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. Reads temperature from all temp*_input sensors under /sys/class/drm/card{N}/device/hwmon/
2. Compares against configured min/max temperature thresholds
3. When temperature exceeds the range, scales TDP down via amd-smi
4. When temperature drops below the range, restores TDP to maximum
5. Changes are applied in configured step increments to avoid abrupt power shifts

Requirements

• Node.js (v14+, for fs/child_process only — no npm packages)
• amd-smi — AMD Software (pipx install amdgpu-tools)
• root — required for setting power limits

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
}

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)
