amd-gpu-temp-control

amd-gpu-temp-control

Monitors AMD Radeon GPU temperatures via sysfs and dynamically adjusts TDP limits using upp to keep temperatures within a configured range.

Supported GPUs

AMD Radeon discrete GPUs with PowerPlay table support:

• Polaris
• Vega
• Radeon VII
• Navi 10, 12, 14
• Navi 21, 22, 23
• Navi 3x (experimental)

Not supported: AMD APU iGPUs (different PowerPlay control methods).

How it works

1. Discovers actual max TDP via upp get SmallPowerLimit1 at startup (fallback: 120W)
2. Reads temperature from all temp*_input sensors under /sys/class/drm/card{N}/device/hwmon/
3. Compares against configured min/max temperature thresholds
4. When temperature exceeds the range, linearly scales TDP down via upp PowerPlay table modifications
5. When temperature drops below the range, restores TDP to maximum
6. Changes are applied in configured step increments to avoid abrupt power shifts

Requirements

• Node.js (v14+, for fs/child_process only — no npm packages)
• upp — Radeon PowerPlay table tool (pipx install upp or build from source)
• root — required for writing PowerPlay tables

Install

sudo ./install.sh

Copies the script to /usr/local/bin/amd-gpu-temp-control and installs the systemd service.

Uninstall

sudo ./install.sh --uninstall

Removes the binary and service unit, stops the service.

Configuration

Default config path: /etc/amd-gpu-temp-control.json

{
  "minTemp": 70,
  "maxTemp": 80,
  "minTdpPercent": 10,
  "maxTdpPercent": 100,
  "tdpStepPercent": 10,
  "checkIntervalMs": 2000,
  "uppPath": "upp"
}

Parameter	Default	Description
minTemp	70	Lower temperature threshold (°C)
maxTemp	80	Upper temperature threshold (°C)
minTdpPercent	10	Minimum TDP percentage when throttling
maxTdpPercent	100	Maximum TDP percentage (full power)
tdpStepPercent	10	Maximum TDP change per cycle (%)
checkIntervalMs	2000	Temperature read interval (ms)
uppPath	upp	Path to the upp binary
