Make Computer Quieter

Noise reduction unregulated coolers

We select the most noisy , turn off its connector (of course, on the computer is turned off ) , and will reduce the voltage to 5 or 7 volts. We find the positive wire , pull out of the socket and connect to +5 volts ( red wire to the terminal "yellow-black-black-red ", and any red coming out of the power supply) . Fan speeds will drop significantly and it will be virtually silent . If the speed is powered by the 5 volt appears too low , you can file a 7 volts to pull out of the positive and negative wires ( first and second) and connect the negative cable to the red fan from the power supply (+5 V) , and the positive to the yellow (+12 V) , the voltage will turn 7 volts ( 12-5 ) . But by the very young fans on the video cards , and other better not to use such a reduction of supply voltage , for cooling will be too small. In such a case it is better to hang the fan a little more (but do not connect to the power supply fan is more powerful graphics card if you do not believe that this will not lead to a deterioration of food chains cooler) .

Here is the connection to low voltage power supply ( 5V ) video card cooler :

In the photo above positive lead fan pulled out of the socket and connected to the + 5 volts from the power supply .

If you have , for example, the graphics card fan is a little noisy , it should be replaced by some larger and quieter , but still underestimate the turnover decrease the supply voltage ( if required). This cooling may not deteriorate. So it looks like:

Native fan removed and the radiator is hung on an extra cooler to reduce the speed of rotation was not necessary, and it is so quiet.

consider in more detail the process of replacing the video card cooler

The video card is a small and very quiet cooler began to rattle .
