They show a 5 blade and 7 blade fan, which is it. Looks like they send a 5 blade fan, is it loud?

I don’t have it in front of me at the moment but, if I remember correctly it’s a 5 blade. No it’s not loud at all; you can wire it up for 2 speed options. Low is basically silent as far as fans go and high is quiet enough to have a quiet conversation over without disruption, more then a few feet away and you can’t hear it. Also it does keep the chip temperature in the safe zone under a maxed out load for multiple hours.

What size is the fan?

Hello, friend, the size of raspberry pi fan is 35mm, model 3510, I hope it can help you.

Is this a suitable case to be fit on the back of a rp4 screen like this? https://www.amazon.com/osoyoo-touchscreen-raspberry-capacitive-compatible/dp/

Your link didn’t work.. but I looked it up and if it’s the same one I found than it will be a monitor that hangs loose outside of the case atta he’s by the ribbon cable. This touchscreen monitor attaches by screws to the board, and the miuzei case occupies those screw holes. You may be able to modify the miuzei case by screwing this monitor to it, but it may take some modifications. Maybe different screws or even some cutting.. so.. there’s no guarantee since this monitor is not designed to work with this case.

Could I use a potentiometer for a variable speed fan?

Theoretically, it is feasible to change the fan speed by adjusting the voltage through the potentiometer. We have not tried this part. You should test it yourself. I hope it can help you!
