Two 140 top fans, intake or exhaust?

So, I've got a 650D case. So it's got a 200mm intake at the front and a 120mm exhaust at the back. I've got a H110 mounted to the top with the fans in a push, intake configuration at the moment. But I'm unsure if this is the correct setup. Should I have them in a pull/exhaust configuration or a push/pull exhaust config (Can't do Push/exhaust and I'm unsure if the 650D has the space for a push/pull).

Thanks.

 

EDIT: Forgot to mention that I've got a GTX 780 with a EVGA ACX cooler on that is exhausting some air out the back.

I would say exhaust.. But then you will have negative airflow . Do you have anymore spots for fans?

That's what I was thinking!

Unfortunately not. The 650D is quite limited in fan slots. I was thinking of cutting out a space for a fan on the bottom of the case between the front HDD cages and the PSU, but that's not somthing I want to do just yet if I can help it.

Any ventilation on side panel? Hot air raises, yes, but I'd say when cpu is liquid cooled, one exhaust could be enought. If it isn't too much trouble, place some sort of thermometer inside case and try both options.

Unfortunately not. It's a bit of a awkward case. 

 

I shall try that!

top fans should definitely be exhaust since the warm air is rising to the top and will try to get out that way. Wouldn't wanna push it back down. So what you should do is set the rear 120mm fan as an intake - since you use an aio-watercooler this config is gonna work fine and that way you're probably gonna have something close to positive airpressure...

Top fans can bring some dust into the case if they are positioned as a intake 

I suggest you place it as a exhaust .

configure your airflow as to the air moves from the front to the back !

If there no filters then do exhaust if there is give intake a go but top normally is exhaust in my experience.

I would do pull(exhaust) for the radiator and have the exhaust fan filtered by buying a filter and having it as intake to get positive air pressure.

I didn't think to do this. I have ordered a filter for the rear fan!
