Question 1

Hi! I know nothing about fans at all. So please answer these simple questions: 
Where do I put them?
How many do I buy?

Here are my specs:
Intel Core i7-4790
GeForce GTX 950

Will it work with this motherboard:

ASRock H97M Anniversary LGA 1150 Intel H97 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard

Thanks!

Hello,

These are case fans, I don't know what case you have so can't comment on how many or where. The cases manufacturers web site or the owners manual will tell you what fits and where.  So if the case has 120mm fan mount locations they will work.

Generally speaking case fans move are from the front or lower portion of the case to the rear and top. If you have both intake and exhaust fans you will want to be sure that the fans pushing air into the case have more airflow (CFM) total than the fans exhausting the air. You will be able to drive them either from the motherboard or from a fan connector off one of your power cables.

As you have a micro MB I assume you are building into a small case. In my HTPC mini case there are 4 fan openings, 2 120's; One at the front and one on the side. There are 2 80 mm exhaust fans on the rear. As small fans tend to be loud to move a lot of air I got the quietest I could and throttled them down. The 120's run with a speed reducer as well.

Question 2

Is this good for use as a CPU Cooler on a Cooler Master Hyper 212 Evo?

Accepted Answer

My noctua cpu cooler uses two fans like this so I imagine so. Just compare the CFM between the two fans.

Question 3

would these fans do good in a case with led strips?

Accepted Answer

I have Fractal cases so this fan matched what was already there.  The fan does not have any lighting or a connection for lighting.  It's a standard size.  The fan blades are white and reflect light well. If the Led lights  do not flash they would appear as a soft white disk.  If the LEDs do rapidly flash there would be a strobe effect making the fan appear to turn at a different rate that they actually do.  If that's good or not is an arbitrary judgment call you'll need to make for yourself.

Question 4

Can this fan be attached to a Cooler Master Hyper 212 CPU cooler?

Accepted Answer

Physically - due to the mounting hole locations - yes it can be attached. Both are/have 120mm fans.

Functionally though, I believe this fan lacks the PWM controls to be controlled by the CM Hyper 212. I own these fans and the Cooler Master GeminII M4 - I changed all case fans within my Fractal Design case to a combination of these 120mms and the 140mms except for the fan that came with the CM GeminII, and I believe the reasoning was that the Fractal fans weren't PWM. I did this build back in early 2013 though, so hopefully my memory is correct. Just make sure to verify this PWM variable between your CPU cooler and the fans you select, otherwise you'll end up with a fan on your CPU cooler that runs at a constant rate rather than spinning up and down as required by your CPU loads.

Question 5

I am using in a non computer application. How exactly is the 3-pin connector "driven"? Does it need DC, or a special driver?

Accepted Answer

This plugs into a computer motherboard adapter.  It is a DC voltage fan.  I believe the voltage is 5 to 12 volts.  You should have no problem hooking it up to a 9 volt battery to run it.  I believe the only two wires you will need is the red and the ground.  The yellow is just to communicate with the computer motherboard so your computer knows how fast it is spinning.

Question 6

I have a corsair carbide series spec 01 red. any idea why this won't fit in the back of the case above the PSU? are these only meant for fractal cases?

Accepted Answer

No idea; but you don't say what prevents it fitting. Looking at the case here (not in person), it appears there is plenty of room up there.  So, tell us what is interfering.  Holes don't line up? Hitting another fan?  I happen to use Fractal Design cases, but the Corsair looks nice and I don't see any reason it shouldn't work.  Tell us more!

Question 7

How much wattage do these require?

Accepted Answer

It you have a large power supple  with a good MO when I don't see what the wattage matters
