Review on 🚀 High Performance Youyeetoo Rock PI 4B V1.4 SBC with Raspberry Pi Display Compatibility (RK3399 ARM Cortex Six Core CPU, 32G eMMC) by Martin Masaniai

I received exactly what was described after searching to no avail for a heatsink for my 4B which was able to be delivered in a very short time. Buying here costs three times more than from a Chinese supplier. Let me save you time and money: the 4C heatsink is completely mechanically incompatible with the 4B board. I took mine to the milling machine to make something reasonably fitting while waiting for the part to arrive on its slow boat.
