Just finished my first build (gaming desktop) ill list a few specs here.
i5-3570k (at 4.2 GHz)
MSI GTX 660 Ti (PE/OC) (memory at 7000mhz)
8gb 1600mhz ram
h100i liquid cooler
all in a temptest 410 elite case.

My only problem at the moment is that my processor runs about 10 degrees hotter when I switch the airflow direction of the fans to what I want them to be (exhasting air from inside the case out the top), the fans are on top of the radiator, so all the hot air from the GPU is pulled through it, it runs about 60 degrees max on a gaming load, which I am more then fine with, but I am worried about it getting too hot in the summer time when the ambient tempurature will increase. The gpu runs at 70 degrees max on a gaming load (Guild Wars 2 max settings in 1920X1080)

My idea is that the extra airflow out the top will help cool the case for the gpu when it gets hotter in the summer. So thats why I have the fans they way they are now, and it is easier to keep dust out of my computer with this set up also. My other fans are 2 front 120mm fans pulling air into the case, and 1 rear fan blowing air out of the case. Thanks in advance for any tips you guys can give me.

I suggest 2 100+ CFM fan at the front and 1 80ish at the rear, this should give some airflow. And a 80 one to for the bottom. That should get your presure problems solved

Your hot air-cooled vga + MB vrm makes your in-case temp high. That hot air inside case is 'cooling' your radiator in exhaust setup, so your water temp is not good and neither is your cpu temp.

If you set your radiator fans intake, then your cpu temp will get better for sure but your gpu cooling will be not good.

One solution would be having a great amount of airflow inside case as Pedroc said. But you will have to tolerate a lot of noise.

So it's kind of trade-off here. I would go for radiator intake because gpu is more tolerant to heat than cpu generally

I remember on PCPP I saw a fan with 100 CFM with 20db of sound, thats not much is it?

Found it! Its the Bitfenix Spectra and it is a very powerful fan and quite cheap

I don't think you're talking about a 120mm fan. It may be possible to have large airflow and not much noise with 200mm+ fans. But whether his case allows them is another story.

Just found another one - http://uk.pcpartpicker.com/part/xigmatek-case-fan-xaff1255

This one is 120mm

Ok. This is a common trick that fan makers use. They give a range of rpms for their fan, publish airflow at max rpm and noise at min rpm. So it will NOT give you 90CFM at 26dB.

Oh, thats no very nice is it! Im out of ideas

I don't think that's shortening the lifespan of the CPU.
