Cooling Efficiency Tests

You can view the results in the next diagram as well as the detailed table below.

A few explanations are necessary. None of the three coolers copes with our CPU at a fan speed of 600 RPM. Therefore the results begin at 800 RPM in the diagram. The maximum speed of the Ice Matrix 600’s fan being 1200 RPM, we tested that cooler with a fan from the ThermoLab Trinity at the higher speeds.

Neither of the two new coolers boasts high performance. They are both inferior to the Zalman CNPS10X Performa in each mode without exceptions. The ThermoLab Trinity is more effective than the Deep Cool Ice Matrix 600, though. The latter's performance doesn’t depend much on the speed of its fan: when the default fan’s speed is increased from 800 to 1200 RPM, the peak CPU temperature lowers by 7°C only (from 92 to 85°C). When equipped with the Trinity’s fan, the Ice Matrix 600 lowers the CPU temperature by only 3°C as its speed grows from 1200 to 1800 RPM. By the way, the addition of a second Deep Cool UF140 fan for exhaust helps the cooler at 600 and 800 RPM only. At 1000 and 1200 RPM the second fan lowers the temperature by a mere 1-2°. Well, that’s what we might have expected from a heatsink that is only 45 millimeters wide.

The ThermoLab Trinity behaves in a different way. When its default fan accelerates from 800 to 1200 RPM, the top temperature of the hottest core of our six-core CPU lowers by 8°C (from 93 to 85°C), yet the cooler's performance can be increased even further. The temperature lowers by 4°C more at 1400 RPM, by 3°C more at 1600 RPM, and by 1°C more at 1800 RPM. As a result, the Trinity beats the Ice Matrix 600 at high fan speed although is inferior to it in quiet mode. You can also note one more thing about the Trinity: the CPU is 10°C hotter with this cooler than with its opponents in idle mode. This must be due to the original implementation of the direct-touch technology.

The Thermalright Archon, being our reference point in this comparison, surely hails from a higher league both in performance and noise level. Working at 800 RPM, the Archon beats the Ice Matrix and the Trinity by as many as 12-13°?!

Acoustic Performance

We measured the amount of noise produced by the coolers throughout the speed range of their fans according to the method explained above. You can see the result in the next diagram:

The Deep Cool Ice Matrix 900 proves to be the noisier of the two new products. Up to the subjectively noiseless level of 33 dBA the Deep Cool UF 140 fan is successfully competing with the Trinity's fan but they part their ways at the subjectively comfortable level of 35 dBA. While the Ice Matrix 600 is comfortable up to 940 RPM, the Trinity remains such at speeds up to 1010 RPM. The Trinity is also superior to the Ice Matrix 600 in terms of noisiness at the higher speeds, too.

We should note that we didn't hear any unwanted sounds from either fan. There was no rattle, vibration, clanging or anything. So, both coolers come with high-quality fans, and the Deep Cool UF140 is even attractive visually.

Our reference cooler Thermalright Archon beats the two newcomers in this test, too.


We must confess we expected somewhat better results from the Deep Cool Ice Matrix 600 and the ThermoLab Trinity. Yes, each cooler copes with our six-core CPU working at 4.32 GHz and 1.4 volts Vcore, but this is no great achievement in our cooler tests. There are well over a dozen air coolers capable of that today, including cheaper ones like the Zalman CNPS10X Performa we’ve included into this test session for the comparison’s sake. The support for multiple platforms and the simple installation procedure of the Ice Matrix 600 and the Trinity do not constitute a special advantage today. The new coolers are not very quiet, either (but we must note that the Trinity is somewhat quieter than the Ice Matrix 600 at the same fan speed). And while the Deep Cool is more or less competitive in terms of pricing ($40), the ThermoLab with its recommended $52-58 seems to be a little overpriced. So, at this point we’d recommend you to consider other coolers which are available aplenty on the market. However, some users may want to buy one of these two products just to have a piece of the Matrix in their computers. :)
