Which one is for you

Pick Core Temp if

  • Fits if you want a small readout of CPU temperature on a Windows PC
  • Works for people who add plug-ins to show readings elsewhere

Look elsewhere if

  • Not for you if you want to set fan speeds, since it only reports
  • Skip it if your PC is Arm based or runs Mac or Linux, as it covers x86 Windows only
  • Too light for whole-system monitoring, which covers drives and graphics too
  • Pricey if you run a company: one commercial license per physical machine, ordered by email

Pick SpeedFan if

  • 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

Look elsewhere if

  • 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

CSensor 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 use
BNo store rating is on record, but it is a small program you install and start using with nothing to set up.

How this page was made

  • The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
  • The grades are our own, from each tool’s review or report card. The GPA is their average.
  • Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
  • The differences and the answers to the questions are worked out from those listings.
