Silent Fan with a Raspbee II on a Raspberry PI 4

Hardware
1

Hi,

I use HA on a Rapsberry PI 4. The fan I got is noisy, and I want to install a new ultra silent fan on it. I saw there are nice solutions, but they use the GPIO.

First issue:

  • The 5v PIN is used by Raspbee II
  • If i install a new fan with GPIO, I may loose the capability to install the Raspbee II

Is there a solution to install a very silent fan (and if you have the reference, would be great), and still be able to plug the Raspbee II?

Thanks

Regards

Benjamin
