Remember the Sandia CPU cooler concept from 2011 which never really saw the light of the day? Thermaltake drew a few design cues, and launched the Engine 27, a low-profile CPU cooler with the heatsink-impeller design. As with Sandia, the Engine 27's design involves a metal heatsink base that makes contact with the CPU, which conveys heat to a motorized fan-shaped moving heatsink suspended along an axle and conductive lubricant. The rotation of this moving heatsink dissipates heat. To give Thermaltake credit where due, the company took the concept a notch above and gave the base-plate a static aluminium channel heatsink of its own, so the exhaust from the heatsink-impeller takes in some additional heat on its way out.

The Thermaltake Engine 27 derives its name from its 27 mm height (meets 1U spec), and probably the fact that it looks like the core of a jet engine. The company is still claiming pretty benign noise output figures of 13-25 dBA, depending on its speed range of 1500-2500 RPM (pretty neat for a 60 mm fan). Measuring 27 mm x 91.5 mm x 91.5 mm (HxWxD), the cooler weighs about 310 g, and supports LGA115x sockets (LGA1156/LGA1155/LGA1151/LGA1150). The fan supports 4-pin PWM power input. The company didn't reveal pricing.
