UltraSilent series 80mm fans

	Fan speed (rpm)	Loudness (dB)	Airflow (m3/h)
UltraSilent series S1	1500	11	38
UltraSilent series S2	2000	19	50
UltraSilent series S3	2600	26	65
UltraSilent series S4	3200	32	75

The UltraSilent series are the high quality series from Noiseblocker which feature clear frames and blue fan blades. Noiseblocker offers their 80mm UltraSilent fans at speeds ranging from 1500RPM up to 3200RPM. The S1 1500RPM fan is entirely silent and the S2 2000RPM fan can be heard only if you place your ear next to it. The S4 3200RPM fan is clearly audible to the point it would be annoying for many, but it is a very high performance fan. The S3 2600RPM is a "middle ground" fan with decent air flow while remaining reasonably quiet, so using such a fan on a CPU cooler should in theory be ideal.


Noiseblocker also offer most of their fans in retail packaging, this includes 4 blue vibration absorber slicks and a fan controller which can be attached at a PCI slot. We received a retail version of the UltraSilent S1 fan, which is the same as the S1 described above. We found the fan controller to be entirely useless when paired with such a slow fan, why would you turn it down if you already cannot hear it anyway? On the other hand, the fan controller and anti-vibration slicks should be very useful additions to the high speed fans of the series.

BlackSilent series 80mm fans

	Fan speed (rpm)	Loudness (dB)	Airflow (m3/h)
BlackSilent series X1	1300	10	28
BlackSilent series X2	1800	18	45

The BlackSilent series from Noiseblocker are designed with silence in mind and cost less than half of the UltraSilent series and feature black frames and blue blades. They tend to be quieter than the UltraSilent series, but also perform slightly worse and come with only a 2 year warranty. The X1 and X2 fans which we received are good fans, extremely silent but with limited airflow. Since they are very silent and cheap they should be a very interesting choice for case fans when building a silent PC. 

UltraSilent series 92mm fans 

	Fan speed (rpm)	Loudness (dB)	Airflow (m3/h)
UltraSilent series SE1	1500	19	50
UltraSilent series SE2	1850	22	65

The UltraSilent series are the high quality series from Noiseblocker. They feature clear frames and blue fan blades. Noiseblocker offers their 80mm UltraSilent fans at speeds ranging from 1500RPM up to 1850RPM, both of the 92mm fans which we received were very silent. The SE1 could not be noticed at 1m range but we could notice the hum from the SE2 in a completely silent room. A common problem with 92mm fans is vibration, which is mainly why manufacturers avoid using 92mm fan slots in cases, but we were glad to find out that these two generated almost no vibrations at all.
