1) Install it using the Ubuntu installer after downloading the ISO for the release and flavour of Ubuntu you want, and making a LiveUSB to install from. If you wish to keep your existing Windows 10 with its special apps, you can do so; the installer lets you create a Dual Boot option where Windows 10 and Ubuntu are installed on their own partitions on your SSD. You won't be apple to run PredatorSense and Waves MaxxAudio in Ubuntu, but you can still use them when you boot from Windows.
If you have NVIDIA and/or WiFi issues, come back here and let us know in a separate question. Please make sure to include what you type in or selected and what error messages you got when you do. It would be very nice, when you say you read about problems, to have the web link back to what you read which concerns you.
2) Once installed, take a look at fan control packages such as Ubuntu smart fan and fan controlling daemon, among others. To replace Waves Maxaudio, there's Pulse Effects, Jack with CALF Plugins, and LSP, among others. It's Ubuntu, we have answers.
