Cooling Efficiency Tests

First of all I have to say that there is no difference in cooling efficiency between Phanteks coolers of different colors (red and silver). Speaking of the individual processor cores the temperature was 1°C lower under the silver model. However, these deviations are most likely connected with the more/less successful installation of the cooler on the processor heat-spreader.

The results of our cooling efficiency tests are summed up in the diagram and table below:

When we compared the two coolers tested with their default fans (two fans by Phanteks PH-TC14PE and one fan by Thermalright Archon), the Phanteks newcomer won a convincing victory. At 600 RPM PH-TC14PE was 7°C more efficient, at 800 and 1000 RPM - 5°C more efficient, and at speeds beyond 1200 RPM – Archon is only 2°C behind. At the same time, the performance of the new Phanteks PH-TC14PE with only one default fan installed between the two heatsink arrays show that this cooler can compete against Archon with one cooling fan. Only at maximum fan speed, which is higher by TY-140 (1260 RPM compared with 1210 RPM of the Phanteks fan), Thermalright cooler is 3°C more efficient. However, in my opinion, no one will really purchase expensive Phanteks PH-TC14PE with intention to remove one of its fans. There are cheaper and more compact models available in this case.

As for the performance of PH-TC14PE and Archon coolers tested with two identical Thermalright TY-140 fans, the Phanteks newcomer again doesn’t give in to its powerful competitor. On the contrary, Thermalright TY-140 fans fit the PH-TC14PE heatsink even better than the original ones, because at the same rotation speeds the “upgraded” Phanteks PH-TC14PE is up to 2°C more efficient than the original configuration. As a result, the new Phanteks cooler is 2-3°C more efficient than Thermalright Archon when both are tested in identical conditions at the same speeds of the same exact fans. This is substantial difference for a super-cooler. I would also like to add than by adding the third fan to the PH-TC14PE heatsink we can only improve its cooling efficiency at 600 RPM speed by about 2°C. We didn’t detect any changes at higher speeds compared with the two-fan configuration.

The maximum overclocking tests of our six-core processor under Phanteks PH-TC14PE proved that it is a superior product that is capable of cooling our Gulftown CPU with over 250 W calculated TDP, which was successfully overclocked to 4.5 GHz frequency at 1.46875 V Vcore:


2 Phanteks PH-F140TS (at 1210 RPM)

2 Thermalright TY-140 (at 1260 RPM)

Here I would like to point out once again that alternative Thermalright fans do a better job with Phanteks heatsink than the original PH-F140 ones, because with alternative fans the peak temperatures end up being 2-3°C lower.

Now let’s add the results for Phanteks PH-TC14PE cooler at maximum fan speed and in quiet mode into our summary diagram and table*:

.

Phanteks PH-TC14PE has obviously taken the leading positions in our performance ranks although it was as efficient as Thermalright Archon with two TY-140 fans (as you know the default Archon configuration includes only one fan like that).

The next diagram and table sum up the maximum CPU overclocking results for each tested cooler. Besides the CPU frequency, they also show maximum CPU temperature (taking into account the room temperature delta) and the generated noise:

The results are again simply excellent. Only compact liquid-cooling systems did a little bit better here in terms of temperatures, but they obviously lost to the new Phanteks PH-TC14PE in terms of noise. Nevertheless, I have to point out that NZXT Havik 140 and Thermalright Archon are capable of the same maximum CPU overclocking. Moreover, their noise level will be somewhat lower in this case, and this is what we are going to discuss next.
