[TenTec] Delta II Cooling Fan

[KE4TEG]

Hello Mitch,

Why fight nature? If mounting the fans below the heatsink have the fan
blowing up through the heatsink (my preferred way). If mounting above, have
the fan pull air through the heatsink blowing up into the open air (I do not
care for this setup because the muffin fan blocks the nature heat rise). And
yes the fan more then makes up for this, but I still do not care for it. If
mounted on the rear of the heatsink, have the fan blowing into the heatsink.
This again keeps the exhaust heat flowing in the nature direction. Why fight
against nature when you can help nature.

Just my three cents,

Keith

blowing cool air onto the heat sink, or drawing the heat away?  In other
words, blowing in or blowing out ?  I have muffin fans on the top of my amp
drawing the air out of the tube chimneys -- same principal for heat sinks,
or not?
