SuperMicro X10SLL-F: fan speed going up and down

[gewe]

Hello,

I am building a NAS4Free system, on a SuperMicro X10SLL-F motherboard. I have installed three Scythe Slipstream PWM casefans. These fans are running at a lower rpm than the threshold values. So the system thinks there is a fan failure, sets them to full speed, discovers they are all running, goes back to low speed, again falls below threshold, etc. So after 5 seconds of silence I get 15 seconds with vacuum cleaner sound, 5 seconds of silence, etc.

I can read the threshold values (and other system and configuration information) using freeipmi.
When I commit new values to the system, the new values are not saved. There is no error message, but the fan behaviour does not change, and reading the values again shows the old values.

How can I change the threshold values to below the lower rpm of the fans?

Hi,
I have same problem and similar board X10SL7-f and similar fans.
One thing I can do is to set all fans to max speed. Then all fans goes with its max speed. It´s quite noizy but not hoping up and down.
That board is done for server environment and server fans that works on higher rpms. If u use big fans like 140mm then mother board "dont like it"
Here is one more link (same question): http://forums.freenas.org/index.php?thr ... pmi.18377/

My level using the command line is not high. I would love to see a better explanation for it from an experienced person before I dare do it. It is quite risky to make mistakes in IPMI settings. You control the hardware directly.
I wonder if it is possible to control the settings from a graphical environment as in the original IPMI for this motherboard. It would feel safer. Tried to find it on the web but without success.
In the original IPMI u can not change threshold values.

One more thing about this board. IPMI has a dedicated LAN port on this board. But, if you not connected that port to any PC that port will be opened on other two LAN ports! That is danger! Think about it.
Dont konow yet if user can stop this function in bios.

I asked SuperMicro support, and they told me that there is a security limit of 300 rpm. So I replaced the fans with faster running fans, the Gelid Silent 12PWM FN-PX12-15. Not inaudible, but because I placed the system behind a board I can' t hear it.

I, as many other, want to have one silent NAS. I can solve this by using the fan controller like BitFenix Recon or similar.
This controller has NTC sensors that can be placed on CPU cooler and HDDs. Then fans will be controlled depending on temp.
But it would be nicer if the motherboard could run this job. The motherboard has the track of all temps.

I have X10SL7-f. From laptop running linux I used command 'ípmitool':

Code: Select all

ipmitool -I lan -U ADMIN -H 192.168.1.232 sensor thresh FAN2 lower 150 225 300

where FAN2 - sensor name, 150 - Lower Non-Recoverable valuse, 225 - Lower Critical value and 300 - Lower Non-Critical value.
Problem solved. Even after power down (switch off power supplier) values are restored correctly.
If you change values and nothing happens (values are applied but fans run full speed) try to reboot IPMI.

use ssh shell:

Code: Select all

pkg_add -r ipmitool

Code: Select all

cd /usr/local/bin

Code: Select all

./ipmitool -H [IPMI IP] -U ADMIN sensor thres FANA lower 100 100 100

restart system and check result with lower threshold (fan is now quiet):

I have a X10SLM-F... but should be the same...

My question is... FAN1 - FAN4 is using what temperature to control the FAN speed? Same goes for FANA

I can't find anything in regards to that. For example. I have CPU Heatsink fan connected to FAN1, Rear fan connected to FAN2, 2x Front fans connected to FAN3 and FANA and then FAN4 I have 2xfans connected via a splitter.

After setting the threshold on all the FANs; both upper and lower. The fans "act" normal now. BUT... what determines when the fan needs to be increased? just CPU?

In the end is there a way to 'assign' ... say FAN3 and FANA spins up higher RPM when it detects HDD temp hits beyond 55c... or when the motherboard PCH is getting hot, and spins up FAN4...etc...
