Quietly does it |

ADDA has introduced low speed versions to many DC fans to cater for the growing need of the PC ’silencing’ market. DC fans in the 40 to 92mm frame size range are used to cool PCs but in the standard form these are too noisy for the comfort of most users and a slower fan would normally suffice in all except the most demanding of applications.
The new low-speed versions from ADDA, available exclusively in the UK from Aerco, make a real, practical difference to noise levels, the comfort of users and the life cycle of PCs.
For instance, the low speed version of the 40x40x20mm fan has an operating noise level of 23.9dB/A compared with the 31.9dB(A) of the standard version while delivering 3.53 litre/sec (7.5 CFM). In the 80x80x25mm range the low speed version operates at only 15dB(A) compared with the 40dB(A) of some fans in the same frame size and yet delivers 9.68 litre/sec (20.5 CFM).
ADDA DC fans are available with ball, sleeve or HYPRO bearings and can be used as the cooling element in intelligent cooling systems. |
