What is TEC
TEC, which stands for "Thermal Electric Cooling", is based on the Peltier Effect. It was first discovered in the early 19th century.
DC current passes through the thermo-electric device causing heat to be absorbed at one side and releasing to the opposite side during operation.
One Slot card
SubZero4G is designed for PC users who need lower noise level and improved performance. SubZero4G TM comprises a cooling unit, a PCI card (power and control unit) and a LED case fan.
The cooling unit consists of a cold plate, a thermo-electric module, a heat sink, and a CPU fan. The cold plate is directly mounted on the CPU. The thermo-electric module carries the heat from the cold plate to the heat sink. The CPU fan takes away the heat and case fans remove the heat to outside the case.
The PCI card includes an AC/DC power supply and a microprocessor. The microprocessor detects the temperature by ambient and CPU temperature sensors and then outputs adequate power to CPU and case fans. In short, the 3-step fan speed is controlled by the microprocessor.
Noise Control
3-step fan speed controlled by microprocessor.Physics of TEC unit makes it possible to reduce noise without compromising cooling.
How thermo-electric effect reduces fan noise without compromising cooling
In a conventional cooler, the CPU is in direct contact with the heat sink. If fan speed is reduced, the heat sink will become hotter. The CPU, which is in contact with the heat sink, will also become hotter.
In contrast, in a TEC cooler, the CPU is isolated from the heatsink by the thermo-electric unit (a solid-state heat pump). If fan speed is reduced, the heat sink will become hotter. But the thermo-electric unit continues to pump heat from the CPU to the heatsink. Noise can be reduced while maintaining the same level of cooling of the CPU. This is not possible with conventional air cooling.
