vs 12 on 120mm SeriesKey Features📐205.34 dm² — 420mm of Pure Copper Cooling
Wider 140.5mm body + 420mm length = the largest cooling area in its class. Outperforms 360mm radiators by over 70%. Designed for triple 140mm fans — more airflow at lower RPM for quieter operation.
💧16 Waterways — Wider Body, More Channels
Unlike the 12-channel 120mm series, the 140mm-class CRD42 packs 16 precision water channels. The 140.5mm width allows for an extra 4 channels — translating to more even coolant distribution and lower flow resistance.
🌬140mm Fan Optimized — Quieter, More Airflow
Three 140mm fans move significantly more air than three 120mm fans at the same noise level. The wider 140.5mm radiator body fully captures the larger fan sweep — no wasted airflow, no dead zones at edges.
🔩40mm Steel Frame — Reinforced Structure
Thick 40mm steel frame provides rigidity for the wider 140.5mm body. Copper fins + brass water chambers with flow division. High-temperature integrated welding for a leak-proof single-piece structure.
🛠Complete Screw Kit Included
Unlike basic radiator kits, the CRD42 ships with 12x M3x30 fan screws AND 12x M3x6 radiator mounting screws — enough for push-pull configuration plus case mounting, right out of the box.

- Screw Length:Must NOT exceed5mmpast fan surface. For push-pull 25mm fans, use the included M3 x 30mm screws. Punctured tubes NOT covered by warranty.
- Case Compatibility:Requires a case with native 420mm radiator support (3x140mm fan layout). Standard 360mm/120mm fan cases are NOT compatible. Measure your mounting area.
- Fan Compatibility:Designed for 140mm fans. 120mm fans will NOT align with mounting holes.
- Flush Before Use:Rinse with distilled water before first use to remove manufacturing residue.
