im going to be using a gelid wing 12 volt computer fan as a exhaust fan for a kids outdoor playhouse. i know how to hook the fan straight to the 12 volt cell phone charger, but not with the fan speed control that it comes with. here are the color codes of the fan . the fan itself has a red,yellow. and a black wire. that connects into the fan speed control. the end of the fan speed control has a three prong female adaptor where you are suppose to run everything to. the color of the three wires at the end of the fan speed control with a three prong female plug in, are adaptor, not sure whats its called, has a yellow,red and grey wire. how can i connect this to the two wires on the cell phone charger so that the fan speed control works? it works fine without connecting the fan speed control. just don't know how to make it work with it?

can someone please tell me how the wires go. i have two wires from a 12v plug( old cell phone charger), and two wires from a 12v fan. i just want the fan to turn on when it gets to hot in child playhouse. using it to let the hot air from ceiling out. The thermostat control has 5 connecting pins you can solder wires to. they say 12v positive,12v negative,nc,com,no. just need to know how to hook up the wires from the plug and fan I have to this. here is the link - http://www.futurekit.com/2009/index.php?option=com_content&task=view&id=1249&Itemid=5 . if you click on the picture it gets larger so you can see the pins were wires can be soldered. pin are all on one side in a line.

Detail:
This circuit is a measurement of temperature.
It has cut-off circuit when the lower or higher temperature varie 2˚C from your setting.
It can be set to detect the temperature from 0˚ TO 100˚C.
Used IC LM335Z is the detector temperature.
The temperature range can be adjusted be potentiometer.

This does not sound like what you want. I suggest something like this.

Thermostatic Outlets
Thermostatic Outlet Need an inexpensive and simple thermostat? Thermostatic outlets are the answer. These unique devices plug into a standard electrical outlet and have an internal preset thermostat. Outlets come in two models. The Cooling outlet supplies power at 78 and cuts off at 70 and works great for all types of fans including exhaust, circulation, window, attic, and ceiling fans. The Heating outlet supplies power at 35 and cuts off at 45 and is great for automating heaters to keep room temperatures above freezing. Each outlet has two receptacles and can be used with 110/120 volt outlets and appliances (15 amp/110v).

Then just plug the ac adapter into it and done. Also if the fan you try is not biog enough this can also control a AC fan.

If you are in the UK or a 240 Volt area you would have to find a unit suitable for the Mains voltage there as this example is for the USA line voltage.

Good Luck

Why would you want speed control? Such a fan will achieve pretty much nothing at full speed, there would be no value at all in having it run slower.
