The Phanteks PH-TC14S heatsink stands 161mm tall and weighs 740grams. It's built around six 6mm diameter heatpipes, a chunky nickel plated copper heatspreader and two black painted aluminum cooling fin towers, each 19mm wide. At the center of the heatsink is a 140mm PWM fan that operates at 1600-500RPM, producing upwards of 47dBA according to our real world noise measurements. The fan itself moves 68CFM at 1.62mmH2O, according to manufacturer specs. he aluminum fins of the Phanteks PH-TC14S heatsink have been painted black for aesthetic reasons, not anodized as several novice reviews have mistakenly reported. A coating of paint on a heat transfer surface is not ideal as it insulates the aluminum fins from the surrounding air mass to some degree.
