Downvolting

[Arinoth]

I have some fans that run too fast and i want to down volt them. Now i have a few options

Or 'jimmy rigging' my own, the one thing with this one is i am not sure which kind of potentiometer to use as i dont know the wattage these fans can pull http://www.ncix.com/products/?sku=42...tech.com%20Ltd

What do you all think, im looking for the least expensive and safest.

You can get the above item for manually adjusting the fan speeds. Also, these things come with the GELID Wing series fans.

The fan in question does not have a 3-pin, it has molex connectors

Couldn't you get an adapter or something?

If i do that then it kinda leads into the cost of one of the two items i've listed. I'm contemplating the third option using a pot aka voltage divider but i don't know what fans are rated to run at wattage wise as i don't want to blow a resistor/pot by running it at a wattage its not designed for.

Fans typically have a current rating listed on the label covering the hub.

i would actually rig them to a controller. a bit more expensive, but adjusting the speed would blow whatever savings the other solutions offer :)

You obviously don't know what a potentiometer is. This is it:


It is exactly what are in fan controllers except you dont have the knob on them, they aren't pre-wired or in a fancy package.

Most fan controllers now use PWM circuits instead.

Well from the grainy picture from startech's website I could make out 0.04 A.
