Free Windows monitor for temperatures, fan speeds and voltages
SpeedFan report card
Good · out of 4.0 · graded Nov 13, 2026
Best for reading fan and temperature chips on older Windows PCs
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.
Who SpeedFan is for
- Fits if your PC is older and has a monitor chip it recognises
- Works for people who want disk health and temperatures in one window
Who SpeedFan is not for
- Skip it if your PC is new, as the page shows 4.52 with a copyright of 2000 to 2020
- Not for you if you run Windows 11, which the page does not mention
- Too light for fans it cannot see: control works only with supported chips
- Watch out: nothing on the page shows recent updates, so support for new hardware may be limited
Why SpeedFan gets a 2.6

- CFeaturesSensor readings, fan control, disk health and RAID support. Fan control works only with monitor chips it supports, and the 2020 copyright suggests newer hardware may be missing.
- CEase of useNo store rating is on record. Fan control means matching chips and setting speeds by hand.
- DPlatforms and integrationsWindows only, from Windows 9x through Windows 10 and Server 2012. Windows 11 is not mentioned.

Keep SpeedFan, or make your own?
Keep it
SpeedFan is free, so making your own would save you nothing.
And it is not the kind of software a weekend replaces.
What you could not
- Connections to other products, each kept working as those products change.
- Readings from inside the operating system.
- A real app for Windows. Something home-made would be a web page.
What this rests on. SpeedFan’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
