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:

Temperature is between 30° and 35°C. (There's a real peak when I open
Fx.)
