How does the MacBook fan sound big?

How does the MacBook fan sound? A lot of friends who use MacBook notebooks will encounter a fan when the sound is loud. Some may be hardware problems, some may be software problems, or some of them belong to the normal situation. Below is a brief description of some of the factors that cause the MacBook fan to sound large, along with some caveats.

1, we use the MacBook notebook computer, the inside of the chip in the operation will generate a lot of heat. Inside the computer there will be a heat pipe absorption, such as the CPU, graphics chip generated by the thermal, and then the outlet end through the fan transfer of these heat discharged outside the fuselage.

2, my MacBook Pro notebook is in 2013, whether it is the office or open Windows virtual machine, there is no sound fan rotation. This means that when we are running some light applications, when the computer is running low, the fan only needs a slight turn or the heat can be emitted directly through the heat conduction tube.

3, if we are running some large-scale applications, such as the game, the CPU and graphics card usage will quickly rise, resulting in a lot of heat constantly generated, the system fans will be mad, so as to ensure that the heat discharged in a timely manner, to ensure the stable operation of the computer system. At this point you will find that the computer's fan sound is bigger, makes people feel very uncomfortable.

4, the picture below is I use a software used to detect the current MacBook notebook temperature, in the right panel of the software can see the current real-time temperature of each part of the computer, in the left window can see the current real-time fan speed.

5, next to do a demonstration, with CINEBENCH performance test software, first the MacBook CPU to perform operational testing.

6, then check the fan speed monitoring software, you can see the current fan speed has reached 1900 rpm, but at this time still do not hear the fan rotation sound.

7, next use CINEBENCH to test the performance of the graphics card, when the temperature of the chip is rapidly rising, the speed of the computer fan has also increased to 3000 rpm per minute.

8, then on the MacBook to play World of Warcraft 3D game, play not long, you can hear the fan crazy turn of The voice, at this time to see the software monitoring fan speed has reached 6000 revolutions per minute.

9, personal suggestions in the use of MacBook notebook to play games, if not with a separate graphics card, it is recommended in the game settings to lower the effect. This lets the game not card, but also can reduce the load of the video card.

So, when you hear the MacBook notebook fan sound big, it must be running some software with high load on the CPU and the graphics card at this time.
