Akasa's Nero AK-967 heatsink is based on the popular "heatpipe direct touch" technique, and like so many CPU coolers, for today's class of heatspreader capped processors it's the only way to go! The Akasa Nero AK-967 heatsink FrostyTech is reviewing today is equipped with vibration absorbing rubber fan posts that support a 120mm PWM fan which scales from 500-1500RPM. The roughly 600 gram Nero heatsink is compatible with socket 775 and socket 1366 Intel Core 2 Duo/Quad/Core I7 processors.
