v1.1.0-rc.2

What's Changed

• docs: ledger graceful --stop on upgrade for 1.1.1 by @bitworks-io in #16
• fix: 1.1.0-rc.2 — resolve the RDNA1/2 INF's .\B026653 disk path by @bitworks-io in #17

Full Changelog: v1.1.0-rc.1...v1.1.0-rc.2

v1.0.1

Fixed

• A GPU installed in place of a removed one could come up with fan control disabled
  (the removed card's saved setting blocked it); fixed. If a card is already affected,
  enable it in Preferences.

v1.1.0-rc.1

What's Changed

• RDNA1 fan control and fan-state restore (1.1.0) by @bitworks-io in #15

Full Changelog: v1.0.0...v1.1.0-rc.1

v1.0.0

Lightweight AMD GPU Fan Control v1.0.0 — first stable release.

A tiny per-user Windows systray utility that drives AMD Radeon GPU fans toward a core-temperature target (default 65 °C) — a lightweight alternative to the AMD Adrenalin fan-curve UI. Publisher: Bitworks.

Highlights

• Automatic temperature-target fan curve, plus a manual fixed-speed mode — switch from the tray or Preferences.
• Safety first: over-temp emergency ramp to 85 %, sensor-loss fallback to the driver's automatic control, and hard fan bounds (20 % floor, 85 % ceiling).
• Multi-GPU aware (modern ADLX path; ADL fallback controls the primary GPU).
• Restores the driver's automatic fan control on exit.
• No runtime download, no admin rights — targets in-box .NET Framework 4.8 (Windows 10 1903+ / Windows 11).
• Code-signed via Azure Artifact Signing.

Install

Download and run LightweightAmdGpuFanControl-Setup.exe below. Validated on a Radeon RX 7900 XTX.

Note: Windows SmartScreen reputation builds over download volume, so a first-run prompt may still appear until it accrues.

v1.0.0-rc.8

What's Changed

• fix: installer closes running app before upgrade; Preferences OK applies+closes by @bitworks-io in #13

v1.0.0-rc.7

What's Changed

• chore: update in-repo links after repo rename → gpu-fan-control by @bitworks-io in #10
• ci: sign installer via Azure Artifact Signing (OIDC, gated on release tags) by @bitworks-io in #11
• ci: scope OIDC signing to the 'release' GitHub Environment by @bitworks-io in #12

Full Changelog: v1.0.0-rc.5...v1.0.0-rc.7

v1.0.0-rc.5 — Release Candidate

Release candidate for v1.0.0.

Download

LightweightAmdGpuFanControl-Setup.exe — per-user, no admin, no runtime download (in-box .NET Framework 4.8).
⚠️ Unsigned — SmartScreen: More info → Run anyway.

Changes since rc.4

• Installer can now close a running instance. The app is a system-tray program with no visible window, so an installer's Restart Manager couldn't close it — it only released the fan and then lingered, forcing you to kill it in Task Manager. It now shuts down cleanly on that request, so upgrading over a running copy just works. (Test: with the app running, run this installer — it should close the old copy and continue without Task Manager.)
• Help / Report links now point to the project on GitHub (repo is public): "Help / Fan control not working" → the README troubleshooting section; new "Report an issue…" tray item → GitHub Issues.

Still in this build (from rc.4)

• The fan now ramps down correctly (Automatic + Manual) — the driver-latch fix. Please keep confirming this on the 7900 XTX.

Requires Windows 10 1903+/11 x64 + AMD Radeon with Adrenalin.

v1.0.0-rc.4 — Release Candidate

Release candidate for v1.0.0. This one targets the core fan bug.

Download

LightweightAmdGpuFanControl-Setup.exe — per-user, no admin, no runtime download (in-box .NET Framework 4.8).
⚠️ Unsigned — SmartScreen: More info → Run anyway.

Fix in this build

• The fan now ramps back DOWN (both Automatic and Manual). Root cause (from your hardware logs): the app was writing the lower fan curve, but the AMD driver latches the manual setpoint at its highest value and ignores a lower curve until manual control is released — which is exactly why closing the app dropped the fan. The app now briefly releases and re-applies whenever the target decreases, forcing a downward re-evaluation.

Please verify

• Automatic: under load the fan ramps up; as the GPU cools below your target it should now come back down to the minimum (previously it stayed high).
• Manual: lowering the fixed speed should now reduce the fan.
• The log.txt [fan] applied … lines now include releasedForDecrease=true on decreases — that confirms the new release-and-reapply path ran.
• Watch for any brief fan "pulsing" while actively cooling from load (the release/re-apply happens each step during ramp-down) — tell me if it's noticeable and I'll damp it.

Carries rc.3's dialog/DPI fixes, Apply button, and GPU-monitor contention mitigation. Requires Windows 10 1903+/11 x64 + AMD Radeon with Adrenalin.

v1.0.0-rc.3 — Release Candidate

Release candidate for v1.0.0 — please test and report issues before the final release.

Download

LightweightAmdGpuFanControl-Setup.exe (~2.7 MB) — per-user install, no admin, no runtime download (in-box .NET Framework 4.8 on Win10 1903+/11).
⚠️ Unsigned — SmartScreen will warn; More info → Run anyway.

Changes since rc.2

• Preferences & About dialogs no longer clip buttons/text on high-DPI displays (fixed the real cause — auto-sizing after DPI scaling).
• Apply button added to Preferences: OK applies + closes, Cancel discards + closes, Apply applies and keeps the window open.
• Adaptive GPU-monitor contention mitigation — if GPU-Z / MSI Afterburner / HWiNFO / AIDA64 are running, the app reduces its sensor polling, stops redundant fan writes, and warns once. This limits the GPU sensor-bus (I2C/SMBus) contention that can destabilize the AMD driver and cause crashes / "green screen" when several GPU tools poll at once. Note: contention is multifactorial — for best stability, avoid running multiple GPU monitors together.

Requirements

Windows 10 (1903+) or 11 x64 · an AMD Radeon GPU with AMD Software: Adrenalin Edition (manual fan tuning available).
