Noctua introduced its new NM-DD1 direct die kit. Developed in cooperation with professional overclocker and direct die cooling expert Roman “der8auer” Hartung, the NM-DD1 is a mounting spacer kit that makes it possible to use a wide range of Noctua CPU coolers on delidded AMD AM5 processors. Removing the processor’s integrated heat spreader (delidding) and putting the heatsink directly onto the dies allows for much more efficient thermal transfer and can thereby lower CPU temperatures significantly, with typical gains in the range of 10-15°C.
Removing the CPU’s integrated heat spreader (delidding) and putting the heatsink directly onto the dies using liquid metal thermal compound significantly improves thermal transfer and can typically reduce CPU temperatures by as much as 10-15°C. This increased thermal headroom can either be used to drastically reduce fan speeds and noise levels or, if the CPU allows, to achieve higher turbo boost frequencies.
For further performance gains, the NM-DD1 can be combined with Noctua’s new offset AM5 mounting bars (NM-AMB12, NM-AMB13, NM-AMB14, NM-AMB15) that allow users to achieve lower temperatures not only on regular AM5 CPUs, but also on delidded ones as the pressure will be more concentrated over the CCDs. Typically, using the offset mounting option with direct die cooling can yield additional gains of up to 2°C.
