The Raspberry Pi 4 needs a fan

Indeed, the fan shim is insanely cool and I just bought one of these the moment that it was back in stock together with my Raspberry Pi 4. It also works on the Pi 3 and 2. Here's the link if anyone's interested: https://shop.pimoroni.com/products/fan-shim

Glad you like it! We think it's the best solution for cooling any model of Raspberry Pi that's available.

Even the previous-gen Pis would easily throttle under load without a heat sink (although usually installing a decent heat sink was enough to resolve the problem, assuming decent airflow). As the article notes, the heat was mainly from the SoC in the past. The Pi 4 is on a whole different level indeed. I imagine the logic here is the same as with many other Pi accessories: if you need it, you'll buy it or get it as pa…

That’s just it, though. The official Pi power supply is adequate and good for powering the Pi in any condition, but the case is a far cry from adequate. At best, it just toasts everything inside more evenly, at worst it contributes to throttling because now the heat from every other part of the Pi forms a hot thermal blanket over the CPU. I’m amazed they didn’t at least add a few passive ventilation holes or slots, s…

That link 404s for me unfortunately.

Quote: the metal casing helps spread that heat around It does, to a degree. But that is absolutely not what we are seeing in that IR picture. Shiny bare metal is a mirror at the wavelengths that thermal camera uses. So what you see on thermal image where wifi-module shield and CPU are is reflection of ambient (room) where this picture was taken. Try waving your hand around, you'll see it reflecting there too. To meas…

> If you run computing hardware at its thermal capacity for long periods of time, this will cause more wear on the parts than if they are run well inside their limits. How true is this actually? Personal anecdote is an I5-2500K overclocked to 4.6ghz with budget aftermarket cooler (its at 4.6ghz constantly regardless of load). It's been running 24/7 in my desktop since 2011. When will it fail? I see these disclaimers…

Last time I checked, a consumer grade CPU has expected lifespan of 20-30 years, so your CPU is still in its young adult years
