It's a fantastic card and has exceed my expectations, however, I think the ASUS GPU Tweak software is bugged...I've noticed the fan controller eats up a huge chunk of CPU resources. I use MSI Afterburner to overclock and set fan curves and have absolutely no issues. Hopefully ASUS fixes whatever is bugged on their own software so I can give that another shot, but if not MSI's Afterburner still works great.
