Need help optimizing airflow on a CM HAF 912 Combat case

Hello everyone,
I am fairly new to building a system. I have done a lot of reading and so far I ended up with this list of items to buy:

Dilemas:
1. What kind of fans come stock with that case?
2. Considering the 2 fans from the GPU and the one from the heatsink, how many other fans and what types I need to buy to have a proper airflow / cooling?
3. How should I place em in the case?
4. Any other suggestions you might have about this build? It's for gaming. I haven't yet decided on the RAM, so some suggestions here could help. I usually play games like wow, civ5 and would like to build a budget rig to handle max settings or so on these kind of games.

I will use my old hdd and other components until I get more cash. Thank you in advance for the help.

Case: CM HAF 912 Combat
GPU: 1x MSI GeForce gtx 680 Lightning Unlocked (This item is already bought)
Board: MSI Z87-GD65
CPU i5-4670K
CPU Heatsink: CM Hyper 212 EVO
PSU: Corsair Enthusiast Series TX750M V2 750W

the case already came with 4 fans http://www.coolermaster.com/case/mid-tower/haf-912-comb... so you could start with this and you could make change for the fans after if you need and check the picture on the link they show you how .


I have been watching a bunch of unboxing vidoes after my original post and I only see 2 fans. 1x120 in the front and the one in the back.

Can use the ones that come with it and add another 120mm each to top and front, or pull either the top or front and use a 200mm fans in those areas, (I added a 120 to the front on mine and put a 200 up top (rig itself, the Haswell is in sig)


Ok, so how many fans you have now? You have 2x 120mm Front? 1x 200mm Top, nothing on the Side? and the one in the back? You have 4 fans in total?

From what I have seen in some unboxing vidoes, the case comes with only 2 fans: 1x120 Front and another one in the back.

Didn't put that too well, it comes with a front and a rear 120, your options are for a pair of 120s in front total or a 200, same with the top, and can put a 120 on the side panel, so while you have 2 w/ the case it can use up to 6 120 fans, I pulled the stock fans and used red led fans all around, a 200 on top, 2 120s in front, 1 in back and 1 on side

Ya, I am going to buy 2x 200mm CM Megaflows = 1 for front and 1 for top. The one that comes stock in front I will mount it on the side.

P.S- I might end up overclocking my rig. Do you guys think the Corsair TX750M and the Hyper 212 Evo will be handling OC? As for fans I will fave:
1x 200mm Front Intake
1x 200mm TOP Exhaust
1x120mm Side (intake)
1x 120mm Rear exhaust
1x Cpu cooler (212)
+ the PSU and the GPU ones

Would that be enough or I should maybe go for 2x 120mm instead of the 1x 200?

That's basically what I have (exception 2 120s in front and keeps things nice and cool, my 4770K is at 4.6, full load of DRAM (not really much there heatwise, but also have a pair of 780's in SLI OCed to 1120 or so, so when CPU is idling at at 32 or so and mobo temps down low,, I'm quite pleased

check the front one if you put 2 fans one will be at the bottom and the ohter at the middle case and bring fresh air up to the top so i would try with 2 120 mm in front as intake the side could be optionnal and you could use a 120 mm or 1 140mm the top a1 200mm as outake and 1 120 mm for the back outake .you will have a good air flow for the overcloking .
