I have just upgraded to Ubuntu 15.10 and almost immediately my CPU fan started speeding and slowing without good reason even when the PC is idle.
I tried various things but then found that if I leave the computer off for a long time and let everything cool down then when I boot from cold the CPU fan is stable.
To test my theory of cold start out I then ran
sudo cpupower frequency-set -g powersave
followed by
sudo cpupower frequency-set -g ondemand
The final mode is the initial mode. Almost immediately as soon as I moved to powersave mode the erratic fan speed started. It did not stop when I returned to ondemand.
Temp fix for this behaviour is - go and have a cup of coffee and let the computer cool down when you restart: shutdown then start from cold.

I have just upgraded to Ubuntu 15.10 and almost immediately my CPU fan started speeding and slowing without good reason even when the PC is idle.
I tried various things but then found that if I leave the computer off for a long time and let everything cool down then when I boot from cold the CPU fan is stable.
To test my theory of cold start out I then ran
sudo cpupower frequency-set -g powersave
followed by
sudo cpupower frequency-set -g ondemand
The final mode is the initial mode. Almost immediately as soon as I moved to powersave mode the erratic fan speed started. It did not stop when I returned to ondemand.
Temp fix for this behaviour is - go and have a cup of coffee and let the computer cool down when you restart: shutdown then start from cold.

I have just upgraded to Ubuntu 15.10 and almost immediately my CPU fan started speeding and slowing without good reason even when the PC is idle.
I tried various things but then found that if I leave the computer off for a long time and let everything cool down then when I boot from cold the CPU fan is stable.
To test my theory of cold start out I then ran
sudo cpupower frequency-set -g powersave
followed by
sudo cpupower frequency-set -g ondemand
The final mode is the initial mode. Almost immediately as soon as I moved to powersave mode the erratic fan speed started. It did not stop when I returned to ondemand.
Temp fix for this behaviour is - go and have a cup of coffee and let the computer cool down when you restart: shutdown then start from cold.

CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us.
hardware limits: 1.20 GHz - 2.80 GHz
available frequency steps: 2.80 GHz, 2.80 GHz, 2.67 GHz, 2.53 GHz, 2.40 GHz, 2.27 GHz, 2.13 GHz, 2.00 GHz, 1.87 GHz, 1.73 GHz, 1.60 GHz, 1.47 GHz, 1.33 GHz, 1.20 GHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 1.20 GHz and 2.80 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 1.20 GHz.

I have just upgraded to Ubuntu 15.10 and almost immediately my CPU fan started speeding and slowing without good reason even when the PC is idle.
I tried various things but then found that if I leave the computer off for a long time and let everything cool down then when I boot from cold the CPU fan is stable.
To test my theory of cold start out I then ran
sudo cpupower frequency-set -g powersave
followed by
sudo cpupower frequency-set -g ondemand
The final mode is the initial mode. Almost immediately as soon as I moved to powersave mode the erratic fan speed started. It did not stop when I returned to ondemand.
Temp fix for this behaviour is - go and have a cup of coffee and let the computer cool down when you restart: shutdown then start from cold.

After upgrading to Ubuntu 15.10 my CPU fan started speeding and slowing without good reason even when the PC is idle.
This has been bisected to commit f989e55452c74b4f7b22c889b8ec9f1192aaeec4 :
i8k: Add support for fan labels
This patch adds labels support for fans if SMM function with EAX register
0x03a3 reports it. This information was taken from DOS binary NBSVC.MDM.
Additionally this patch change detection of fan presece. Instead reading fan
status now detection is based on new label SMM function. Dell DOS binary
NBSVC.MDM is doing similar checks, so we should do that too.
This patch also remove I8K_FAN_LEFT and I8K_FAN_RIGHT usage from hwmon driver
part because that names does not make sense anymore. So numeric constants are
used instead. Original /proc/i8k ioctl part was not changed for compatibility
reasons.

WORKAROUND: Shutdown. After it cools down for a while, turn it on.
