The DT621 Series delivers dual-tower cooling performance in a compact footprint designed for smaller systems. With six heat pipes and a mini dual-tower layout, it offers the cooling capability of a full dual-tower cooler while staying close to the size of a typical single-tower design.

The included 120 30 mm fan is thicker than a standard 25 mm fan, helping generate higher airflow and air pressure at the same RPM and noise level. Even with a single fan, the DT621 moves heat quickly and efficiently while keeping noise under control.

A fully coated heatsink and clean modern top cover give the cooler a unified look inside the system. The coating also helps protect the heat pipes and fins from oxidation for longer-lasting durability.

At just 159 mm tall, the DT621 is designed to fit most compact and small-form-factor cases while delivering the heat dissipation strength of a dual-tower cooler.

The compact structure is designed to avoid interference with RAM modules and motherboard VRM heatsinks, helping improve compatibility across a wide range of modern system configurations.

The DT621 includes a newly designed 120 30 mm fan that is thicker than standard 25 mm fans, helping generate higher air pressure and airflow while keeping noise levels under control.

Supports multiple mainstream models. Recommended processors include:

Clean Finish for a Unified Build

The DT621 features a fully coated finish that helps prevent oxidation on the heat pipes and fins. Paired with a newly designed top cover, it blends cleanly into the system while improving the overall visual appeal.
