Product overview
Noctua lists NH-U9 DX-4677 as a server/workstation CPU cooler for Intel Xeon socket LGA4677/LGA4710. In a dual-socket board both sockets have to carry the same model, and the BIOS has to be new enough to recognise it. Send the service tag and we will confirm the firmware revision as well as the chip.
We return an itemised quote within 48 business hours, and we say plainly when a part is constrained rather than quoting a date we cannot hold.

What you get ordering this from us
Ordered by part number
Quoted and supplied against NH-U9 DX-4677 specifically, so what arrives is what your build sheet asks for.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.

A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Questions buyers ask about this part
Is NH-U9 DX-4677 genuine and is the warranty intact?
Yes. It ships new in Noctua packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
Will NH-U9 DX-4677 work in my server?
Send the service tag. We check the platform's supported-CPU list and the BIOS revision it requires, and where the board is dual-socket we confirm what is in the other socket. A stepping the firmware does not recognise will not post.
Do you accept purchase orders and quote at volume?
Yes, POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.

Specifying a system, not just the part?
On a training or inference node the host CPU is sized around the accelerators it feeds, not chosen on its own.
