Do you need additional cooling for your Raspberry Pi 4? Quiet, we have just what you need: Seeed Studio Blink Blink ICE Tower.
This heatsink is effective as a cooler CPU for PC but on a Raspberry Pi scale (not to mention miniature). The Blink Blink uses a single heatpipe to cool a relatively long aluminum bar which is, in turn, cooled by a small 40mm cooler. This small great device is able to keep the Raspberry Pi 4 SoC (and the 3 B / B + model) cool when performing intense tasks. Seeed says that this heatsink is capable of lowering 80 ° C to 40 ° C, which is not bad for less than $ 20.
As expected, this product is not easy to obtain in the region. However, if you are interested in seeing it, the Blink Blink ICE Tower is for sale through the Seeed Studio site.
