Pi4 Cooling

Sun Jul 14, 2019 2:54 pm

The over-temperature icon is flickering on and off continuously on the Pi4/4 I'm running as a second desktop, alongside my 'proper' desktop. It's fitted with heatsinks and mounted in a modified old-type official case with both side panels and the top cover left off. On current Buster it's running one program – the Chrome browser with two tabs open, one of them displaying a national newspaper and the other streaming BBC iPlayer Radio. It's not an especially warm day.

By and large I'm quite impressed with this new version, but I think we're kidding ourselves if we think it's suitable for use as a desktop without a cooling fan.

Edit: I note that the new Pi4 case, if you can get one, doesn't have the removable side panels and top cover, which will presumably make matters worse.

Fan SHIM our favourite pirates are selling makes temperature under control at all times. After installing it I haven't seen it going over 49ºC at any point. And - it is solderless installation - so no need to 'dedicate' PI to run with that particular shim.

Alternative (from my perspective) is what I've done for my son's Orange Pi - made a case with fan 1cm away from PCB constantly working extracting air. I suspect that (even being enclosed) it would keep temperature low enough...
