Corsair H100i Cooling Performance

Testing and Results

We measure the CPU temperature of our test rigs when the CPU is idle (Windows desktop) and under load (by running the smallfft test in Prime95). We use the freeware application CoreTemp to measure the temperature of the Intel CPUs, which reads the data from the DTS (digital thermal sensor) embedded in the core of every modern CPU. The DTS gives a far more accurate reading than any third-party temperature sensor, because its readings are not affected by sloppy BIOS programming or a poorly calibrated external health monitoring chip on the motherboard.

Because we don't have a temperature control chamber, it's more accurate to measure and quote the delta T (difference) between the ambient and CPU temperature. This means HSFs (heatsinks and fans) that were tested on different days, when the ambient temperature may have varied, can be fairly compared to one another. You'll find the temperature results for the reference HSFs in the graphs. We normally compare the results of each cooler to the reference cooler.

However for the Socket AM3+ and LGA2011 systems, we didn't have the reference coolers for these at time of testing, so the cooling scores are compared against other coolers rather than how much better the cooler was than the reference cooler.

LGA1155 test system:
  • Core i7-2600K overclocked to 4.1GHz using a vcore of 1.325V
LGA2011 test system:
  • Core i7-3960X Extreme Edition overclocked to 4.3GHz using a vcore of 1.285V
Each test rig is built inside a SilverStone PS03 midi-tower case and includes an Nvidia GeForce 9600 GT graphics card. The temperatures shown are the delta T between ambient and CPU temperature.

Please note that, unfortunately, our AMD test system has keeled over and died. While we are currently working on a replacement, we have only had the opportunity to test the H100i in our two Intel systems.
