SpeedFan reads voltages, temperatures and fan speeds from hardware monitor chips and can change fan speeds, plus disk S.M.A.R.T. data. It is free, but the vendor's site shows version 4.52 with a 2020 copyright and no mention of Windows 11. - **Value for money: A.** Free to download and use, with a PayPal donation link. - **Free plan and trial: A.** The full program is free with no cap or trial clock. - **Features: C.** Sensor readings, fan control, disk health and RAID support.

And it is not the kind of software a weekend replaces. - You could not: Connections to other products, each kept working as those products change. - You could not: Readings from inside the operating system. - You could not: A real app for Windows. Something home-made would be a web page. A judgement by ToolGPA from this listing, by rules that are the same for every tool.
