Testing and Methodology

As always at overclockerstech the waterblock was subjected to a harsh and thorough testing procedure, which involved subjecting both of the blocks under test to the use of Thermochill UV green fluid. Each product under test was subject to at least one hours full load before cooling down for thirty minutes, only then were the idle temperatures taken. Full load temperatures were only taken only after idle temperatures were complete.

An inline sensor was placed in the ‘fluid in’ and another in the ‘water out’ sections. Additionally sensors were installed before and after radiator in order to monitor air in and out of the radiator. CPU temperatures were taken by the use of realtemp 3.0 whilst the processor was brought to full operational capacity by using Pime95,ambient air was kept at a consistent 24.1 degrees. Lastly the pump for the water cooling system was installed onto another power supply in order for the temperature readings to be stable. All thermal compound was placed using a 5.5milimetre blob in the centre of the processor and cleaned using Isopropyl alcohol after every use. As previously stated all results are compared to that of the Watercool Heatkiller 3.0 (copper version).

Testing Equipment

DFI X58 UT T3EH8 (ChipSet water cooled)
Core I7 920D0 Processor
1/2″ ID tubing
Thermochill PA 140.3 radiator with three mid-range 140mm Sharkoon fans.
Innovation Cooling IC7 Diamond compound (was given fifty hours of curing for each block)

Idle Tests

The first test shows the temperature of the air flowing into and out of the radiator.

One cannot explain the sudden jump on core two in regards to the Heatkiller tests, the only thing that could spring to mind is that is might have bene possible for some unknown background task.
