This bunch of neatly arranged copper rods caught our eyes at Computex. Called the "Blonde Hedgehog," the exhibit below is a new heatsink design concept, in which numerous copper rods bunch up inside a ring, which makes up the base, where they make direct contact with the CPU, and fan-out towards the top. A fan then ventilates the bunch. The copper rod design ensures extremely high surface area for dissipation, the down-flow of the air cools other components surrounding the CPU socket, as well. The rods are held together by pressure, and not welding. In fact, the designers are bragging about the design being weld-free.Warm Tek has two variations of the design, the standard one, Blonde Hedgehog C120, has exposed copper rods, and measures 140 x 140 x 90 mm, utilizing a 120 mm custom-design fan. The exposed copper rods are put through anti-oxidant treatment at the factory. There's a variant with nickel-plated copper rods, too. Another, slightly different and smaller variation of this, is called Baby Hedgehog, which measures 90 x 90 x 30 mm, and is meant for low-power CPUs.
