Conclusion

Both cooling solutions discussed today boast unique looks and fan highlighting. One of them, Thermaltake SpinQ ($55), is more of a modding cooler than a high-performance cooler for overclocking experiments. Moreover, acoustically uncomfortable noise generated by its turbine at 1200 RPM rotation speed seems to be its major drawback.

The second cooler, ASUS Royal Knight, boasts higher cooling efficiency at lower noise level than SpinQ. As for the tinkling of the heatsink plates, I agree to consider it the issue of our specific sample. However, this cooler is very hard to install, requires removing the mainboard from the system case to complete installation and is incompatible with some of the existing mainboard models. Moreover, ASUS Royal Knight is quite expensive ($60), which makes it hard to compete in this market, because there are quite a few more efficient and quieter coolers out there today.
