Raijintek's Themis heatsink stands 158mm tall and weighs 448 grams. It's designed for Intel socket LGA2011/1366/115x/775 processors and AMD socket AM2/AM3/FM1/FM2 CPUs - should any still be in existance. The heatsink design is your bog-standard, three-8mm-heatpipe-exposed-base-tower-cooler we've all seen countless times before. The 120mm PWM fan operates at 1800-1250RPM and moves upwards of 78CFM according to the manufacturers specs. Noise output is modest to audible. Rubber fan mounts make mounting the fan relatively easy during the installation process, but for some reason Raijintek are counting their pennies and include just enough fan mounts for ONE fan, one fan only. Expect to find the Raijintek Themis heatsink selling for around $34 USD.
