downloadski Posted September 5, 2012 Share Posted September 5, 2012 I am trying to get my PWM fans (Noctua) in control on the X9SCM-F mainbord. It works great on the Supermicro X7SPA i have. The sensor command shows the following devices: nct6776-isa-0a30 Adapter: ISA adapter fan1: 1620 RPM (min = 300 RPM) -> FAN-A on the mainbord = CPU cooler Noctua B9 PWM fan2: 0 RPM (min = 300 RPM) ALARM -> FAN 4 on the mainbord, not used fan3: 1491 RPM (min = 300 RPM) -> FAN 1 on the mainbord = Noctua F12 PWM and Noctua B8 PWM fan4: 1456 RPM (min = 300 RPM) -> FAN 2 on the mainbord = 2 Noctua F12 PWM fan5: 1422 RPM (min = 300 RPM) -> FAN 3 on the mainbord = 2 Noctua F12 PWM This is not matching, but when i log on with IPMI it matches the fan numbering on the mainbord, so the sensors command gives the wrong output it seems. OR it just starts numbering with 1 and continues to 5 ? In the IPMI display there is a red line at 600 rpm (minimal threshold i assume) With the mainbord setting on Full, it runs on 100%, all fans run ok, but noise level is too high. when i select Standard, it should be 50% (650 rpm) Optimal should be 30% (400 rpm) in both the standard and Optimal mode, the fans spin up, drop down and spin back up etc. (about a 25 second cycle) it seems to go down to 300 rpm, and than up to 1300 I found a post on hardforum that the threashold in the bios is set above 300 (700 actually) and this causes the spin up/spin downs http://hardforum.com/showpost.php?p=1038204386&postcount=5 Also that person claimed that FAN-A was linked to pwm1 and FAN1-4 are linked to pwm2 (so only 2 controls for all these fan headers) I assume if i can use PWM control from unraid with a fan script, it could put the lower limit above 700 to avoid this up/down behaviour. Is there a fellow X9SCM-F owner who uses PWM with a fan script ? (i tried to send settings with echo to pwm1 and pwm2, but this does not work) An other option i found on hardforum was to use IPMI to set another threshold. I do not find options for this in the IPMI View 2.9.10 from supermicro which i downloaded. Is there othere IPMI tooling that can do more ? Link to comment
downloadski Posted September 6, 2012 Author Share Posted September 6, 2012 I can control the fans it seems: root@Tower2:/sys/class/hwmon/hwmon1/device/echo 1 > pwm2_enable root@Tower2:/sys/class/hwmon/hwmon1/device# echo 255 > pwm2 root@Tower2:/sys/class/hwmon/hwmon1/device# cat fan5_input 1422 root@Tower2:/sys/class/hwmon/hwmon1/device# echo 120 > pwm2 root@Tower2:/sys/class/hwmon/hwmon1/device# cat fan5_input 718 root@Tower2:/sys/class/hwmon/hwmon1/device# echo 60 > pwm2 root@Tower2:/sys/class/hwmon/hwmon1/device# cat fan5_input 346 Now there seems not longer a 700 rpm threshold Link to comment
mrow Posted September 8, 2012 Share Posted September 8, 2012 For some reason when I enter "/sys/class/hwmon/hwmon1/device/echo 1 > pwm2_enable" in a telnet session I get the error "/sys/class/hwmon/hwmon1/device/echo: No such file or directory" but if I manually navigate to "/sys/class/hwmon/hwmon1/device/" and type "echo 1 > pwm2_enable" it works. What am I doing wrong here? I want to add this to my go script because without it the X9SCM-F is running my CPU fan at only 950 RPM whereas the base speed is supposed to be 2000 RPM. Enabling pwm2 brings it up to the proper speed though. Link to comment
dikkiedirk Posted September 8, 2012 Share Posted September 8, 2012 I don't even have a sensor command, I'm on 5.0 RC3. Must I install a package? Link to comment
downloadski Posted September 8, 2012 Author Share Posted September 8, 2012 I have installed perl via unmenu Also i use the script made by dstroot: http://lime-technology.com/forum/index.php?topic=11310.60 i had to alter 1 line only: ARRAY_FAN=/sys/class/hwmon/hwmon1/device/pwm4 into: ARRAY_FAN=/sys/class/hwmon/hwmon1/device/pwm2" Also you need to perhaps change a line for the fan to minitor the speed of: ARRAY_FAN_INPUT=/sys/class/hwmon/hwmon1/device/fan4_input # Used to track actual rpm values There needs to be a fan connected otherwise it iwll return 0 and not work i think.

StevenD Posted September 10, 2012 Share Posted September 10, 2012 I'm wondering if something changed as well. I'm running a SuperMicro C2SEE, and when I upgraded from 4.7 to 5.0 last week, PWMCONFIG no longer detects anything. Its not that big of a deal to me anymore since the other servers I added to the rack drown my unRAID box out anyway, but it would be nice to know why I can no longer do PWM fan control.

dikkiedirk Posted September 11, 2012 Share Posted September 11, 2012 I only see the coretemp output. The other one is missing. I use RC6-test2. Has there been something deleted from the kernel? I need test2 because I have a LSI2008 controller. I changed to RC6-test. Same result, just coretemp. How to get the PWM-output? Link to comment
downloadski Posted September 11, 2012 Author Share Posted September 11, 2012 you need to run sensors-detect to find these controllers i think. In the script you load the drivers for these modules: # Load adapter drivers: modprobe ipmi-si # Load chip drivers: modprobe coretemp modprobe w83627ehf Link to comment

StevenD Posted September 12, 2012 Share Posted September 12, 2012 I just checked and apparently my fans were spinning pretty slow. I noticed that since I switched to 5.0 my temps went up 4-6 degrees. Now that the sensors, and the fan speed control script, are working again, my temps are back down. I'm very happy! Thanks again downloadski!! Link to comment

aiden Posted October 23, 2012 Share Posted October 23, 2012 Also i use the script made by dstroot: http://lime-technology.com/forum/index.php?action=post;quote=153187;topic=11310.60;last_msg=165603 i had to alter 1 line only: ARRAY_FAN=/sys/class/hwmon/hwmon1/device/pwm4 into: ARRAY_FAN=/sys/class/hwmon/hwmon1/device/pwm2" Also you need to perhaps change a line for the fan to minitor the speed of: ARRAY_FAN_INPUT=/sys/class/hwmon/hwmon1/device/fan4_input # Used to track actual rpm values There needs to be a fan connected otherwise it iwll return 0 and not work i think. Downloadski, I wrote the original script (based on Starcat's work) that dstroot improved, cleaned up, and looped so there isn't a need for a cron job. Your modifications are correct, and in fact I made the exact same changes for my X9SCM board a while back. I just found this thread, but I wanted to confirm your changes are valid. You do need to make both changes you suggested, because without the fan speed detection, the script will fail. Good work on doing the digging around and finding the correct pwm variables. However, has anyone noticed that occasionally the board will force the fans to drop below 700? I modified my script to check every minute, so it resets to the correct speed, but it is annoying. I'm running the 1.1 bios, with the Fan Control Speed set on Standard in the bios. Anyone else having this issue? Link to comment
downloadski Posted October 26, 2012 Author Share Posted October 26, 2012 Aiden, i must thank you also than. It works for me, and never drops below 700 i think (would the mainbord not ramp it back up to full if so ?) I have to look in the script to force my cpu fan down as well. Perhaps not temperature controlled, but just in decrements of 10% down and check i not see the temp go up. I have a rather large fan and a 45 watt tdp cpu, so i never see it above 30 degrees celcius. The noise can be much lower without overheating the cpu i bet. Link to comment
aiden Posted November 3, 2012 Share Posted November 3, 2012 What value are you using for FAN_OFF_PWM? Link to comment
downloadski Posted November 19, 2012 Author Share Posted November 19, 2012 i have 45 configured now With 0 the systems ramps them up to full speed. The systems runs now with 1 TB samsungs that stay pretty cool. So i had to adjust the low temperature a bit down, and now it is ok again. Link to comment
