So this is my first time having to do anything with overclocking. I have a Gigabyte gtx 970 (core: 1178mhz, boost:1329mhz). I would like to overclock my graphics card to 1500mhz for gaming. Would I need more fans to keep it cool? How high do you think the temperatures would get? Also my room is usually cold because I'm not too fond of heat. Would that help at all with the temperatures? I'm just worried I might screw up with something so I want to make sure I get it right the first time around.
