The SecuFirm2 mounting-kits are backwards compatible with most Noctua CPU coolers manufactured since 2005 and will be available via resellers and free of charge via Noctua's website after uploading a proof of purchase.

"We were the first heatsink manufacturer to provide its customers with free mounting upgrades in 2006 when AMD introduced the AM2 socket and we've continued this policy with several generations of Intel sockets. Now we're glad to offer free mounting upgrades for the new AM4 platform," says Roland Mossig (Noctua CEO). "It makes us proud that so many customers who bought their Noctua cooler five or even ten years ago, and used it on several platform generations, are still so satisfied with it that they want to keep running it on the latest CPUs. Keep enjoying your Noctua coolers on AM4!"

Noctua will offer two different SecuFirm2 mounting upgrade kits for AM4: the NM-AM4-UxS kit for NH-U14S, NH-U12S and NH-U9S, and the NM-AM4 kit that supports most other retail cooler models manufactured since 2005 (NH-C12P, NH-C12P SE14, NH-C14, NH-C14S, NH-D14, NH-D14 SE2011, NH-D15, NH-D15S, NH-D9L, NH-L12, NH-L9x65, NH-U12, NH-U12F, NH-U12P, NH-U12P, SE1366, NH-U12P SE2, NH-U9, NH-U9B, NH-U9B SE2, NH-U9F) except for the NH-L9i/NH-L9a series low-profile coolers. In addition to the NM-AM4 and NM-AM4-UxS, Noctua also aims to offer an upgrade-kit for the NH-L9a later this year.

The SecuFirm2 mounting system for AM4 has been tailor-designed for the new socket in order to ensure optimal compatibility, perfect contact pressure and easy, straightforward installation. Both the NM-AM4 and the NM-AM4-UxS kit include two different sets of mounting bars, which allows the users to choose the orientation of the cooler according to their preferences in order to ensure an optimal alignment with the airflow path inside the case.

In order to obtain the kits free of charge via Noctua's website, users are required to upload a proof of purchase (electronic version, scan or photo of the invoice) of an AM4 motherboard or AM4 CPU as well as an eligible Noctua retail CPU cooler (server and workstation coolers of the DX and DO line are excluded from the free offer). Users who have lost the invoice for their Noctua cooler may write their full name and the current date on a piece of paper, take a photo of the paper next to their cooler and upload it as proof of purchase. Depending on the user's location, shipping will usually take 1 to ­4 weeks.

For users who need the kit urgently or do not yet have a proof of purcchase of an AM4 CPU or motherboard, the NM-AM4 and NM-AM4-UxS kits will also be available via selected retailers and e-tailers such as Amazon at a suggested retail price of EUR 7.90/USD 7.90.
