Unlit 360 mm AIO for clean builds

The ASRock Challenger Pure 360 is an all-in-one liquid cooler with a 394 mm radiator, three 120 mm PWM fans and a copper cold plate. It fits AMD Socket AM4, AM5 and Intel LGA 1700, 1851 platforms. The block measures 85 x 84.1 x 53.5 mm and the fans run at 0 to 1800 RPM with a maximum airflow of 53.9 CFM and 27 dB(A) noise. No LEDs are present on the block or fans.

Replaces air coolers when silence matters

Moving from a tower air cooler to this 360 mm loop is worthwhile when the CPU sustains high loads and case airflow is limited. The pump operates at 0 to 1800 RPM with a 3-phase, 6-slot, 4-pole motor designed for low torque ripple. Radiator thickness is 27 mm and tube length is 450 mm, allowing flexible routing without sharp bends that restrict flow.

Fits standard three-fan mounts

The radiator occupies three 120 mm fan slots measuring 394 x 119.6 x 27 mm, so the case must support that length and thickness. Fan connectors are 4-pin PWM for motherboard speed control. The compact water block leaves clearance around the CPU socket for tall memory modules and large VRM heatsinks. IIR plus EPDM tubing resists permeation for long-term reliability.

Questions about this item

What case clearance is needed for the 394 mm radiator and 27 mm thickness?

The radiator measures 394 mm long, 119.6 mm wide and 27 mm thick, so the case must provide a 360 mm three-fan mounting area with at least 27 mm depth plus fan thickness.

How do I connect the pump and three 120 mm fans to the motherboard?

The pump uses a 3-phase 4-pole motor running up to 1800 RPM; each fan has a PWM 4-pin connector and also runs up to 1800 RPM, so plug the pump into the CPU_FAN header and the fans into SYS_FAN headers.

When should the IIR + EPDM tubes and copper cold plate be inspected or replaced?

The 450 mm tubes are IIR plus EPDM rubber and the cold plate is precision-machined copper; check for permeation or corrosion every 2 to 3 years and replace if coolant loss or temperature rise appears.
