"Overclocking performance was really good using the NH-D15. The 4.6Ghz overclock we use for testing is usually enough to overstress many heatsinks to the point where the C/W numbers will begin to change. With the NH-D15 we noticed that the number was identical between standard and overclocked tests which are a good indication for any heatsink. The temperature variance also remained the same between the single and dual fan tests which can be seen on the temperature charts. Overall the NH-D15 might be large but satisfies both the silent cooling and performance roles quite nicely."
