Hello,

Since the first day of setting up my Homey 2023, I have noticed that the temperature fluctuates between 58 degrees and 65 degrees. Could you tell me if you are experiencing similar results at your place? I have the impression that it is heating up a lot.

Thank you.

There is dedicated thread,where this is being discussed and some DIY solutions applied. However quick answer - yes, unfortunately it’s normal, critical is 85 °C

Okay, thank you. I thought there was an issue, and I was ready to get some fans. So, if it’s normal, I assume the designers have conducted extensive tests to prevent any component degradation, and there’s no need to be alarmed.

Lower temperature is always better. Anyway, you can read more on CM4 temperature here - [https://datasheets.raspberrypi.com/cm4/cm4-datasheet.pdf](https://datasheets.raspberrypi.com/cm4/cm4-datasheet.pdf)

```auto
The BCM2711 will reduce the clock rate to try and keep its internal temperature below 85°C. So in high ambient
temperatures it is possible that the clock will also be automatically throttled back. If the BCM2711 is unable to lower its
internal clocks enough to bring the temperature down, its case temperature will rise above 85°C. It is important that any
thermal solution chosen keeps the ambient temperature for the other silicon devices on the CM4 within the operating
temperature range.
Operating temperature range: -20°C - +85°C non-condensing. NB Optimal RF wireless performance is between -20°C and
+75°C.
