Best cooling setup for custom PC build

I have a
•corsair 780t case
•evga gtx 1080 hybrid/ACX3.0(air cooled) [still haven't decided]
•i7-7700k
•corsair 115i (280mm radiator)

My case has
•2 top mount fan areas up to 140mm
•1 rear 140mm fan mount
•1 bottom fan mount area (prefer not to use that
•2 front 140mm or 3 120mm fan mount areas

How would you setup the fans and radiators in my build to provide the best cooling. Choose whether to use an air cooled or AIO (120mm rad) graphics card in your solution because although I think the AIO option would be cooler (with regard to heat dissipation not style :) ), I do not want to get it if it will be bad for the cases overall cooling.

I will be overclocking slightly (few hundred Mhz), but I may possibly overclock to 5Ghz in a few years time.

Please help cause I am a complete beginning to PC builds (because in the past I have worked with prebuilt gaming PCs) and there are so many different ways all over the internet :)

EDIT: Could you actually tell where each of the rads and fans would go (I have listed the parts above) and whether you would keep rads in intake or exhaust DON'T just give generic answers pls

  1. Front, side, bottom are intakes, back and top are exhaust.

  2. Mount your CPU radiator to the top fan mount exhausting out.

    Put an exhaust fan on the rear and 2 140mm intake fans on the front. You can leave the bottom empty.

    If you were to get a liquid cooled GPU I would replace the rear exhaust fan with it.

  3. Does anyone else have an opinion. I appreciate the previous post, but I am not sure if it is the best for cooling as there will not be an exhaust (if the GPU uses up the rear exhaust) for the heat generated by the motherboard and RAM

    Since you will be placing a top exhaust fan the air will flow out there. I'm not a fan of liquid cooling GPU's, but you have no better option than to place your AIO fan at the rear spot IMO.

    The motherboard and ram generate minimal heat. Its really only the CPU and GPU that generate any real heat, The design I gave you provides a positive pressure setup leaving a lot of cool air in the system which then flushes out. it also takes advantage of the natural tendency of heat to rise. If you put the AIO cooler in any other spot it would defeat that purpose.

    Now that said there is another way to do this. You can mount the AIO cooler to the front and have it exhaust out that way, with an intake fan on the bottom and an exhaust fan at the rear, and an exhaust fan on top (and put the GPU cooler to the rear when you get it). This is a negative pressure setup, this does tend to draw dust into the system, but some do argue that it cools better. My system is set up this way but more out of necessity due to the design of the case I got. Whatever it looks cool lol.

  6. If I did choose your initial setup, where would the minimal RAM and motherboard heat get extracted??

    The rear exhaust fan or through the radiator on top. Heat rises but will take the path of least resistance.

    You really shoudn't be worried about the heat those components produce ;)

  9. So no one would choose intake for the AIO. Is exhaust the preferred option? :??:

    you want to flush the hot air from the radiator out, not into the case.
