# fan speed controller for dell R710, R520 etc
Dells don't like having third party cards installed, and ramp up the
fan speed to jetliner taking off. But you can override this, servoing the fans to follow the temperature demand of the various components (disks via hddtemp, CPUs and GPUs via sensors, ambient temperature via ipmitool).
Dells don't like having third party cards installed, and defaults to
ramping up the fan speed to "jetliner taking off" mode when third
party cards or non-Dell disks are added in. But you can override

various components (disks via hddtemp, CPUs and GPUs via sensors,
ambient temperature via ipmitool).
This speed controller uses ipmi raw commands that seem to be similar
across a wide range of dell server generations (google searches for
`ipmitool raw 0x30 0x30 0x01 0x00` show it works for R710, R730, T130,
and I run this on my R520
This repo is forked from NoLooseEnds/Scripts, which contained
R710-IPMI-TEMP. I have extended it to work on my R520, being a bit
smarter regarding the CPU and HDD temps instead of just caring about
the ambient temperature. It uses ipmi raw commands that seem to be

It's got a signal handler so it defaults to default behaviour when
killed by SIGINT/SIGTERM.

I run it on my proxmox hypervisor directly, hence not needing any ipmi

once I have it firmly debugged.

# INFO
Forked from NoLooseEnds/Scripts, which contained R710-IPMI-TEMP - a
script to override the default fans behaviour in a Dell R710 idrac,
which defaults to powering up the fans to near full volume when third
party cards or non-Dell disks are added in. I have extended it to
work on my R520, being a bit smarter regarding the CPU and HDD temps
instead of just caring about the ambient temperature.
Other scripts may end up here too some day.
