The transformer that I used for this was rated for 1.2A so everything should be fine. If your aim is to use the car fan (Running on DC (Direct Current)), to the house electricity (Which runs AC(Alternating Current)), you can achieve it by using a Power Converter. That can actually cause some problems, since many devices work differently as far as the power is concerned. Buy yourself a transformer that is large enough to power your fan. Bestek Corp. If the wires are the same color, you can use a multimeter to figure out the polarity. Note that your fan will have an input current rating that will probably be around .32A like mine. I am trying to get power from the wall switch for the fan and still have the wall switch work the wall outlet. Disconnect the two wires that attach it to the computer – one red, one black. The AC adapter for a tablet or laptop is the cable that you plug into the wall to charge your battery (it usually has a tiny light on it).

The CFM (Cubic Feet per Minute) of a fan defines how much air it can shift in a minute. Either the red or blue wire is just to tell your computer the speed at which the fan is running. I have a receiver for my surround sound system which gets burning hot when used for a long period of time. If it goes half as fast, it will have half the back emf. DC stands for "Direct Current", which is the kind of power produced by 12 volt batteries. Buy a small 12 volt DC power supply at places like Radio Shack. Verbal11, this is a good way to fry the fan. The first step is to turn the power off to the outlet. Here, the fan speed is typically controlled by increasing or decreasing the voltage over the power wire, as in the case of a common 2-wire fan. As long as the transformer is rated to output more current than this, your setup will work. Look online or at your local computer-repair shop for a plastic computer-cooling fan. I just removed my flair... New comments cannot be posted and votes cannot be cast, More posts from the AskElectronics community. Hoooly crap, didn't even know that existed! One that's quite slow already, and put that on a simple manual speed controller, so she can make it even slower (breezes not good.). And which inexpensive power supply/adapter/wall wart? You want to be mindful of how many things you are plugging in, and what they are. Cooling fan Includes a 12038 aluminum fan with 110v/125v power plug cord, two 120mm fan guards, and two sets of mounting screw set Computer fan designed for projects that requires cooling or ventilation; or as a replacement fan for various products. How to Install a Wall Outlet in a Three-Way Switch Circuit. Strip fan … Before deciding on a laptop or PC fan… Inside you will find two smaller insulated wires. http://www.ebay.com/itm/12V-5V-3-3V-9V-AC-DC-Power... http://www.ebay.com/itm/AC-Converter-Adapter-DC-12V-0-5A-Power-Supply-Charger-US-5-5mm-x-2-1mm-500mA-/350764061850?pt=LH_DefaultDomain_0&hash=item51ab2ad49a, i would add a capacitor parallel to the fan to smooth the voltage. Abbreviated as PS or P/S, a power supply or PSU (power supply unit) is a hardware component of a computer that supplies all other components with power. Those numbers full power numbers. I assume she could pick up an appropriate wall wart and splice the wires, but which wires to connect where? Press J to jump to the feed. However, all the fans I've looked at are powered by 3 pin or 4 pin power sources (powered from the computer internally). https://www.maketecheasier.com/intake-exhaust-fans-airflow-desktop-pc On a desktop, this is the power cable that runs between the computer case and the power source. All appliances and electronics have a mechanical switch or an electronic switch to turn them on and off, and knowing the difference between the two is critical if you want to take advantage of a smart outlet. Aug 21, 2019 - Includes all necessary hardware to easily mount the unit onto a cabinet and power it through a standard wall outlet. They run a couple bucks. AC Rated Output: AC 100-240V, 50/60Hz, 1250W. Cooling fan Includes a 12038 aluminum fan with 110v/125v power plug cord, two 120mm fan guards, and two sets of mounting screw set Computer fan designed for projects that requires cooling or ventilation; or as a replacement fan for various products. This is a technical ELECTRONIC ENGINEERING subreddit, covering practical, component-level circuit design and repair questions, electronics theory, electronic components, tools and equipment. This will ensure that the top node is always positive and the bottom node is always negative. On these 4 wire computer fans i have found that some times they require an input to tell it how fast to spin so simply supplying power to 2 of the wires will not work if you have a 3 wire fan however you can supply power to the red and black and leave the white disconnected. But you can. We carry all different sizes of pc … Here you can see the broken-off prong stuck in an outlet in the lower right. Your fan should now be working! Computer case fans. If your circuit is correct, you should now be able to probe the top and bottom of your full wave rectifier in and see around 12VDC. A 4-wire fan has power, ground, a tach output, and a PWM-drive input. If you add a capacitor please alsow add a diode to protect the capacitor from the negative inductive voltage, Reply I suggested she use a computer fan mounted on the outside of one of the vent holes (size yet to be reported.) You can most likely get one from a flee market for a buck. They're screw terminals so she won't need to solder anything. Strip these back and then solder the wires onto the two primary connections on the transformer. Find low everyday prices and buy online for delivery or in-store pick-up I was able to find 4 in an old battery charger that I don't have any use for anymore. What type of power comes from an outlet? This enabled me to separate the light and the fan for light dimming and fan speed control. I modified a regular computer fan to work as an electricity generator.

If she doesn't go the USB fan route, I'm sure she can manage this. fabfun New Member. Just attach the wires from your fan to the power supply and keep the colors matching. Look on the bottom to see the polarity. If you have a large aftermarket CPU cooler, it probably has one or more fans of its own. For three wire fans, you don't have to connect the yellow wire (it's the tachometer signal which you can read to find the fan speed) Just connect all the red wires to the + and all black wires to the - of the AC adapter. Step 2. These will restrict the current flow and create DC power from the AC power in your wall outlet. Velocity is given by: radius or length of fan blade in meter from the center and multiply it with fan rpm. The wires will remain connected to the fan. If it has red and black, simply repeat what you did with the fan but use the Power terminals. 5 years ago The higher this number, the faster the fan will spin. First find velocity of fan blade. Verify that the AC adapter is not damaged and is connected correctly to a working wall outlet. Im afraid to put the AC in the same outlet because the AC uses a lot of power and when I have a vacuum and an AC on the same outlet it trips the circuit breaker. And how many amps?
