GAMDIAS Boreas E2-51D 120mm CPU Air Cooler ( Black )

The Gamdias Boreas E2-51D is a single-tower 120mm CPU air cooler finished in matte black, designed for mainstream desktop builds that demand both functional cooling and real-time thermal monitoring. A standout feature is the integrated crystal-clear digital display mounted at the top of the heatsink tower, allowing users to keep an eye on CPU temperatures at a glance without relying on software overlays or opening a monitoring application. At the core of the cooler's thermal solution are five copper heat pipes arranged in a direct-contact configuration with the CPU integrated heat spreader. This layout eliminates an intermediate copper base layer and transfers heat directly from the IHS surface into the heat pipes, improving thermal conductivity at the source. The heat pipes channel warmth into a dense stack of aluminum fins that form the main tower body, giving the cooler a compact 120 × 75 × 159 mm overall footprint — low enough to fit comfortably inside most mid-tower enclosures. Cooling airflow is handled by a single 120 × 120 × 25 mm hydraulic-bearing PWM fan. The PWM signal allows the motherboard to ramp fan speed between 800 RPM at near-silent idle loads and 1800 RPM when the system needs maximum heat evacuation. At peak speed the fan moves up to 72.94 CFM of air through the fin stack while generating 2.63 mmH2O of static pressure — sufficient for dense fin arrays. Noise output ranges from 10 dBA at low RPM to 32 dBA at full speed, making the cooler suitable for quiet workstation environments. The fan connects via a standard 4-pin PWM header, while a 9-pin USB header serves the digital display module. The Boreas E2-51D supports GAMDIAS's ZEUS CAST software, which extends display customisation options through Windows. DIMM slot clearance is maintained by the cooler's narrow tower profile, so memory upgrades remain straightforward on both Intel and AMD platforms.
