[HardHands]

So guys, I'm upgrading my PC and im not sure if i need to get a cooler and not sure which motherboard to get.

Cpu :i5 4690k 3.5 ghz. Will over click it if the game is demanding.
Mobo 😛lease suggest
GPU :ASUS STRIX GTX 960 DC20C or ASUS STRIX GTX 970 OC. will OC this too depending on the game.
Ram :2x4 DDR3 transcend jet ram 1333 1600 mhz
Psu :Corsair VS550 550 watts.
My cabinet does not have any extra fans.

ASUS Z97 Maximus VII Hero - Motherboard
Noctua NH-D15 - CPU Cooler

If you OC you will most definitely need a good cooler. This Noctua is one of the best Air Coolers. The Maximus VII Hero is one of the best budget Motherboards for serious overclockers.

Is the asus maximus VII ranger good enough?
And do i need a liquid cooler?
Is it for the processor or the GPU?
