Korean enthusiast PC components major Zalman announced a trio of closed-loop liquid CPU coolers, the LQ310, LQ315, and LQ320; which are designed to handle maximum thermal loads (Qmax) of 300W, 330W, and 340W, respectively. The USP for all three is an extremely dense copper micro-fin structures inside the main block, where heat is dissipated to the coolant. The three feature what is essentially the same block and pump, and differ with the size of the radiator.

The Radiator component of the LQ310 measures 153 x 120 x 25 mm, that of the LQ315 is slightly thicker, at 35 mm, and LQ320 at 51 mm. A Zalman-made 120 mm fan, with 900 to 2,000 RPM speed range, long life bearing, and 4-pin PWM control, is standard issue for all three models. All modern CPU socket types are supported by the three, including LGA2011, LGA115x, AM3+/AM3, and FM2/FM1. The LQ310, LQ315, and LQ320, are priced at US $85, $100, and $120, respectively.
