The depicted model looks just like the Targus brand coolerpad as sold at Staples. One of my local Staples had a sale on them for $19.99. The Targus brand is silvery plastic and had no external power supply (powered by usb). There were instructions for using an external universal power supply (they identified the voltage and tip polarity needed).
There are several advantages of the Targus one over a number of other models such as the plastic one in the Anandtech forums about five years ago for approx $8.99 shipped (of which I bought two of them). The Targus one is a rare type that you can use on a soft surface. It sucks the air downwards from the bottom of the laptop and exhausts it out of the side opening. So, you can sit it on a soft surface or your lap without a problem. Most other laptop coolers require that they be placed on a hard surface because the fan blows downward and is also exposed. So, if you sat it on your lap, your legs would be right in the fan blades or obstructing the air passage at the bottom of the pad.
Comparison:
(1) anandtech hot deals special 5 years ago: acrylic plastic, two fans, on/off, requires hard surface, cannot be used on lap due to fan exposure and sharp edges digging into leg, air exhausted from bottom of pad and blows upwards onto laptop. Uses least power of the choices (1), (2), or (3).
(2) anandtech hot deals current special: plastic, two fans, on/off, can be used on lap or bed, air is sucked from bottom of laptop and exhausted to side opening. Have not experimented with the current draw.
(3) Antec old version (staples or compusa): plastic/aluminum, two fans, on/off, can be used on lap but not on bed. Use on lap partially but not completely obstructs fan openings. Doesn't use so much current that it prevents use of a self-powered USB hub AND the microsoft wireless mouse although its printed specs show it runs right to the edge of the USB current limit.
(4) Antec new version (Fry's Electronics): improved because the fans have adjustable speed to satisfy your desire for noise level. Have not bought one yet.
I have used (1), (2), and (3) but not (4) although I am thinking about it due to the noise level.... The 5V fans run full speed and it is clear that full speed is not necessary to cool the Pentium M laptop.
