If you are interested in purchasing the new Raspberry Pi 4 ICE Tower processor cooling fan to help bring your mini PCs temperature down a little. You may be interested in a new performance analysis post published by the team over at the CNX Software website. Providing plenty of data on the add-on cooling system that is now available to purchase and supports Raspberry Pi 4B/3B+/3B SBC’s
Created by S2Pi and specifically designed for the Raspberry Pi mini PC range, the latest Raspberry Pi 4 will definitely benefit from a cooling fan due to its higher temperature range while under load and daily use.
“With the heatsink the Raspberry Pi 4 will idle at around 37°C, and tops at 46.2°C when all four cores are used (7-zip multi-threaded compression/decompression). Note: room temperature was 27-28°C. Compare this to running the same benchmark without any heatsink at all, although at 28°C room temperature. The board would idle at around 65°C going up to well above 80°C, and frequently throttling, as Broadcom BCM2711 processor will throttle if the temperature reaches 85°C. So the fansink clearly does the job, but I hear some say they did not buy a Raspberry Pi 4 to install a noisy fan on top, and it also increases power consumption (by 0.4W).”
