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".

It depends on your setup, stock you can add 3, two on the side panel and one on the bottom. I use a water cooled system so I use the rear 140 mm and turned the two led 120's to draw from the front. I have the H100i mounted in the top so up there I have two 120mm fans. The case is huge so you should have no problem keeping it cool with the stock setup.

I have the PC behind my monitor. I honestly can't tell you if we have 2 or 3. Anyone out there in Amazon land have quick access to the cover to count the fans? Sorry. So far no problems and cpu runs cool. I do take all precautions to always keep items away from top and side airvents.

Comes with 4 fans (3x200mm, 1x40mm)From what I've counted you can install another 200mm in the top, and 120mm in the vga Duct, and an 80mm in the vga bracket. However you can install a lot more if you were to do a tad bit of jury rigging. (I'm doing this and I've found a way to install at least 5 more 120mm)

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.

It has 3 fans one in back one on top and one in front. There may be enough room to fit one more 120 mm fan if you want

No, there are not. I installed two mini 40mm fans though by drilling my own holes. If I could do it over again I would go with 45mm fans, 50mm in a little too big, I measured. You will have a very difficult time getting any fans in there without swapping the power supply with a pico-psu.

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}

Yes you can add two fans on the left side panel, but I don't recommend doing so because adding two fans on the side will obstruct the airflow.

They lined up with all the holes in all locations on my computer. I put in 4 of them. It has been long enough now that I don't remember the size of the fans I replaced.

This case has room for one 80km 90mm or 120mm exhaust fan in the back of the case and you can also connecct a fan to the side vent, up to 120mm. So two 120mm fans total should be all.

I believe it came with 3 but uses 4. I bought some other led fans to use in it, so there was a couple of the ones that came with it that I didn't use. This case is awesome plenty of space inside lot's of fans to keep it running cool, and it is built very well and looks awesome :)
