Performance Tests

Cooling Efficiency


The results of our performance tests of the coolers in their default configurations can be viewed in a table and in the next diagram:

The Frio Extreme seems to be as efficient as the excellent Thermalright TRUE Spirit 140. However, when we recall that the former is twice as expensive as the latter and note that the Frio Extreme can only do that by using two high-speed fans, its results are rather disappointing. Of course, the Thermalright Silver Arrow SB-E and the Phanteks PH-TC14P?, which are as expensive as the Frio Extreme, would beat the latter black and blue in this competition. Well, what else could we expect from the convex base and the press-fitted fins?

You can compare these coolers with those we tested previously in the following table and diagram. Each cooler was tested in its default configuration in the quiet mode and at the maximum speed of the fan(s) with the CPU overclocked to 4.375 MHz at a voltage of 1.385 volts.

* - The peak temperature of the hottest CPU core is posted on the diagram taking
into account the difference from the current ambient temperature and is reduced to 25°C.

At the maximum speed of its two 140mm fans the Frio Extreme can deliver high performance and compete with the Zalman CNPS12X or the Thermalright Archon but its noise level results indicate the price you have to pay for that performance. At the minimum speed of 800 RPM the new cooler is as efficient as the liquid cooling system Intel RST2011LC WC at the maximum speed of the latter’s fan or as the air cooler Noctua NH-D14 SE2011 at 800 RPM.

As for maximum CPU overclocking, the Frio Extreme could make our CPU stable at 4500 MHz and 1.415 volts while working at the maximum speed of its fans. The CPU had a peak temperature of 78°C.

Thermaltake Frio Extreme
(2 fans x 1810 RPM)

Thermalright TRUE Spirit 140
(1260 RPM)

We could achieve the same CPU clock rate with a Thermalright TRUE Spirit 140 with one fan at 1260 RPM, and the peak CPU temperature was even 2°C lower than with the Thermaltake Frio Extreme. We can note that when the ambient temperature was somewhat higher than 25°C, the TRUE Spirit 140 couldn’t keep the CPU stable at the mentioned frequency and voltage, but it can do that at 21.5°C. So, we can suppose that the overclocking results of the Thermaltake Frio Extreme and Thermalright TRUE Spirit 140 are going to be lower during the hot summer period.

Here are the table and diagram with the maximum CPU overclocking results:


The Thermaltake Frio Extreme is in the middle group, between the Deepcool Assassin and the Thermalright Archon. We have to note that it’s got the highest level of noise among all the coolers we’ve tested, though.
