How to slow 120mm fans down?

Rain Man · 27 May 2006 at 00:41

ive got two 120mm intake fans on my lian li pc v1000 which are a bit noisy for my liking

I remember seeing somewhere that you can mod them to make them use less voltage, ie slower quieter fans.

Anyone know this?

cheers

Cut the wires, find yourself a molex, solder on red and black. WOLLA! Now your fans are running at 5V

If they are 3pin you could just use a molex adapter (3-4 pin) and mod the adapter itself, if they are already molex then theres a guide in the case central sticky.

If they are 3 pin than connect them to your mobo and use SpeedFan to control them.

easy peasy ...

tiny screwdriver, takes a while, but once you get the hang of the pins, its easy

Who are you btw?

Mekrel · 29 May 2006 at 22:23

With the Akasa 3pin cable which reduces the volts to 10v - surely you would have setup your motherboard to supply a constant 12v to the fans. As some motherboards use PWMIC to control fans according to temperature.
