Any owner of a personal computer knows that without a cooler the operation of the system unit is impossible. To verify this, just put your hand to a computer that has worked for a couple of hours and feel how hot it is. And after all, this is with a working cooling system! It is terrible to think to what point the temperature of the processor could rise if it were not cooled by coolers for the computer.
We must not forget that the correct temperature is extremely important for the system unit - it must neither be supercooling nor overheating. And if the processor is unlikely to be able to cool down in room conditions, then overheating is very likely. To make sure of this, it’s enough to work longer in the summer heat on an old device with a not quite serviceable fan. Most likely, it simply can not withstand the load and turns off by itself.
But back to what the fan should be for the processor. Of course, the more powerful the device and the more they work on it, the more powerful the cooling system should be .
However, unfortunately, many coolers make 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 the reason for the 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 the name implies, a thermal sensor is a device that measures the temperature of the processor and provides information about it to the cooler. Thus, a fan with a temperature sensor may not work continuously, but to turn on at full strength only after the processor is heated to a certain temperature.
However, like any other, this device has both pros and cons. The pluses include a reduction in noise during operation, as well as an increase in the service life of the device by reducing its wear.
Of the minuses, the impossibility of adjusting the fan with a temperature sensor for a specific device is indicated - the processor temperature in it is set automatically, while it can have different optimal values for two system units of different companies.
Also, the inaccessibility of such devices is not considered an advantage - 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 independently. All that is needed is to make a thermal sensor and attach it to an existing fan.
The sensor is made absolutely simple. For him, only three elements are needed - a temperature sensor, power transistor and potentiometer. And, of course, a little time, perseverance and the ability to solder.
The assembly diagram of this sensor can be easily found on the Internet, and all the necessary details can be bought at any radio store. The resulting temperature sensor will have a considerable range of temperature control and the ability to turn off in the absence of load.
