Choose fans designed specifically to push air through dense radiator fins.
High-performance thermal interface
Standard air coolers (even dual-tower flagships) reach their dissipation limit around 250W–280W. Once you exceed that, they become heat soakers rather than heat dissipators . This is the first reason standard cooling fails: physics.
Larger radiator surface areas allow fans to spin at lower, quieter RPMs while maintaining superior cooling efficiency compared to screaming air coolers.
