Heat Sink Kit for Pi-Box Pro4
Consisting of: 2 aluminium heat blocks, screws and pads
Heatsink Kit
With the release of the Raspberry Pi4 the temperature of the processor under 100% usage has become an issue. When the processor gets too hot it throttles back which could compromise the application that the Pi is being used to perform.
As a solution we have developed a Heat Sinking Kit that consists of 2 aluminium blocks and adhesive pads that transfer the heat from the processor and the Ram chip to the aluminium carrier plate and then out to the enclosure, making the whole assembly a heat sink.
Temperature Test bench Test
We tested the Raspberry Pi4 running at 100% over a 10-minute period to register the temperature rise of the processor. The tests were performed with a bare board, one housed in a Raspberry Pi Foundation plastic enclosure, one in a Pi-Box Pro4 silver housing and one in a Pi-Box Pro4 black housing.
We saw a 19°C drop in operating temperature from 82°C in the bare board and plastic enclosure compared with the 63°C when housed in the Pi-Box Pro4 aluminium enclosure and heat kit.
