Open Source C# Hardware Monitoring Software

Libre Hardware Monitor is a free, open-source system monitoring tool that provides detailed insights into your computer’s hardware health and performance. It tracks real-time metrics such as temperatures, fan speeds, voltages, clock speeds, and load across a wide range of components. The project includes both a Windows Forms application for visual monitoring and a reusable library for developers who want to integrate hardware monitoring into their own software. LibreHardwareMonitor supports modern Intel and AMD CPUs, major GPU vendors, storage devices, and network adapters. Built on modern .NET versions, it continues to evolve with frequent updates and broad community contributions. Licensed under MPL 2.0, it offers a transparent and extensible alternative to proprietary hardware monitoring tools.

Open Hardware Monitor is a free and open source hardware monitoring application designed primarily for personal computers. It provides real-time insights into key system metrics such as temperatures, fan speeds, voltages, load percentages, and clock speeds by reading directly from sensors embedded in CPUs, GPUs, motherboards, and storage devices. The tool supports a wide range of sensor hardware found on modern systems, including Intel and AMD processors, NVIDIA and AMD graphics cards, SMART temperature sensors on storage drives, and many motherboard monitoring chips. Users can view monitored data directly within the application, as customizable desktop gadgets, or through a system tray interface, making it easy to keep an eye on system health at a glance. OpenHardwareMonitor runs without the need for a traditional installation (it can be run portably) and on systems configured with the appropriate runtime (e.g., .NET or Mono).

CapFrameX is a performance capture and analysis tool designed for PC gamers and benchmarking enthusiasts, which records frametimes, frame-rates and various sensor data during game or application execution. It uses backend tools like PresentMon to log data and then exposes a comprehensive UI for analyzing the results: you can view charts of frametimes, historic graphing, stuttering analysis, L-shape graphs, input-lag overlays, and compare multiple capture runs side by side. Importantly, the tool also integrates with sensor inputs (CPU, GPU, VRAM, temps, etc.) and overlays statistics in-game via Rivatuner Statistics Server, so you get in-situ feedback while you run. For benchmarking, it supports aggregation, filtering, outlier detection, and export of records to CSV/Excel for further analysis or reporting. The project is suited for reviewers, hardware testers, and power users who want to dig deeper than simple FPS numbers and want to diagnose performance issues.

SIV by Ray Hinchliffe. 'System Information Viewer' is a general Windows utility for displaying lots of useful Windows, Network and hardware info - CPU info, PCI info, PCMCIA info, USB info SMBus info, SPD info, ACPI methods, Machine info, Hardware Sensors, Networked computers, Operating System Information and more. SIV is designed for Windows 11, 10, 8, 7, Vista, XP, 2012, 2008, 2003, 2000 and NT4. Windows 95, 98 and Me are also supported. SIV can also be used to control AIO devices, such as fans and LEDs. To do this, you need to specify the -AIOCTL command line qualifier. When -AIOCTL is specified, SIV will automatically do the EnhancedPowerManagementEnabled registry change and restart the USB device. SIV (System Information Viewer) uses pcidevs.txt for the PCI devices, usbdevs.txt for the USB devices, and mondevs.txt for monitoring pcmdevs.txt PCMCIA device descriptions.

Argus Monitor is a powerful fan-control and system-monitoring tool that gives you complete control over cooling behavior across your entire PC. It allows you to manage CPU, GPU, motherboard, and AIO fans using fixed values or advanced temperature-based control curves sourced from any sensor in your system. With multi-controller support, fan profiles, hysteresis, and temperature averaging, Argus Monitor offers smooth, precise fan adjustments with minimal noise fluctuation. The software also includes robust temperature monitoring for CPUs, GPUs, SSDs, RAM, and additional sensor channels. For supported devices, it provides RGB control as well as gadget and tray-icon displays for quick system insights. Lightweight, stable, privacy-respecting, and fully customizable, Argus Monitor is one of the most comprehensive PC cooling and monitoring solutions available.

SysGauge is a powerful system monitoring and performance analysis tool for Windows that delivers deep insights into your computer’s operation. It provides real‑time visualization of key metrics across multiple domains: CPU and memory usage, disk I/O, network traffic, and active processes. The application features a customizable dashboard with live graphs, gauges, and tables, letting you track trends and spot bottlenecks at a glance. SysGauge supports historical data logging for post‑analysis and capacity planning, and offers alerting for critical conditions (e.g., high CPU load, low disk space). It includes advanced process monitoring with detailed resource breakdowns, service status checks, and network connection tracking.

Network Asset Manager is a Hardware and Software Inventory Management application. It is simple to use and collects information on all hardware and software components of your PC's and Servers on the network remotely.

Manage and configure multiple routers from a single interface. Project is aimed at becoming a suite of utilities for Cisco network management. Mainly tested on: Cisco 1841 (revision 6.0) with 236544K/25600K bytes of memory.

Just a place to collect & share the scripts I've developed as an MSP for my various software systems, like PSA & RMM... and more from other like-minded MSPs who wanted to help others! No guarantee that everything is in PowerShell, C#, or even the latest version, so be sure to read the code comments and other documentation, as well as ask the community. You may even find discussions. -pat

An interactive monitoring utility that allows to watch the status of multiple servers including the hosting machine at once. The most comprehensive, easy-to-use and visually impressive WPF-based network monitoring application that is completely open-source and modular. Can be run as a windows service, acts as a server and allows remote HTTP management via browser, or can be run minimized, at background or from command line. Generates impressive interactive charts, logs and statistics, supports exporting Excel-compatible reports, text and CSVs, SQL data or SQL-Insert statements. Contains hardware information, bandwidth meter and usage, ping, whois, lookup, traceroute, port scanning, WOL (wake on LAN). Allows users to develop custom plug-ins.
