Part 01 · Overview

Welcome

What it is, who it suits, its grades and the ten things to know first

2.6

GPA, above 69 of the 186 other desktop utilities we grade

SpeedFan is a free Windows program that reads hardware monitor chips for voltages, fan speeds and temperatures, and can change fan speeds based on those temperatures. It also reads S.M.A.R.T. data from hard disks. The vendor's site shows version 4.52 with a 2020 copyright.

To get you started, here are 8 things to know about SpeedFan, taken from its own pages and our grades.

Fan control means matching chips and setting speeds by hand.

The report card

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.

Value for moneyAFree to download and use, with a PayPal donation link.
Free plan and trialAThe full program is free with no cap or trial clock.
FeaturesCSensor 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.
Ease of useCNo store rating is on record. Fan control means matching chips and setting speeds by hand.
Platforms and integrationsDWindows only, from Windows 9x through Windows 10 and Server 2012. Windows 11 is not mentioned.
Grade point averageGood, out of 4.02.6

An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.

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 it 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

Good to know

Good for

  • Older Windows PCs with supported monitor chips
  • Combining sensor readouts with automatic fan speed changes
  • Checking hard disk temperature and SMART health

Worth knowing

  • Windows only; the page lists versions from Windows 9x through Windows 10 and Server 2012 and does not mention Windows 11.
  • The vendor's site shows 4.52 with a copyright of 2000-2020, so support for newer hardware may be limited.
  • Fan control works only with hardware monitor chips it supports.

Keep it, or make your own?

Whether this is something you could build for yourself with an AI app builder, and what you would give up.

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.
