Tnx for the follow-up. According to the shop I could just snip the green
wire, so I've done that. I've set it to run at 60°C and the fan's not
turning (CPU temperature is 48°C).

 

My Pi 4B runs about that with no fan

 That's what I'm saying: it's 48°C when the fan is not running. Software
only allows to set a minimum temperature of 60°C before the fan starts
running, so I unchecked the setting and now the fan is turning all the
time. A fan with only 2 cables (red & black) should have been enough. I
don't know if there's a way to set that minimum temperature to 40°C...
 But yes, it's not really necessary and  I shouldn't have bought it. But
it was fun setting it up. I use RPi4 for Pi-Hole and PiVPN. I've played
a little with RetroPie, so maybe I'll give that another go, because I
have two RPi4 now.
 I used a Pimoroni Heatsink Case for the first one I bought:
<https://shop.pimoroni.com/products/aluminium-heatsink-case-for-raspberry-pi-4?variant=29430673178707>
 Temperature is around 40°C.
 The Unity V2 comes with a fan:
<https://www.kiwi-electronics.com/en/unity-v2-case-for-rpi-4-20096?search=unity>
 Temperature is between 30° and 35°C. (There's a real peak when I open
Fx.)
 

It's an interesting thought as to why one would use a fan at all. If its such a high compute task that you need one, maybe a bigger Pi or an Intel based machine is indicated.
I dislike fans. They fail.
