Test results, configurations with Scythe S-Flex and Minebea fans,
dual-fan assemblies. Bottom line

Along with the standard temperature tests run on the Scythe Ninja Plus Rev.B, Infinity, and Andy Samurai Master that are run with the stock YLT DFS122512L fan, we also are testing these coolers with popular Scythe fans of the S-Flex and Minebea series after also adding several dual-fan configurations for the Ninja Plus Rev.B and Infinity. Let's see what effect on performance changing the cooler fan has.

Summary diagrams with noise characteristics and noise/efficiency ratings

We have also taken a look at the noise levels of these coolers. The method of testing noise measurement and creating the efficiency/noise rating of coolers.is described in the article Noise characteristics of coolers and the noise measurement method.

Note:
Background noise level 18 dBA.

Note
The efficiency/noise ratio (ENR) is calculated as:

ENR = DM*(R_t/TC)/(NL/R_n), where

R_t - reference temperature (the reference thermal resistance θ_ja of the cooling system - 0.25°C/W), TC - the core temperature with the operating cooling system, R_n - reference noise (the reference noise level is 20 dBA), NL - noise level, generated by the cooling system, DM - denominate multiplier (10).

Conclusions

The Ninja Plus Rev.B, Infinity, and Andy Samurai Master coolers ace our tests and confirm the high-end status of Scythe products. We would like to specifically mention the Infinity model, which possesses an advanced and unique design that helps it achieve record after record in pure thermal terms as well as in overall functionality. The Ninja Plus Rev.B and Andy Samurai Master also perform quite well. The Ninja Plus Rev.B successfully improves the design of the Ninja series, and the Andy Samurai Master borrows many of its technologies from the Infinity. The Andy Samurai Master practically reaches the same results as the Infinity.

From our tests today, we feel that all the three of these coolers are able to handle the thermal load of all the hottest high-end processors from Intel and AMD, including quad-core models.

Scythe Infinity and Scythe Andy Samurai Master get our Original Design award.
