It is always best when your PCI-e cables come directly from your PS. Each PCI-e plug has a dedicated PCI-e cable. If you double up your 12V PCI-e you can starve the GPU of power.

EDIT: ok... this are my results without overclock. I tried Fire Strike Extreme and got 11051 score. But temps go over 65° and reach about 73-75°, fans are setted with default "aggressive" profile from EVGA Precision X and become very very noisy, stayed at 98% during benchmark... No artifacts, but too much heat and noise.
What should I do?
You can O/C memory also but just do it after you've reached your max stable GPU O/C. This BIOS should allow max memory overclock and max GPU overclock at the same time.
The noise is one of the biggest reasons people water cool. The best advice I can give is that OTHERS are able to keep the card cooler than that. You want to try and keep it 65C or below. There are some tricks/tips you can think about
(1) Test with your case OPEN. Most people don't have a real good understanding about airflow in a case. They focus on exhaust fans but don't balance intake with exhaust. You need to move air through the case, not attempt to just exhaust the hot air. If you don't balance this it will also create air noise from either too much positive pressure or too much negative pressure.
(2) Clean the case, blow it out with compressed air (an actual compressor is best just be careful not too much pressure on fans) to ensure that dust and blocked vents are not working against you.
(3) Tie up your wires very neatly in the case, hide as many wires as you can. If you notice my PC pics, it is almost completely open inside, no airflow restrictions at all so air comes in easily and leaves easily.
(4) Use supplemental fans. Depending on you card and your airflow you need to figure out where to mount the extra fan(s). I nice trick I use is to take a quality 80mm fan (as large as the GPU size) and I push large tie-wraps through the screw holes. The width of the tie-wrap fits snug when you push through the hole. The top of the tie wraps on all 4 holes I use as little "feet" for the fan. Adjust and cut them all evenly and you can a fan with 4 little adjustable feet you can rest right on top of your GPU or somewhere else to get air blowing at it. This way the air your GPU is taking in has already been a bit pre-cooled.
(5) Ensure your case is placed where it is getting plenty of cool air. If you have it tucked away inside the cabinet of your desk, that = overheat. Make sure there is at least 2 feet all around your case and nothing is blocking air flow. Don't have it sitting under a window where the sun in hitting it.
(6) Re-arrange PCI-e slots if you can so there isn't anything directly over or under your GPU.
(7) Use a house fan to move air around the area of your PC is sometimes needed. It is almost SUMMER and we need to get creative.
Lastly, high overclocks = more performance = more heat so we have to adjust accordingly, This is expected
