In conclusion of this section we publish comparative diagrams of temperature readings and thermal resistance for nominal/reference configurations of today's contenders (maximum fan speed), a diagram with temperature readings of near-socket inductive elements (low-noise domain), as well as efficiency-noise ratings (low-noise and ergonomic domains).

Chart 7. Temperature readings (CPU core temperature, nominal/reference modes)

Chart 8. Thermal resistance (nominal/reference modes)

Chart 9. Temperature readings (temperature of near-socket components)

Chart 10. Efficiency/noise ratio


This product is a serious contender for the League of Bleeding-edge Air Coolers. It demonstrates decent results practically at all speeds, except for the noiseless mode. These results are worthy of High-End products, so it successfully competes with many famous rivals from leading cooler makers. Our only gripe is about its high retail price. It must be adjusted with regard to the current market situation. Save for this, the overall functionality of Silent Knight II makes it a very interesting product, which can provide ergonomic and efficient cooling for both Intel LGA775 and AMD Socket AM2 processors.

ASUS Silent Knight II cooler gets our Original Design award for original solutions used in its heatsink.

We wish ASUS success and new achievements in developing its High-End cooler series, preferably with more attractive price tags as all prerequisites are there. And we shall keep tabs on the situation in the high-end cooler segment.
