Also not very loud, before and sometimes will ring, but before they are patted the chassis or boot, will stop after a while. But these days has been ringing MEIZHE (how angry I gave it to him to give to _). Just took the mainframe apart, found that the power is the problem, and removed, dust and oil, and then installed, boot... The result, TMD, is ringing...
You can not cure this problem, and directly change the power line, even if you add oil, soot, or for some time will ring, or you change the power supply fan can also, but the general situation is more troublesome
Remove the fan. Take out the rotating shaft, wipe it clean, add the oil, move it back and forth, and let the oil into each position of the rotating shaft. It is sure to solve the problem... What you are saying is that the fan or shaft of your mistake is not clean and refueling is incorrect.. Check carefully, you are sure that the power supply, you can not connect to the fan, then the power supply, boot test on the next. (pay attention to the power, or you'll have a short circuit with other metal.)
In the case of this noise, there will be nothing more than a CPU fan, a video card fan and a power fan. You can turn the fan rotates, gently press the fan according to stay, time to be fast, it is possible to detect which fan sound out (if you have any other installed fan check)
How much power for a new power supply or power supply if power is not to brand machine for Taiwan power supply noise to said machine does their personal brand to installed two computer power supply is eliminated in the company of the host on power than the new power supply (except those who buy brand new good too much power)
First, it is wrong to shoot the chassis; the hard disk is afraid of vibration..Next, the sound is big, the reason is many aspects, for example the fan is originally the sound quite big style, goes in the dust, cold weather and so on..If you want to fix it, add more lubricating oil and make sure the oil is not good.. Better get some solid old butter. Maintenance is not worth much.Or simply try to remove the fan and buy a new mute fan.The new power supply, and now most of the power is mute.
