Heatsink Casefor Raspberry Pi4B

The Active Heatsink Case of Raspberry pi 4B not only can provide efficient heat dissipation,but also can connect various hats through extra GPIO connector and POE pin connector,such as POE HAT,etc.Two versions of the cooling fan interface are available,USB and 2pin DuPont.Cooling effect Burn-in Test:
Raspberry pi 4B uses TYPE-C port to power.
sysbench threads=4 CPU-max to test.
the test environment temperature is 25 degrees Celsius,and the test period is about 6 hours later.
Use vcgencmd measure_temp to view the pi temperature,the temperature can be kept stably between 52-53 degrees Celsius.Feature:
1. Slotted to avoid wifi/Bluetooth antenna and does not affect the wifi/Bluetooth signal transmission.
2. Six Builtin thermal column,each chip of Pi 4B can dissipate heat in time,making heat dissipation more effective
3. insulated Thermal Silicone Pad,quickly transfer heat to Cooling Base.
4. Quiet Turbo Blower Fan guides Air flow through the entire Base,and the air flow without blocking heat dissipation effect is better.
5. Overall heat dissipation aluminum alloy shell carved by CNC not only can offer well heat dissipation, but also can give you extra protection of Raspberry Pi.
6. The Unique microSD card protection structure to prevent accidental damage of protruding microSD protruding parts):
Upper half part: Length 69.5mm x Width 56mm x Thickness 16mm
Down half part::Length 91.5mm x Wideth 56mm x Thickness 16mmItem Included:
Raspberry pi 4B active Heatsink Case x1
Insulated Thermal Silicone Pad x7
M2.5x9+6 Hexagonal Copper Column(for Pi Original factory POE HAT) x4
