Conclusion

Both the Arctic Cooling fans and the Noiseblocker fans are very capable of keeping your case cool while managing to keep things about as quiet as you can with active cooling. However, in terms of price, features and lack of dust build up the Arctic Cooling PWM fans win hands down. However, if you are after super silence throughout the RPM range, then the Noiseblocker fans are for you; just remember though, silence comes at a premium.

I'd like to thank our sponsors Arctic Cooling for providing us with these fans.
