New Plugin: NvmlThermalSensors — Support for NVIDIA GPUs in TCC / Server mode (Blackwell, Tesla, RTX PRO)

[vladislavgoshko]

Hi everyone! 👋

I've developed a new plugin for Fan Control to solve a specific issue with professional and server-grade NVIDIA GPUs.

🔍 The Problem

Standard Fan Control NVIDIA support relies on NVAPI. However, when a GPU (like the new RTX PRO 6000 Blackwell or Tesla cards) is switched to TCC (Tesla Compute Cluster) mode, it stops being identified as a VGA device and disappears from NVAPI. This often leads to the "No GPUs found" error in Fan Control.

🛠️ The Solution: FanControl.NvmlThermalSensors

This plugin uses the NVML (NVIDIA Management Library) — the same interface used by nvidia-smi. It can see and report temperatures for GPUs regardless of their mode (WDDM or TCC).

🚀 Supported Hardware

• NVIDIA Blackwell Architecture (RTX PRO 6000 Blackwell, etc.)
• NVIDIA Ada Lovelace PRO (RTX 6000 Ada, etc.)
• NVIDIA Tesla / Ampere / Hopper (A100, H100, etc.)
• Any NVIDIA GPU running in TCC mode.

📦 Quick Start

1. Download the FanControl.NvmlThermalSensors.dll from the repo.
2. Place it into your Fan Control Plugins folder.
3. Restart Fan Control — your GPU temperature should now appear!

I'd love to hear your feedback or if this helps you with your server/workstation setups!

Sent you a note on your repo. I was not able to get this to load using FanControl 272 Net 4.8 version. Not sure if its tied to the other version of FanControl or not. I do have the NVIDIA SMI drivers loaded. My RTX Pro 6000s are in MCDM mode.
