You can see the results of our tests in this table as well as in the following diagram:
Let’s first check the coolers out with their default fans. As a matter of fact, the new Archon SB-E doesn’t show us anything exceptional. At the maximum speed of the 150mm fan it is a mere 1°C better in terms of peak CPU temperature than the original Archon with 140mm TY-140 fan. At 800 RPM the Archon SB-E is 3°C more efficient than the Archon at the same speed. But if the latter's speed is increased from 800 to 1000 RPM, the Archon SB-E is 3°C worse. Running a little ahead, we can tell you that the original Archon is superior to the SB-E version in terms of noisiness.
The overall best air cooler Phanteks PH-TC14PE is far more efficient than either Archon even at the minimum speed of its two 140mm fans.
Equipped with two TY-150 fans, the two Archons are very close in performance, the SB-E version being just a little better, by 1°C at any speed. It's a shame the developers have reduced the number of heatsink fins in the Archon SB-E and thus reduced the total heat dissipation area, which is such an important factor at very high loads. We guess the Archon SB-E would certainly look better in comparison with its predecessor and might even compete with the Phanteks PH-TC14PE if it had the same surface area.
You can compare its performance with products we tested previously in the following table and diagram. Each cooler was tested in its default configuration with the CPU overclocked to 4.375 MHz at a voltage of 1.385 volts.
As you can see, the new Thermalright Archon SB-E is in the leading group, but doesn’t outperform the original Archon.
When we tried to overclock our CPU while cooling it with the Thermalright Archon SB-E in the latter’s default configuration (with one 150mm fan), we found the CPU capable of working at 4500 MHz and 1.435 volts. The peak temperature of the CPU was 81°C. That’s a good, yet not outstanding, result. Especially as the original Archon looks just as good as the new version in terms of maximum CPU clock rate.
