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".

-If you use 120mm only, 6 fans will fit.-If you use 200mm only, it will fit 2, but the only the cooler master brand may work for sure. I do not recommend getting 200mm for the top because eventually it makes clicking noises as it is not designed for that orientation. For reference, mine makes a clicking noise.-2 140mm fans would also fit at the top.-The fan slot locations are: 1 back, 1 side, 2 top (or 1 200mm), 2 front (or 1 200mm)For future reference, a quick google search on this would have produced the answer you are looking for in even better explanation. Just a friendly reminder. -If you use 120mm only, 6 fans will fit.-If you use 200mm only, it will fit 2, but the only the cooler master brand may work for sure.

Yes. There were 3 fans already installed in the case. One in the back top (small), one in the front bottom (large) and another on the top (large). The one on top actually has room for another one beside it, but with those three plus my cpu fan I didn't bother.

3 total. It comes with a 120mm in front, has a 92mm slot in back, and a 120mm on the side panel. I've seen pice of people who've modded two fans onto the front but I don't know the details. Enjoy!

3 fans that I can see. I've left it on all day & night and no overheating issues. The case is very breathable. Only issue I've had so far is it restarting randomly with a blue screen. Apparently it's driver issues and not the computer itself.

only 1,but can install 3 given the right circumstances, most use 2 without issue though, all 3 are the larger size fans as well {120mm fan}

This case allows for 2 fans on top,1 in the front, and one on the bottom. A total of 5 fans can be put in the case. The case is supplied with only 1 fan in the rear, all slots used would total 5 fans.

Two front 120mm, two bottom 120mm, one 120mm or 140mm in the back, and one 200mm or two 140mm or 120mm on the top. In total with the default, there would be 4 fans and you can add two bottom ones and making it 6 fans or remove the 200mm on the top and replace it with two smaller fans for 7 total. I have the trooper and have a total of 7 so far but can add one more because of the side panel isn't windowed

It comes with 2x120mm fans on top and 1x120mm fan on the back, and can take 2x120mm fans in the front of the case ahead of the drive bays, and 2x120mm fans in front behind the drive bays. Grand total of 7 fans supported, 3 in shipping configuration. Source is the user manual.

I installed 4 120mm fans, one on the bottom just in front of the power supply, one in front behind the front cover of the case (that just pulls off) one in back of the case and one on top of the case. If you have a mid to full size mobo, the top fan will have to be moved over a bit and then secured with just 2 case fan screws as it will not line up properly, mid to full size mobos tend to block the fan from being installed on the pre fit holes.

Yes you can put a 2 fans in the top if your motherboard allows for it. My RAM almost touches one of the fans and the other fan spot is blocked by my CPU heatsink. There is also a spot for a fan in the back that blows directly on to the CPU. As far as the front goes, I'm almost positive you can put one behind the front panel but I've never tried to do that.

Yes...one cable supports 2 fans. So you can have up to 4 fans for your 2 plugs. Keep in mind they run in parallel and are treated as one fan on MOBO.

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 pin fans, but they will work with four pin connections. I use mine with and four pin MSI motherboard.

In short, yes. I have four fans connected to one motherboard fan header-- one fan connector to the mother board, and from its two "outlets", two more connectors, each to two fans. CAUTION: Look up the motherboard specifications for Amps supplied by one fan header, and then find how many Amps each fan uses, so that the total is not more than what the motherboard header is rated for.

"Plug in (a quantity of) 4 USB fans?" Why would I do that? No, just one fan. Perhaps I misunderstand the question or you're implying someone's an idiot.
