Corsair Hydro Series H75 Liquid CPU Cooler Review

Testing Configuration and Benchmarks Used

View Full Size

To verify that the cooler kit operates up to specs, the Corsair Hydro Series™ H75 Liquid CPU Cooler was tested with the CPU running in both stock and at a known stable overclocking speed using both Z77-based and Z87-based motherboards, so that comparative results could be provided for both Ivy Bridge and Haswell-based systems. The results are presented for the cooling kit under review as well as the Corsair H100i water cooler, XSPC Raystorm 750 EX240 water cooling kit, and the Thermalright SilverArrow SB-E air cooler for performance comparison purposes. The benchmark tests used should give you a good understanding of the cooler's capabilities so that you, the reader, can make a more informed purchasing decision. The comparison coolers were selected based on their superior performance capabilities.

The 64-bit Windows 7 based test bench used for LGA1155 board testing includes an Intel Core i5-3570K CPU, 8GB of DDR3-2133 memory, an MSI R7870 Hawk 2GB video card, and an Intel 520 240GB SSD drive. Using the selected components gives us the ability to demonstrate the cooling system's capabilities rather than that of the system components.
