Who does not want a quiet computer? Noise reduction in computers in recent years increasingly become the focus of many buyers. And it is well to inform themselves before purchasing. Get quiet a loud instrument, can be arduous and ultimately more expensive than buying the same to look for low-noise components. So I would like to outline some general considerations regarding the new purchase.
I want to preface that I have a water cooling is not necessarily suitable for holding to operate a computer quietly. It is rather something for overclockers. Radiators are usually cooled with fans and then I need to convey that in addition to the warm air from the computer. And a low-noise pump must also be found yet.
The belief that insulation batts can turn a noisy computer is a silent, a misconception. You can exceed the icing on the "i" be. Airborne, they can reduce up to a maximum of 0.4 sone. They also have a downside: not only hinder you insulate sound, they also heat to the outside. So they should be used sparingly, only to the (potential low) residual noise to reduce. Sound is always avoided insulate against noise!
The tips here are based less on experts who have enough experience to build a quiet computer. But the user would like to have a quiet PC and have little knowledge of the required components, may be here to get an idea or two.
