  • Even heat transfer on Intel CPUs via LGA 1700 and 1851 contact frame
  • Optimised Ryzen hotspot coverage with 5 mm offset mounting
  • VRM fan actively cools voltage converters
  • Single motherboard cable through integrated hose routing
  • Check compatibility for M.2 slot clearance on select boards

Dedicated power adapter for 360 mm AIO

This replacement power adapter is built for the ARCTIC Liquid Freezer III 360 all-in-one liquid cooler. It supplies the PWM-controlled pump and the integrated VRM fan that actively cools voltage converters on the motherboard. The unit is intended for builders who need a spare or replacement cable for this specific cooler model.

Replaces a lost or damaged original lead

The adapter restores power to the pump and VRM fan when the factory cable is missing, worn or accidentally cut during a rebuild. The jump is worth it when the cooler itself remains functional but the single visible cable that carries both pump and fan signals has failed. No other cooler or pump is supported by this part.

Limited to the Liquid Freezer III 360 platform

The connector and pin-out are unique to this cooler series, so the adapter cannot be used with other ARCTIC models or third-party AIOs. It also does not address the motherboard clearance issue where oversized M.2 heatsinks on the primary slot may interfere with the cooler's mounting frame. Buyers needing a different cable length or a universal pump power solution will not be served by this item.

Questions about this item

Will the 360 mm radiator and its mounting frame clear the LGA1700 and LGA1851 socket keep-out zones on my board?

The kit includes a dedicated contact frame for LGA1700 and LGA1851 that distributes pressure evenly across the CPU heatspreader, so the cold plate aligns with the socket keep-out zone without extra brackets.

Which cable do I plug into the motherboard header, and where does the VRM fan connect?

All radiator-fan PWM leads are integrated into the hose jacket, leaving a single 4-pin connector for the motherboard; the small VRM fan on the pump block has its own 4-pin lead that must be plugged into a second CPU-fan or system-fan header.

When should I plan to replace the pump-block VRM fan?

The VRM fan spins at up to 2001800 RPM; treat it as a wear item and expect to swap it after several years of continuous operation when bearing noise appears or RPM drops below spec.
