Cooling Efficiency Tests
CPU Tests
To increase the heat dissipation our 45 nm quad-core processor was overclocked to 3.75 GHz (+25.0%). The nominal processor Vcore was increased to ~1.5 V in the mainboard BIOS (+20.0%):
The cooler we used this time together with the best thermal compounds can cool the CPU overclocked to 3.85GHz (the workload created by Linpack). However, I lowered the CPU frequency on purpose, to ensure that the least efficient thermal compounds will be able to pass. And turned out, I was right to do it this way.
Here is the table with the detailed results and the diagram with the average temperature readings (thermal interfaces have been sorted according to their efficiency and temperature increase):
The results of our test session on a CPU show that there is a group of 8 highly efficient solutions starting from the leaders IC Diamond 7 Carat and Coollaboratory Liquid Pro and finishing with Noctua NT-H1. Arctic Cooling MX-2 and Gelid GC1 fell just a little bit behind them, and liquid Zalman ZM-STG1 loses another 0.5°C to them. However, the temperature difference between IC Diamond 7 Carat and even Zalman ZM-STG1 is 2.5°C at the most, so we can recommend any of these 11 thermal interfaces for use with CPU coolers.
And further on the efficiency differences are much more dramatic and reach up to 10°C. SilMORE thermal compound bundled with many cooling solutions is the worst of the 16 products tested today, so we would strongly advise you to replace it immediately. Silver-colored AiT Cool Silver and Romanian Pro-Thermal 81 also cannot boast much, and Arctic Alumina becomes the best among the worst. I would like to particularly dwell on Coollaboratory Liquid MetalPad: its unimpressive performance in our tests must be connected with not ideally even contact surfaces, so the micro-grooves didnt get filled with the compound even despite relatively long testing period and high operational temperatures. However, the photos above as well as the results of our GPU tests prove this assumption very clearly.
GPU Tests
As I have already mentioned above, thermal interfaces were tested on the graphics card processor overclocked to 830 MHz:
The frequency lowered to 300 MHz and the voltage to 1.1V in 2D mode. The table with detailed results and the diagram with average values follow:
It is interesting that the tests on a graphics processor changed a few things within the groups, but overall the picture remained the same. However, I have to draw your attention to a serious breakthrough demonstrated by Coollaboratory Liquid MetalPad that yielded only to liquid metal. It is certainly the result of impeccably even contact surfaces. The leaders are followed by a group of 9 highly efficient thermal compounds starting with OCZ Freezer Extreme and finishing with OCZ Ultra 5+ (by the way, the new thermal interface from OCZ is really better than the predecessor in this test session). And the last ones are still the solutions with liquid consistency including Arctic Cooling, SilMORE and Zalman ZM-STG1.
