Noctua NF-R8 and NF-S12 Cooling Fans
Published: 18th January 2007 | Source: Noctua | Price: |The Fans In Detail
Both the NF-S12 and NF-R8 Cooling fans utilise Noctua's SSO-Bearing in order to attain silent operation. The SSO-Bearing is a magnetically centred, self lubricating oil-pressure bearing that surpasses current types of ball, sleeve and liquid bearings in long-term stability and quietness thanks to its new, improved principle of operation. It is through the use of the SSO-Bearing that Noctua are able to provide a stellar 6 year warranty and impressive 150,000h MTBF. I have included an illustration of Noctua's SSO-Bearing to further reinforce the theory.
But don't just take my word for it, I'll let Noctua's technical information get the point across.
|"In order to make their products more silent, fan manufacturers usually simply reduce RPM without adapting the rotor design to the modified fluid dynamic parameters", explains Mag. Manfred Stadler MBA of the Austrian Institute for Heat-Transmission and Fan Technology. "Using a blade geometry specifically optimised for lower speed ranges like the Noctua Straight-Blade-Design allows for much better performance than simply reducing RPM."|
