SuperMicro - Control Fan Speed via IPMICFG (Command Line)

Issue:

Need to change the fan speed for SuperMicro servers.

Resolution:

1. Download and extract IPMICFG on the target server
1. https://www.supermicro.com/SwDownload/SwSelect_Free.aspx?cat=IPMI

2. Open CMD prompt as ADMIN
3. Change Directory to the extracted folder, and drill down to the Windows\64bit folder
1. EXAMPLE: cd c:\ADMIN\Installs\IPMICFG_1.29.0_build.181029\Windows\64bit\
4. To view the current Fan Profile
1. RUN: IPMICFG-Win.exe -fan 
5. To change the current Fan Profile
1. RUN: IPMICFG-Win.exe -fan x
1. x can equal one of the following:
1. 0 for Standard (BMC control of both fan zones, with CPU zone based on CPU temp (target speed 50%) and Peripheral zone based on PCH temp (target speed 50%))
2. 1  for Full (all fans running at 100%)
3. 3 for PUE2 Optimal (BMC control of the CPU zone (target speed 30%), with Peripheral zone fixed at low speed (fixed ~30%))
4. 4 for Heavy IO (BMC control of CPU zone (target speed 50%), Peripheral zone fixed at 75%)
2. EXAMPLE: To set fans to Standard
1. RUN: IPMICFG-Win.exe -fan 0
