Hello theWhip. Welcome to LQ.

It seems the new firmware fix is certainly "fixing" things good and proper: Raspberry Pi 4 - new VLI firmware issues

It's been reported that the new VLI firmware fix lowers the general operating temperature of the SOC by only a few degrees and that's without any additional cooling. New Raspberry Pi 4 VLI Firmware Lowers Temperature by 3-5°C. If the new firmware only lowers temperatures by 3-5 degrees Celsius, that's not very much and is approx. the same as adding a 28x28x20mm heatsink to the RPi4 SoC - without a fan. I have tested with this heatsink setup and the thermal issue is still very apparent. The only way to cool down the RPi4 SoC effectively is to use a heatsink and fan as an additional cooling solution.

If you would like to install the new VLI firmware "fix" [as recommended by Raspberry Pi Engineers] to solve the thermal issue(s): Following a successful trial with our alpha testers, we are releasing a new firmware build for the USB3 host adapter.... Good luck if you do!

A guy I spoke to is running his Raspberry Pi 4 Model B in a GeeekPi Acrylic Case with a Noctua 40mm 5v fan fitted and he reports the operating temperature to be ~35'C when idling at the command prompt. That's without any heatsinks fitted at all.

Apparently, so I'm told, the Noctua 40mm fan is very efficient and quiet. I'm looking to get one.

I like that GeeekPi Acrylic Case, yes Noctua 40mm fans are really cool!
