Keeping the gaming computer cool, the Kolink Unity Arena features extensive support for both air cooling and water cooling hardware. The four pre-installed fans are positioned three on the side, with reverse blade design to provide intake, and the last one is placed at the back for exhaust. Additionally, there is plenty of ventilation throughout the case to facilitate natural airflow.
Both the side and rear panels hold alternative fan configurations, with more support provided at the top and bottom. On the side, you can instead mount up to three 140mm fans or a 360mm radiator. At the back, the other configurations are either a 140mm fan or your choice of a 120mm or 140mm radiator. The top panel offers the same support as the side, up to three 120mm or 140mm fans or a 360mm radiator, while the bottom can accommodate two 120mm fans or a 240mm radiator.
