Fan Control vs PowerISO
Side-by-side comparison of features, pricing, ratings, and alternatives.
Fan Control is a Windows utility by developer Remi Mercier (Rem0o) that gives PC builders granular control over CPU, GPU, case, and AIO pump fans. Instead of relying on motherboard BIOS curves, it reads temperatures from multiple hardware sources at once and lets you graph custom fan-speed responses per component. It uses the open-source LibreHardwareMonitor library for sensor data and supports a plugin system for extra hardware support (including some Dell laptops and HWiNFO integration). The app itself is closed-source but completely free, distributed via GitHub releases and package managers like Winget, Scoop, and Chocolatey.
PowerISO is a Windows‑based disk image utility that lets you create, edit, compress, encrypt and split ISO, BIN, and other image files. It also provides a virtual drive for mounting images and a reliable burner for CD/DVD/BD media. The software supports conversion between ISO and BIN/CUE formats, fast extraction of files, and password‑protected encryption, making it suitable for both casual home users and IT professionals who need precise control over disc images.
