Hi Aj, Yes the ADM1026 has fan control, but the ADM1026 is mentioned only as the chip used by the IPMI BMC on it's private i2c bus. All IPMI BMCs use normal hardware monitoring chips (AFAIK) at a lower level, but usually the documentation isn't always so complete as telling you which. The BMC is essentially another separate computer running on your motherboard along with it's own CPU, memory, firmware and even i2c bus. The chip is likely only accessible by the IPMI BMC directly, so unless the IPMI BMC has some sort of support itself for a command to set the pwm you are out of luck. The only sensor write commands in IPMI 1.5 are for setting alarm limits, enabling/disabling sensors and setting sensor types, so I don't see how you could set the fan speed in anyway via IPMI. I think the only possible way to set the fan speed then would be if (like my board) the IPMI BMC shares the same i2c bus as the rest of the machine, except the bios blocks access to it, and you somehow unblock that and access the ADM1026 directly (which by the way the IPMI BMC wouldn't like, and would likely start complaining). In my case I can do that by flashing with another vendor's bios, but my motherboard is a bit unusual, and I wouldn't recommend trying anything like that. Yani
