Testing
We tested the performance of the liquid cooling solution by comparing it to an air cooling product; namely the OCZ Vendetta Two. Temperature measurements were taken at idle and at full load with fans low and fans full.
Idle temperatures were taken after 1 hour of prime 95 then allowed to cool down naturally for half an hour.
Realtemp 3.0 was used and only maximum temperature readings where taken.
We also did some major overclocking in order to further stress the system.
All ambient air temperatures were at 23.5 degrees
Equipment Used:
- Core 2 duo 6320 CPU
- DFI LANPART X48 DK motherboard
- 2x GEIL DDR2 800 ram; Two gigabyte in total
- OCZ Vendetta TWO for comparison purposes.
IDLE Results for fans low and fans full at 1.8 ghz

Full load Results for 1.8 ghz

Now we go into overclocking. For air cooling we now dare not slow down the fan for the vendetta two, so whilst the 850 GT LCS will have fans low and full the air cooling solution will always be at full speed.
Overclocked to 3.0 GHZ Fans Low and Full Load

Overclocked to 3.0 GHZ and CPU Full Load

Overclocked to 3.2GHZ Idle

Overclocked to 3.2GHZ CPU Full Load

As one can see at idle the temperature difference between air and water is only about three to four degrees differential. However on full load that gap winders to between eight and ten degrees.
The CPU on air is now sot hot we dare not overclock this via air further so let us see proof via a prime 95 screen shot of the Thermaltake LCS 850 GT managing to cope with an overclock from 1.8 to 3.3ghz

We will say this about the 850 GT, it may not be designed in the best way (as our review shows) but the performance is still a great deal better than air and so justifies the whole procedure of water cooling.
Next we Have the Conclusion and Award
