Pacific MX1 Plus water block

The Thermaltake Pacific MX1 Plus is a CPU water block designed for custom liquid-cooling loops. It fits Intel sockets from LGA 775 through LGA 1700 and AMD sockets from AM2 through AM5. The block uses a nickel-plated copper base with dense micro fins to transfer heat from the processor into the coolant. Twelve addressable LEDs shine through a vacuum-metalised mirror top cover.

Upgrade from stock air coolers

Builders moving from factory air coolers or basic all-in-one units gain a component built for open-loop thermal capacity. The jump is worth it when the loop already includes a pump, reservoir and radiators sized for the target heat load. The integrated temperature sensor feeds real-time coolant data to TT RGB Plus software for lighting reactions tied to thermal conditions.

Fits standard G 1/4 loop fittings

The block accepts G 1/4 threads and draws 2.4 W at 5 V through a 4-pin Molex connector. A 9-pin USB 2.0 header links the onboard controller to the motherboard for software control. The 93.4 mm square footprint and 52.2 mm height require clearance around the socket keep-out zone. LGA 1700 mounting brackets are not included and must be sourced separately.

Questions about this item

Does the 93.4 mm square footprint and G 1/4" thread spacing fit my loop?

The block measures 93.4 mm by 93.4 mm and uses standard G 1/4" threads, so it fits most custom loops with matching fittings and clearance.

How do I connect the 4‑pin Molex power and 9‑pin USB 2.0 header without missing a step?

Plug the Molex connector into a PSU rail for the 5 V / 2.4 W supply, then attach the 9‑pin USB cable to a motherboard header so the temperature sensor and 12 LEDs appear in TT RGB Plus software.

Will the nickel‑plated copper base or the 12 addressable LEDs need replacement down the road?

The copper base is nickel plated for corrosion resistance and the 12 LEDs are sealed under the mirror top; neither is user‑serviceable, so no routine replacement is expected.
