Tests, Tools and Methodology:
How We Tested:
We are testing in 3 different configurations as outlined below. Each configuration will be tested with 3 different fans. We repeat the tests 3 times for each configuration and fan setup. A fresh application of TIM and a remount is performed between tests. This results in a total of 27 test results. We then calculate the averages for each configuration and fan setup.
The test itself is 45min long and consists of a 5min warm up / idle period which is followed by a 8 thread Prime95 load test and concludes with a 10min cool down period.
Setup #1: Stock @ 2.66 GHz (2.80 GHz)
| BCLK | 133 MHz |
| CPU Ratio | x21 |
| Vcore | 1.15v – LLC Enabled |
| VTT | 1.2v |
| UNcore | x21 |
| RAM DDR3 | 1066 / 7-7-7-20 1T |
Setup #2: Medium OC @ 3.60 GHz
| BCLK | 180 MHz |
| CPU Ratio | x20 |
| Vcore | 1.3v – LLC Enabled |
| VTT | 1.2125v |
| UNcore | x18 |
| RAM DDR3 | 1440 / 8-8-8-24 1T |
Setup #3: Overclocked @ 4.00 GHz
| BCLK | 200 MHz |
| CPU Ratio | x20 |
| Vcore | 1.4v – LLC Enabled |
| VTT | 1.35v |
| UNcore | x16 |
| RAM DDR3 | 1600 / 8-8-8-24 1T |
We use 2 predefined fans for measurement consistency and to determine how well the cooler will scale for silence and performance. If the manufacturer supplies a fan, the factory fan will be included in all tests as well.
| FAN #1: | SanAce | xxxxxx1011 | 120x120x38 | 120 CFM |
| FAN #2: | Scythe Gentle Typhoon 15 | 120x120x25 | 58 CFM |
| FAN #3: | Antec | 120x120x25 | 110 CFM |
Bench Table:
All tests will be conducted on an open test bench.
- Lian-Li PC-T60b is the bench table used for all benchmarks and stress testing.
- Arctic Cooling MX-4 Ultra Premium Thermal Compound was used for all tests.
- Arctic Silver ACN-60ML + Microfiber cloth is used for TIM removal.
Test Tools:
| Thermometer #1: | CystalFontz DB635-AKTMF-KU3 |
| Thermometer #2: | 2x CystalFontz WRDOW17 Temp Sensor |
This will be used to measure and monitor ambient temperature. The ambient temperature window is between 25C – 27C degrees. The target temperature is 26C degrees.
