iMacs and MacBooks use radial fans and you could say this is a radial fan too. However in this case the heatsink is it self the fan while macs use the normal fan with separate heatsink construction. BTW there are also PC notebooks and desktops with radial fans. Radial fans are in general quieter and are much better at building pressure so they are much better at pushing air through a heatsink. However they are more expensive.
