Testbed Configuration and Testing Methodology

We tested Swiftech liquid-cooling systems inside a system case with removed side panel with the following configuration:

For the primary tests and summary diagrams we overclocked our six-core processor with the clock generator frequency set at 125 MHz, the multiplier set at 35x and “Load-Line Calibration” enabled to 4.375 GHz. The nominal processor Vcore was increased to 1.385 V in the mainboard BIOS. After that we tested the new cooler at even higher frequency and voltage settings. Turbo Boost was disabled during this test session, and Hyper-Threading technology was enabled to increase the heat dissipation. The memory voltage was at 1.65 V and its frequency was 2.0 GHz with 9-10-10-24_1T timings. All other parameters available in the mainboard BIOS and related to CPU or memory overclocking remained unchanged.

All tests were performed under Windows 7 Ultimate x64 SP1 operating system. We used the following software during our test session:

  • LinX AVX Edition version 0.6.4 – to load the processor (memory - 4500 MB, Problem Size – 24234, two 11-minute cycles);
  • Real Temp GT 3.66 – to monitor the processor core temperatures;
  • Intel Extreme Tuning Utility version 3.0 – for monitoring and visual control of all system parameters during overclocking.

So, the complete screenshot during the test session looks as follows:

The CPU was loaded with two consecutive LinX test runs with the settings as indicated above. The stabilization period for the CPU temperature between the two test cycles was about 8-10 minutes. We took the maximum temperature of the hottest CPU core for the results charts. Moreover, we will also provide a table with the temperature readings for all cores including their average values. The ambient temperature was checked next to the system case with an electronic thermometer with 0.1 °C precision that allows hourly monitoring of the temperature changes over the past 6 hours. The room temperature during our test session varied between 24.0-24.5°C.

The noise level of each cooler was measured between 1:00 and 3:00 AM in a closed room about 20 m2 big using CENTER-321 electronic noise meter. The noise level for each cooler was tested outside the system case when the only noise sources in the lab were the cooler and its fan. The noise meter was installed on a tripod and was always at a 150 mm distance from the cooler fan rotor. The tested cooling systems were placed at the edge of the desk on a sheet of polyurethane foam. The lowest noise reading our noise meter device can register is 29.8 dBA and the subjectively comfortable noise level in these testing conditions was around 36 dBA (do not mix it up with low noise level). The fan(s) rotation speed was adjusted in the entire supported range using our in-house controller by changing the voltage with 0.5 V increment:

We used the same controller to adjust the rotation speed of the cooling fans with 200 RPM increment starting at 800 RPM and up to the maximum. For the same exact reasons we also included the results of Phanteks PH-TC14PE cooler in its default configuration with two fans:

It was tested in the same conditions as Swiftech systems with the removed system case side panel at 800, 1000 and 1230 RPM fan speed.
