moOde 5.4 Beta 2 is available

NOCTUA fans are really inaudible if you are not too close to them.  I use a 5V 40x10mm one, NOT the PWM variant, connected to the 3V3 pin.

With a large heatsink I get to 40º....

Nope. That’s the PWM variant. This one:

The low noise adapter is not there with this version, but it is the same as connecting to the 3V3 pin. These fans are so quiet that there is no need to buy the PWM version (that needs extra HW and SW to be added to Raspberry Pi and to the operating system). The non-PWM version is practically  inaudible while running at 3V3 (< 12Db at 75 cm of distance)

But.... that's a 12v fan.....how did you get it to work on the 3.3v gpio ??
