After careful consideration I have decided to transfer all hardware review activities to a new domain. I purchased Hardwareasylum.com in 2012 and have been working hard to build a new and improved Ninjalane on that domain. If you are reading this you have reached one of the archived articles, news, projects and/or reviews that were left behind during the site migration.
Please update your bookmarks and be sure to visit the new and improved Ninjalane at Hardwareasylum.com
For instance hold a fan in your hand and spin the blades with your finger. You will feel a "buzz" or vibration in your hand as the motor's magnets fire and shut off, these vibrations are transferred into the case structure and can produce resonance noises such as humming or rattles. Hard drives also have moving parts that can add their own harmonics to the mix. One of the worst offenders has always been the optical drive as it spins up. Tackling these varying types of sounds requires a variety of different solutions and any silent case will have to handle them all.
