Is this variable speed or just 1 speed? I only see 3 pin connector.

Does not come with an adapter that can allow it to be controlled by the motherboard. These are one speed fans that come with a 3 pin to 4 pin MOLEX adapter so you can hook them up to your power supply or maybe a fan controller. These are not PWM fans. I bought them once thinking they were and returned them. These are the fans you want if you want PWM. Andrew is wrong.Cougar Vortex PWM 120 Cooling CF-V12HP, Orange

Comes with adapter to be controlled by motherboard to achieve low RPM.. or just use a controller for speeds like 800 to 1500 RPM

The one I received is a three wire. I don't remember what my response was to this mechandise. I do remember the one I ordered pictured a connector, and the one I received had no connector. The seller compinsated me for that differance.

3 connections? It had 1 plug in...not sure how many wires were in it. What kind of vehicle is this for?

It is variable speed. I don't know how I would measure whether it goes to or beyond the specified speeds.

I bought this about 6 mouths ago and do not recall the number of pins. It seemed to have all that I needed to make it work. I asked the person that bought it for me and he thought it had 2 6 pin connectors.

i think so. it has both connections to choose from.i used the three pin one.

No I believe it is 1 speed only- power switch is on/off only- no speed options that I am aware of or ever used. There may be a fixed metering device to slow down flow for hot tub or other applications but I have not used this in that situation.

To be absolutely concise - the fan has one 3-wire connector and one 1-wire connector. The 3-wire connector works on a non PWM 3-wire motherboard connector. IN this case the 4th wire/connector is not used.If the motherboard connector is 4-wire then you first plug in the 3-wire connector from the fan and then plug the 1-wire connector into a slot in the 3-sire connector. Doing this results in a 4-wire connector which then supports PWM speed control.

It is a four speed, but it can be used on any speed. I have mine hooked up to an original three speed fan and it turned it into four speed.

It is 1GB port switch. I have 3 Desktop connected to this switch and all shows link speed 1.0G with full duplex. This switch is connected to 1Gb main access switch in server room.

One fan. Furthermore, any PWM splitter is only going to be seen by your motherboard as one fan as only one of the connectors will be wired with an RPM wire, while all will have GND, +V, and the sense wire to control fan speeds. Any non-PWM(voltage controlled) splitter will only contain RPM on one fan and GND/+V. If you want to see individual fan speeds you will need to use individual ports on your motherboard or fan controller.

I am not sure why you are asking for 2 or 3 it has only one connector, that's what you need

I have mine hooked to 4 pin. But I believe the specs said it will do both. Google it and specs will tell tell you.

I can't remember exactly because I repaired the computer for someone else and I don't have the old parts to check. I think it is 12 pins.

That would depend on the motherboard I think. It uses a 3 pin connection, but only two wires. The voltage would have to vary in order for the speed to vary. I'm not familiar with how those controls work, so I can't say for certain.

Mine is a 371 and is not variable speed. If I remember correctly when I bought mine there was another model that was variable speed. Maybe it was the 371K. Anyway the thing gets hot with continued use. "Continued" meaning 3 minutes or so. Good luck!

1/2 HP contiuously variable speed. 110 volt ac input. I don't know what happens inside.
