A Closer Look

Since the cooler uses dual aluminium fin stacks calling it hefty would be without a doubt quite accurate. Both fin stacks use the same design with the edges of the fins being arranged like a checkerboard, some stopping short and others sticking out creating said pattern. The edges of the fins are folded down which improves rigidity and keeps the spacing between them consistent. It should also result in more consistent air flow through the heatsink. Both towers also have cut away fins at the bottom for better compatibility with system memory.


The DeepCool AK620 Digital stands at a maximum height of 162 mm, making it likely to fit in most cases (always double-check, though). More importantly its size may pose some limitations on memory compatibility, however, DeepCool has taken steps to address this issue as effectively as possible. If performance lives up to its size it may prove a solid option for those opposed to AIO liquid coolers.


The digital display is held on top via four magnets. All six heatpipes are evenly spaced through both fin stacks. Meanwhile the base, while slightly convex, has a smooth nickel-plated finish however some milling marks are still visible.


The fans utilize a fluid dynamic bearing that has sealed corners, making for a clean look compared to traditional open-corner fans. When it comes to airflow, they can move up to 68.99 CFM and have an RPM range of 500–1850.
