Pacific C240 copper radiator

The Pacific C240 is a 240 mm copper radiator built for custom liquid-cooling loops. Its 27 mm thick core uses high-density fins and brass tanks to suit enthusiasts who want reliable heat dissipation in a slim form factor.

17 FPI density and 12 flat tubes

Seventeen fins per inch and twelve flat tubes give strong thermal capacity for typical dual-fan airflow. Performance scales with fan speed, and the slim profile leaves headroom for tight chassis layouts where thicker radiators would not fit.

Tt LCS certified compatibility

Tt LCS certification confirms fitment with Thermaltake liquid-cooling chassis and standard G1/4 fittings. The radiator upgrades older aluminium loops to full copper construction, and the jump is worthwhile when corrosion resistance and maximum conductivity are priorities.
