1300W ATX liquid cooler

The KHACHIMO 2M3400K is a 1300W ATX liquid cooler designed for high-performance desktop builds that demand substantial thermal headroom. It suits enthusiasts assembling workstations or gaming rigs with power-hungry components.

Thermals noise and power

An 80 PLUS Gold certified design delivers high efficiency, lowering power consumption and reducing waste heat under typical loads. Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion minimises coil whine and supports modern standby sleep states.

Modern standby and zero rpm benefits

Modern Standby compatibility enables extremely fast wake-from-sleep transitions while maintaining better low-load efficiency. The combined effect of zero fan noise and reduced coil whine creates a quieter environment during everyday workloads. These features change the daily experience by keeping the system responsive and unobtrusive when idle or lightly loaded.

Questions about this item

How do I install the KHACHIMO 2M3400K 1300W liquid cooler and what step is often missed?

Mount the radiator, attach the pump block to the CPU with the supplied brackets, connect the pump and fan headers, then enable Modern Standby in the BIOS for fast wake-from-sleep.

What maintenance will the 2M3400K need over time?

The sealed loop requires no coolant refills; only clean radiator fins and verify the Zero RPM fan spins up under load.

What limit appears first during sustained 1300W operation?

The 80 PLUS Gold efficiency target is the first constraint; beyond it, heat and fan noise rise sharply.
