If only the red and black wires are connected which speed do I get on the fan?4500 or 3700 RPM? What does the yellow wire do?

With only the red and black wire attached, the fan will run at full speed. The yellow wire is the speed detect.

Nothing. Just pull the chain. Each consecutive pull changes speeds. It's a great fan.

1 speed. These are nice little fans. I bought 1 for my Mom to help her sleep better, ended up buying 2 more for us.

It has a really powerful fan. It has a 440 speed. Fastest they sell for these. It's been a while since I purchased this. I use a speed controller on mine because my area doesn't need to use it on highest setting. I use it just above the medium setting. Being able to dial in power level is important. Too strong and it won't scrub air correctly. I use it as a stand alone. Not connected to lights. Also occasionally change the charcoal. After months of continual use. Good luck buying your air scrubber. Kaptain Kindbud

1080 RPM to 1320 RPM (+/- 10%), and they use a standard 3 pin Motherboard fan connector. I just don't understand why people are fixated on fan RPM though, when it's the CFM that really matters... (which is 44.73 CFM on this fan if'ya care). Hope this helps

Indeed it does, as soon as the temperature hits 40 the fan is moving near 150rpm. If the load is sustained or increases the RPM jumps accordingly. Its got a 140mm double ball bearing fan so it doesn't need to move very fast at all to push a lot of air. I use eco mode and have all of my fans running on a NZXT SENTRY 2 controller on automatic with temp sensors at all major components, it's dead silent for such a large rig and fans on every surface (including a 300mm blow hole).

CFM is the best on the market. The problem is that the speed control is LOW quality. You will need to cut off the speed control, and add a cig. lighter plug with fuse. I had 3 fans-speed control broke on ALL of them in just a few months!

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.

n.darwin is correct. The fan has a rotating speed switch that has three speeds on each side of the rotating switch and two off positions that can be turned by hand or by a pull cord .

The wiring is straight forward , the red wire is the power source going in , that would be the black hot wire in the USA next to the red is the black wire where you connect the white neutral from the power source. Then the other black wire is where you connect the neutral white wire to the load ( lights or fan) , next is the yellow wire you connect the black wire to the load again lights or fan.

This is a 12V. Fan, you cold apply 12v. directly (Ground and +12V.) and it will work at it's maximum speed (google "pc fan connector" to find out) The connector is: |Ground - +12v - Speed sensor - Speed control| However this is intended as a computer fan, i will not recommended it for any other use.

This motor is could be 7.5% faster than you old one. But 1000 RPM is a very odd and rare speed, most likely your old motor has the same number of windings as this one and is really moving at 1075 RPM, but the label says 1000. Common ratings for these fan motors are 1050, 1075 and 1100 RPM. I wouldn't worry too much about it, but I do recommend replacing the start capacitor with a new one (that is rated for this motor 5mfd/370V Capacitor) when replacing the motor.

Forgot to mention, the case fan is quite loud so I would either replace it with a quiet one or get a simple fan speed controller. This is what i got.

No, the fan needs to have two speed capability. There would be three / four wires.

The unit is nothing more than a thermostatically controlled relay. The wires hanging off the unit are connected to contact points inside. Just make sure that your fan current pull, does not exceed the current rating of the EL4V's contact points. I assume this is a single speed fan.

don't know the rpm, can't hear it running at all. I bought the 430watt about 5 yrs ago and its still going, I currently own 2 more 600watt's, would recommend this psu. hope that helps. hint if you're used to hearing a noise from your computer you might be hearing the cpu fan, especially if it is aftermarket.
