Under load with YAFFplayer, the temperature reached 73☌. As you can see on the following screenshot, the four cores are utilized and all clock speeds are pushed to the max.ħ4☌ is a nice temperature for a Raspberry Pi 4 without heat sink.Īt idle, the heat sinks have an effect by removing 3☌. I played a 1920×1080 video until the temperature reached a maximum value of 74☌. YAFFplayer is nice stress test tool because it has a multi-threaded video decoder (so the four cores of the RPi 4 CPU are loaded) and video is displayed using OpenGL. To stress test the Raspberry Pi 4, I used YAFFplayer. Since an up to date version of the firmware is very important (see this article), I also checked the firmware version with the following command: The ambient temperature in the room was 21☌.
The temperature has been measured with GL-Z as well as with RaspiOS built-in widget.
Let’s see the processor temperature of the new RPi4 8GB with and withtout those heat sinks.ġ – Raspberry Pi 4 8GB without heat sinksĪt idle (with the latest Raspberry Pi OS), the temperature of the processor was 55☌. I got the new Raspberry Pi 4 8GB few weeks ago, and I took at the same time a kit of four heat sinks designed for the RPi 4.
