My PI is too cool. It freezes. I have playing with a PI Zero W over the last weeks. At first everything worked as expected. But now it developed some strange "hangings" I cannot explain. It kinda randomly freezes in time for a few minutes every now and then. Sometimes it takes several minutes to ssh into it. Sometimes, the terminal just freezes for several minutes. Neither top nor iostat seem to show any elevated act…
Thermal engineer here. There absolutely no need to use fan cooling, humongous heatsinks or harebrained temperature controller schemes to cool the raspberry pi 4. All that is needed is a small heatsink to slightly decrease the thermal resistance to ambient air, to stay below the thermal throttling threshold. Anything more complicated than that is a pointless exercise in pointlessness.
Earlier quoted context omitted.
I kind of agree. I think in most situations, a Pi is going to sit idle most of the time, so it won't need active cooling.
What if I want to use pi 4 as a building farm? Especially now with the 8gb version out, it seems to be suitable for building haskell programms
Anyone has links to similar articles with regards to either - SD card reliability - techniques for reliably using what we have ? Given that people are using these for all kinds of stuff there must be some advanced techniques being used (or some basic I have missed).
I've been running a raspberry 3 with a cheap sandisk sd card for years now without any SD Card issues. It runs a DNS based ad-blocker and a vpn. I am logging everything to ram instead of writing it to the card and that's about it. I never encountered any issue with SD Card reliability, despite me sometimes just pulling the plug instead of properly shutting it down. Here is a simple guide: https://raspberrypi.stackexc…

That makes me think a lot before choosing passive or active cooling.
The Flirc case-as-heatsink one seems good tho, and on-line with your statement
