What is the problem? Nowadays, computers almost ceased to cause noise problems, unless they are located in a room where it is quiet.
This is different for servers, which are often placed in a server rack, causing a lot of nuisance because of the fans. The nuisance of this noise problem mainly consists of airborne noise, but in light server racks contact noise from the hard disks and fans can also cause problems.
If the computer or server is placed on a wooden floor, there is usually contact noise. In this case resonance from the equipment can be clearly noticed as a hum. Placing the equipment on pieces of Regufoam solves also this problem.
Insulating PC housing A PC housing is usually made of a thin sheet material such as steel or aluminum. These materials are too light to stop the noise and vibrations coming from hard disks or fans. By equipping all surfaces of the PC housing with anti-drumming mats, for example STP Black Silver, the housing becomes heavier and the insulation value increases. Subsequently, apply absorption material on top of the anti-drumming to reduce airborne noise. We recommend Flamex Basic because of its properties, such as fire safety, low thickness and excellent absorption values.
Isolating server racks ICT furniture (server racks) often does not have enough space inside to fit absorption or anti-drumming materials. Server racks are usually constructed from thin sheet steel walls containing space for computer and server equipment. These 'can' walls resonate easily and allow sound to pass through. Equip this sheet material with anti-drumming such as Vibraflex BS 50 for large projects or STP Black Silver for small jobs. Behind the serverrack you add Flamex Basic, at least 40 mm thick, in order for airborne noise to be absorbed.
If, for instance, it is possible to convert a broom closet into a server room, this can also be highly effective. Install adequate ventilation, a door that closes off well and equip the walls with absorption material.
