“(Two 8GB) I was mainly after more memory than Pi4's in my cluster. So far, the Pi5's, on similar loads, even without the active cooler running, seem to run a little cooler than the Pi4 (no cooling - just some small heatsinks). I found it will run OK on a standard 5V (beefy) USB-C adapter without flagging any isssues, however I've now installed them with a 5.1V power supply fed through the pins (using 2x5V and 2xGND) which works fine.”
