The Challenger White 240 Digital is an all-in-one liquid cooler with a 277 mm aluminum radiator and a copper cold plate. It fits AMD Socket AM4, AM5 and Intel LGA 1700, LGA 1851 platforms. A 3-inch segment LED display on the pump block shows CPU temperature, frequency and pump speed in real time.

Pump runs 1200 to 3200 RPM fans peak at 2100 RPM

The 3-phase 6-slot 4-pole pump operates between 1200 and 3200 RPM for strong flow with low noise. Two 120 mm ARGB fans deliver up to 62.6 CFM airflow at a maximum of 31 dB(A). Fan speed ranges from zero to 2100 RPM, allowing near-silent idle and ample airflow under load.

450 mm tubes white ARGB fans Polychrome SYNC

Tubing length is 450 mm, giving flexibility for mid-tower and larger cases. The white finish extends to the block, fans and radiator for a unified look. ARGB lighting syncs via Polychrome SYNC and SignalRGB. An integrated ARGB hub on the block simplifies cable routing for additional lighting strips.

Questions about this item

How do I mount the block on an AMD AM5 socket, and what step is often missed?

Use the supplied AM5 bracket, apply paste, and tighten the four screws in a cross pattern; the step often missed is plugging the block's USB cable into a motherboard header so the 3" display and ARGB can be controlled.

Which part will need replacement first, and how can I tell?

The two 120 mm fans rated at 2100 RPM and 31 dB(A) are the wear items; listen for rising noise or dropping airflow below 62.6 CFM as signs the bearings are ageing.

What thermal limit appears first during a long, heavy workload?

The 277 mm aluminium radiator with 27 mm thickness and 450 mm tubes can only dissipate so much heat; once coolant temperature stabilises, CPU temperature stops falling even if the pump runs at 3200 RPM.
