Is the fan speed dial a POT or is it a Rheostat?

If a POT, then does the fan speed increase with less resistance at the
POT or more resistance? (a thermistor could be added or even replace the
dial if it works the same way)

Any other comments on noise/cooling appreciated also.

Aero 7 lite is cheaper and according to many reviews also a better cooler.
The sound is more tolerable at high speeds than other fans because of it's
type (lower pitched) but still can get annoying...

What the heck is the difference between a Pot and a Rheostat? I've
always thought they were the same thing.

I would think that dialing up the resistance would drop the voltage at
the motor, and slow it down.

A rheostat has two terminals; a potentiometer has 3. At least that
used to be true; they may have joined the long list of words that have
become ambiguous.

No, they're different. A rheostat has 1 inout and 1 output with resistance
in between. A pot, well this is easier.

potentiometer

1 Manually adjustable, variable, electrical resistor. It has a resistance
element that is attached to the circuit by three contacts, or terminals.
The ends of the resistance element are attached to two input voltage
conductors of the circuit, and the third contact, attached to the output
of the circuit, is usually a movable terminal that slides across the
resistance element, effectively dividing it into two resistors. Since the
position of the movable terminal determines what percentage of the input
voltage will actually be applied to the circuit, the potentiometer can be
used to vary the magnitude of the voltage; for this reason it is sometimes
called a voltage divider. Typical uses of potentiometers are in radio
volume controls and television brightness controls. 2 Device used to make
a precise determination of the electromotive force, or maximum output
voltage, of a cell or generator by comparing it with a known voltage.
