You can see the results of our tests in this table as well as in the following diagram:
The Thermalright Archon SB-E X2 does improve the standing of single-tower coolers in their competition with dual-tower ones. At the maximum speed of their fans, the Archon SB-E X2 is as good as the Phanteks PH-TC14P? and even better in terms of minimum CPU temperature in idle mode. When the two TY-141 fans are slowed down by 200 RPM, the Archon remains as efficient as before, stopping a mere 1°C short of the best result. The further reduction of speed by 200 RPM, to 1000 RPM, makes the temperature rise by 2°C to 74°C. The Phanteks PH-TC14P? can deliver the same performance at 800 RPM, so the best air cooler is ahead here in terms of noisiness as we’ll show you later on.
At 800 RPM the Archon SB-E X2 allows the temperature to rise by 3°C more, yet remains 2°C ahead of its predecessor, the Archon SB-E with one TY-150 fan. Comparing these two versions, the X2 is definitely better thanks to its two fans (even though they are smaller now) and the fastening mechanism with adjustable pressure force.
Replacing the default Thermalright TY-141 fans with two Corsair AF140 fans didn’t improve the performance of the Archon SB-E X2, despite the difference in speed. We can also see that the Archon SB-E X2 is inferior at peak load to the Phanteks PH-TC14P? if both are equipped with the same fans: by 2°C at 1150 RPM and 950 RPM and by 4°C at 800. The Phanteks is larger than the Thermalright in terms of its heatsink area, hence the difference, the other factors being identical.
You can compare the new Archon’s performance with products we tested previously in the following table and diagram. Each cooler was tested in its default configuration at the maximum speed of the fan(s) with the CPU overclocked to 4.375 MHz at a voltage of 1.385 volts:
As in the main diagram with test results, the Thermalright Archon SB-E X2 is at the very top, almost beating the Phanteks PH-TC14P? in performance and being even quieter than the latter (with default fans). At a speed of 800 RPM the Archon SB-E X2 is better than the Silver Arrow SB-E, becoming one of the best coolers for quiet mode. It is only surpassed by the Phanteks PH-TC14P? with two default fans at 800 RPM but the latter produces more noise.
Next we tried to overclock our CPU with the Archon SB-E X2 as high as possible and reached a clock rate of 4.5 GHz at a voltage of 1.435 volts. The peak temperature of the hottest CPU core was 77°C:
Thermalright Archon SB-E X2,
2 TY-141 @ 1400 RPM
2 AF140 @ 1110 RPM
The Phanteks PH-TC14P? copes with the CPU easily, keeping the temperature lower by 2°C. We couldn’t make our CPU stable with the Archon SB-E X2 at a higher CPU frequency and voltage.
As a result, the Thermalright Archon SB-E X2 takes one of the leading positions in the middle group in terms of maximum CPU overclocking:
