PC AirCon PAC400
Page 3 - Testing and Conclusion

During the testing phase, the PC AirCon 400 was installed on a computer with these specifications.

Test Computer
CPU AMD Athlon XP 2500+ @ 1.95Ghz
Memory Corsair TwinX 1024-4000 Pro Series RAM
Hard Drive Maxtor 80GB w/ 8MB Cache
Case Antec SX1040BII Performance Series
Fans Two Front, Two Back


With two fans already present in the front of the case, no temperature changes were evident (using Asus Probe) when the unit was set to "Fan". More disappointing was the fact that no temperature changes were evident when the unit was set to "Snow". On further inspection, I noticed that there was only a faint stream of cool air being sent from the interior of the AirCon. As a result, any wire clutter surrounding that area serves as a potential airflow inhibitor.

However, when the wire clutter was fixed no temperature changes occurred. The volume of the cool air was not substantial enough to alter the overall temperature of the system. Furthermore, with two other front fans blowing in warmer air, the small volume of cool air introduced by the PC AirCon becomes negligible when mixed with the warmer air.

An improvement I would like to see would be increased airflow into the system. Although two fans are pushing a considerable amount of air through the system (on "Snow" mode), they are directed at an angle relative to the vent for air. Also, the natural shape of the heatsink obstructs the natural flow of air delivered by the fans, thus reducing the airflow to an almost undetectable amount. Whether this means adding another fan with the job of pushing the cool air through, or increasing the airflow volumes of the two fans, consumers will not invest in a product whose patented technology does no produce valuable results.

Due to the disappointing results listed above, I decided to test out the unit on a computer which had no extra cooling at all, just a rear exhaust fan.

Test Computer
CPU AMD Athlon XP 2000+
Memory Kingmax 512 DDR
Hard Drive Maxtor 80GB
Case Generic IBM Case
Fans 1 Back


With this setup, CPU temperature and motherboard temperature experienced a two degree drop when the unit was turned onto "Snow". This is quite substantial, since the this unit is cooling on a system-based level; not only are CPU and motherboard temperatures decreased, other peripherals inside the computer are cooler as well. However, not many consumers who shop for cooling products have computers which no cooling at all. If Waffer Technology wants to attract customers, its product needs to be able to perform on a wider range of computers, not just those who far left on the cooling spectrum.

In conclusion, Waffer Technology has presented us with a product that uses breakthrough technology that acts as an air conditioner for the computer. While all the concepts presented by the product are interesting, the product fails to deliver a significant amount of cool air into the computer. This results in an inability to substantially lower the temperature of the system. If the changes listed above can be made, the PC AirCon will surely be a headliner for future state-of-the-art cooling technology.

Final Score
