PC Idle & Fan Noise Diagnoser for Efficient Background Operation

Many PC users experience unwanted CPU activity, heat, and fan noise when their computer is supposed to be idle or in a low-power state, especially when the monitor is off. This SaaS solution would be a desktop application that monitors system processes, power states, and component usage (CPU, GPU, storage) to identify the specific applications or background tasks preventing true idle. It would provide actionable insights, historical data, and recommendations for optimizing power consumption and reducing noise during passive use. This fills a niche for users who want quiet, efficient PCs even when not actively using them, but struggle to pinpoint the cause of unnecessary activity.
