I was planning to install Nobara tomorrow, i have been using copilot to bounce of my questions wich led me to believe Nobara was the right choice, claiming i could force global FSR4 using Gamescope and everything would run smoother

Now i am seacond guessing the decision after running the conversation by Gemini as it's advice and facts/recommendations are very different.

I need some humans to help me evaluate and tell me what is the right move here, posting gemini's response below

I recommended staying on Windows 11 because Linux cannot run your Lian Li L-Connect 3 software natively, which directly breaks your primary goal of controlling fan curves based on GPU temperatures. [1]

Additionally, your Ryzen 9 9950X3D utilizes a complex dual-CCD design that relies heavily on Windows-exclusive drivers to guarantee peak gaming performance.

Here is the exact technical breakdown of why Windows 11 remains necessary for your specific hardware goals.

The Lian Li Fan Curve Roadblock

Your main requirement is tying your Lian Li fan speeds directly to your GPU's temperature.

L-Connect 3 is Windows-Only: Lian Li does not develop software or drivers for Linux.

The Linux Alternative is a Project: To control your fans on Nobara, you would have to use community-driven command-line tools like CoolerControl. While excellent, these tools often struggle to read proprietary USB controller data from newer graphics cards like an RX 9070 XT. If the software cannot read the GPU sensor, your fans will default to a flat, unsafe speed.

The 9950X3D Core Allocation Problem

Your processor has 16 cores split into two separate 8-core dies (CCDs). Only one of those dies features the gaming-focused 3D V-Cache.

Windows Automation: Windows 11 co-developed a specific AMD chipset driver that works with the Xbox Game Bar. The exact microsecond a game launches, Windows automatically parks the standard cores and forces the game entirely onto the 3D V-Cache cores.

Linux Manual Tweak Fatigue: The Linux kernel is highly efficient, but it lacks an automated, foolproof equivalent for day-one dual-CCD X3D chips. Games will frequently spill over into the standard cores, resulting in micro-stutters and a noticeable drop in your 1% low frame rates unless you manually bind the game processes using launch arguments.

Early X870E Platform Bugs

Your ASRock X870E Nova is a top-tier motherboard, but the X870E chipset is still relatively fresh. Motherboard manufacturers focus their engineering teams entirely on fixing Windows stability bugs first. Running a massive 64GB array of DDR5 at 6000MHz via EXPO requires rock-solid BIOS and memory controller stability, which is significantly more prone to random kernel panics and sleep-mode crashes on Linux during the first year of a motherboard platform's life cycle.

If you still want to dual-boot Nobara Linux on your second 4TB M.2 SSD just to experiment with it safely without deleting Windows, would you like me to walk you through how to configure that safely?
