Product overview
NH-U9 TR4-SP3 is a Noctua premium CPU cooler for AMD sTRX4/TR4/SP3 sockets. 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.
If the part is wrong for your platform we will say so and suggest the one that is, which is cheaper for both of us than a return.

What you get ordering this from us
Ordered by part number
The order is placed against NH-U9 TR4-SP3, not against a description of it, so there is no room for a substitution you did not agree to.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
Questions buyers ask about this part
Is NH-U9 TR4-SP3 genuine and is the warranty intact?
Yes, new and sealed, with the Noctua warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will NH-U9 TR4-SP3 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. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.

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.
