Testbed and Testing Methodology
We performed all cooler tests inside a closed system case with the removed side panel. Here is our testbed configuration:
- Mainboard: Gigabyte GA-X58-UD9 (Intel X58 Express, LGA 1366, BIOS F5 from 5/4/2011);
- Processor: Intel Core i7-980X Extreme Edition, 3.33 GHz, 1.225 V, 6 x 256 KB L2, 12 MB L3 (Gulftown, B1);
- Thermal interface: SilMORE;
- Graphics card: ATI Radeon HD 5770 1 GB GDDR5 128 bit, 850/4800 MHz;
- Memory: DDR3 3 x 2 GB OCZ Platinum Low-Voltage Triple Channel (Spec: 1600MHz / 7-7-7-24 / 1.65 V);
- System drive: RAID-0 of 2 x Kingston V-series SNV425S2128GB SSD (SATA-II, 128 GB, MLC, Toshiba TC58NCF618G3T controller);
- Drive for programs and games: Western Digital VelociRaptor (300GB, SATA-II, 10000 RPM, 16MB cache, NCQ) inside Scythe Quiet Drive 3.5” HDD silencer and cooler;
- Backup drive: Samsung Ecogreen F4 HD204UI (SATA-II, 2 TB, 5400 RPM, 32 MB, NCQ);
- System case: Antec Twelve Hundred (front panel: three Noiseblocker NB-Multiframe S-Series MF12-S2 fans at 1020 RPM; back panel: two Noiseblocker NB-BlackSilent PRO PL-1 fans at 1020 RPM; top panel: standard 200 mm fan at 400 RPM);
- Control and monitoring panel: Zalman ZM-MFC2;
- Power supply: Xigmatek “No Rules Power” NRP-HC1501 1500 W (with a default 140 mm fan).
Our six-core processor (with its default non-lapped heat-spreader) with the multiplier set at 25x and “Load-Line Calibration” (Level 2) enabled worked at its nominal speed and with nominal Vcore:
Turbo Boost and Hyper-Threading technologies were disabled during our test session. The memory voltage was at 1.64 V and its frequency was 1066 MHz with 7-7-7-16_1T timings (Extreme profile). 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:
- CPU Stress Test (CST) version 0.18b – to load the processor (matrix # 15, 10-12 minutes);
- Real Temp GT 3.64 – to monitor the processor core temperature;
- CPU-Tweaker 1.5 – to visually monitor temperatures and frequencies using graphics;
- Gigabyte Easy Tune 6 B11.2303.1 – to monitor voltages.
The CPU was loaded with two consecutive CST 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 23.6-24.0 °C.
We are going to compare both today’s newcomers against the inexpensive Cooler Master Hyper 212 Plus ($29.50), which also uses heatpipes direct-touch technology. It was tested with one default Blade Master 120 fan. It turned out more than enough to estimate the cooling efficiency of Auras products.
Now let’s check out the obtained results.
