The for Active Cooler provides an alternative cooling solution for users who wish to use their for 5 under sustained without a case (but you might want to add one of our fancy Active Cooler covers for protection!) The Active Cooler combines a large heatsink with a high-quality variable-speed blower fan, powered and controlled via the fan connector on the for 5, attached to the board via sprung pins into the dedicated pair of mounting holes. As the heat from the Pi 5 CPU spreads across the heatsink body and fins, the blower fan pushes cool air over them to keep your for 5 running at optimal thermal levels. The cooler uses thermal pads to create a solid thermal connection with the for 5. The fan is software-controlled, allowing it to remain off (and therefore silent) until temperatures reach the specified threshold.<br><br>Due to different batches, there may be differences in product printed text, which not affect use Colour:As Shown Material:Aluminum Alloy<br><br>Package Contents: 1 x Cooler with Fan<br><br>Only the above package content, other products are not included.
