Pacific W1 Copper CPU Water Block

The Thermaltake Pacific W1 is a nickel-plated copper water block built for custom-loop builders who want a compact cold plate with broad socket support. Its 0.15 mm microfin structure increases surface area for efficient heat transfer from mainstream and enthusiast CPUs.

Universal Mounting and G 1/4 Ports

The package includes brackets and hardware for Intel sockets from LGA 775 through LGA 2066 plus AMD platforms from AM2 to FM2+. Two G 1/4 threaded ports give you ideal spacing for standard or rotary fittings so tubing routes cleanly in tight builds.

Compact Dimensions and Microfin Headroom

At 16 mm long, 54 mm wide and 60 mm high the block fits confined spaces while the fine internal fins handle typical overclocking loads. Extreme multi-die processors or very high heat flux chips may exceed what this single-block design can dissipate.
