Fan with a thermo-sensor own hands

Any owner of a personal computer knows that without a cooler the work of the system unit is impossible. 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 a CPU temperature could have risen if it had not been cooled by coolers for a computer.

We must not forget that the correct temperature is extremely important for the system unit - it should neither be supercooled nor overheated. And if overcooling in the room 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 should be the fan for the processor. 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 making too much 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 deterioration of the cooling mechanism.

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

As you can understand by name, the thermal sensor is 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 operate permanently, but can only be fully turned on after the processor has warmed to a certain temperature.

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

The disadvantages are the impossibility to adjust the fan with a temperature sensor for a specific device - the processor temperature in it is set automatically, while it can have different optimal values for the two system blocks of different companies.

Also not considered an advantage and inaccessibility of such devices - they can not be found in every city, let alone talking about 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 scheme of this sensor can be easily found on the Internet, 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.
