my case is a corsair 650D here is a diagram of how i have my airflow right now:

i have my psu intake inside the case for aesthetic reasons and i would prefer to keep it there.

should i change the top to intake and the front to exhaust? is it fine how it is? any other thoughts?

For me I always have the top set to exhaust as you do. Depending on your video card, you might want to switch the back and front. If I have video cards that dump air into the case I have the rear to pull air in and the front to exhaust. If the cards dump the air out the back then I follow suit with the rear fan and have the front as intake.

Just my logic to have all fans on a side blow the same direction so you don't get heated air just exiting the case getting sucked right back in.
 
Your setup is fine except the PSU air direction,it will suck the warm/hot air from the video card and interior.

But if you want to keep it that way then there's nothing to change.
 
Can the PSU be repositioned so that it acts as an intake for fresh air from outside? I would do that if possible and make the push/pull configuration an exhaust. You will probably need a side fan as well pushing fresh air inside. Always keep in mind that heat rises.

My 2 cents.

Isnt that alot of hot air from the H60 coming in? I know you have an exhaust right there but I always thought it was best to get rid of hot air asap.
 
If you leave it this way consider making custom duct work to keep the H60 heat from contaminating the rest of the box. Make sure you have a quality power supply rated well above what you need so it will handle the higher temps it will see.
 
switched the fans on the h60, tried to flip the psu but it would require me to make my wires over again... i think that if my temps are too high after sli i will just get the mesh side panel and another bitfenix spectre pro 200mm for the side panel. place it as intake down by the gpu's and psu to get them more cold air.
 
Like others have said, looking at that case it appears you can have the PSU bring in air directly from the bottom of the case, so flip that one around.

The thinking would be that you are pulling in fresh, cool air from directly outside the case rather than pulling warm internal case air through the radiator. I read some review where they did tests on Push vs Pull vs Push/Pull and Intake vs Exhaust and found that Intake was at least a few C (maybe more) lower on the CPU than Exhaust for those closed-loop radiators.

However, if you are worried about GPU temps more than CPU, exhaust would make more sense.
 
i would personally mount the h60 on the top of the case because heat rises. that is the one rule i use with my cases and everything stays under 55C overclocked.

Like Maverick said, it is a good setup if you were focused on getting some extra cooling on the CPU. I personal would have the H60 mounted on the top pushing air out, another 120mm next to it as an exhaust, the read as exhaust, and a nice 200mm in the front sucking air in.

Also, definitely flip the PSU. The vent/screen on the bottom is there for a reason.
 
You never want air entering from the rear of your case. The PSU/GPU blows out the back. You don't want to suck that back in.

Front is the intake along with any passive intake (holes in the side of the case) then the top, rear and PSU blow out the back. The fan of the PSU typically points down if there are grills there to pull in cool air. You don't want your PSU pulling in hot air either.
 
mine is similiar except i have an exhuast in the back instead of a push pull and i'm using a noctura d14 and not front intake
