Add a Case Fan to the Interior of the Computer Tower 1 Connect a case fan to an open space on the rear-inside panel of the computer case. Some computer towers will provide extra space on the rear panel of the case designed specifically to accommodate additional case fans. Attach the case fan to the vented, rear panel. Power down the computer and turn the power switch off on the power supply, which is typically situated on the back of the computer tower near the AC power cord. Position the fan over the vented area. Line the screw holes in the fan up with the venting holes on the back of the case. Using a screwdriver, insert at least 4 screws into the corresponding holes in each corner of the case fan. Connect the fan to the power supply.

Two “thru-core” connectors would be needed to secure the top of the fan shroud against the radiator.. To insure a good seal at the edges of the new shroud we used foam weather seal you can find at any hardware store. The pictures tell the story. It will also protect the radiator from rubbing due to vibration. With the fan in place we connected the cut harness we saved and tried out the fan by going across the battery with the bare ends of the wires.

The low speed wire contacted the battery post and the fan spun up quickly.

Nov 20,  · Add a fan There is a connection on the Stepoko for attaching a single, or multiple 12V fans. This connection is regulated to 12V and unswitched, so fans connected there will run whenever the Stepoko is powered from V.

The controls for window units are simple and inbuilt, it includes: Then go through raceway system conduits, ducts, … to a disconnect means of some type suitable for the application. The ground wire either green or a bare wire is screwed to the metal casing of the unit. Hot wire Neutral wire. B- Hot wire goes to the selector switch on a window unit to feed power to the vital parts, compressor and fan motor as follows: Hot wire to selector switch to thermostat switch to compressor Hot wire to selector switch to fan motor.

C- Neutral wire will be connected to fan motor and compressor without goes through any switch. These connections are made on the wire connector in the back of the selector switch so, all neutral wires are common to each other because they are connected to the same point.


Various methods of control are employed such as dampers, variable inlet vanes, variable pitch blades or variable speed to meet other operating points defined by the system duty cycle. This may even include an allowance for future expansions. Sometimes it is advantageous to use more than one fan in a system.

I replaced my old working ceiling fan with a new one. The control is a dimmer with a rocker switch and was not changed out. The ceiling box has only 2 white wires coming out and I duplicated the installation putting the blue and black to the same white as the old one and the white to the other.

Well, you do need 12V for the fan to really kick. Check the image on the link you provided again: Instead of fiddling around the motherboard you can splice the fan wiring with a free 4 or 3 pin molex adapter coming of your power supply unit. I’m explaining the more difficult and leaving a note on the easier: Remove the isolation of the end of both the Red and Black wires, thus exposing a little of the metal wire beneath.

Bend the tip of the exposed wire, producing a tiny U shape. Clean and isolate the white wire.

Fan Types A 2-wire fan has power and ground terminals. A 4-wire fan has power, ground, a tach output, and a PWM-drive input. PWM, in brief, uses the relative width of pulses in a train of on-off pulses to adjust the level of power applied to the motor. A 2-wire fan is controlled by adjusting either the dc voltage or pulse width in low-frequency PWM. However, with only two wires, a tach signal is not readily available.

It’s the classic tale of boy meets girl.. and another girl, and about five other boys, and a couple of homicidal girls, and a lot of machine guns and military vehicles.

In Figures 1 and 2 you can see a three- and a four-pin connector, respectively. Notice that the counting is done with the key present on the connector facing up. Connector from a CPU fan using three pins Figure 2: Connector from a CPU fan using four pins Figure 3: CPU fan connector on a motherboard, you can install either three- or four-pin fan connectors here The first two pins supply the voltage required for the fan to spin.

The third pin is connected to the fan speed sensor, reporting the current fan speed to the motherboard.


To remove an old fan, follow this procedure: Shut down the computer and unplug it. Note where the fan is connected to the computer motherboard, fourpin Molex power connector, or both.

Most likely, you will end up with a 12 volt dc fan, and will want to use a less involved method to make it compatible with ac. The fan voltage, etc. If a 12 volt dc fan, go to a thrift store and buy a 12 volt cell phone charger. If you get a 6 volt fan, buy a 6 volt charger, etc. Cut off the very end of the phone charger wire that ends in a square connector rather than a typical wall plug.

Then, use a wire splicer to remove the outer black coating. You should see one small red and one small black wire inside. Remove enough of the red and black coating that about an inch of metal is exposed for both wires. It should have at least one red and one black wire. Some differ, but generally, any green, yellow, or blue wires are sensors or for speed control and can be ignored. Strip the red and black wires until about an inch of metal is exposed for both.

give the case name and model same for the motherboard,and dont use more than 2 fan on the same header with a splitter on the motherboard. i presume your case must have a fan controller include.

Aug 25, 3-pin fans – the fan is controlled by voltage. I think that means fan speed is adjusted by some physical means, such as a knob to turn. It’s not possible to adjust the fan speed through the motherboard i. Speedfan, bios, other software won’t have any affect on the speed fan. True most of the time. Server boards in particular, Abit boards had they are in process of being out of business excellent fan speed control through the bios.

Also in the bios of some boards for the CPU fan – there is a “Legacy” fan speed control setting that will adjust the CPU fan speed by voltage control in case you do not use a CPU heatsink with a pwm 4 pin fan. Say a 3rd party heatsink in which you supply your own fan and it is 3 pin. Motherboard header is 4 pin. These are useful for rear exhaust fans. Some work really well, and some are crap as they dont rev up until it is IMO too damn hot.

These dont work well for intake fans as the room air is usually always so cool, even in summer, the fans run at their lowest speed. Other thoughts, you can plug a 3 pin fan into a 4 pin motherboard header. You cannot plug a 4 pin pwm fan into a 3 pin fan header – will not run.
