Hardware Labs Black Ice GT Stealth 420mm

Two-pass U-flow Tank configuration. Custom MaxFin™ 25 micron Copper Splitter Fin Configuration utilizing 45% thinner fin material yielding up to 50% less pressure drop even with twice the fin density. Unique fin configuration eliminates intra-louver accumulation of dust particles for trouble free operation. Unprecedented Ultra-high 30 FPI (Fins Per Inch) fin density providing dramatically increased heat transfer surface area. Custom low-profile 19.0 x 1.2mm MaxFlow™ tubes with 15% more waterside surface area and 60% frontal area reduction for superior low air-resistance aerodynamics and lower internal flow requirements. Yields up to 35% more heat exchange capacity than the Black Ice® Pro III in both Stealth or Performance modes. Achieves Black Ice® Xtreme level performance in stealth mode (low-noise/low-airflow conditions). First computer radiator configured and optimized for triple 140mm fans. M4 Threaded Screw Holes for easier mounting and greater adaptability. Now standard G 1/4" female threaded fittings. Full high-temper brass structural construction for weight reduction and superior corrosion resistance. Uses 100% Non-corrosive water-soluble fluxing process. Lead-free construction for environmental protection and RoHS compliance. Full electrostatic polyurethane painting finish for uniform coating with high temperature curing for increased finish durability. Renowned Black Ice® quality. Patent Pending Design.
