What size fans will I need to buy?

Merry Christmas! You can put two 120 or 140 fans on top and the same on the side. You must be forewarned, if you put two fans on top you won't be able to put optical drive in the top 5.25 slot. It hits the fan and sticks out too much. I put two fans on the top and put the optic drive in the second slot. When we have a need for usb 3 ports I will get either a 4 port usb or a card reader with two ports which will fit in the top slot. If you must use the top slot I would suggest a 140mm in the back of the top and if you have a hot graphics card, maybe two 120mm 's on the side.

I would also recommend the larger fan. I installed the 110cfm fan in our 10 x 12 bath and if works great.

Yes, you can add two 120mm fans to the side panel. EDIT: Actually you can probably add any size but 120mm would makes the most sense.

Dude, That's a representation of the size differences. One fan should be listed. lol

That 400 fan would work Perfert. That's what I have for about same size room. I hooked up a fan speed controller. That hydro fan is awesome!

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.

Yup, it should work fine. So long as it is the same size, should be 120mm. Might double check though. If you check out the picture, you can put any fan on there so long as it's the same size. It just holds on with the little metal brackets.

Don't think you can use fan other than original size. Furthermore, this is really a very quiet fan.

It's about 260mm wide by 305mm high. Either size fan should fit pretty easily.

Hi Kyle, If your motherboard is ATX, then yes. The fans are all 120mm except for the front, which is 240mm. As for the expantion cards, I guess so as I dont own what you have. But I have a graphics card and it works well length wise. So you should be fine. If you not happy you can always return the case. :)

Honestly any 6 inch inline fan will move more than enough air. A 4 inch would probably do fine but i like my 6". As far as a brand i dont have a preference i would let the reviews do the talking.

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

I need sizes on your video cards. There is more than enough air flow to keep it cool....2 fans in front, 1 large fan on the side, 1 fan on top and one on back!

I comes with one 120mm in the rear and has a 120mm port in the front and has two 90 or 92mm door fan spots. I haven't needed to use them. In the past, I have put fans on the inside just to push on my graphics card. So you could put 4 or 5 fans on it but it would be overkill for my system. Does that answer your question?

it depends on the fan's mounting space if it can accomodate the 140mm size of course you can mount them. moat cases offer 120mm and 140mm mounting holes these days i think it would fit on a case to caae basis

Be careful with the power requirements for your Graphics Card. Many 1GB+ Graphic Cards need 400 watts or more. Also, you need low-profile cards. Standard are too tall. For the CPU, a standard fan that comes with a CPU should be fine. I have only used standard in them and no issues. You only get about 3.5 inches of height for that fan. You may want to confirm the measurements of your CPU fan against the width of this case (3.9 inches is listed in the seller's description).
