Heating and cooling Raspberry Pi 5
Some cool measurements on the ‘hot’ (as in interesting) Raspberry Pi 5
From the article provided by Raspberry Pi:
Every time a new Raspberry Pi is released, there are mutterings around thermal control of the new board. People want to know whether it’s necessary, and if so, what you’ll need to do to make it happen. This time around, with the release of Raspberry Pi 5, we’re introducing two new official hardware solutions for cooling.
For normal usage of your Raspberry Pi, adding cooling is entirely optional. The idle performance of a Raspberry Pi 4 and a Raspberry Pi 5 is about the same, and under typical loads Raspberry Pi 5 will run cooler than a similarly loaded Raspberry Pi 4. However, a heavy continuous load will mean that the board could potentially go into thermal throttling. Throttling happens as there are software controls to limit CPU speeds if things get start to get too toasty. Although, even when fully throttled, a Raspberry Pi 5 is still going to run faster than a Raspberry Pi 4!
But data makes everything better, so I decided to grab some early production hardware and run some tests to help you make up your own mind whether you’re going to need to cool your own Raspberry Pi 5.
From the conclusion:
When deciding on a cooling solution you should consider what sort of use you’re going to put your Raspberry Pi 5 to, and make a decision on cooling based on that, rather than just arbitrarily adding cooling. Because for a lot of day-to-day use cases, it’s not going to be needed.
Cooling of any type isn’t mandatory, no harm will come to your Raspberry Pi if it’s left uncooled — and even while throttling under heavy load, a Raspberry Pi 5 is still faster than an unthrottled Raspberry Pi 4.
