Expensive still for a fan aren’t they You don't need the 3rd wire, that is just a speed signal. I used to build a lot of PC's and Servers and fans were always coming in 2/3 wire mixes. I never had a 2 wire fan fail to operate on a 3 wire circuit - it just meant you didn't have fan speed in the BIOS and if it had speed control it often ran at full speed regardless, which frankly isn't so bad.

This has reminded me that maybe if I get some enforced time off I can I can relook at making a specific purpose, time domain reflectometer... Add it to the list of projects @Onoff...
