Hello,
it seems it has been never reported before but I noticed that Fan Test utility always spin up ALL the internal Fans regardless of what I have selected.
I have a MacPro 2009 wih Mojave 10.14.4 installed, I think it is a TechTool issue only because, for example, when I run the popular Macs Fan Control utility I can perfectly control every single fan.
