Overview
Fluid displacement through a dense 15.59 x 4.92 x 1.06 in (396 x 125 x 27 mm) aluminum radiator matrix defines the thermal strategy of this closed-loop cooling system, transferring thermal energy from processor IHS surfaces via a micro-skived copper cold plate. Operating completely independently of proprietary USB control hubs and background utility suites, the assembly interfaces directly with standard 4-pin motherboard headers. The variable-speed pump operates across a 1600 to 3150 RPM band at 12V DC, maintaining continuous coolant circulation through 17.72 in (450 mm) low-permeation rubber hoses shielded with braided nylon sleeving. By relying exclusively on motherboard BIOS logic and direct PWM signal regulation, the unit completely bypasses background software overhead, driver conflicts, and firmware vulnerabilities.
Airflow through the 2.05 in (52 mm) combined radiator assembly is driven by three 4.72 x 4.72 x 0.98 in (120 x 120 x 25 mm) RS120 fans utilizing Magnetic Dome fluid dynamic bearings. Rated for 300 to 2100 RPM, these fans generate static pressure spanning 0.2 to 4.15 mm H2O with volumetric airflow between 13.3 and 72.8 CFM, supporting Zero RPM mode at idle for completely silent low-load system states. Under sustained stress, the assembly maintains peak operating temperatures at 54.2°C while registering 36.0 dBA of acoustic output under maximum load. However, because the fan frames lack integrated rubber decoupling pads at their corner mounting tabs, mechanical vibration transfers into chassis sheet metal at rotational speeds exceeding 1200 RPM, generating a noticeable acoustic hum under aggressive cooling profiles.
Integration within modern enclosures is streamlined by daisy-chained fan cabling, pairing 1.97 in (50 mm) leads with 4.72 in (120 mm) jumper links alongside an included 23.62 in (600 mm) extension harness. Installation utilizes a tool-free bracket swap mechanism with pre-applied thermal compound and spring-loaded thumbscrews for Intel LGA 1851/1700 and AMD AM5/AM4 sockets. Practical trade-offs surface during orientation: the pump cap features a fixed, non-rotatable logo plate that restricts tubing orientation to the right side to keep branding upright. Furthermore, omitting legacy Intel LGA 1200 and 115x mounting hardware and spare thermal paste confines the package to current-generation platforms, while an extended 6-year warranty secures long-term operational durability.
