stop fan control, delete dynamix.system.autofan2.cfg rename dynamix.system.autofan1.cfg to dynamix.system.autofan.cfg, remove the line from the go script. then reboot, then start fan control

very nicely put.

@Edival76here is the ipmitool commands to play with fan control to find the perfect cpu idle setting: stop fan control in the plugin Set fans to manual control: ipmitool raw 0x30 0x30 0x01 0x00 set fan speed: ipmitool raw 0x30 0x30 0x02 0xff 0xXX (replace XX with a value from the chart below: 00-64 (00=0% and 64=100%) 00 -> 0% 01 -> 2% 02 -> 3% 03 -> 5% 04 -> 6% 05 -> 8% 06 -> 9% 07 -> 11% 08 -> 12% 09 -> 14% 10 -> 16% 11 -> 17% 12 -> 19% 13 -> 20% 14 -> 22% 15 -> 23% 16 -> 25% 17 -> 27% 18 -> 28% 19 -> 30% 20 -> 31% 21 -> 33% 22 -> 34% 23 -> 36% 24 -> 38% 25 -> 39% 26 -> 41% 27 -> 42% 28 -> 44% 29 -> 45% 30 -> 47% 31 -> 48% 32 -> 50% 33 -> 52% 34 -> 53% 35 -> 55% 36 -> 56% 37 -> 58% 38 -> 59% 39 -> 61% 40 -> 62% 41 -> 64% 42 -> 66% 43 -> 67% 44 -> 69% 45 -> 70% 46 -> 72% 47 -> 73% 48 -> 75% 49 -> 77% 50 -> 78% 51 -> 80% 52 -> 81% 53 -> 83% 54 -> 84% 55 -> 86% 56 -> 88% 57 -> 89% 58 -> 91% 59 -> 92% 60 -> 94% 61 -> 95% 62 -> 97% 63 -> 98% 64 -> 100%

are your fans PWM? from the screenshot it shows your fans are at 0%

with the server sitting idle, play with the min fan speed setting to find the lowest you can set it without the cpu heating up. it's a little bit of trial and error. i used ipmitool from the command line to change fan speeds to find my values

with your low temp at 20c and your current temp at 58c it thinks the cpu is hot, thats why the fans are loud

your settings are still way incorrect, your cpu will never see 20c. put your low temp at the temp your cpu idles at, try 35c. min fan speed should be lowest speed to keep cpu at idle temp. max speed is as loud as you want it to be. try 50-60

did you try the settings posted by @xrichnj?

i just do not understand why you insist on making this so much harder than it is. Choose your sensor to monitor, set high temp, low temp, max fan speed and min fan speed. thats it. the plugin does the calculations to adjust the fans based on the values you input above. THATS IT!

The fan curve is based on min and max fan speed and min and max temp. Low temp should be close to your idle temp, and max should be close to the max temp you want when your fans are screaming. Min fan temp should be the lowest possible to maintain idle temp and max should be as loud as you want to deal with while being able to keep the cpu under max

You should not have to re enter it, it’s enabled or disabled permanently. I ran it once years ago, it’s still disabled after many reboots. here is the white paper: https://fohdeesha.com/docs/store/perc/ThirdPartyPCIFanResponse.pdf

It’s because of the gpu, dell has a pcie override that blasts fans, there is a command to disable it but he doesnt seem interested

Have you ran the command in terminal to override the pcie not supported issue (gpu not using dell firmware or not a supported card) it’s because you settings are to narrow and the log will not reflect if nothing has changed

Your settings are crazy, if you are using cpu as your temp to poll you only have a 10c differential, no to mention your low temp threshold is below your current temp. Low temp should be close to your idle temp, and max should be close to the max temp you want when your fans are screaming. Min fan temp should be the lowest possible to maintain idle temp and max should be as loud as you want to deal with while being able to keep the cpu under max. it’s a try and see to find the proper mix, i used the ipmi-raw command in terminal to play with fan speeds, and the cpu corefreq plug-in to load the cpu and adjust the fans using the ipmi-raw command to find the right balance

Perhaps we should add that to the help text

perfect, thank you for considering my changes

Thank you for the quick fix. i have submitted another pull request, it is just a visability change. it adds bold type to the main description, and adds a description for the spundown sensor fields. see attached photo.

confirmed it updates normally

i found the issue, even though it says the plugin updated, the ipmifan script did not have the code change in it. i manually changed it and can confirm it is fixed. curious as to why the update did not work properly? UPDATE: just looked and the plugin has reverted to the 1.21.25 release

yes

still seeing this in the log: HDD Spundown using Temp(104 °F)
