Where SpeedFan keeps configs on Windows, classic fan control layout. Full paths are listed below. More below.
Last updated
SpeedFan is old school portable fan control. Curves, labels, and offsets live in cfg files beside the executable. There is no account cloud to sign into.
That flat design suits single bench PCs. Moves need manual folder copies. Exact cfg names are stable across late releases. For keeps, copy the whole folder after tuning fans. Screenshots of advanced tabs help more than remembered paths when rebuilding on new boards. When in doubt, verify paths inside the app before trusting a remembered folder.
Where SpeedFan stores this, by platform
C:\SpeedFan (cfg files beside exe, no cloud)
Curves live in cfg files beside the exe with no cloud account. Copy the whole folder for moves. Reinstalls wipe curves without a copy.
Frequently asked questions
How do I move SpeedFan configs to a new PC?
Copy the SpeedFan folder with its cfg files to the new PC over USB. Fan curves and labels live privately in those files. Reinstalls mean fresh folders, so old curves vanish unless copied. Screenshot fan tabs before wiping for reference.
Does SpeedFan sync online?
No. SpeedFan reads sensors live and shows them without uploading. The PC holds the exe plus config. Values survive only as screenshots or notes. Reinstalls reset curves, so export by copying the folder itself.
