The table below presents the results of our measurements. We repeated the same test on each cooler listed below. Each measurement was taken with the CPU at full load. On the Water 2.0 Extreme, the fan speed was set on the control software that comes with the cooler, and on the Water 3.0 Ultimate, the fan speed was adjusted in the motherboard setup.
|Cooler||Room Temp.||Noise||Speed||Core Temp.||Temp. Diff.|
|Thermaltake Water 2.0 Extreme (maximum)||17 °C||55 dBA||1,950 rpm||58 °C||41 °C|
|Thermaltake Water 2.0 Extreme (minimum)||17 °C||44 dBA||1,250 rpm||60 °C||43 °C|
|Thermaltake Water 3.0 Ultimate (maximum)||17 °C||56 dBA||1,900 rpm||41 °C||24 °C|
|Thermaltake Water 3.0 Ultimate (minimum)||17 °C||43 dBA||1,050 rpm||48 °C||31 °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.
