January 26, 20251 yr 2 minutes ago, spl147 said: 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 I understand - but I have a GPU and my fans go crazy unless I have my settings this way. These are dual Xeon 2680v4's, and they're currently idling at 53. I want the fans running at 46.8 constantly unless temps rise. Everything was working fine earlier during our earlier chat, and saw the poller every 30 seconds in the log. Now, it only polled once upon initial start. I appreciate your suggestions and will make some changes - but I still don't understand why there's no more additional polling.

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
January 26, 20251 yr OK - I changed it to the following, and now I'm seeing it poll every 30 seconds:

This makes sense. This would all be great to know, I have not seen any documentation. Appreciate your time.

Appreciate your time. how how it is in the room where your server is? what is "idle" to you? these are my settings (r730xd with 2x 2680v4): my fans have been idle all day (at 18%) and my cpus are in the 44c-47c range. something seems off. do you have the flat, low profile heatsinks or the tower heatsinks?

Inlet temp is 18c down here in the basement where I have the rack. Yes, low profile heat sinks because I have the midplane installed with 4 drives internally, in addition to the 12 3.5's in the front, and 2 2.5's in the rear. CPU's idle anywhere between 53-60c.

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
January 26, 20251 yr Just now, spl147 said: 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 Yes I have already ran the command, however if / when the server reboots it has to be manually sent again. I was previously using a docker container that sends the command, but now I have switched to using this plugin instead. ipmitool -I lanplus -H 10.69.xx.xx -U root -P calvin raw 0x30 0xce 0x00 0x16 0x05 0x00 0x00 0x00 0x05 0x00 0x01 0x00 0x00 Everything is running normally now.

CPU's idle anywhere between 53-60c. ah ok, that is the discrepancy then. i ditched the midplane and put the tower heatsinks in mine and i can get it to idle at 18% (or even lower if i wanted, really) and be pretty quiet and stay cool.

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
January 27, 20251 yr Okay, so I removed my other IPMI fan scripts and updated (plus, uninstalled and reinstalled) this plugin. I had an issue where the fans continued running at full speed despite correctly reading the IPMI data (fan speeds, temps, etc). I needed to go to Fan Control → Advanced View → change the max fan speed before it would actually modify the fans correctly. Not sure if I'll need to do this after reboot, but I thought it would be important for you to be aware of.
January 28, 20251 yr Question: how do I adjust the curve? My temps are reasonable, but the fans are still much noisier than they should be for the temps I'm seeing. I'm guessing in the Config Editor, but I can't figure out what I need to change.

I'm guessing in the Config Editor, but I can't figure out what I need to change. 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

I'm guessing in the Config Editor, but I can't figure out what I need to change. 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!

January 28, 20251 yr I'm making it complex because it's still very loud despite the reasonable CPU temp of 58 °C. As you can see, the top temp is 80 °C, which should give it plenty of movement to ramp speeds at that point. It's running at 9600 rpm, which is a bit too loud at that temp, IMO. So, I'm just hoping to be able to make tweaks to it. If not, no worries, it's still WAY better than without.

If not, no worries, it's still WAY better than without. 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
January 28, 20251 yr with your low temp at 20c and your current temp at 58c it thinks the cpu is hot, thats why the fans are loud
January 28, 20251 yr Ahh, now that is super helpful! Thank you for that. I've made those adjustments.
January 28, 20251 yr 4 minutes ago, Edival76 said: Ahh, now that is super helpful! Thank you for that. I've made those adjustments. 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 Edited January 28, 20251 yr by spl147
January 28, 20251 yr My motherboard seems to be detected correctly - see first image. I've set pretty low temperature limits - high of 60, low of 40 and max fan % of 50.1, min fan % of 10.1.
