How to keep good airflow with 280mm radiator in front of case

Basically, I am looking to upgrade my CPU cooler and have fancied liquid cooling for a while. I know some will recommend air cooling but I'd rather not have a huge clunky heatsink on my CPU as my computer has a window and l like it looking clean, (pathetic right?). Anyway, I need a new cooler and my NZXT S340 has space for a 280mm rad in the front, however, I was wondering wouldn't this make the overall case temp higher? Sure the CPU will be cooler but if there isn't fresh air coming in anywhere but the radiator wouldn't it be warm?

tl;dr CPU too hot in some games (4690k - 80C hottest core - Far Cry 3, never this hot in other games) need to cool it better than stock heatsink.

Thought I might add specs anyway -

i5 4690k no OC
G1 Gaming GTX 1070
NZXT S340
2 simple case fans just now one back one front.
Looking to get NZXT Kraken X61?
 
Yes, a front mounted radiator will heat up the air going to cool your GTX1070. Not good.

What is your objective?
If you will not overclock, you do not need any sort of aftermarket cooler.
The stock cooler is not the best, but it will keep your cpu sufficiently cool if it is mounted properly.
You should be seeing about 10-15c. over ambient if the cooler is mounted well.
80c. is a bit hot, and the stock fan will be noisy.
But... 80c is some 20c below the point where the cpu will slow down or shut off because of heat.

If looks are that important to you, why not buy a good looking air cooler?
From a functional point of view, a Cryorig H7 will run quieter and cool better.
It is relatively small at 145mm tall:

A unique looking Zalman cooler might appeal top you:

If I were to watercool my cpu, I would consider some overclocking.
Also, If i did put the radiator in the front, would I notice a significant temperature increase on my gpu?
I'm 95% sure I mounted the stock fan properly, I mean, it's not too complicated.

Thanks for the reccomendations!
