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![;)]( "Wink")
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:
