Hi,
I'd also love to see how to adjust/control fan speed on Raspberry Pi5. I think full speed until controlling firmware is loaded has been chosen by hardware design as a safe approach; it is common for many other devices that control fan speed.
However I have 1 rpi5 that I put in a totally passive aluminium case I got for cheap from China - the main point it need to have conductors to all 5 chips because most hot chip is RP1 if you use wired network and USB. I didn't try it but I guess Wi-Fi doesn't work in such an aluminium brick. But it is silent and below 60C under load Image may be NSFW.
Clik here to view.
CanaKit (Flicr) passive case with thermo conductor to CPU only is a complete garbage because RP1 chip gets to 75C and over and network interface drops packets, might be USB3 as well. For just using Wi-Fi and occasional USB access it might work though.
My another rpi5 has active cooler

with added heat pads for two smaller chips. It is shipped just with 3 pads for big chips and need pads with different thickness because heatsink is flat. And I seldom see that fan is rotating. And if it's spinning there is no much noise. I am writing from it and here are temps:
