I just have 12V DC, this is not going in a computer, what is the third wire for ? Will it be clear how to connect it to run full speed ?

Generally the first 2 wires in a 3 wire fan plug are the DC hot and ground, the 3rd wire is used to read the rpm of the fan by most newer mother boards.If you are replacing the unit in a PC that has some sort of temp control that varies the fan speed it will take care of the speed control automatically. Otherwise it should be full power all the time in systems without fan speed control.

yellow wire is for a connection to something that can control the fans RPM. should run at full speed without it.

Many computer fans have three wires - +12V, ground, and tachometer. Here is more detailed information:www dot pcbheaven dot com/wikipages/How_PC_Fans_Work/You should have no problems.

I bought mine for running a Humminbird depth finder in the house. It will power anything needing 12 DC as long as it is less than 3 amps.

I also bought this . It only works on a 24 volt dc system. Mine was not advertised to convert from a 12 volt dc source.

It is 12VDC.Something isn't right, don't use it until you verify what is wrong or you may damage your battery or charger.You may want to double check you meter settings. (12 volt DC. etc.) You might have to return it or call the company.I use mine on a deer feeder and it has worked great!

Hello Ashura,Because it's a 12V product,so you need a power supply,Please input AC120V to it and than connect the product to the output of the power supply.Thanks!

This is a computer fan - not a fan that you would use for, say, cooling a room, so you wouldn't be hooking it up to a standard 120V A/C plug. You would need to hook this to an A/C to D/C converter of some kind (like a computer power supply) that provides between 5V to 13V D/C output.

Just wanted you to know that the wiring on this thing is backward, at least as far as the DC part is concerned. I don't use the AC part. In other words, it only works when you hook your DC input (battery) to the output side, and your output to the side marked "battery." The printed instructions that came with this item is wrong. If you hook it up according to the manual, it will not work.

you need 12 amps from an additional 12vdc power supply. you are taking the signal from an led controller and adding power down the line

Contact the seller, they are very very helpful, and purchase the 12V splitters for your needs. Just be sure that youdon't exceed the capicity for the power supply.

Doesn't matter how you wire them since the driver circuitry has an inverter bridge. They can run on 12V AC or DC. I believe the wires are black and red so following convention I wired black to negative and red to positive.

Out of the box it is only 12 volt DC. You need to purchase an adapter to connect to 120 volt AC.

The 2 wires are for the monitor voltage and also power the unit. I only tried it at 12V but my guess is their voltage regulator can take the full range of voltage and convert to 5V or 3.3V

The end of the wires are a bare connection. You would use a connector to wire it to a 12V fuse protected circuit.

This fan is 12 v dc, You have to use a 12v dc power supply 2-3 amp. They sell for about $8-$10. Solder leads to fan and plug in wall.

It needs 12VDC, center-positive. The spec sheet says it draws 7W, so get a 1A wall-wart and you should be A-OK.

I'm afraid I don't understand your question. I used this as a cooling fan for a ham radio by simply connecting it to a 12VDC power source.

I called their number looking up on internet and they were very friendly. They would tell you quickly. They did inform me it will not function with less than seven amps from your dc. I found a loose wire attachment in fuse area and the new one I updated(they suggest replacing every five years). Once I fixed they intermittent three amp reading by tightening even the old one worked again, but safety trumps cost.
