It does not have fan slots. It does contain a fan for the hard drive bay and the big fan over the board. It's open frame design lends itself to not needing more

You can mount 6 fans; the case comes standard with one in front and one in back, both of which are replaceable. There are settings to mount fans on on the top (2) and on the bottom (1) By removing a set of drive bays(middle, as you would remove for a large video card), you can mount another fan in front.Short: 6; 1 rear, 2 front, 2 top, 1 bottom

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.

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.

3 200mm fans are included with the case (front, side, top). 6 is the maximum amount if you remove the top 200mm to change out for 2 120mm.

It has 3. The gaps are wide enough a kid could easily stick their finger in the fan. I can fit my pinky through easily at the front of the fan, but not at the sides.

There are 2 connectors. You should really get a fan controller or something of the sort. Two fans won't cut it. I have 10 in mine but that is all personal preference.

There are 2 system fan slots. One is a 4 pin and the other is a 3 pin. There is also a 4 pin CPU fan slot and a 3 pin Power fan slot so 4 total on MB. Hope this helps you!

The entire card takes up two slots, the fan takes up only one of them and when installed sits under the ports. It's a great card, I have two configured in Crossfire.

This comes with two fans. It has eliminated overheating on my old Dell laptop.

Just for future reference when others want the info, here's the mfr. website specifications link. In the cooling section it states all fan slots are capable of 120mm & 140mm. http://www.fractal-design.com/home/product/cases/define-series/define-r4-black-pearl

It has a CPU main Fan connection as well as a CPU "Optional" fan connection. Then there is 1 Chassis fan connection on the right side of the mother board and 2 more chassis fan connections on the left side. That is 2 CPU Fans and 3 Chassis fans, which brings a total of 5 fans that can be connected to this MB.
