Testing

In order to test the ability of Thermaltake's ProWater 880i to cool a processor, I will monitor the processor's temperature over time at idle and under load. Temperatures will be gathered into four different conditions. The first test is going to be performed at idle at stock settings, which will have minimal CPU usage. During the next test, the processor will still be at stock settings, but at full load this time. I will then undergo the same testing, but with the processor overclocked. To monitor the i7's temperature, I will be using the latest version of RealTemp. In order to make sure I am really stressing the processor as much as possible, I will be using Prime95 25.7, which has the ability to achieve 100% load on eight threads. I will be using the Large FFT's test for an hour to ensure I am hitting maximum temperature. The settings used during the overclocked tests are going to make the i7 processor run 25% higher than stock speeds, which ends up at 3.33 GHz using a 166 MHz BCLK and the 20x multiplier. The processor's core voltage will be set to 1.25V. With these settings, the i7 will be dissipating an impressive amount of power. Let's see how Thermaltake's ProWater 880i will handle the load of Intel's latest quad core processors.

 

Testing Setup:

 

Settings:

  • Stock: 2.66 GHz (20x 133 MHz) 1.10V
  • Overclocked: 3.33 GHz (20x 166 MHz) 1.25V

 

Comparison Heatsinks:

  • Heatsink: AMA Aragon 900
  • Heatsink: Custom water cooling (Swiftech MCR320, Laing D5, Swiftech Apogee GTZ)
  • Heatsink: Noctua NH-U12P SE
  • Heatsink: Thermalright Ultra 120 eXtreme (push/pull Scythe Kaze 2000RPM fans)

 

 

 

 

At idle and stock settings, Thermaltake's kit fights for the number one spot against the recently reviewed kit from AMA. Cranking the fan speed to the maximum enables it to shave off that degree and take the lead. Under load, the ProWater has a solid advantage even over the custom water cooling. With the clock speed increased to a moderate 3.33GHz, Thermaltake once again wins at idle by a fair margin. It's only when under load that fan speed makes a noticeable difference, where moving from minimum to maximum takes 5 degrees Celsius off. At those settings, it can't quite keep up with the custom water cooling loop, where it loses by a one to six Celsius, depending on fan speed. Now that everything is known about the kit, let's wrap it up.
