ReadyNAS Pro 6 CPU-fan Calibration button
INFORMATION:
Netgear ReadyNAS Pro 6
Firmware: 4.2.31
X-Raid 2
Fan SYS 936 rtm
Fan CPU 2156 rtm
Temp SYS 45° Normal 0-65°C Recalibration OK
Temp CPU 25.5°C Normal 0-85°C OK
PROBLEM
I cleaned the CPU fan (4-pins on mainboard) and replaced the thermal paste. Upon restarting the NAS, In the Status-logs, I can see both fans (SYS and CPU) with speed and temperature but only the SYS fan has a button for recalibration. The CPU fan is constantly turning on a high speed (always above 2000 rtm) and there is no possibility for Calibration. I think to remember that this was possible before the cleaning. (Not absolutely sure.)
QUESTION
How can I get back the button for calibration of the CPU-fan?

It's been a long time since I ran 4.2.x on a Pro6, but I don't remember two calibrate buttons. But one thing that may make a difference is whether your Pro uses a 4-pin fan connected next to the CPU or a three-pin one connected to the daughterboard. Or did you, perhaps, plug it into the wrong connector for your fan type?
Thanks for your answer.
I use a 4-pin connected to the mainboard. I plugged it back into the same plug as it was before the cleaning and at the time, it was working fine (at a lower speed).
Of course, the thermal properties of the heatsink compound improve with age in the first few weeks, so things may change as time goes on. I only have one Pro6 still set up, and it's on OS6, but it's CPU fan runs in the 1600Hz range on the "Balanced" setting. When I had three NAS running side-by-side, they ran a little hotter, so the fans were a bit faster.
Sorry, I didn't see your answers. So there is just no Calibrate button for the CPU-fan.
Thanks for both of you, Sandshark and StephenB.for your answers.
