BeQuiet Dark Rock 3 Heatsink
May 24,2014 0 Comments
On the test bench today we have BeQuiet’s Dark Rock 3 heatsink; the “little brother” to the dual-tower Dark Rock Pro 3 CPU cooler Frostytech recently put through the thermal wringer. The Dark Rock 3 stands 159mm tall and weighs in at 976 grams. Built around six, 6mm diameter copper heatpipes and a large aluminum fin stack, the Dark Rock 3 is rated to heat loads up to 190W TDP by the manufacturer. Flipping the heatsink over, we find not exposed heatpipes, but a nice flat slab of copper to ensure good heat spreading when installed onto multi-core microprocessors. The copper base plate is plated with nickel for long term oxidation prevention.
As with BeQuiet’s previous heatsinks, the focus here is clearly on lower noise cooling. The 135mm PWM “Silent Wings” fan rotates at 1400-900RPM, moving upwards of 68CFM at a pressure of 2.1mm/H2O. BeQuiet’s Dark Rock 3 heatsink is compatible with Intel LGA2011/1366/115x/775 processors and AMD socket AM3/AM2/FM2/FM1/939/940/754 CPUs.
