I started using after-market fans several years ago for both better cooling and lower (quieter) fan-speeds that result from using larger-diameter fans. The bigger diameter of the fan the bigger diameter is the spindle, the bigger is the 'dead spot' where no air is being blown -- and this is also the where the heat-dissipating part of the cpu under the heatsink is located.
With small fans used in computer the spindle (motor, bearings) is usually the same or almost the same size. The trick is that bigger diameter propeller will rotate slower with the same size motor anyway, but due to better efficiency of longer blades it will blow more air instead of blowing user ear drums. Second, I haven't seen CPU cooling solution with bigger fan and no funnel to keep that air flowing to CPU, not somewhere in that direction.
Many don't have a funnel, but they have a long-enough stand-off that the dead-spot doesn't reach the heat sink anyways. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
