airflow + help with decission

[Jord1990]

So it is almost time for me to order my pc, but some last minute doubts showed up.

I really like the looks of the corsair 760t and the 780t, however I can't decide which one I want.

I Will probably go for sli 980s, but im starting with a single one. so space is not really a problem.

Another thing I also wanted to ask is that I'm planning on getting h110I gtx with it. Which if you were to mount it to the top would mean you have 2 intake and 3 exhaust fans, which is not ideal right ?

Yeah it's recommended to have slightly more intake then exhaust, at worst equal amounts. Negative air pressure accumulates more dust.

Try it out and see how it goes. It is  easy enough to remove the rear exhaust fan. It is just as easy to add a 120mm as intake on the bottom.

Any advice on which of the 2 cases ?

So if I go for the 780t I can put 2 sp120 in the bottom. Which would make it 4 vs 3 with intake vs exhaust. Is that an idea or just plain overkill. The 980 will have open air coolers so I don't how much airflow is to much.

I wouldn't worry so much about air flow. Any objective studies I have seen suggest very little cooling difference between higher exhaust or intake schemes. My usual suggestion is go with stock. Use the motherboard utilities and other software to monitor temperatures. If needed, play around with the fan configuration. This will let you know if you need to add a fan or two. They are reasonably inexpensive and very easy to buy and install after the fact.
