thats my current setup (ghetto mod for NB heatsink)

3x 120mm front intake (1 is where the cd-bay would be)

140mm top exhaust
120mm rear
scythe ninja3 push/pull 2x1900rpm slipstreams

I'm going to get antec h2o 1250 soon and going go attach it to top as exhaust.

When i do that should i change the rear exhaust to intake so the rad can get fresh & cool air?

You can do that, but mind you that hot air rises to the top of your case. It may actually be better to exhaust that hot air with an exhaust than to put more air into your case.

I would keep it as exhaust as the hot air would be sucked out, if it was intake the hot air will actually go into your rad instead. As that would be the only exhaust. Causing temps to be higher. The rear fan actually sucks hot air away from your rad.

If you have any side fans though I would use them as intake.

Good luck-

With top mounted rads, I think its best to mount the fans as intake for cooler air being drawn thru them. I spent a couple days testing various configurations when I got my H100 and what worked best was front and side fans running as intake, the rear fan as exhaust and the H100 fans mounted underneath the rad drawing in. Axial fans pull better than push so this will work a little better.

People point out that heat rises so the top fans should be exhaust. That is true but thats true in static air. With fans blowing, the heat will go wherever its directed. With the rear fan running as exhaust not to mention the back of your case is likely mesh, the heat will easily be pushed right out with no problem.

Now let me add that your mileage may vary. My computer room is in my finished basement and its usually pretty cool in here so my ambient temps are probably cooler than a lot of people's so drawing that cool air in may work better for me than some dude that lives in Phoenix where its 150 in the shade. So try both ways and run some tests and find out what works best for your particular configuration. For me it was with the top as intake and it made about a 3C difference on my CPU temps under OCCT. That might not seem like much but it is especially if youre going to be overclocking.
