subject: Chassis Chassis Noise Noise What To Teach You Tips [print this page] The chassis noise will affect the mood, both in learning is in the game. So, big noise of the chassis do? how to reduce enclosure noise? look at the chassis noise reduction tips below.
Posed by computer-generated noise is due to the resonance of the chassis, the culprit, mainly from:
1. hard drive, optical drive, internal vibrations of mechanical work;
2. the chassis, power supply, CPU, video card, and other parts of the heat sink fan and thus produce vibrations and sound.
We can see that the greatest impact is the cooling system, where fans will have sound. These cooling equipment is necessary, however, cannot be removed, only to start with reducing noise generated by the fan. Noise reduction is necessary, of course, because in addition to reducing the annoying sound, but also to a certain extent, extending the life of fan, hard drive and other accessories.
One of the chassis noise solution: the vibration reduction, noise reduction chassis
For the chassis,, which itself is one of many accessories in the quietest, but because of the noise of other accessories are installed into all distribution center. For example in a 5.25-inch and 3.5-inch Bay, due to the hard drive and the optical drive vibration resonance occurs at work, and side panels, front and rear plates and other parts will have resonance because fans. Most simple way is to resolve these resonance, tighten the mounting screw them.
If you still have more noise, can be part of the installation of accessory attachment to the chassis damping mat, shake the nail, and so on. Sound-absorbing cotton can also be laid in the chassis, so voices within the chassis is sound-absorbing cotton absorption, refraction will not occur, which will minimize the noise, usually 6cm of sound-absorbing cotton can decrease the 10~15 decibel level. 3M were once used for vehicle interior noise reduction in sound-absorbing cotton, so mute works very well. In the pavement when the sound-absorbing cotton, depending on the size on the inside of the chassis needs to be cropped, attention must not block the cooling vents.
Shake the nails instead of screws to noise reduction effect
Chassis panels covered with sound-absorbing cotton to stay out of the heat sink hole
Some users are afraid of computers too hot, multiple 8cm are installed in the chassis fan, temperature has not dropped the number of results, but noisy intolerable. This is because adding fans but to disrupt internal chassis air duct, affecting heat dissipation. Only need the front panel in the installation of a 12cm fan speed low and quiet, its higher thermal efficiency, reduce fan usage, thereby improving the chassis noise problems.
The chassis noise solution bis: dust, for power supply noise reduction
Power inlet is also dust the most vulnerable places, especially lower installed power, it directly from the bottom of the chassis into the wind, its easy smoking ash of trouble as you can imagine. When the fan blades and bearings dust accumulated over more than a, it could affect the rotation, thus not a small noise. So you want to get clean for the power supply on a regular basis, you can use the vacuum cleaner to clean out the dust. If power past the warranty period, can also be powered on, as fans bearing dust, oil, this can also significantly reduce the noise.
Thoroughly dust fan only power sweeping
Retrofitting shock pad or power. Due to a power supply installation and attachment to the chassis of the larger, can shock pad cut out a rectangular smaller pieces of side length is 4cm, affixed with double sided carpet tape, onto the latch brackets at the bottom of the power supply, so that you can avoid chassis resonance power supply fan caused noise.
On the power supply bracket, adding a very obvious shock pad
The chassis noise solution three: cooling, CPU, video noise reduction
CPU, video card is the key to computer accessories, matching radiator also more important, thus they also have one of the source of the noise. As far as the video, most of the high-end video cards currently on the market and match fan with intelligent temperature control feature, when the GPU temperature, fan speed will increase, resulting in noise increases.
The best approach is to strengthen the heatsink's thermal capacity, so fans at a low speed. Such as the processor, video card, and contact points of the heat sink grease in the use of long hardened or deterioration, resulting in lower heat transfer efficiency and high fan speeds, so you can periodically scrape out the old grease has hardened, then evenly coated with new grease, you can also swap the better heat transfer efficiency of gray grease.
Apply grease to CPU needs uniform formation
Of course you can also swap quiet heatsink for better heat dissipation, for example more than pure copper heat pipe, aluminum fins large, higher fans caliber, supporting temperature radiators, generally use big brand products on the right. @ Xiao
Edit view
Computer reported Lv Yuan: many users believe that the noise of the chassis, its internal cooling effect, the better, this is in fact not directly related, you think about if you are using low quality fan, at a time when its roar, nor received any good cooling effect. Therefore in addition to the selection of more quiet heatsink while, there is a need to address the noise problem from the source, sometimes need to be hands-on and small improvements can also make your chassis turns.
