If you have a really good heatsink, the fan doesn't have to go nearly so
fast. The better the fan and the slower the fan the quieter the fan.

The better heatsink with a good quiet fan, then the CPU is cooler, which
is also better.

In a perfect world, everything would be quiet and cool :-)

There you go:

Cool, quiet, and not too expensive.
I've put a fair few Freezer 7's in PC's for people - no dissatisfied
customers yet.

Yes, but they are matched and sold together.

It blows air through the heatsink fins, that cools the heatsink.
Without quickly removing the hot air from between the heatsink
fins, the heatsink could not transfer enough heat away from the
CPU.

Removing the fan would prove otherwise.

Some CPU coolers include heat pipes that efficiently and/or
quickly move heat from the CPU to the heatsink fins. But the fan
is still necessary to quickly remove the hot air from between the
heatsink fins.

The bigger and better the heatsink, the less airflow you need, but
a CPU generates so much heat that a fan is necessary (of course
there could be some exception).

The quieter, the bigger.

How about this one. Theta_R is about 0.2C/W so this is a bit better than
some of the stock coolers might be. It uses a thin fan, and you can change
out the fan and use a regular fan if you want to (like a regular 25mm high
fan). The measured noise is pretty good (you have to compare its position
in the list of other coolers, to decide that - you can't rely on an absolute
number as everyone measures noise differently).

"Optional Fan Mounting
Optional 92 mm fan attachment is possible by using the included fan clip
for more performance."

I couldn't find a manual. It probably clips onto the center tab
of the CPU socket on each side.

The Freezer 7 Pro uses a 92mm fan that stands on its side.
