NetApp H610S Fan speed too high – controlling with IPMI

I was chatting with someone on the NetApp Discord today – they’d just bought a used NetApp H610S aka NAF-1703 aka Quanta D52B-1U, and installed Proxmox on it, but the fans were running too high. This was a WAF issue, and they were looking for a way to calm it down.

We did some digging and found this document on the IPMI commands for a similar platform – but they didn’t work on this one.

Some digging around suggested that they needed to use

ipmitool raw 0x30 0x39 0x00 0x00

instead of

ipmitool raw 0x30 0x39 0x01 0x00

What’s the difference? Who knows, but it worked.

Hope this helps someone!
