Test Setup & Methodology
We have recently made changes to our cooling department and the associated testing methodology, so please note that the number of results shown will increase over time as we add additional products. We hope that these results will appear clearer to the majority of our readership and look forward to building upon the baselines that we currently have.

Processor - Intel Core i7-3930K
CPU CoolerCorsair H100i Pro RGB
Motherboard - Gigabyte X79-UP4
Memory - 16GB Corsair Vengeance LP 1600MHz CL9
Video Card - Sapphire Radeon HD 6850 1GB
Power Supply - NZXT Hale90 650W
Storage Drive - Kingston HyperX 240GB SATA III SSD
Case - Corsair Carbide 760T

We test our fans at both 1000 RPM and maximum RPM, or if the fan only has one setting, it’s only included in the maximum RPM graphs.

Firstly, we’ll test acoustics, both as a case fan, mounted on the rear of our Corsair Graphite 760T chassis, and as a radiator fan on the Corsair H100i Pro RGB. (with the pump turned down to 1,100 RPM and all other case fans disabled). We measure the average dB(A) noise levels over 60 seconds in a quiet room with an ambient noise level of around 24dB(A). Acoustics are measured from the same point within the case (20cm from the fan), with every effort taken to ensure test parameters are as close as possible during every test.

We then test the fan’s performance both at 1000 RPM and maximum RPM by running an AIDA64 20-minute stress test while running only a single 120mm fan on the 240mm radiator of the Corsair H100i Pro RGB. This allows us to test single fans as well as multi packs by only relying on a single 120mm fan. We mount the fan under the radiator, inside the case, blowing through the radiator. We measure the average core temperature over a 60-second period and minus the ambient room temperature from this. That leaves us with a Delta °C measurement which is applied to the graphs. Our average room temperature is kept as close to 21°C as possible, roughly the room temperature of most homes and offices. Obviously, if you live in a warmer climate with warmer room temperatures, you can expect higher temperatures.

To ensure the fans RPM are measured consistently, we use the Noctua NA-FC1 fan control unit, allowing the speed of our fans to be infinitely adjusted and monitored via a nearby header on the motherboard.
