The Auras SMF-660 heatsink is one of those heavy-weight cooling solutions that fear neither the 65-nanometer behemoths with a thermal envelope that would make a room heater red with envy, not the 45-nanometer war machines that may rest into your computer case.

The SMF-660 heatsink ships with its 92-millimeter Pulse Width Modulation (PWM) fan that can spin at between 1200-2100 rotations per minute (RPM), depending on the ambient and the CPU core temperatures.

The PWM system allows the motherboard BIOS to directly control the fan and set its speed according to the system workload at that time. This way, the System is kept cool while under full load (and the fan works at full speed), and quiet when the system is idle.

The Auras SMF-660 TwinW heatsink has three heatpipes that conduct heat from the base to the special W-shaped aluminum fins . This strange shape is more than a visual stunt; it reduces noise as air is drawn in from one side of the heatsink and expelled out the other.

The whole design is compact and well-knit the 6-millimeter copper heatpipes go straight up from the base through the aluminum fins. The heatsink is comprised of three parts: two outer towers of aluminum with the "W-shape fin design" and the 92mm fan switched in the middle.

The base finish is an extremely important aspect, and generally it is the best indicator of the cooler's overall performance. The copper base of the Auras SMF-660 heatsink is 36x36mm and is perfectly finished. It does not have that kind of mirror finish you can see on those high-end coolers, but, at the same time, both Surface Finish and Surface Roughness values are above normal levels.

Unfortunately, the cooler can be used by Intel CPU owners only, since it can be mounted on LGA 775 sockets. The Mounting bracket is held in place with four screws. The first aluminum fin is situated at 27 millimeters above the base, so the unit can be mounted even on those motherboards that come with high capacitors surrounding the CPU socket.
