Globalwin CAK4-76T Copper Heatsink Review

With a thermistor controlled fan that ranges in noise from about 37 dB - 45 dB, the Globalwin CAK4-76T is one of the quieter heatsinks out on the market, but also one which will scale its speed to meet the cooling requirements placed on it. As the thermistor senses an increase in the temperature of the body of the heatsink it will increase the fan speed to compensate. This technique has been used for quite some time on power supplies where it was effective at decreasing the overall sound output of a computer.
