NVIDIA Fan Curves (GTX 1050 Ti Reference)

The user's GTX 1050 Ti runs a passive/quiet fan curve baked into the GPU BIOS.

Typical Stock Fan Curve

Temp Range Fan Speed Behavior
< 50°C 20-31% Idle floor — stays at minimum for silence
50-55°C 30-40% Start of ramp
55-65°C 40-60% Moderate load
65-75°C 60-80% Sustained load (gaming, rendering)
75-80°C 80-90% Heavy load
80°C+ 90-100% Thermal protection

Key Observations

  • 31% at 44°C is normal: The card was in P0 (active perf state) with 7% util, but 44°C is well below the 50°C ramp threshold. The fan stays at its idle floor.
  • Perf state matters: P8 (idle) → P0 (active) transition happens when the card has work. Temp can climb to ~50°C before the fan responds meaningfully.
  • Fan at 0% or [N/A]: Means the card relies on passive cooling or the fan hasn't spun up yet. Some Pascal cards have a zero-RPM mode below 50°C.
  • No user-side fan curve tool: Custom fan curves require nvidia-settings (X11) or third-party tools — not available in headless/server setups.

Power Draw Reporting

The GTX 1050 Ti (and other budget Pascal GPUs) cannot report power draw via nvidia-smi:

  • nvidia-smi --query-gpu=power.draw returns [N/A]
  • The card has a 75W TDP, runs off PCIe slot power only (no 6/8-pin connector), and lacks the power monitoring hardware/BIOS support
  • This is not a driver issue or misconfiguration — the sensor simply doesn't exist on this hardware
  • Cards that do report power: GTX 1060+, RTX series, and higher-end models with dedicated power sensors
  • What to tell the user: "The GTX 1050 Ti doesn't have a power sensor. It's normal — the card literally can't tell us. Nothing to fix."

What to Tell the User

If asked "why is the fan at X% when temp is Y°C":

  1. Check perf state (P0 = active, P8/P12 = idle)
  2. Compare temp against the curve above
  3. Under 50°C at 20-31% = perfectly normal, BIOS prioritizes quiet
  4. If temp exceeds 55°C and fan stays below 40%, something may be wrong (check for dust, thermal paste, or fan failure via nvidia-smi -q -d TEMPERATURE)
