hi. i have a alienware 17 r2 2015. i heard using hwinfo64 i can change fan speed manual and set custom speed. what i know that before the latest update there are only 3 options for fanspeeed. now the latest version we can have more fan speed choice/options. is that right? also for settings turning on IDE/sata drive scan must be put on safe mode and tick low-level pci access,tpm check,ec support,and evaluate acpi methods. with them as you settings will it not cause anymore distorted sound or cause lag to the laptop? help me on putting on the right settings please that would not cause problems and i can monitor the fan speed if possible and change fan speed with more options. thanks
