To test the performance of the Antec Kuhler H2O 1250 we built a powerful X79 based system on an open test bench to push the cooler to it’s limits. As we were testing on an open test bench, we directed a Be Quiet! Shadow Wings 120 mm fan at the VRM circuitry to better simulate the airflow generated in a case.
Test System
- Processor: Intel Core i7-3930K
- Motherboard: Asus P9X79
- Memory: 16 GB (4 x 4 GB) Mushkin Blackline 1600 MHz
- Thermal Paste: Arctic Cooling MX-2
- Graphics Card: AMD Radeon HD 7950
- Graphics Card (noise tests): HIS Radeon HD 5550 Silence
- Power Supply: Seasonic Platinum P1000W
Software
- Prime 95 (64-bit)
- CPUID Hardware Monitor
Overclocking
We manually overclocked the i7-3930K to 4.7 GHz by increasing the multiplier to 47x, leaving the baseclock set at 100 MHz. We set Load Line Calibration to ‘High’, and increased the CPU Current Capability to 120% with a minor voltage increase. Speed stepping was disabled for both stock and overclocked tests.
Its a nice idea, but I dont like the concept myself. its too bulky for a start and I like using my own fans in these configurations.
I would like to know if I can use the new software “Antec Grid” with my Antec 920 water cooler. It’s nice to choose a fix fan speed and I don’t like the ChillControl because, in my opinion is very complicated to use the custom option.
