.
Fan speed is ~ 1810-1830RPM.
When I run recalibrate function fan drops RPM to 1350-1400 and after that it growths slowly until ~1800.
The temperature is quite low inside of the box:
~ 31C for each drive (I have got 2 drives)
~ 42C for CPU (Temp 1)
~ 32C for the other sensor (Temp 2) (I suppose it is a main-board)
I would like to have it near with 1500-1600RPM which would almost noiseless.
I want to add that Temp 1 sensor sometimes disappears from the "Health" page. Is it an issue? - My fan speed was stuck at 1800 rpm so I restarted my nas and it settled at about 1100 rpm. It was great but then after a while the CPU warmed up to about 36 degrees and then the fan ramped back up to 1800! I'd love to know if someone can mak a plugin to support the manual control of the fan speed on it.

UPS 1 Not present NA - What version of RAIDiator are you running? There have been improvements in how fan speeds are controlled over time.
- I'm running 4.2.19. Have found that restarting is the only way to slow the fan speed down.
- You might find that the noise is coming from the psu fan. I have an ultra 4 plus and the psu has a 40mm fan which is not speed controlled and is quite noisy.
You might the thread I started.
I've resorted to just hiding it in a cupboard.
