I have a SuperMicro 4027GR-TRT server that I am running multiple GPUs in. I would like to set the cases fan speed higher that what they are right now using IPMI, although I am not sure how to do it.
I am currently able to interact with the system using
ipmitool using raw commands. I have been able to get and set the systems fan settings using the following commands (via http://www.supermicro.com/support/faqs/faq.cfm?faq=18009):
ipmitool -I raw 0x30 0x45 0x01 0x00
This will set the fans to "Normal, Full or Optimal". My fans are currently running on the optimal setting at right around 4,700 RPM.
How can I increase my case fan speed to ~8,000 RPM or so? I have tried changing the fan thresholds but I don't understand what those settings are doing.
Is there a way to set the fan speed to a single value? If not, how would I set the lowest threshold so that its lower limit is 8,000 RPM?
My current threshold settings are as follows:
FAN1 4800.000 | RPM | OK | 300.000 | 500.000| 700.000| 25500.000 | 25500.000 | 25500.000
I have tried setting the lower threshold to 8,000 but that made all of the fans run at 14,000 RPM. I am not sure how the lower thresholds work.
