Noise

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 TRUE Spirit 140 has the quietest fan, the TY-140 once again proving its best-in-class combination of speed and noise. On the other hand, we have to admit that the quality of TY-140 fans varies from sample to sample, and we seem to have got a high-quality one this time around. The large TY-150 which is installed on the Archon SB-E and the second-revision Archon is inferior to the TY-140 in terms of acoustic comfort. The TY-150 is only comfortable until 880 RPM and quiet up to 750 RPM. The Xigmatek’s noise graph lies between the graphs of the two Thermalright fans. We can’t say anything bad about it. It’s just a good fan that remains quiet up to 840 RPM and comfortable up to 960 RPM.

Conclusion

With its average performance and noisiness, the Xigmatek Prime can hardly match the more advanced products from Thermalright: TRUE Spirit 140, Archon SB-E and Archon. However, the test with two alternative fans proves that its heatsink has some potential. The versatile Prime with its simple and reliable fastening mechanism, original PWM-regulated fan and attractive packaging would be a good buy if it cost about $40 instead of $60. Priced as it is, the Prime can hardly make a competitive product.

The Thermalright TRUE Spirit 140, on the contrary, boasts an excellent combination of performance, price and noise level. Notwithstanding the lack of soldering and air flow optimizations in its heatsink, this cooler is a mere 1-3°C inferior to the original Archon but costs only half as much. Just a perfect choice for a thrifty overclocker!

Unfortunately, the new Archon SB-E didn’t live up to our expectations. Its 7mm heat pipes and 150mm fan couldn’t make it more efficient than the original Archon. Hopefully, Thermalright will optimize it further before launching into production.
