Overview
Description

AIDA64 is a comprehensive system information, diagnostics, and benchmarking tool designed for Windows, Android, iOS, and other platforms. It provides detailed hardware and software insights, helping users monitor system stability, temperature, voltages, and performance metrics. Trusted by PC enthusiasts, IT technicians, and hardware reviewers worldwide, AIDA64 includes specialized benchmarking modules for memory, CPU, and GPU performance analysis, alongside extensive hardware monitoring and external display support.

SpeedFan is a classic hardware monitoring utility designed for Microsoft Windows that interfaces with digital temperature sensors, voltage inputs, and fan controllers. It reads data from motherboards connected via the SMBus to give users detailed insights into their system's thermal performance. Beyond basic monitoring, SpeedFan allows advanced users to manually or automatically adjust fan speeds based on component temperatures to reduce noise and prevent overheating. Although development has largely stalled for modern hardware, it remains a recognized tool for legacy systems and custom fan curves.
