Raspberry Pi Dual-fan Cooling Expansion Board With LED Compatible With All Types Of Raspberry Pi Pins

The Raspberry Pi dual-fan cooling expansion board is compatible with all types of Raspberry Pi pins, which is able to dissipate heat without affecting its development and use, and all GPIO are drawn out with clearly-marked pins. This dual-fan adopts active cooling installation, whose cooling effect is better than the passive one. Besides, LED on the board and fans are controlled separately, and the LED is welded on the back so that it will not glare when opened at night.
In order for a more effective heat dissipation, hexagonal copper pillars are used for heightening the distance between the cooling board and the chip to enlarge its pressure zone. In common, it takes five minutes for the fan to reach a stable working state, yet you don’t need to worry about its efficiency at all for the temperature of Raspberry Pi rises gradually after being turned on.
