gpu-cooling

This project is a compact USB-to-PWM fan controller based on the ATtiny85, built for GPU passthrough setups where the host cannot read GPU sensors. A VM reads GPU temperature and drives the fan via a USB CDC serial interface, enabling simple external temperature control.

Arduino Nano GPU fan controller with RPM-based temperature curves, calibration, and safety alerts. Includes a lightweight Ubuntu daemon and an SSH-friendly terminal UI for NVIDIA and AMD GPUs.

This is a simulation of the Founders Edition 5090 Nvidia GPU:

3D-printable push-pull fan duct for a 4-GPU V100 SXM2 NVLink carrier board (STL, STEP, build123d source). CERN-OHL-P-2.0.

Implements alternating fluid-solid strategy for orders of Magnitude speedup in Electronics Cooling CFD simulations

ESP8266 + Linux fan controller for NVIDIA Tesla SXM2-to-PCIe adapter blower setups, with GPU temperature control, tach feedback and fail-safe handling.

Memory-junction-aware fan control + thermal kill-switch for headless NVIDIA GPUs (GDDR6/GDDR6X). Fixes the factory fan curve that ignores VRAM temp. No X server / Coolbits.

GPU monitor for local LLM rigs -- btop-style TUI, per-process VRAM for Ollama/vLLM, thermal automation, Prometheus + Grafana
