Six Best Coolers with Identical Fans

Well, now that we have arranged the coolers in order of efficiency when tested in their default configurations (or equipped with related fans), it is time to run the tests with identical fans and find the most efficient heatsink among our today’s testing participants. However, since there are way too many coolers in our race, we decided to test only six best of them here.

We chose Silverstone FM123 fans for our next test:

These fans have a rotation speed controller: their rotation speed may be adjusted from 900 (±90) to 2600 (±260) RPM creating 40.7-106.3CFM airflow and 0.66-4.55mmH2O static pressure. The fans were installed for intake-exhaust with the airflow directed towards the top of the case:

Since it is not very smart to run the tests at 2600RPM fan rotation speed with the closed system case, we removed the side panel for the entire test session:

Unlike all other coolers, Thermalright IFX-14 can accommodate not just one or two but three fans at the same time, and these can be not just 120x25(38)mm fans, but also 140x25mm fans. Since we didn’t have three identical Silverstone FM123 fans at our disposal, we installed three 140-mm Scythe Kaze Maru fans on it.

  

Quite a monster, isn’t it? All fans worked at 1260RPM rotation speed. Now let’s check out the obtained results:

Here is the screenshot of the best test result:

Once you check out the results, you ask yourself: if we call all 13 participating cooling solutions “super coolers”, then what shall we call Thermalright IFX-14? An “ultra cooler”? The CPU core voltage and frequency are higher, while the temperature is still lower than by other five contestants. Among them we would like to point out Scythe Mugen 2 and ThermoLab BARAM as offering the best feature and efficiency combination. Other coolers, however, also didn’t fall too far behind.
