Heat sinks may not ordinarily be the most exciting sort of component -- but the world's thinnest air-cooled heat sink? That's... something. According to the folks at Novel Concepts, their new credit card-sized, 0.75mm thick ThinSink has now laid claim to that title, and it may soon lead to thinner tablets, laptops and monitors. What's more, despite its small size, the company claims that the ThinSink still has a cooling efficiency "25 times greater than today's best microprocessor heat sinks," and it consumes just 0.031 watts of electricity when equipped with a fan spinning at 6,000 RPM. Those interested in an evaluation unit will have to fork over a hefty $750, but the company promises it will be cheaper in larger quantities, and notes that it could also easily be stamped or molded from metal or plastic, as it only consists of two thin flat parts in addition to the motor.

Novel Concepts Announces ThinSink™, the World's Thinnest Air-Cooled Heat Sink
LAS VEGAS, May 9, 2011 /PRNewswire/ -- Novel Concepts, Inc. announced today that it has developed and has patents pending for the world's thinnest forced convection (fan cooled) heat sink, dubbed ThinSink™. Thinner than a credit card, this low-profile ThinSink has a volumetric cooling efficiency 25 times greater than today's best microprocessor heat sinks, which means it cools 25 times more heat per cubic centimeter.
Developed to fit inside small electronic devices such as notebooks, monitors, and tablets, ThinSink efficiently cools integrated circuits, semiconductors, LED's and other microelectronic heat generating devices.
ThinSink's smooth fan surface requires very little electrical power. A credit card-sized ThinSink (85mm by 55mm by 0.75mm), using a 40mm diameter smooth fan, spinning at 6,000 RPM, consumes only 0.031 watts of electricity (up to 2 days on a AAA battery) (click for chart).
Even with its low power consumption, this same credit card-sized ThinSink has an amazing thermal performance of 2.73 degrees Centigrade per watt at a fan speed of 6,000 RPM.
ThinSink is also extremely quiet, due to its thin, smooth fan surface, which eliminates the pulsating sound and vibration caused by traditional fan blades. At 6,000 RPM, this credit card-sized ThinSink has a sound output less than 34 dBA (quieter than a soft whisper at one meter distance).
Since ThinSink is thin and flat, it's also very lightweight. An aluminum credit card-sized ThinSink weighs only 13.8 grams, including motor, and only occupies 4.5 cubic centimeters of space.
Additionally, ThinSink may be very cost effective. Excluding the motor, ThinSink has only two thin flat parts, which can be stamped or molded from metal or plastic.
