Make Computer Quieter

Here is the video card in the circuit cooler series resistance .

He's a piece of paper in the background.

And power consumption is shown on the reverse side. To see have to remove the cooling system.

Of course , open circuit must be isolated . For photos of the insulation was removed .

Table derating factors when added to the series resistance of the circuit :

Not difficult to see that the quadratic dependence . Who familiar with school physics well , not because I'm the one without the calculations would guess about the nature of addiction.

Resistivity index-the ratio of the total resistance of the circuit ( with series resistor) to resist the cooler , that is, when added to the chain of resistance equal to the resistance of the cooler , this value will be equal to 2, and the addition of half a resistance of the cooler it will be 1.5 .

Derating factor-the ratio of the source of power dissipation fan to fan power dissipation in a circuit with series resistance . Shows how many times the consumption is reduced fan power .

File with the calculations can take here.

Cleaning and replacing the fan

Fans of old age can jam or start a buzz or rattle . In such a case, you can make out the faulty mechanism , removing the impeller , clean the axle hub , lubricate and assemble. It helps, but not for long. This way I can recommend only as a temporary measure before buying a new one. Not a single fan has not worked well for a long time , after such recovery efficiency . Certainly can not hurt , and just wipe the dust from the fan .

Over the purchase of new ones.

Very little is better not to take, if it is possible to take more (unless, of course, it fits on the target site ) , just pay attention to the level of noise generated . By reducing the noise worse heat , so do not hurt to add one or two fans to the computer to draw warm air from the interior (they also can be quiet if required ) .
