How to check the fan speed of the iMac and the temperature of the CPU, is there a tool that only com

Master Lu and the like can check it out.

MacBook uses "System Assistant Mac Version" to see the CPU temperature method steps are as follows:

Tools required: Macbook, System Assistant Mac version.

1. First of all, on the App Store** System Assistant Mac version and install it, and then click on the number in the top circle to see the graphical CPU temperature, capacity and so on.

<>3. In the preferences, check the CPU temperature and boot startup.

4. After setting, you can see the temperature of your Mac CPU and the speed of the fan every time you turn it on.

Since Mac computers do not have BIOS, which is based on the underlying hardware software, it is impossible to directly see the CPU temperature and fan speed. However, the heat of the Mac is noticeably felt when you touch the keyboard. So how do you adjust the fan temperature to make your MacBookPro run normally?

Method steps

Click on the yellow arrow then click on Preferences.

In the preferences, check the CPU temperature here and there, as well as the boot startup. Then you can see it in the status bar after turning it on.

Set it to see the temperature of your Mac CPU and the fan speed status every time you turn it on.

Install the software in the diagram and open it. The default is English, we need to set Chinese first.

Click on the small fan icon in the status bar and select Show main window. Here is the Chinese status, because I have changed the language, in short, choose the first one.

Once you're in the main window, click Settings in the red circle in the bottom right corner. Select Chinese. OK to change to Chinese.

Once <> set the Chinese, click Auto there to set the CPU fan speed.

The speed of the fan can be changed by dragging the lever, and the CPU temperature will be lowered after confirmation. The ideal temperature for a Mac CPU is 30 to 40, and 60 to 70 for running large games. It's best not to run more than 80 virtual machines.

Generally, adjusting the fan speed depends on your temperature. Of course, the faster the fan speed, the lower the temperature, but it will reduce the fan life appropriately. Generally speaking, it is best to set between 2300 and 3000, and it is too bad to set it higher.

It is recommended to "Master Lu software to check the hardware temperature".

However, if the computer cannot enter the system due to the high CPU temperature or hardware problems, and the third-party software cannot check the CPU temperature, we can also use the second method, as follows. Go to the BIOS to check the hardware temperature (the old version and the new version).

The temperature of the CPU is more or less normal

Under normal circumstances, according to Master Lu's tips, the maximum temperature of the CPU should not exceed 85 degrees, and it is best to control the temperature below 75 degrees to be considered safe. The temperature exceeds 80 degrees Celsius, which can easily cause the computer to crash or automatically shut down, etc., which belongs to the poor heat dissipation of the computer. The problem that causes the high temperature of the computer is generally the problem of heat dissipation, for example, the temperature of the CPU of a laptop computer is significantly higher than that of a desktop computer.

Mainly because the notebook is affected by its small size. Let's briefly introduce what factors are generally related to the high CPU temperature of the computer

One: ambient temperature

The CPU temperature has a lot to do with the ambient temperature, and it will be a little higher in the summer. Generally, the temperature of the CPU is within 50° when idle, within 65° when it is busy, and within 75° when working at full speed, so we recommend that the ambient temperature is too high in summer, and the computer should not be left on for a long time, so as not to affect the life of the CPU; In winter, due to the low ambient temperature, we will find that the temperature of the CPU is generally controlled at about 30 degrees. If the CPU temperature is too high, it will cause phenomena such as reboot or blue screen of death.

2. CPU fan quality and host environment

Three: Overclocking

If the computer needs to be overclocked, it needs to increase the working voltage of the CPU, and if the working voltage increases, it will definitely cause the power consumption to increase, and the heat generation will naturally increase, once the heat generation and heat dissipation tend to be balanced, the temperature will no longer rise. The heat generation is determined by the power of the CPU, which in turn is proportional to the voltage, so to control the temperature well, you need to control the core voltage of the CPU. However, if the voltage is too low, it will be unstable, especially when the overclocking amplitude is large.

Many times the CPU temperature does not reach the critical value at all, and the system restarts with a blue screen, and then the culprit that affects the stability of the system is not the temperature but the voltage. Therefore, it is very important to set the voltage to the limit when overclocking, set it high, the radiator can't hold it, and if it is set low, the CPU can't stand it, so it is generally not recommended to use overclocking technology.

Go to Weifeng.com, search for the software [checkup], and double-click to install it. It's the best Mac system software I've ever seen, and it also includes program processes, capacity, fan speed, and more.

Use "Master Lu software to check the hardware temperature".

Use Method 2 when the computer cannot enter the system due to high CPU temperature or hardware problems, and the third-party software cannot check the CPU temperature.

Step 2: Go to BOIS to check the CPU temperature.

If the computer crashes and cannot enter the system, or the blue screen of the computer system will definitely not be viewed by the software, but you can enter the power in the computer BIOS settings to check the health and temperature of the computer hardware.

The method is as follows: Start the computer -- enter BOIS (most computers can enter BOIS by pressing the DEL key all the time after booting up, if not, you can refer to your motherboard reference book) -- select the Power menu --- PC Health to check the current processor and other hardware temperatures, as shown below:

The temperature measurement methods of various motherboards are different, and even the motherboard of the same brand and model will also cause a large difference in the measured temperature due to the difference in the distance between the temperature probe and the CPU.

I recommend Intel's official and a lot of detailed data about the CPU.
