The unit is composed of the central TE (Thermo-Electric) chip and two heatsink-fan modules on each side. The air is cooled when it passes through the cold heatsinks and continues to flow throughout the components of the computer. While conventional fan modules take fresh and somewhat cooler air from the outside, Waffer Technology goes a step further and cools the air further before it enters the computer.

Once the computer is started the Blue LCD screen will turn on the unit, displaying the temperature of the air being sent into the computer. This temperature will vary depending on which mode the unit is set on.

The three settings, "Off", "Fan", and "Snow", represent the different cooling stages this unit can deliver. In "Fan" mode the unit turns on the lower fan, which only delivers non-conditioned air from the outside. A noticeable sound increase is heard, but is bearable. At this point in time the TE chip has not been used. As a result, the blue LED read a temperature of around 25 degrees Celsius, which is considerably cooler than the interior because it is reading the temperature of the air outside that it is moving inside.

When "Snow" mode is actived, the top fan turns on to deliver more air into the computer and to dissipate more of the heat generated by the TE Chip. For aesthetic purposes, the top fan is a blue LED fan, delivering a funky glow on the whole unit. Also, the noise increases considerably, with each fan pumping 37dB. While this noise increase may be an annoyance to some, it may as well possibly be the deciding factor in whether or not your computer is cool. Temperatures as low as 21 degrees Celsius were recorded from the air intake temperature probe.

Overall, the visual appearance of the PC AirCon is average; one cannot expect a very stylish design for a miniature air conditioner. The unit is also considerably heavy, and may be more suited for people who do not move their computers a lot. However, with the front drive bay bracket, the unit can be removed at any time if it does not need to be used.
