Noiseblockers adds seal ring to its MultiFrame fans to improve performance

Cooling solution provide Noiseblocker has announced an update or upgrade to its MultiFrame series of case fans that is supposed to make them a bit more efficient and better suited for use in watercooling setups.

The update consists in the use of a sleeving ring that basically closes up the zones around the exterior of the fan through which air could slip through. The seal adds a bit to the performance delivered but doesn't affect the sound output.
