[SOLVED] Fancontrol constantly spin up fans

Hello,

I have set up fancontrol according to this: https://wiki.archlinux.org/index.php/fan_speed_control, but whenever I use it the fans constantly spins up because cpu temperature spikes back and forth. When I am not using the fancontrol and actually have my cpu fan at a lower rpm, my temps are steady,

At first I thought it was my nvidia card (fans where spinning so high before fancontrol so I did not notice)
I tried this https://wiki.archlinux.org/index.php/NV … ries_cards even thou I have a 600 serie card, but it made no difference.

Then I switch to let my motherboard have full control over the fans, and I have no problems, but as soon as I turn on fancontrol the cpu temerature keeps spiking and fans spins back and forth, and that is with a higher base rpm then what my motherboard have set for the cpu fans.

My /etc/fancontrol configuration

# Configuration file generated by pwmconfig, changes will be lost
INTERVAL=10
DEVPATH=hwmon0=devices/platform/coretemp.0 hwmon1=devices/platform/nct6775.656
DEVNAME=hwmon0=coretemp hwmon1=nct6779
FCTEMPS=hwmon1/pwm1=hwmon1/temp7_input hwmon1/pwm2=hwmon0/temp1_input hwmon1/pwm3=hwmon1/temp2_$
FCFANS=hwmon1/pwm1=hwmon1/fan1_input hwmon1/pwm2=hwmon1/fan2_input hwmon1/pwm3=hwmon1/fan3_inpu$
MINTEMP=hwmon1/pwm1=20 hwmon1/pwm2=20 hwmon1/pwm3=20 hwmon1/pwm4=20
MAXTEMP=hwmon1/pwm1=60 hwmon1/pwm2=60 hwmon1/pwm3=60 hwmon1/pwm4=60
MINSTART=hwmon1/pwm1=90 hwmon1/pwm2=32 hwmon1/pwm3=90 hwmon1/pwm4=90
MINSTOP=hwmon1/pwm1=90 hwmon1/pwm2=32 hwmon1/pwm3=90 hwmon1/pwm4=90
MINPWM=hwmon1/pwm1=90 hwmon1/pwm2=32 hwmon1/pwm3=90 hwmon1/pwm4=90
MAXPWM=hwmon1/pwm1=255 hwmon1/pwm2=255 hwmon1/pwm3=255 hwmon1/pwm4=255

I am fine with my temps and noise now that I tweaked motherboard control over fans, but it would be interesting to hear if other people have had the same problem as I did, and if a solution exist. Fancontrol gives me better control over the fans, so if I can use that  - I would prefer it.

Martin

Re: [SOLVED] Fancontrol constantly spin up fans

Hello,

The reason for the problem was because I had a typo in my configuration file in "/etc/modules-load.d/" in order to load up the lm_sensors, wich ofcource broke the setup and made those spikes I experianced.
