电脑开机时风扇声音大如何解决

电脑开机时风扇声音大如何解决 1,共振; 2,cpu风扇; 3,电源风扇; 4,电源功率; 5,电压不稳定. 从这几方面进行解决: 1、拆开机箱，清扫所有灰尘(特别是北方地区)，最好用废旧毛笔清扫，伴随着吸尘器能够较干净的清理。 2、卸下CPU风扇通道固定螺丝，小心打开CPU散热片，你会发现CPU与散热片间隙中的硅酯早已干燥(与CPU功率大有很大关系)，用稍湿润的干净补清理干净干燥的硅酯，晾干。 3、有条件的可以用高级硅酯补上，没有条件的用以下方法:将购买来的或要白色普通硅酯少许挤出到玻璃片上，用碳素铅笔边在玻璃上磨边搅拌，直到白色的硅酯变成浅灰色并变得稍稠，用刀片在干净的CPU上涂上薄薄的一层，即可安装散热片，切记不要来回移动散热片，使散热片与CPU良好的接触。,这种方法制作的硅酯与英特尔专用硅酯经测试差别不大，具有良好的导热性且不易干燥。 4、小心插下大风扇，将风扇中央带有商标的圆形不干胶小心掀开，可以看到中央的中心轴暴露出来，用凡士林(很便宜，药店都有卖)仔细涂满，仔细封上 带有商标的圆形不干胶即可。,原理:凡士林大多用来涂抹手，防止冬季干燥皮肤干裂的，它有personal safety and safety equipment. 5.1.1.6 construction overall arrangement of instruments (see the following figure) ... 5.1.3.1.1 cabinets, Terminal cabinets, enclosures, UPS battery cabinet base hot-rolled angle steel, hot-rolled angle iron and steel production, the support base as a whole should be kept straight, the weld size overall dimensions meet the requirements should be the principle, Stent positioning and embedded parts after welding in prison. 5.1.3.1.2 bracket mounting holes required on arrival at the scene, cabinet base hole dimension processing.
