Cooling Efficiency Tests
The results of our cooling efficiency tests are summed up in the diagram and table below:
With default cooling fans Titan Fenrir Siberia Edition loses without a fight to Phanteks PH-TC14PE. Moreover, even at the maximum rotation speed of its two fans (1900/2270 RPM) it is still 4°C behind Phanteks PH-TC14PE with the fans rotating at 800 ROM. If we check out the peak CPU temperatures when the fans on both coolers rotate at the same exact speed, then the new Titan cooler will be as much as 14°C behind Phanteks. I have to admit that it isn’t an encouraging result for a cooler of this price. This is indeed unfortunate, but maybe the new Titan Fenrir Siberia Edition will do better with alternative 140 mm fans from Scythe?
True, two identical Slit Stream 140 fans improved the cooling efficiency of Titan Fenrir Siberia Edition. It still lost to the Phanteks cooler, but at the low rotation speeds of 800 and 1000 RPM the cooler started cooling 2-4°C better, at 1200 and 1400 RPM – 1-2°C better, and at the maximum speed of 1700 RPM – 2°C better. It isn’t much, but it is still noticeably better than the results obtained with the original default Titan Kukri fans. Phanteks PH-TC14PE is still 6-7°C more efficient than Fenrir Siberia Edition.
Now let’s see how Titan Fenrir Siberia Edition will rank, if we add it to our database diagram and table*, where all coolers are entered in their default configurations. We will add the results in quiet mode (800/890 RPM) and at maximum speed of both fans (1900/2270 RPM) when the CPU was overclocked to 4.375 GHz at 1.385 V core voltage:
In quiet mode the 90-dollar cooler appears to be in the very last place behind all other products, which we have already tested on the new LGA 2011 platform. At the maximum fan rotation speed Titan Fenrir Siberia Edition managed to settle somewhere in the middle of the pack showing 1°C better result than Thermalright HR-02 Macho with one TY-140 fan.
During the maximum overclocking tests, Titan Fenrir Siberia Edition maintained stability of our CPU overclocked to 4.5 GHz at 1.410 V core voltage and 80°C peak temperature:
The table and diagram with maximum CPU overclocking results under each of the coolers in their default configurations place Titan Fenrir Siberia Edition somewhere in the middle between Thermalright Archon with one TY-140 fan at 1260 RPM and Noctua NH-D14 SE2011 with two fans:
To be fair I have to say that both these coolers are quieter than Titan Fenrir Siberia Edition. So, why don’t we move on to the noise tests now?
