Overview
Pushing 6.1 mmH2O of static pressure through dense liquid cooling radiators requires exceptional structural rigidity, which is achieved through an all-aluminum frame expanded to 1.18 in (30 mm) in depth rather than the conventional 0.98 in (25 mm) standard. This extra 0.20 in (5 mm) of rotor and housing depth allows for steeper blade sweep and increased air displacement, generating up to 76.9 CFM of airflow at an upper limit of 2,500 RPM. Driven by a three-phase motor coupled to double ball bearings, the mechanical assembly is engineered for heavy continuous workloads with a verified mean time to failure (MTTF) of 200,000 hours.
Power delivery and speed control rely on standard 4-pin PWM signaling, augmented by native daisy-chain cabling that simplifies multi-fan deployment across multi-radiator loops and front intake brackets. The all-metal outer housing acts as a rigid anchor, eliminating frame deformation when torqued down against radiator screw channels, while eschewing all RGB circuitry in favor of a strictly utilitarian industrial aesthetic.
In practical deployment, the extended 4.72 x 4.72 x 1.18 in (120 x 120 x 30 mm) footprint demands careful verification of chassis clearances, particularly around motherboard VRM heatsinks and top-mounted liquid coolers in compact enclosures. While operating at the full 2,500 RPM velocity introduces the expected mechanical acoustic presence associated with dual ball bearing assemblies, the high pressure ceiling ensures superior fluid dynamics through restrictive dust filters and thick radiator fin matrices where standard-depth fans lose throughput.
