How many fans are in a box?

Just one but you dont know what color you will get, its a random pick. Also these are usb ends only, you have to buy an adaptor to plug in a wall outlet or plug it into a computer to power it. They work good, but a little loud...

One, and you don't get to choose the color. I got a black and a red one. Love them.

As far as I can tell all six fans are there. I haven't had any overheating problems.

I'm not sure if you are asking about 8 paddle fans or one fan with 8 paddles. In either case, the answer is that you are not providing enough information. Switches are sized according to the MOTOR they are controlling.

Supports up to 6 fans. Two come standard and provide adequate cooling. See http://us.coolermaster.com/product/Detail/case/mid-tower/haf-912.html. Specifically two in lower front (one optional) , one in lower side (optional). These are intake. One upper rear and two top (optional) exhaust. I am running a 1T fixed and a 500 gb removable drive, 8 gb memory and an i5 processor on just the two fans that came with it, no problem. I blocked off the two upper grates to preclude grandchildren inserting "things".

I would actually use 2 fans. One to push and one to pull. I used these for a Dish Network receiver which runs very hot inside the cabinet. I used one fan to blow air into the box and one fan to pull air out of cabinet. Works great.

This has 1 fan. But the GTX 770 by Gigabyte has 3 fans on it. It's a little bit more expensive but totally worth it. It looks amazing.

Three 120mm fans can be installed. Two in the front & one in the back. It comes with one "True Quiet" fan mounted on the back of the case. I added one fan to the front of mine. Very quiet.

It comes with four fans; two on the hard driver holders; one large fan on the top of the case (blowing out) and one exhaust fan on the back on the case, also blowing out. There are spots for about four more fans; two on the side of the case and I think two on the bottom. The bottom two are very difficult to install because wires and your power supply make it pretty tight down there. The side fans, however, are very easy to install and I recommend you get those. Just two regular sized fans (not the giant ones) will fit there easily.

I only had 1 in the box it was about 3" long. I believe that is typically what you get with a fan.

Yes I don't think two fans will be needed however. They put out a great amount of air and also pressure.

There are 3 fans one in the front one in the back and one on top. I didn't hook up the top one. With just the front and rear one on in order to hear it I have to put my ear up to the box.

The case has room for 3 fans. 1 on top, 1 in rear and one in lower front. The top and rear are the new larger fans. Beware that the top mounted fan will add noise under a desk. The one large fan in the rear keeps my setup (i5, 6 drives, 12 GB ram) cool. I use it as a server not a gaming box. The power switch is hard to see but it is there along with a reset button. They are hard to find unless looking directly at the case. (not an issue). The case does have a couple of usb ports built in. I used an MSI board and added additional usb and multi card reader. It is a great fan for the money. Don't think twice. Buy it! The case has room for 3 fans. 1 on top, 1 in rear and one in lower front. The top and rear are the new larger fans.

It is only one fan. the 20PK is part of the identification number for the product by the manufacturer.

Mine has two small cooling fans. About the size of fans you see in a computer. Seems to do the job.

I have seen multiple configurations (SKUs) of this case over the past several years that offer various numbers and types of fans. Its confusing, and kind of silly, but its true. So the best answer I can think of is to advise potential buyers to ask the seller directly about which SKU they are selling, and how many fans, what size fans, and if the fans are lighted, what color, etc.

Agree with Pbear's response. Love the fans -- I have installed three of them.
