Testing and Setup:
Testing of these heatsinks will involve applying a load simulated by Prime95, using small FFTs in stock and overclocked scenarios, where both idle and load temperatures will be recorded. Load temperatures will be the maximum value displayed in RealTemp after running eight threads in Prime95 for one hour, and idle temperatures will be the minimum recorded value by RealTemp with no computer usage during a period of one hour. The temperature values for each of the four cores will be averaged and displayed in the graphs below. The ambient temperature is held at a constant 23 °C throughout testing of the Transformer 3, HPL-815, as well as the comparison units. All the data shown in the graphs below is in degrees Celsius. The included thermal paste from Evercool will be used during testing and thermal pastes on other heatsinks from their respective manufacturers will be used. The fans on each cooler will be run at full speed for these tests.
Testing Setup:
- Processor: Intel Core i7 920 - Stock and @ 3.44ghz, 1.27v
- Cooling: Evercool Transformer 3 and HPL-815
- Motherboard: MSI X58 Platinum SLI
- Memory: Mushkin Blackline PC3 16000 9-9-9-24 1600MHz
- Video Card: XFX HD6970 2GB
- Power Supply: Mushkin 1000 watt Joule Modular power supply
- Hard Drive: 1 x Seagate 1TB SATA
- Optical Drive: Lite-On DVD-RW
- OS: Windows 7 Professional 64-bit
- Case: Corsair Graphite Series 600T
Comparison Heatsinks:
- Stock Intel heatsink
- Cooler Master Hyper 612 PWM
- Cooler Master GeminII S524
- NZXT Havik 140
- Corsair H60
- Noctua NH-D14
- Noctua NH-U12P SE
Well we see here that the Transformer 3 does quite a good job at keeping the processor cool while idle, and this is probably thanks to the very well-finished, direct contact heatpipe base. The load temperature actually ties the H60! The HPL-815, did a good bit better at idle than the stock Intel unit does, but once it started to get some heat on it the performance tapered off. In fact, it allowed the CPU to pass 100°C on the overclocked load test.
