Which kind of fan are you referring to? is it the case fan/chassis fan
Depending on the quality of the case fan, some produce more noise than others. Overtime these fans degrade so it is a good idea to replace them with a new one with the right dimensions in order for it to fit in your case. I'd also advise not to control anything using the speed fan program unless you know what you are doing. If you unplug the case fan, then (assuming you only have one in your case) there will be no fan to deal with the accumulated heat inside it. Internal components begin to pile up heat hence, would cause damage to hardware over time and depending on your BIOS settings, will force your computer to shut down once it reaches a certain high temperature level.
