Testing Results: Maximum Fan Speed

To start things off, let's take a look at the peak cooling performance of our four tower coolers. We should note that the Phanteks PH-TC14S is once again the oddity of this review, with its fan reaching 1520 RPM. The specifications of the PH-F140HP fan state a very broad maximum speed range of 1300 ± 250 RPM, so our reading is within the fan’s specifications, yet this is the first time that we have encountered a fan spinning that much faster than its rated speed.

With their fans running at their maximum speed, the best overall thermal performance comes from Thermalright’s True Spirit 140 Direct. Noctua’s NH-U14S handles high loads a little better, but Thermalright’s offering has a very strong advantage at lower loads, suggesting more efficient heat transfer due to its direct contact design. 

The Be Quiet! Shadow Rock Slim falls a little behind in terms of thermal performance but only by a couple of degrees, which is acceptable considering that it had the lowest noise reading of this review. Considering the overall design of the cooler and that it has a smaller number of heatpipes in comparison to every other cooler in this review, its top speed performance is surprisingly good.

Although its thermal performance is satisfactory, the Phanteks PH-TC14S falls behind the other three coolers of this review. It is both slightly louder and less efficient, especially when it has to deal with very high thermal loads. The difference however is small and a more carefully designed revision can easily turn the tables.

Testing Results: Low Fan Speed

As most users don't actually need the fans of a tower cooler running at peak performance (and peak noise), let's also take a look at what kind of performance these coolers provide at lower fan speeds.

Broadly speaking, all four of the coolers that we tested for this review were capable of sustaining reasonable operating temperatures with thermal loads above 200 Watts, even with the speed of their fans greatly reduced.

There are virtually no differences between these four coolers in relation to our previous test, with the Thermalright True Spirit 140 Direct again displaying the best overall thermal resistance and excellent efficiency with the handling of low thermal loads. However, the Noctua NH-U14S greatly outperforms all other coolers when it comes to the handling of very high thermal loads, suggesting that it can maintain reasonable operating temperatures on overclocked processors alongside with virtually inaudible noise levels.

Once again, the Be Quiet! Shadow Rock Slim falls slightly behind the Noctua NH-U14S and the Thermalright True Spirit 140 Direct. The thermal resistance is only slightly worse but this time the Shadow Rock Slim also has no real advantage in terms of acoustics, as the difference between all four of the coolers is practically indiscernible.

Finally, the Phanteks PH-TC14S displayed the lowest overall performance figures, with slightly worse thermal resistance than all of the coolers in this roundup review. Although the Phanteks PH-TC14S displays thermal performance similar to that of the other coolers at lower loads, the difference widens greatly when the thermal load is very high, suggesting that the cooler is at its limit in handling the excessive thermal energy flow.
