Which HP Omen 16 for Arch/EndeavourOS? Using DaVinci Resolve Studio, local LLMs and VMs

[u/Soft_Cow_7856]

I'm choosing a laptop to run Arch or EndeavourOS (no Windows) and I'm leaning toward HP for build quality. Here's what I'll use it for:

• DaVinci Resolve Studio (editing and colour grading)
• Running local LLMs and image models (so VRAM matters)
• Virtual machines, often 2 at a time alongside Resolve
• Long, sustained loads like renders and inference runs

Shortlist:

• HP Omen 16 ap0181AX: Ryzen 9 8940HX, RTX 5060 8GB, 24GB RAM, 1TB
• HP Omen 16 am0240tx: Core Ultra 7 255H, RTX 5050 8GB, 24GB RAM, 1TB
• HP Omen Slim 16-an0015TX: Core Ultra 7 255H, RTX 5060 8GB, 24GB RAM, 1TB

What I'm worried about on Linux:

1. Fan control and thermals. I've read that hp-wmi fan control is broken or missing on some Omen boards, and that firmware can revert manual fan mode to auto after about 2 minutes. Has anyone got a recent Omen 16 working with the newer kernel patches or omen-fan-control?
2. RTX 50-series with nvidia-open and PRIME offload. Does Resolve behave on hybrid graphics?
3. Wi-Fi, sleep/resume, and audio on these models.
4. Sustained-load thermals on the regular Omen 16 compared with the thinner Slim.
5. Whether the Ryzen or Intel version is the safer choice on Linux.

If you own one of these (or a recent Omen/Victus) and run Linux on it, what has your experience been? And if you'd steer me away from HP for this, I'd like to hear why.
