Fan with a thermo-sensor own hands

To any owner of a personal computerIt is known that the operation of the system unit is impossible without a cooler. To make sure of this, it is enough to put your hand to the computer that has worked for a couple of hours and to feel how hot it is. And this is with a working cooling system! It's scary to think how high the CPU temperature could have risen if it had not been cooled by coolers for the computer.

We must not forget that the right temperatureis extremely important for the system unit - it should neither be supercooled nor overheated. And if overcooling in the room conditions the processor is unlikely to be, then overheating is very likely. To make sure of this, it is enough to work longer in the summer heat on an old device with a not quite serviceable fan. Most likely, it just will not stand the load and turn itself off.

But back to what the CPU fan should be. Of course, the more powerful the device and the more it works on, the more powerful the cooling system should be.

However, unfortunately, many coolers are published tooa lot of noise, which is sometimes very annoying. The reason for this is their continuous work. By the way, it is not only a source of noise, but also a cause of rapid wear of the cooling mechanism.

The way out of this situation is extremely simple - you just need to purchase a fan with a temperature sensor. You can also make the sensor yourself and install it in an existing device.

As one can understand by name, the temperature sensoris a device that measures the temperature of the processor and supplies information about it to the cooler. Thus, a fan with a temperature sensor can not work permanently, but can only be fully turned on after the processor has been heated to a certain temperature.

However, like any other, this device has both pluses and minuses. The pluses include reduction of noise during operation, as well as an increase in the service life of the device due to the reduction of its wear.

Of the minuses, the impossibility is indicatedadjust the fan with a temperature sensor for a specific device - the CPU temperature in it is set automatically, while it can have different optimal values ​​for the two system units of different firms.

Also not considered an advantage andthe inaccessibility of such devices - they can not be found in every city, let alone individual stores. And the price of such a cooler can be indecently high.

That is why in most cases a fan with a temperature sensor is easier to do by yourself. All that is needed is to make a thermal sensor and attach it to an existing fan.

The sensor is made absolutely simple. It requires only three elements - a temperature sensor, a power transistor and a potentiometer. And, of course, a little time, perseverance and ability to solder.

The assembly circuit of this sensor can easily be found inInternet, and all the necessary details can be bought in any radio store. The received temperature sensor will have a considerable range of temperature control and the possibility of switching off when there is no load.
