Specifications
Here are some key features
of the Cooler Master Ultra Vortex. The information was
grabbed from the Cooler Master website.
|
1. Unidirectional fin
heatsink provides
maximum heat dissipation
area and surround
cooling - unlike
traditional heat sinks. |
|
2. Curved copper fins
allow airflow to create
vortex filaments that
blow towards the fin
root, thus enhancing air
convection. |
|
3. The fins stamped on
the cone-shaped copper
slug allow smoother air
convection and give
shorter heat conducting
distance, providing much
better performance. |
|
4. Uses a 9 cm circular
fan with larger fan
blades than the
traditional rectangular
fan, providing more
airflow and better air
pressure. |
|
5. Ultra silent, only
16dB of noise level at
the lowest. |
|
6. Supports P4 in all
frequencies and K8. |

Notice that the fan is more than
whisper quiet at its lowest RPM. It only produces 16.6 dBA at a mere
1400 RPM and produces a pretty impressive 26.84 CFM. That's pretty
good considering it makes no audible noise. Turning up the fan
will result in a louder pitch, but it is definitely far from being
annoying. Running at 3000 RPM and producing 33.2 dBA is pretty
much the results of a typical case fan.
The package stated that the fan would
have a 3 pin RPM monitor along with a 4 pin power connector.
Unfortunately, the heatsink I received didn't conform to the stated
specs. The Ultra Vortex I had came with a single 3 pin power
connector. It would be unwise to connect the 3 pin power connector
to the motherboard as the fan at high RPM can draw too much current than
what the motherboard can handle, resulting in a fried fan header.
