Compatibility and installation
- Confirm 240 mm radiator space and measure radiator-plus-fan stack; top/front mounting can conflict with memory, VRM heatsinks, GPU, or side panel.
- Follow Cooler Master’s exact pump/fan/lighting wiring and socket mounting manual; use the included platform-specific bracket.
- Do not power pump or fans from an under-rated header; check the manual and host header/controller current budget.
Service notes
Do not open the sealed AIO loop. Inspect tubes, fittings, radiator and pump for leaks, damage, or abnormal noise; stop use and replace the assembly if a leak or pump failure is suspected. Clean radiator fins without bending them.
