Will there be any new HATs for the Raspberry Pi 4?! I would like to see a fan HAT with an EMMC.

Neither the Foundation or Trading announce products before they are released :lol:

Think back to last week 8-) :lol: 8-)

Saying that - expect lots of suppliers to jump on this need :D

Interesting. It doesn't say anything about controlling the fan speed. I'd want that for two reasons...first, at 4200rpm, it's going to be a bit noisy, and second,one may not need full speed all the time. I'd also like to see the option of adding a grill to keep fingers, especially small ones, out of the fan blades.

You can turn it on and off based on the temperature. Go to the 18 minute mark in this video for some info.

One of these difussers mounted on tall stand offs should keep fingers out.

I like the black Ninja ones myself. You could also drill some holes in it if you wanted for good air flow.
I haven't found a better solution or i would have posted it.
