iStarUSA DIY series kits are designed to reduce noises caused by operating hardware. The DIY-KM319 PC anti-vibration kit reduces vibration and noise produced between the active and passive components. The package includes rubber stand-off for PC and compatible to notebook. HDD and fan rubber screws reduce the vibration of hard drive and system fan operation. Fan washer foam close the gap between case and fan, this improves the efficiency of the fan by reducing feedback airflow and therefore reduces air pressure losses.
