This is interesting as it will help us combine the outside lights with one or more motion/light sensors: [Wayback/Archive] BJS 214 – Arnold-Schalter (this is the Busch-Jaeger® compatible version; for different installation systems like Gira and Jung, look at their site: [Wayback/Archive] Produktkategorien Privatkunden – Arnold-Schalter).
Basically it is a multi-function switch that to combine lights and separate motion sensors:

Some combinations of hardware/OS will result in high FAN speed despite low power usage on Dell R730/R730xd systems.
For me, altering the BIOS or iDRAC thermal settings did not solve it, nor did updating all firmwares to the most recent versions, so I went digging further.
Below are some links in case I want to resolve that (after figuring out that Dell R730 and R730xd are 13G systems).
There are lots of quotes in them as it will help me find back the information later on.
Note to self: I really wonder what the difference between raw 0x30 0xce and raw 0x30 0x30 is (I think 3rd party PCIe support and forced fan speed level) and how they differ from the system.thermalsettings.ThirdPartyPCIFanResponse setting.
