The main point on interest on this device is a potentiometer which can be adjusted with a small screwdriver. This varies the voltage going to the TECs, and thus affects their performance. The only real point of doing this is to control the amount of noise the unit produces, we found a clever way around that, though. The potentiometer can affect fan speed, and thus noise, only if the fan is plugged into it and not the motherboard. We just plugged it into the motherboard and ran the Freezone at full blast with no real sound problems. In fact, it was quiet as a mouse. The entire unit, once installed, was not intrusive at all, and really added to the style of the case due to CoolIt's design.

Once we had everything wired up, which took us a while since the Freezone has 4 different bundles of wires coming from it, we started our tests.

Before we get to any gaming benchmarks, it’s of course important to measure the idle and load temperatures, as well as find out how fast we could even get our computer with this setup. Our test bed is as follows:

• AMD Athlon 4200+ (2.2GHz, 1.35V stock)
• Abit KN8 SLI
• eVGA 7800GT
• Corsair XMS Pro PC3500
• Antec TruPower550
• Coolermaster CM Stacker 810
• 8x 320GB Western Digital HDs
• Areca ARC-1230
• Sound Blaster Audigy 2
• Leadtek Winfast TV2000 XP Expert
