Official description: “The Zalman CNPS FX100-Cube is fanless and noiseless CPU cooler, which does not draw dust or generate vibration due to its passive operation.” Unofficial description: LOOK AT THIS FREAKING MONSTER HEATSINK!
Made of copper and aluminium, this 880g cooling thingamajig works with 77W TDP (Thermal Design Power) processors, “including Intel’s i7-3770K”. I admire those who still build their own PCs. Respect. [Fanlesstech]
