![]() When running the board in the open air, without an enclosure, gluing a few passive heat-sinks on the black chips suffices. The Raspberry PI board has a harder time dissipating CPU chip generated heat. Raspberry PI 4 heat generationĪs it turns out, all the wonderful new processing power the quad-core 64-bit 1.5 GHz Cortex-A72 CPU offers, comes at a price. With this in mind, I touched the black Broadcom BCM2711 chip and thought “Ouch”. Since I didn’t connect the fan, I figured I should probably double-check that the chip doesn’t run too hot. After playing around with the Raspberry PI 4 through an SSH session and configuring it such that I can login with an SSH key, I opened the enclosure. When I saw the fan, I though to myself “Wait, why would I need a fan? Surely a fan is superfluous”. ![]() Included in the packaging of the enclosure were a few passive heat-sinks and a fan. To make the board more appealing to look at and to protect it, I placed the Raspberry PI 4 in plastic enclosure. After all, I wanted to verify the presence of the full 4 GB of RAM. ![]() The first command I ran was of course htop. With raised excitement levels, I booted the Raspberry PI 4 for the first time. All ready to setup the Raspberry PI 4 as a headless server. In a matter of minutes my micro SD-card contained the Raspbian Lite image. BackgroundĪfter my newly ordered Raspberry PI 4 board arrived in the mail, I dropped everything to take it for a spin. You can use these to build functionality into your own software programs for monitoring the Raspberry PI CPU temperature. ![]() This article presents you with code snippets in several programming languages for obtaining the Raspberry PI CPU temperature. Noticed that the Raspberry PI 4 runs a bit hotter than previous models? That is the unfortunate side effect of packing an increased amount of processing power in the same small board form factor. ![]()
