Noctua NH-D14 Lower Noise Heatsink Review
In this review Frostytech will be testing out Noctua's massive dual-fan NH-D14 heatsink and comparing it against 280 other heatsinks. The big NH-D14 heatsink stands as tall as a modern tower heatsink but is twice as wide. The dual-fan set up more than makes up for that bulk by proving itself to be an excellent low noise solution capable of performance cooling. This heatsink currently ranks near the top of Frostytech's Top 5 Heatsinks chart.
