RivaTuner doesn't detect my dedicated graphics chip (AMD 7470M) which seems to control the fans, so I can't force fan settings. SpeedFan is unable to display the RPM and has no effect, and my mainboard (SJV70 HR) is also unrecognized. It's an OEM machine where I don't have any BIOS options and I was unable to find a compatible unlocked BIOS I could flash.
So, is there a software solution for this? Not looking for general advice how to prevent overheating here, I just want my fans to run 100% all the time regardless of actual temperature, like they do on booting. Possible?
