Noctua Releases First Thermal Paste Application Recommendation for Ryzen 7000

as you tweeted @momomo_us, Noctua has revealed the first thermal paste application recommendations we’ve seen so far for AMD’s new Ryzen 7000 CPUs and their associated ‘octopus’ shaped IHS. For Ryzen 7000, Noctua recommends a single dot of 3-4mm in the center for good coverage across the IHS.

Dot applications are nothing new and are probably the most popular application technique to date. However, for Noctua, this is a significant departure from the recommended 5 dot pattern for similarly sized AM4 CPUs (IHS with 4 small dots in the corners and 1 large dot in the middle). Change.

AMD intentionally built the AM5 with the same dimensions as the AM4 for cooler compatibility, so it’s interesting to see Noctua recommending different thermal paste applications for both sockets. In fact, Noctua specifically treats his AM5 as a smaller “CPU size” compared to his AM4, and this is the reason behind the difference in thermal paste application.

However, Noctua may be right in choosing the AM5 dot pattern. The Ryzen 7000 features a very unique IHS design never seen before, it features an octopus shape and from the IHS he cuts out 8 slots and on his PCB of the CPU is for capacitors We have space. All of AMD’s older designs featured a perfectly linear box design for his IHS, like that seen in the AM4.

The cutout significantly reduces the Ryzen 7000’s IHS surface area. This is probably why Noctua changed his thermal paste recommendation from his 5-dot pattern on his AM4 to his 1-dot. Regardless, the single dot still works with AM4 and similarly sized sockets, so I have no doubt it will work well with AM5.

The question that remains now is whether the edges of the IHS that extend beyond the cutout should be covered with thermal paste, or whether it makes a difference. Unfortunately, we don’t have an answer for that at the moment, but it’s not absolutely necessary if you’re going to buy Noctua’s application method.

I’m curious to see what AMD’s official recommendations will be, and what we find in our own testing. However, we’ll have to see what the outcome will be until the Ryzen 7000 launches in his September. looking forward to!
