Enhanced Heatpipe Direct Touch: With the Rev.4 Tranquillo, the CPU surface is directly touching the heatpipes, so heat is transferred much more quickly than of a typical heatsink with heatpipes attached to a copper base-plate.
Stack Fin Soldering: Unlike the other heatsinks, the Rev.4 Tranquillo features a greatly improved technology, Stack Fin Soldering, which assures the most efficient thermal contact between heatpipes and fins thanks to the special solder joints.
Nickel Plating: Poor quality of the fin surface often results in dirty or corroded fins which worsen heat conduction and limit the heatsink thermal performance considerably.
Intelligent GELID PWM: An improved 120mm fan with the intelligent GELID PWM (Pulse Width Module) control compliments the heatsink.
