如果没记错的话.r720 可以最大控制在 3600 转，和一开始的 13000 转还是差别巨大，2 硬盘整机 80w 不到。

Dell PowerEdge fan control with ipmitool - individual fan speeds
I couldn't find any info about this here or elsewhere on the internet, but I was playing around with ipmitool today and figured out how to control PowerEdge fans individually (at least on my T630).

The command to turn on manual control is:

ipmitool -I lanplus -H $IP -U $USER -P $PASS raw 0x30 0x30 0x01 0x00

and to turn it off is:

ipmitool -I lanplus -H $IP -U $USER -P $PASS raw 0x30 0x30 0x01 0x01

Controlling all fans at once can be done with:

ipmitool -I lanplus -H $IP -U $USER -P $PASS raw 0x30 0x30 0x02 0xff 0x##

where ## is 00 to 64, which is mapped to 0% to 100%.

All the above info is available all over the place, but it turns out the same command can be used to target individual fans too:

ipmitool -I lanplus -H $IP -U $USER -P $PASS raw 0x30 0x30 0x02 0x?? 0x##

Where ?? is a zero indexed fan number and ## is as above. Fan 1 is 0x00, fan 2 is 0x01, etc. If you use a an incorrect number it will throw an error on ipmitool and not cause any damage.

I needed this because my computer has different fan zones, and I wanted the CPU zone to have a lower RPM than the PCIe zones, and now I can. Much quieter.

I hope this is useful!
