Fan Cable Products

Fan Speed Control Cable
The fans used in this case are the slowest speed available in a 70mm size. However, I prefer to run them even slower for reduced noise. Stock fan speed is 3300 RPM, this speed is fine for remote installations where noise is not a concern or where maximum cooling is desired. Advanced users can easily make/modify their own cables. Cable is just a standard fan extension cable with a resistor installed inline to reduce the current to the fan.

Note: There are many variables to optimum fan speed. You may want to run the fans faster with a hot video card. A cool running system can run the fans at slower speeds. For quiet cooling of your Radeon, see the Mass-Air Heatsink System.


Select Resistor Value
33 ohm
47 ohm
68 ohm
82 ohm
100 ohm

Recommended fan speeds:

  • 00 ohm  =  3300 RPM (>3 GHz)

  • 33 ohm  =  2500 RPM (2.8 - 3 GHz)

  • 47 ohm  =  2300 RPM (2.5 - 2.8 GHz)

  • 68 ohm  =  2000 RPM (2.0 - 2.5 GHz)

  • 82 ohm  =  1600 RPM (1.8 - 2.0 GHz)

  • 100 ohm = 1300 RPM (<1.8 GHz)

For lower noise, slower speeds can be used. Get a few sizes to see what works best in your system.

Fan Extension Cable

18" long 3-pin fan extension cable. Use this cable to extend the reach of your fan cable or to build your own fan speed cable.





Fan Splitter Cable

Use this cable to connect two case fans to a single three pin header. Allows two fans to be used with one fan speed controller. 3-pin connectors for fans with tach signal.
