I know that I can use it to adjust fan curves in Windows, but this can also be done in BIOS. This program causes conflicts with HWInfo, which is used to monitor CPU and RAM usage in the RivaTuner OSD while gaming and on the system tray, and will not work with Bitdefender Total Security. I tried BDTS free trial and with AI Suite 3 installed, it messed up web browsing. And I would rather have BDTS than BD free and want to use HWInfo. Is AI Suite 3 really necessary?
