Testing & Results

For testing I will measure the temperatures of the CPU at idle 10 minutes after booting into Windows, then run Prime95 instances on all cores to torture test the CPU at 100% for 30 minutes and again measure the temperatures. Lastly, I will overclock my CPU to run at 4.0 MHz and repeat the steps for idle and full load. This will all be done TWICE, and the temperatures will be averaged to provide the final results.  This will eliminate any minor discrepancies, should any arise.  All temperatures will be measured using the latest version of Realtemp which will accurately record the temperatures for all four cores of the CPU.

Test Setup

Below are the results:


As you see above, the Domino performs very well at Idle, providing temperatures a couple degrees Celsius above room temperature and is performing close to a really expensive air cooler and better than most air-cooled processors. So at this point Domino is doing its job very well and displaying all the relevant information on the LCD screen which is really nice to observe in real-time as the test are running.

A torture test that produces these temperatures is an excellent result, and particularly when you factor in that the Domino retails for only $79. We see differences of 1 degree Celsius for each performance mode, showing that indeed there is a discernible difference, though it’s not much.  We’re starting to see a trend here, but we’ll reserve our conclusions until the end.

Let’s crank up the juice now and overclock the Quad Core CPU and see what happens below.


With the CPU running at 4.0 GHz and an increased voltage, we see an Idle temperature increase of approximately 5C across the board.  The Idle temperatures are still excellent on a highly overclocked Quad Core CPU. In the torture test, the Domino is there with a glass of water and a dry towel making sure this thing isn’t getting too hot. Once again, we see at 40% overclock were still in the 40’s (Celsius) for the most part, with the Quiet setting just barely flirting with 50 degrees Celcius. This is great and it compares favorably to top high-end air cooling and even some other pre-built water cooling kits we’ve seen, but at a much better retail price.

There are a few things we’ve seen here to draw conclusions.  The first is that the Domino produces excellent results across the performance spectrum, at Idle and Load, for both a stockclocked and overclocked Quad Core CPU.  The second conclusion is that the Domino pulls down some very impressive numbers even at the Quiet setting.  And lastly, but perhaps most significantly, is that the performance difference between the Quiet and High Performance settings is not that vast.  What this means is that it’s not absolutely necessary to run the Domino at the highest fan speed to see a huge difference in performance.

In fact, we believe that most people can actually run the Domino at the Quiet or Performance setting, allowing you to achieve a very good temperature, and keep your setup very quiet.  At High Performance, the Domino is definitely not quiet, and from what we’ve seen above, that’s not necessarily an issue because you can run the unit at slower fan speeds and still achieve great results.  Accordingly, we recommend that most people choose the medium or lowest fan setting for the Domino, which will result in an excellent balance of performance and lower noise levels.
