Our Tests

The table below presents the results of our measurements. We repeated the same test on each cooler listed below, with the CPU at full load.

As we are comparing the temperature difference between the CPU and the air outside the computer (and not the actual CPU temperatures), there is no bias in taking measures under different room temperatures. Both heat transfer physics and our practical tests proved this.

Cooler Room Temp. Noise Speed Core Temp. Temp. Diff.
Thermaltake Water 3.0 Ultimate 21 °C 46 dBA 1200 rpm 55 °C 34 °C
Corsair H100i GTX 22 °C 52 dBA 2050 rpm 58 °C 39 °C
Thermaltake Frio Extreme 19 °C 49 dBA 1450 rpm 56 °C 35 °C
SilverStone AR01 21 °C 46 dBA 1900 rpm 65 °C 44 °C
Corsair H45 21 °C 53 dBA 2000 rpm 59 °C 38 °C

In the graph below, you can see how many degrees Celsius hotter the CPU core is than the air outside the case. The lower this difference, the better is the performance of the cooler.

In the graph below, you can see how many decibels of noise each cooler makes.
