The causes of noise in the processor
During operation of the computer, all his e-mechanisms gradually warm. And some components get warm very significantly. For example, during the game there is a strong load on the processor and graphics card. But even in normal the computer is idle the temperature of the individual components is kept at 50-60oC above zero.
But if the system unit or laptop very rarely cleaned from dust, heat and the main parts will happen even faster. Overheating leads to constant computer freezes, and the fans, trying to solve this problem, work at high speed. And this leads to the irritating noise. Constant overheating can result in accidental breakage of one or more parts of equipment.
Therefore, to get rid of the constant noise, it is necessary to reduce the speed of the cooler. And the reasons that lead to the appearance of noise, only three. First, overheating of computer components. This is especially true of laptops, especially in the summer when the room temperature is often above normal. To reduce the number of revolutions of the cooler, need to clean your computer or laptop, or replace the thermal grease on the processor.
The second reason is poorly lubricated or just plain old cooler. For best performance it should be cleaned and lubricated.
And the third reason – the new fan was selected with more than you need speed. In this case, you just need to reduce his momentum.
Setting the operating mode of the cooler through the BIOS
To change the operating mode of the cooler through the BIOS. To get started, you need to restart the computer and as soon as I start booting, repeatedly press the Delete button. Opens the main menu of the BIOS, where you should go to the Power section. Next you need to select a line in the Hardware Monitor, and then change the value in the row of the CPU Q-Fan Control and Chassis Q-Fan Control to Enabled (i.e., enable).
As a result of these actions there will appear a new line Profile CPU Fan and Chassis Fan Profile. They have three different modes: productive (Perfomans), quiet (Silent) and the optimum between performance and noise (Optimal). After selecting the desired mode you have to press the F10 button to apply the changed settings. After these simple manipulations the cooler will produce much less noise during the operation of the computer or laptop.
