In the mean time, in another window, print interval=1s doesn’t show such things. This whole ordeal makes false alarms about fan being broken.
Any ideas?
ROS version? Device? Some fixes related to fans have been released recently on RC channel, see http://www.mikrotik/download changelog
board-name: RB1100Hx2
current-firmware: 3.24
version: 6.34.3 (stable)
Hm, I might try the RC to see if things go away.
version: 6.35rc42 (testing)

And, for good measure: fun with volts!

Device is functioning normally, and I doubt it would be possible @7.8V - this is on 6.35rc42, on RB433AH.
On 2011UAS v6.34.3:
[admin@MikroTik-VF] > /system health print
voltage: 1106.5V
Nice one. But is it permanent, or just one “lucky” readout?
Seems to be permanent. I can’t reboot just now to see if this solve the problem.
Well, fun with fan continues…

Wonder if this is some hardware problem. According to graphs, there weren’t any such problem during the day.
