Zalman LQ315 Liquid Cooling System Review
Zalman LQ315 Liquid Cooling System Review
  70%   
Abstract: 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. Like most water coolers on the market right now this system is designed and built for OEM use by Asetek.

FrostyTech Mk.III Synthetic Thermal Heatsink Test Results
Intel Core i7, Extreme Edition class heatsinks tested at a 200W heat load.
Results based on readings from a 38x38mm copper interface die with 200W heat load on the Intel version of the Mk.III Test Platform. Temperature results listed for each heatsink were calculated by determining the rise over ambient temperatures at time of test. Information on Frostytech's test methodology is available here.

*heatsinks are ranked according to the 125w thermal test results column (rise over ambient temp.). low temperatures with low noise levels are considered best. for reference heatsinks with variable-speed fans, only the high speed (12v) fan test result is included in the comparison sheet; more detailed results reside in each specific heatsink review.

Frostytech's socket LGA2011 Intel synthetic thermal test platform stresses socket LGA2011/1366 compatible heatsinks with a 200W heat load. Keep in mind that the AMD Integrated Heat Spreader and Intel LGA2011 Integrated Heat Spreader both measure ~38x38mm, so these test results can be extrapolated to AMD processor scenario's as well.

With a 200W heat load applied by the Intel LGA2011/1366 version of FrostyTech's synthetic thermal test platform, the Zalman LQ315 yielded a temperature result of 21.9°C over ambient at stock fan speed. Reducing the speed of the LQ315's single 120mm PWM fan from 2000RPM to 900RPM saw lowered noise output greatly and caused test temperatures to rise to 34.0°C over ambient.

Ultimately, of the three Zalman water coolers Frostytech tested, the LQ315 performed the poorest. While it did have a slightly thicker heat exchanger than the LQ310 system, the waterblock on the LQ315 we tested was simply too convex and made poor contact with the flat copper CPU die on our synthetic thermal test platform. This could be a manufacturing one-off, but given all three LQ-units were convex to one degree or another it seems the waterblock design isn't quite as refined as it could have been. In this instance, we'd recommend passing over the LQ315 for Zalman's LQ320 model - the cost difference between the two is marginal and the later demonstrated better thermal performance.
