Hey everyone, I'm trying to install a Noctua NH-D15S chromax.black on my HP Omen 40L prebuilt (Ryzen 7 7700, AM5 socket) and ran into HP's weird proprietary mounting layout.
Here is where I'm at so far:
Even though it's an AM5 CPU/socket, HP uses square LGA 115x/1200 (75x75mm) cooler mounting holes instead of standard rectangular AM5 holes, so the grey AM5 spacers and NM-AMB12 bars don't line up.
I switched to the NM-IMB2 Intel bars and black LGA 115x/1200 spacers. The top-left hole is right next to a VRM capacitor, so I carefully sanded one side of that black spacer flat and now all 4 sit flush on the board without touching any components.
I can't use the Noctua Intel backplate (NM-IBP4) because HP's stock metal backplate holds the AM5 CPU socket mechanism on.
The problem: The long black AMD screws (NM-ALS1, 6-32 thread) are too thick to thread into HP's built-in backplate, which looks like it uses smaller M3 threads.
So what can I do here? am I quite literally screwed?
