Hi, I recently built a pc with a new mid-atx case and I'm wondering why I'm getting higher temperatures with my build;

i5-4670k - only a few months old never overclocked.

EVGA - 80 Plus 600W ATX

Cooler Master Hyper T2 - CPU cooler - Not so much the issue as the 1070 is running hot I have the option to use a liquid cooler up to 240mm in the top of the case at the expense of two 120mm fans.

Asus Dual GTX 1070 - having higher than normal temps running this for more than an hour I would be pushing 78*c with the odd warning spike of 82*c playing longer.

As for the fans that you will see in the diagram I still can add two more 120mm fans if needed or one liquid cpu cooler

Wanted to get input of how to get better airflow and temps.
