Taipei, Taiwan - September, 2011 - Cooler Master, a leading manufacturer of thermal solutions, computer enclosures, CPU coolers, peripherals, and accessories, announces an impressive new ultra low profile CPU cooler. The GeminII M4 is the ultimate answer to space-constrained setups such as mini-ITX, HTPC, and any small-sized desktop PC.

Engineered to quickly dissipate heat from a CPU, the GeminII M4 is built with direct contact heat pipes that minimize CPU contact gaps and provide excellent heat conduction. It accomplishes this while maintaining a compact form that is suitable for applications with limited space. A unique heat pipe layout and a newly developed thin fan profile accentuate this ability and deliver uncompromised cooling performance. At 59mm (2.3in) height, the GeminII M4 is ready to offer the best performance when installed in many of the smallest systems.
