Yes, I love heatsink fans, because without them, my Athlon Thunderbird would set my whole apartment on fire.
"There are a few major heatsink manufacturers which
produce the staples of the cooling world, and Globalwin is one of them. The CAK4-88T is an all copper skive heatsink with a thermally controlled 80mm fan for lower-noise sensitivity. When the heatsink is not very hot, the fan spins at a slower RPM which produces less noise. When the thermistor senses an increase in temperature, the fan speed kicks in to full RPM, and the heatsink receives an added boost necessary to keep temperatures under control. Since the copper skive portion of the Globalwin CAK4-88T is just 70mm in size, Globalwin have added an 80mm-70mm fan adaptor to the package. The fan adaptor is made from translucent blue plastic and features an ingenious curved divider down the center."
