Interpreting C/W: For every watt (CPUw) that the CPU consumes, the HSF will limit the CPU's temperature rise to (C/W x CPUw) plus the temperature at the HSF's fan inlet. For example, at an ambient temp of 25 C, a C/W of 0.25 with a CPU radiating 50 watts means that CPU temp will increase 50 x 0.25 = 12.5 C over ambient temp, or 37.5 C. The lower the C/W, the better.

Variables to consider in air cooling (total C/W)

- Heatsink
- Air velocity (fan)
- Air inlet temp
- TIM C/W

Variables for W/C

- Radiator
- Pump
- Radiator environment temp
- TIM C/W
- Block
- Air velocity (heat exchange to radiator)
- Air bubbles in system

Variables = Excitment in life;)

More excitement, the in house reviews:
