Pure copper Water Block base maximizes cooling performance and gold plating prevents galvanic corrosion. Intel Pentium 4 (Socket 775/478), AMD Duron/Athlon/Athlon XP/Sempron (Socket 462), and AMD Sempron/AMD64 (Socket 775/939/940) compatible design for broad compatibility. Two types of fittings are provided for use with various kinds of tubes. * Notice This CPU water block is a component for water cooling systems for CPUs and cannot be used independently. It must be used with a water cooling system like ZALMAN’S RESERATOR Series and a system supporting following tub sizes: Compatible Tubes (Outer x Inner) : 13 x 10mm, 13 x 9mm, 12 x 8mm, 11 x 8mm, 10 x 8mm

Intel Pentium 4 (Socket 775/478) Supports all Speeds AMD Duron/Athlon/Athlon XP/Sempron (Socket 462) AMD Sempron/AMD64 (Socket 754/939/940)

Compatible if no motherboard components physically interfere with ZM-WB3 Gold's clip (Mainboards not complying with Intel's '10.2mm motherboard component height restriction' should check for interference.)   Compatible if there are four heatsink mounting holes around the socket.   All CPUs conforming to Socket 754/939/940 platform

Zalman affixes a Computer Noise Prevention System (CNPS) mark to all components used for noiseless computers.

Test the product for leakage before installation away from the system first. After no leakage is confirmed, proceed with installation and use. To prevent corrosion, only use coolant that has been approved for computer water-cooling. Only use coolant tubes with compatible specifications. The exposed core of a Socket 462 CPU can be damaged due to improper installation. Please read the 'Installation' section thoroughly before installing. Tubes that are not of 12 x 8mm should be used with spare fittings. If interference with components of the mother board is encountered, do not install this product.
