OmenCore is a free, open-source replacement for the parts of OMEN Gaming Hub people actually use: fan control, performance modes, GPU Power Boost, keyboard lighting, monitoring, an in-game overlay and cleanup of HP background software.
No account, no ads, no cloud telemetry (details), and OMEN Gaming Hub does not need to be installed. It talks to the laptop directly through HP's WMI BIOS interface, the embedded controller (via PawnIO) and, on Linux, hp-wmi and sysfs.

Released 2026-11-13. Update from inside the app (the update button in the header, or F5); settings carry over.
- Modes remember the whole machine. A performance mode can carry a fan preset or custom curve, GPU Power Boost level, refresh rate, lighting profile and charge limit, not only power limits. Game profiles that use a mode get all of it. Your 4.x modes load unchanged.
- Every greyed-out control says why: the model database, the firmware, a safety rule or runtime detection. The same reason goes into the diagnostics export.
- Faster start, lower memory. CPU detection no longer waits on WMI (about 2 s saved on a cold boot), and idle memory is around 100 MB. CI enforces both budgets.
- Interface refresh. The window follows the active mode's colour, zooms, follows Windows high-contrast themes, has screen-reader names on the navigation, and the shell is translated into Russian and Turkish.
- Safer updates. The updater checks each download against the release's
SHA256SUMSfile, and every release carries GitHub build provenance. - Safer uninstall and upgrade. The installer hands the fans back to the BIOS, so a fan left at Max no longer stays pinned.
- Settings migrate. A 4.x
config.jsonis upgraded, and the original is kept asconfig.json.schema0.bak.
Not in 5.0.0, planned for 5.1: signed binaries (Windows SmartScreen still shows "unknown publisher"), a UI that does not run as administrator, and translations for the remaining pages.
Full notes: docs/CHANGELOG_v5.0.0.md. Hardware-facing changes are marked pending confirmation until an owner reports them working on a real board.
| Area | What you get |
|---|---|
| Fans | Auto, Max, preset modes and custom temperature curves where the board safely supports them; one-click hand-back to the BIOS; guided fan verification |
| Performance | Quiet, Balanced, Performance and custom modes that also carry fans, GPU boost, refresh rate, lighting and charge limit; per-game profiles that switch automatically |
| GPU | GPU Power Boost and MUX switching on supported firmware; NVIDIA and AMD telemetry; opt-in NVIDIA laptop power unlock |
| CPU tuning | Intel undervolt and TCC offset, AMD power limits and Curve Optimizer where the model and BIOS allow them, with crash-safe test-apply |
| Lighting | OMEN four-zone and per-key keyboards, brightness and effects; Corsair, Logitech, Razer and OpenRGB devices |
| Monitoring | CPU and GPU temperature, load, power and fan speed, battery and memory; click-through overlay with RTSS FPS; live tray icon |
| Battery | Battery Care charge limit; automatic AC and battery profiles |
| Cleanup | Guided OMEN Gaming Hub removal, HP bloatware scanner, memory optimiser |
| Diagnostics | One-click export with model identity, capability reasons, fan history and firmware fan table, for fast and accurate bug reports |
| Linux | Command-line tool and desktop GUI over hp-wmi, ec_sys and hwmon |
OmenCore is built for HP OMEN and Victus laptops. Support is decided per board (the ProductId in Diagnostics), and anything not confirmed on a real board starts with conservative defaults.
| Hardware | Support |
|---|---|
| OMEN 15 / 16 / 17 laptops | Primary target: fans, modes, monitoring, lighting and power features, by model |
| Victus laptops | Fans, modes, monitoring and backlight; GPU power and undervolt often unavailable |
| OMEN MAX 16 / 17, OMEN Transcend | Supported; some lighting and power paths still need owner confirmation |
| OMEN desktops | Monitoring, modes and cleanup; fan writes are disabled for safety |
| Other HP and non-HP machines | Monitoring only; control features are not targeted |
If your board is not recognised, see Requesting support for your model.

| File | For |
|---|---|
OmenCoreSetup-5.0.0.exe |
Most Windows users. Installs the app and, optionally, the PawnIO driver. |
OmenCore-5.0.0-win-x64.zip |
Portable Windows use. Extract and run OmenCore.exe as administrator. |
OmenCore-5.0.0-linux-x64.zip |
Linux command-line tool and GUI, self-contained. |
- Download
OmenCoreSetup-5.0.0.exe. - Run it. Windows may warn about an unknown publisher because the installer is not yet signed: choose More info, then Run anyway. You can verify the file first (see below).
- Keep PawnIO selected unless you only want monitoring and the WMI features.
- Start OmenCore from the Start menu.
Needs Windows 10 (19041 or later) or Windows 11, x64. The .NET 8 runtime is included. The app runs as administrator because WMI BIOS and embedded-controller access require it.

Every release publishes a SHA256SUMS file and a .sha256 file next to each download, computed by the release workflow from the exact files it attached. Each file also carries GitHub build provenance, which proves it was built by this repository's workflow from the tagged commit:
gh attestation verify OmenCoreSetup-5.0.0.exe --repo theantipopau/omencoreAntivirus warnings are covered in docs/ANTIVIRUS_FAQ.md and docs/DEFENDER_FALSE_POSITIVE.md.
| Problem | What to try |
|---|---|
| A control is greyed out | Open Advanced, or export diagnostics (capability-reasons.txt): it says why, and whether the reason is the model, the firmware or a safety rule |
| Fans have no effect | Diagnostics → Guided Fan Verification, then export diagnostics |
| Fans stay loud | Pick any fan mode, or Restore OEM Auto, to hand control back to the BIOS |
| PawnIO unavailable | Re-run the installer with PawnIO selected, reboot, and run OmenCore as administrator |
| Lighting does not apply or resets | Close other HP lighting tools; export diagnostics so the keyboard backend is on record |
| Battery Care fails | Connect AC power and try again; export diagnostics with your BIOS version |
| Overlay hidden in a game | Use borderless or windowed fullscreen; Windows cannot draw overlays over exclusive fullscreen |
| Linux: permission denied | Run the command-line tool with sudo |
Windows logs are in %LOCALAPPDATA%\OmenCore\. On Linux, ./qa/collect-linux-triage.sh or sudo ./omencore-cli diagnose --report collects a bundle.
Open Diagnostics → Export and attach the zip to a GitHub issue or post it on Discord. Say what you did, what you expected and what happened. The export contains your model identity, capability reasons, fan history and logs, which is almost always enough to find the cause.
If Diagnostics shows Unknown <Family> Model or "Family fallback / Low confidence", your laptop is running on generic defaults. To get a proper entry:
- Copy the Model Identity Summary from Diagnostics in full.
- Note which features work and which do not (fans, modes, Battery Care, lighting).
- Open a GitHub issue with both, plus a diagnostics export.
New entries start conservative and are widened as owners confirm each feature on real hardware.
git clone https://github.com/theantipopau/omencore.git
cd omencore
dotnet build OmenCore.sln -c Release
dotnet test OmenCore.slnRelease artifacts: pwsh ./build-installer.ps1 -SingleFile (Windows installer and portable zip, needs Inno Setup) and pwsh ./build-linux-package.ps1 (Linux zip). Both write to artifacts/ with a .sha256 next to each file. The version comes from VERSION.txt only.
The test suite (2,100+ tests) checks the logic: model resolution, fan-curve and safety math, the diagnostics export, view-model state and regressions pinned to real reports. It cannot prove a particular board's firmware responds the way the code expects, which is why hardware-facing changes stay pending confirmation until an owner reports back.
The most useful contributions are diagnostic exports from real boards, confirmation that a pending fix works on your laptop, Linux sysfs snapshots, translations and focused bug fixes.

OmenCore is provided as-is. Fan control, embedded-controller writes, undervolting, GPU power changes and MUX switching can affect stability and hardware behaviour. Read the warnings in the app, and leave experimental options off unless you know how to recover.
OmenCore is an independent project and is not made by or endorsed by HP.
