Id like to OC this to a stable clock speed and keep from overheating. My version of this card runs at 980 MHz

Specs:
i5 4460
AsRock H97M Anniversary mobo
MSI Armor 2x Radeon R9 380 4GB OC edition
EVGA 500W 80+ Bronze

And would case fans matter too much? I currently have 2 installed, 1 3rd party and the other came with the case.
