The loud sound is the because of the CD spinning at a high speed in your CD drive. Shouldn't be anything to worry about. Just a noisy CD drive.
Nero DriveSpeed allows you to change the read speed of your CD drive, to reduce noise. A free, older but fully working version can be downloaded here: http://www.cdspeed2000.com/download.html#nerodrivespeed
Unzip and run the 'DriveSpeed.exe' file. Insert the disc into the CD drive, then in the program, go to the options and 'detect' the compatible read speeds of the CD. You'll then be able to choose a lower speed. Note that you may need to wait a bit until the CD spins down to a slower RPM.
Since the program was originally part of a Nero suite, it won't be capable of running automatically if you check the 'Run at startup' setting in the program's options. Instead, you'll need to place the 'DriveSpeed.exe' file in a permanent directory and create a shortcut to that program in your 'Startup' folder of your start menu, in order to make it run automatically at startup. Otherwise, run the program manually each time you want to adjust the CD drive read speed.
