ASRock Challenger 240 Digital AIO Liquid CPU Cooler 240mm
The ASRock Challenger 240 Digital AIO Liquid CPU Cooler is built for gamers who want real-time temperature monitoring and synchronized RGB lighting without the complexity. A 3-inch digital display shows live CPU temperature, frequency and pump speed, while automotive-grade components and a 3-phase pump deliver stable cooling across Intel and AMD platforms.
Why this product
3-inch digital display with live monitoring
Shows real-time CPU temperature, frequency and pump speed directly on the water block. Install the Challenger Driver to adjust display mode switching and view system information.
0dB silent mode under low load
Fans stop completely when the CPU is cool, eliminating noise and extending component lifespan during idle or light gaming.
Full RGB ecosystem support
Works with ASRock Polychrome SYNC for motherboard synchronization and SignalRGB for game-reactive effects and system-wide lighting control.
Automotive-grade pump and tubing
3-phase 6-slot 4-pole motor with IIR+EPDM core and braided sleeve resists coolant evaporation and deformation for extended durability.
Pre-installed fans and routed cables
Radiator ships ready to mount with neatly routed cables, cutting installation time and eliminating cable clutter.

Best for
- Gamers wanting live temperature monitoring without software
- RGB-synchronized builds using ASRock or SignalRGB-capable systems
- Builders prioritizing quiet operation during light loads
- Users planning to keep the cooler for 6+ years
Trade-offs
- High-end workstation CPUs exceeding 270W TDP will need a larger cooler.
- Non-ASRock motherboard users who want plug-and-play Polychrome SYNC will need to use SignalRGB software instead.
- Silent-PC builders who need noise below 31 dB(A) at all loads; maximum fan noise reaches this level under heavy cooling demand.
