when using supplied blue thermal pad: 45C
when thermal pad changed to copper shim: 36C ~ 37C

fan quiet at 22db measured 30mm above setup

There are already multiple threads for this topic, do we really need another?

With this: https://uk.farnell.com/amec-thermasol/m ... dp/1892474
And this: https://noctua.at/en/nf-a4x20-5v

Now, no more than 40C while watching Youtube @ 1080p.
The Pi4 needs cooling regardless of what anyone says.

56C with heatsink and top popped off.

Did you do the EEPROM boot upgrade?
It saves 300mw.

I would disagree.
The Pi4 indeed runs hotter than previous model Pi, but sitting on my TV cabinet with no enclosure / case, I struggle to push it beyond 68°C while playing back 1080p YouTube videos via Chromium.

Can we please have this thread merged with one of the dozens of already existing threads?

The existence of an official plastic case that causes it to throttle undermines this. Many people will not use a Pi without some kind of enclosure.

My guess is that RasPi 5 will decrease temperatures on the board at least slightly, even if it means performance doesn't improve much over the Pi4.

I didn't measure it as I'm not happy running it like like. Going to wait for a heatsink and fan.

JB welded some heatsinks to the soc etc, put a blower on it, its much cooler.

Feel free to run it like that, it won't damage itself. I run my Pi4's for development with no case, no heatsink, no fan. It's fine. Rarely throttles.
