Enermax today unveiled its latest CPU cooler dubbed the ETS-T40. The new CPU cooler is designed for quiet and effective cooling, featuring a patented SEF (Stack Effect) based on Bernoulli's Law, to enhance heat transfer. Enermax claims that the ETS-T40 has a "world leading" thermal resistance value of 0.09°C/W. A Vacuum Effect (VEF) forces air to flow through the fins of the heatsink, helping increase cooling capability. In addition, the heatsink also uses Vortex Generator Flow (VGF) technology to improve air convection around the fins. The ETS-T40 CPU cooler has 52 aluminum fins, backed by four 6mm Heat Pipe Direct Touch (HDT) copper heat pipes, for rapid heat dissipation. Extra cooling power is provided by an 120mm Twister-bearing fan running between 800 and 1800RPM. The ETS-T40 heatsink has a rated maximum noise output of 26dBA and weighs in at 610g. The Enermax ETS-T40 heatsink will be available in three variants, each with a different fan type: either dual color LEDs, a single color LED, or no LED. The new heatsinks are compatible with a wide range of Intel and AMD sockets, and will be priced from US$39.99.
