Zalman released three water coolers in the hand of PC enthusiasts earlier this year, in this review Frostytech is testing out the LQ315 model - the middle child as it were. The LQ315 ships fully assembled, plumbed and filled with a coolant. It installs onto Intel socket LGA115x/1366/2011 and AMD socket AM2/AM3/FM1/FM2 processors. It uses a 120mm wide aluminum heat exchanger equipped with a single 120mm PWM fan that operates at 2000-900RPM. The pump/waterblock is built around a novel micro-skived copper base plate that is connected to the heat exchanger via a 30cm length of flexible rubber tubing.
