New heatsink idea.

[nativepaul]

To get decent flow though a duct the inlet, its area has to be at least the same swept area of the fan blases. With the restriction of the blades creating narow channels you will need a lot more intake area than you have or the fan will be running stalled and have very little flow.


If you cut out channels in the sides as well as the ends something like this, it would triple the inlet area and restrict the flow a lot less.
