## Long description

Thermaltake Pacific W4 Plus is a CPU water block made from copper with a PMMA top cover and a black finish. Measuring 93.4 × 93.4 × 22 mm and weighing 0.67 kg, it is designed for custom liquid cooling loops and high-performance thermal management. The block uses 1/4" G1/4-compatible threaded ports for coolant connections and mounts to modern CPU sockets using a universal, tool-free mounting mechanism. The copper base has a mirror-finish mating surface for direct contact with the CPU and an internal micro-channel fin structure to promote efficient heat transfer.
Advantages
The internal fin construction (0.15 mm micro-channels) and a polished copper contact surface provide efficient heat transfer from CPU to coolant while the PMMA cover allows visual inspection of coolant flow. Integrated RGB lighting with 12 addressable LEDs and a 16.8 million color LED ring is controllable via the TT RGB PLUS system and offers multiple lighting modes. A digital lighting controller with DIP switches is included for device addressing, and the block is compatible with common G1/4 fittings for broad system compatibility.
Suitable for
Custom PC liquid cooling loops for desktop CPUs
High-performance workstations and gaming rigs requiring improved thermal management
Builds where visual lighting and visible coolant flow are desired

Usage recommendations
Use a corrosion-inhibiting coolant and follow recommended loop filling and bleeding procedures. Periodically inspect fittings and hoses for leaks, and clean the mating surface and replace thermal interface material when removing or re-installing the block to maintain optimal thermal performance.
