same problem here no sensor from Motherboard MSI MAG B550 TORPEDO for AMD CPU

Which version is this ? MemoryGroup line 131 + enumerator exception seems like an old version.

V242 the lastes

Has it ever worked since V238 and ++ ? ( since the driver change )

[GuiLL31]

can't tell, I think i was few version late but i don't remember. if there is a log that says the upgrade path I can have a look

[Rem0o]

Basically https://github.com/LibreHardwareMonitor/LibreHardwareMonitor got some radical changes due to being forced to change driver. Said new driver was jammed in there to replace all previous calls but obviously every single motherboard wasn't tested with this new implementation and there are quite a few backtracks when it comes to compatibility and bugs.

I used the new installation method with Pawn, it's been working perfectly ever since, but I think a couple of days ago there was a Windows update that broke everything.

[Aurelio-AVB]

I am experiencing something similar, worked well with v241. Installing v242 results in a lot of missing sensors.

shall we open an issue on their github page ?

[GuiLL31]

rolled back to v237 and all sensors here, just an issue with the pump speed doing back and forth (I guess conflicts somewhere).

so staying in v242 with no real cpu temp monitoing :(

[GuiLL31]

i've performed the following test :

• official release of librehardwaremonitor (472) : no issue all sensor OK
• download latest build from master : sensors KO

hope those issues will be fixed soon in the librehardwaremonitorlib so that controlFan can benefit from it

[GuiLL31]

@eaz-x are you a faceit user? if yes, the problem may certainly comes from faceit anti cheat ==> https://www.reddit.com/r/FACEITcom/comments/1nke0dn/faceit_force_me_to_use_winring0/

i've uninstall faceit AC & pawnIO, reinstall pawnio and fancontrolv242 works perfectly again :)

[eaz-x]

You're right. I installed Faceit's anti-cheat program 3 days ago, and it's been since then that the program started to fail. Damn.

The app is not detecting CPU fans. It only shows GPU fans, atm :/

Just countered exactly the same problem. Things went wrong since updated to V242, and reinstalling (even reinstalling the old version) didn't work
