PC CPU Cooling Fan Tunnel - For 12cm Fan, 6.5cm Height

This PC CPU cooling fan tunnel is designed to improve airflow in your computer system by drawing in colder air from outside the case. It is optimised for use with a standard 12 cm fan and is ideally suited for ATX and mATX cases, including models such as the Asus Prime AP201. Measuring 120x120 mm with a height of 65 mm, the tunnel creates a direct channel for cool air to your CPU cooler, which is particularly beneficial for large tower CPU coolers such as the Thermalright Peerless Assassin 120. Installation is straightforward as the tunnel uses the same mounting holes as a typical 12 cm PC fan, ensuring easy and stable attachment for optimal cooling.
