Pure copper base ensures excellent heat dissipation, and anodized aluminum top prevents corrosion. Intel Pentium 4 (Socket 478), AMD Athlon/Duron/Athlon XP (Socket 462), Athlon 64 (Socket 754) compatible design for borad compatibility. Three types of compression fitting are offered for use with water tubes (8 x 10mm, 8 x 11mm,10 x 13mm) * 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 such as ZALMAN's RESERATOR 1/Plus Water Cooling System.   This CPU water block can be compatible with socket 462 motherboards that have cooler mounting holes around the CPU socket.

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

Compatible if no motherboard components physically interfere with ZM-WB2 Gold's clip (Mainboards not complying with Intel's "10.2mm motherboard component height restriction" should check for interference. If interference occurs, the excess portion of the clip that interferes can be cut off to make it compatible.)   1. Compatible if there is no motherboard component higher than 15mm in height (usually capacitors) where the clip is to be located (If interference occurs, the excess portion of the clip that interferes can be cut off to make it compatible.) 2. Compatible if there are four heatsink mounting holes around the socket.
