I see at the back of the case over where the MOB sits, the frame is open and has pre drilled holes, can I put fans in there,what size and how many?

The back of the case is open, but I don't see how you would mount fans there. The top of the case swings back, which makes me think mounting anything in that open area would be difficult. There are several open card bays on mine, and I think I have the biggest MB made. You could definitely mount a fan card or two there. I'm running a pretty tweaked system and haven't had any overheating issues.

Yes you can. Its meant to hold radiators for AOI or custom loops but can put just fans for extra flow. It hold two 120mm or two 140mm fans (so any rad from 120mm to 280mm will fit). Also my h100i ( a 240mm rad) only one of my 120mm fans lined up perfectly so the rad was held only by two bottom screws on one fan but was never a problem and had no vibrations even when fans were at 2400rpm.

There are a few pre drilled holes to mount a radiator. I wouldn't count on them lining up perfectly. Be prepared to pre drill your own holes. Just a heads up. Will fit a 120 rad

hello. you can put 6 fans in. there are 2 x 120 mm fans at the front end. 1 x 140mm fan exiting the rear. & you can add 3 more 120mms to exhaust out the top. however you will lose the space for the DVD drive at the top front if you use the 3rd fan bay at the top.

You can fit five fans the most. It depends on how big is your fan. A min of 4 can be installed.

There are two 80mm fan mounts for the bottom half of the case. They are intended to exhaust air, but you could turn the fans around and draw air in. The fans would point straight at one of the drive bays.

yes your case has spots for 3 120mm fans which is what this is. they are great fans and very quiet.

I don't see why not as long as you have mounting space. We added it in a fairly small hp case, and we mounted it to the side of the case over the perforated vents. Yes, we had to drill 4 holes, but in the end the fan is working to provide some extra cooling.

Per the tech specs you can mount on the side either 1 200mm fan or 2 120/140mm fans. http://www.corsair.com/en-us/obsidian-series-550d-mid-tower-quiet-case

There are two slots for top fans. They can hold two of either 120mm or 140mm fans

Technically 2. It comes with 4 fans already (1 on the top, 1 on the rear, and 2 on the front with support for 2 more on the bottom). You can also remove the top 200mm fan and replace it with 2 120/140mm fans, thus giving you a maximum total of 7 fans.

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 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.

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!

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.

There are prongs on the fans that latch into the holes in the stand. Select placement and release the fan prongs to seat the fans.

Yes it is possible, I personally left the stock one and just added two extra one where the case does not provide. It is just up to you. If you have the extra money to buy three fans . Go for it !

2 on the front, 2 on the top, 1 on the back, a huge 1 on the side. You might be able to fit 1 on the bottom too. So that is 6-7 overall fans.

It comes with 3 fans. One in the front(Blue led fan) then one in the top and one in the back. There are extra spots to put 2 more fans on the side of the case, but really the 3 work just fine.
