I am getting a corsair h105 and plan on getting corsair aftermarket fans. Can anyone recommend a way to set up the fans in my case and what size too use, cause I'm a bit confused? I keep reading that people say intake from front, bottom, and side. As well as exhaust from the top and the back. Where I'm. Confused is if I mount the 105 up top does it still act as an exhaust, and I'm going to mount the power supply on the bottom, so does that as an intake? Any help would be greatly appreciated

first this case could support up to the h 80 i so you could put 2 fan in the front as intake and one on the back as outake then the h 80 i on top as exaust below the radiator http://www.corsair.com/en-us/carbide-series-300r-compac... and the case already have a 120 mm fan in front and a 140 mm fan in the back .

Isn't the h105 better than the h80i? The case can fit a bigger fan than just a 120 or 140 single radiator

shure the 105 is better but that not what they have on the specs you may contact them to see if it will fit before buying it .

I have the case already there is screw holes up top for a 240mm and 280mm radiator and pcpartpicker showed that they were compatible. I have seen though that many people mount the smaller 120 and 140mm radiators on top rear exhaust port. Should I consider doing this with the h80i or h90 like you suggested

2 intake fans in front, top mount the h-105 as exhaust, and that's all you want. No rear exhaust. Heat rises under normal operation, all you want to do with exhaust is help that. By adding a rear exhaust you are effectively trying to force the hot air sideways, against the natural flow. In cases that do not have top exhaust vents, a rear exhaust works well because the hot air 'pools' at the top of the case, but your case has top exhaust ports, so there is no pooling. If you do add one, you will lower the efficiency of the radiator, as the fan in the upper rear will be drawing on less air, as the rear exhaust has unrestricted airflow (no radiator to push through) so will have greater suction.
