A:Answer Hi TandyTRS80,
You may be inducing further heat with your overclocking settings and you typically raised the voltage in your CPU. While this cooler is very efficient, you may be exceeding its cooling capabilities with your specific CPU and settings. We do offer other coolers with higher cooling capabilities that may be more suited for your situation, such as our Elite Capellix or Elite LCD series. If you'd like to learn more about our other offerings, please feel free to reach out to our support and we'd be happy to assist you with further assistance. support.corsair.com
