My cooler master masterbox lite 5 front fans are so loud and they are connected to the motherboard yet they don't show up in bois setting

Look for some software from Cooler Master that lets you slow them down a bit.

Also check if they are PWM fans. If yes, you can set it to silent given that your motherboard supports this feature.

However, as a general rule of thumb, pre-installed fans aren't the greatest. If you really want the good stuff. BeQuiet have some good quiet fans and Noctua as well (even Noctua's don't look as wuiet on paper, bevause they work so well, they don't need to run at full speed to achieve same results and therefore cam be as quiet as the BeQuiet Silent series fans).
