Improved heat transfer
Removing the CPU’s integrated heat spreader (delidding) and applying liquid metal thermal compound allows the heatsink to make direct contact with the dies, significantly improving thermal transfer. This can typically reduce CPU temperatures by 10–15°C, enabling lower noise levels or higher boost frequencies.

 Precision-made spacers and screws
Includes heat-resistant ABS spacers and corresponding screws to compensate for the removed heat spreader height, allowing proper installation of Noctua coolers. Please note that delidding tools, CPU protection frames, and liquid metal thermal compound must be purchased separately.

 Ideal for use with offset mounting bars
Compatible with Noctua’s AM5 offset mounting bars (NM-AMB12, NM-AMB13, NM-AMB14, NM-AMB15), which concentrate mounting pressure over the CCDs. When combined with direct die cooling, this can provide additional temperature reductions of up to 2°C.

 Compatible with most popular Noctua CPU coolers
Supports both single- and two-piece fastening brackets, making it compatible with most Noctua CPU coolers since 2005 (see compatibility tab), including popular models such as NH-D15(S), NH-D14, NH-U14S, NH-U12A, NH-U12S, NH-U12P, and NH-U9S.

 3D-print at home option
The included spacer designs can be 3D-printed at home using STL files available on Printables.com, allowing flexible customization for different mounting setups.

  Step-by-step guide available
Direct die cooling is more complex than standard CPU cooler installation and carries certain risks, but a detailed step-by-step guide is available to assist users through the process.

• The NM-DD1 is only compatible with AMD AM5 Ryzen 7000 CPUs.

• Not compatible with Intel CPUs. Installing Noctua coolers on delidded 12th/13th Gen Intel Core processors may damage SMD components and render the CPU unusable.
