Question 1

How do you control/switch the speed?

Accepted Answer

you put the short extention on the end of the plug and you have to have a board that can control the speed or buy a speed controller. it must be put on a 3/4 pin plug designed to work this way. I have an asus x79 delux motherboard socket lga 2011. I know that the Sabertooth works this way too.

Question 2

what is the voltage on this fan?

Accepted Answer

It can be plugged into the fan header on your motherboard. 
Or the fan headers on you fan control hardware if you are going that route.
I believe MB headers run at 12v.
Fan is quiet and responds to speed controls.
Good price also.
Not fond of the orange highlights, but my case is windowless so it is not an issue really.

Question 3

will i be able to mount these horizontally and will i be able to control these from a fan controller?

Accepted Answer

You can mount the fans anywhere/way you like.  They come with rubberized mounting pins.  Most fans can be controlled as the power from the motherboard is typically Analog PMW (Pulse Width Modulation) .  So if you're using a controller, this shouldn't be a problem.  I have one of these across 4 drives in my linux box and I wrote a script to send values to the hwmon devices (pwm1..pwm4) to silence the cans using the ports off the motherboard.

Question 4

does this have a molex plug? i don't have any currently availible 3-4 pins on my mobo right now

Accepted Answer

just got this email - i can't remember if the box had them. ill have to check when i get home. i still have the original box and everything they came with.

Question 5

Are these able to be mounted on the top of a Corsair 500r? (I would need possibly two of them) Thanks

Accepted Answer

I have one on top of my case. It works great and looks cool. I got a grill for protection from the blades. I have it just sitting there with the silicone 'screws' holding it in place. With the resistor adapter, it is practically silent even sitting on top.

Question 6

Does this fan work with PWM so the motherboard can automatically adjust the fan speed?  Is that what the 3 to 4 pin adapter is for?

Accepted Answer

No.  
The manufacturer states that PWM creates noise in fans (it quickly turns them off and on to lower speed).
The adapter is so the fan can be powered by a 4 wire port.

Question 7

is there a way to adapt this to a standard  American 110 v ac plug?

Accepted Answer

Not easily. This is a 12v DC fan. You may be able to power it with a 12v DC power cube.

Question 8

When installing horizontally (exhaust), did you use the metal screws or the rubber pins?

Accepted Answer

Rubber, anything to reduce vibration. personal preference.

Question 9

I feel dumb for asking this, but how in the world do I install these things into my case?

Accepted Answer

Google your case's fan placements (ex. "NZXT H440 120mm fan placement"). In the H440's case, there are 3 120mm fans at the front, 3 120mm at the top, and a 140mm at the exhaust in the back. Be sure to have your rear exhaust fan pushing the air out of the case (inlet side is facing inside the case) and the front/top fan slots are pulling air into the case (inlet side is facing outside the case). There should be clear screw holes for you to install the fan into. The cable that's attached to the fan will be plugged into the fan connectors on the motherboard. Be sure your motherboard is powered down when you do this (shut your PSU off). Have a great day!

Question 10

So if you use the 3 to 4 pin extension and plug it in to a fan controller will you be able to adjust to speeds anywhere between 700 rpm and 1200 rpm or is it just gonna be only those two speeds to choose from?

Accepted Answer

I believe the adapter has a resistor in it which is why it only reaches 700 rpm. Otherwise you should be able to adjust it all the way up to 1200 rpm.
