I tested the system using three various cooling solutions, two air units and of course the Iceberg liquid unit. I also got the results for this test in two very different ways.

The first method of testing was based on the results shown by the hardware monitor available in the POSr screen and BIOS of the EPOX 8K3A+. The other results were scores gotten from placing a CPU doctors temperature gauge wire between the CPU top and the cooling solution.

The major difference in the tests shows the liquid cooling solution being about eight degrees cooler than the on-board hardware monitor shows while the air cooled device only showed about two degrees difference which was quite eye opening.

The on-board CPU hardware monitor reads the area around the chip to get its results and not the area above the CPU die itself. With the air blowing down the air solution showed almost the same results in both tests but the liquid device circulates no air hence does not truly show the dies temperature.

Placing the CPU doctors thermostat reader between the CPU and cooler enabled me to see the liquid solution in a different light. The liquid cooling solution is actually cooling the CPU better than the hardware monitor shows and by quite a margin as well.

Another thing to seriously consider is the noise factor and how much you can handle. I used the Swiftech MCX370 because it is one of the best if not thee best air cooled solution for the AMD CPU line and the Thermaltake Volcano 6 as it is one of the most popular solutions sold on the market.

The drawback to both of these solutions is the fan noise created by them, as they need high RPM fans to keep those nasty CPU temperatures at bay. The Iceberg solution however is virtually silent due to the fact that the only fan running is the rear case fan that would still be running in any event.
