Slides from final night time’s discuss:

It’s inconceivable to have a Raspberry Pi Zero overheat until you overclock it. That’s why you don’t get any circumstances for it with followers or warmth sinks. The quad-core Raspberry Pi Zero 2 W, although, has the potential to take action. Listed here are some numbers:

  • Used official case with lid fitted: will increase SoC temperature +3 °C over free air
  • Take a look at – CPUBurn: https://github.com/pmylund/cpuburn
  • Examined 4, 3 and a pair of cores burning in 32-bit and 64-bit modes: time from idle to throttling (80 °C) measured
  • GPU overheat not examined.
line graph of cpu temperature against time. Temperature rises sharply from about 47 degrees C to 82 degrees C in around four minutes
All 4 cores burning, 64-bit mode: time to overheat = beneath 3½ minutes
line graph of cpu temperature against time. Temperature rises sharply from about 47 degrees C to 82 degrees C in just over four minutes
All 4 cores burning, 32-bit mode: time to overheat = simply over 4 minutes
line graph of cpu temperature against time. Temperature rises moderately from about 47 degrees C to 81 degrees C in around seven minutes
3 out of 4 cores burning, 64-bit mode: time to overheat = simply over 7 minutes
line graph of cpu temperature against time. Temperature rises slowly from about 47 degrees C to 81 degrees C in around ten minutes
3 out of 4 cores burning, 32-bit mode: time to overheat = 9½ minutes
line graph of cpu temperature against time. Temperature rises very slowly, reach 70 degrees C in 40 minutes and then only rising very slightly to about 73 degrees C in the entire run time of 3 hours 20 minutes
2 out of 4 cores burning, 32-bit mode: time to overheat = mainly by no means

Except you’re doing issues which may point out you ought to be utilizing an even bigger pc, a Raspberry Pi Zero 2 W gained’t overheat and doesn’t want any type of cooling. In the event you’re overclocking, properly … it’s your option to have cooling gear value greater than the pc it’s attempting to chill.
