Inside the Cooler
Taking a look inside the cooler, you can see the overall layout.
At the front we have a 120mm fan that cools the condenser where the R507 is cooled.
The compressor was made by ZEL and was supposed to use R134a just like most modern cars. Like the Mach II GT, OCZ has chosen to use a better refrigerant to keep the CPU cooler.
Here we see the control board that is responsible for reading all of the sensors found on the Cryo-Z. I was not able to find additional information online for the unit, but it is listed as a Cooler Express Control.
Finally we see that the Cryo-Z has a built-in power supply to power the control board, LCD and sensors for the unit.
