Fan control

Thu Jan 26, 2023 6:26 pm

Hi,
most of the time my fans are stopped:
#  NAME                VALUE  TYPE
0  temperature         49     C
1  cpu-temperature     58     C
2  sfp-temperature     49     C
3  switch-temperature  49     C
4  fan1-speed          0      RPM
5  fan2-speed          0      RPM
6  board-temperature1  41     C
7  board-temperature2  38     C
8  psu1-state          ok
9  psu2-state          fail

And sometimes they spin at low speed:
#  NAME                VALUE  TYPE
0  temperature         50     C
1  cpu-temperature     59     C
2  sfp-temperature     50     C
3  switch-temperature  49     C
4  fan1-speed          3840   RPM
5  fan2-speed          3945   RPM
6  board-temperature1  42     C
7  board-temperature2  39     C
8  psu1-state          ok
9  psu2-state          fail

But then there are times, where the fans suddenly spin up, even if the temperatures are lower than usual:
#  NAME                VALUE  TYPE
0  temperature         48     C
1  cpu-temperature     57     C
2  sfp-temperature     48     C
3  switch-temperature  45     C
4  fan1-speed          7365   RPM
5  fan2-speed          7590   RPM
6  board-temperature1  40     C
7  board-temperature2  38     C
8  psu1-state          ok
9  psu2-state          fail

Then after 5 minutes it realizes that the temps are low enogh and it goes down to ~5000rpm and after some more minutes it goes back to normal.

WHY?
