We measured the amount of noise produced by the coolers throughout the speed range of their fans. You can view the results in the following diagram:
The Thermalright Silver Arrow SB-E is obviously quieter than the Phanteks PH-TC14PE irrespective of the number of fans. That’s a very important factor for super-coolers. The two fans of the Silver Arrow SB-E are comfortable up to 950 RPM while the Phanteks with its single fan is only comfortable up to 800 RPM. Compared to that, the Thermalright’s fans are only 33 dBA loud at 800 RPM. Thus, the Thermalright cooler is surely the better of the two in terms of acoustic comfort.
Can we say that the Thermalright Silver Arrow SB-E is the best air cooler for Intel’s Sandy Bridge-E processors? Well, we don’t really know. The Phanteks PH-TC14PE is 1-2°C better in sheer performance and can also keep our overclocked CPU stable at a higher frequency and voltage. However, the Silver Arrow SB-E is undoubtedly superior in terms of the noise/performance ratio thanks to its high-quality and quiet TY series fans.
These two coolers are identical in such parameters as size, mass, compatibility, ease of installation, reliability and price. As for availability, Thermalright’s products are more widespread than those of the young firm Phanteks. The exterior design is just a matter of taste, although we’d prefer the Thermalright for its shiny looks.
So, the two coolers are roughly equal to each other and it’s up for you to choose! However, we believe that the new Thermalright Silver Arrow SB-E definitely deserves our Editor's Choice title:
