SpeedFan

SpeedFanThe green version is a software that monitors computer fan speed and temperature and can display it in real timechip temperature, you can set different fan speeds according to the chip temperature. The latest version adds S.M.A.R.T. Technology monitors hard drives, and FSB Frequency adjustment function. SpeedFan has a simple interface and simple operation, and can monitor the current situation in real time.CPUoccupancy rate, and also has the function of FSB frequency adjustment. Use the SpeedFan tool to effectively monitor your computerfan speedand temperature, the chip temperature is displayed in real time, and different fan speeds can be set according to the chip temperature. Friends who like it, please come to Huajun Software Park to download and experience it.

speedfan FAQ:

      How does SpeedFan distinguish the fan power supply in the software?

Usually Fan1/Speed01 is for the CPU fan socket (CPU_FAN), Fan2/Speed02 is for the system fan socket (SYS_FAN), and Fan3/Speed03 is for the power fan socket (PWR_FAN).

      I set the speed to 60% in SpeedFan, but why does it go to 100% when I turn it on?

Regarding this problem, the main speed is the high value. What is the initial value of the Speedfan boot? Generally, the high value is 100%. Then when the boot is turned on, it will automatically adjust the speed from 100%according to the temperature of the CPU. If you want to fix the speed at 60%,

How to use speedfan:

1. Double-clickspeedfan(CPU fan speed control software) desktop shortcut, after opening the software, you can see the temperature data on your computer.

2. Click [Configuration] to open the configuration window, and select the [PWM 2 Mode] option. This option refers to the control of fan No. 2 (PWM 1, 3, 4, 5, and so on) and needs to be set below. Control method, here we need to select [Software Control], then [Memory].

​​ 3. Select speed 02 (everyone’s computer is different, some are 01, as long as the CPU fan speed).

​​ 4. The setting is SpeedFan’s automatic speed adjustment function, enabling automatic changes.

5. Then I found that the Fan2 speed changed very obviously. Since we are adjusting the speed of CPU fan Fan2, other Fan x data does not need to be displayed.

SpeedFan automatic adjustment method:

First, let’s briefly talk about the fan speed adjustment function of the motherboard and the fan interface on the motherboard. The fan speed adjustment function of the motherboard is divided into two types: PWM mode and DC mode. Motherboards of different brands and models adopt different modes, or they may support both modes. You have to go to the motherboard bios to see which mode is supported.

The so-called PWM mode means that the speed adjustment of the fan needs to be realized through a speed adjustment signal line. This kind of fan is a fan with a 4pin interface (the 4pin interface and the D-type port from the power supply are not the same thing). Generally speaking, 4-pin fans are difficult to buy on the market, and they are often only matched with original radiators. The most common one we have is the 3pin fan, which is plugged into the 3pin output port of the motherboard. Only motherboards that support DC speed adjustment mode can adjust the speed of the 3pin fan. However, most motherboards use PWM mode to adjust the speed of the CPU fan. The prerequisite for using SPEEDFAN to automatically adjust the CPU fan speed is that the motherboard supports either of the above two modes.

Although most motherboards have an automatic adjustment function for the CPU fan, the speed adjustment function of the motherboard is often unsatisfactory. For example, the noise is still very loud, or you want to be able to turn on the fan when playing games and turn off the fan when not playing games, etc. . At this time, you can use the software SPEEDFAN to control the CPU fan more personalizedly.

Precautions for using speedfan:

Temperatures 1, 2, and 3 in the above picture refer to the temperatures of the motherboard, CPU graphics card, and hard disk.

The temperature name should be clear:

System: translated as system, usually we can understand it as the internal temperature of the host or the temperature of the motherboard;

​ ​​CPU: It is the temperature of the CPU;

AUX: After searching on the Internet, it turns out that this is just an expansion test, which is equivalent to the PCI expansion slot on the motherboard and has no practical use.

HD0: The temperature of the hard disk. The following 0 represents the number of hard disks. If there are multiple hard disks, HDN will be displayed.

speedfan features

​​ 1. The fan speed can be changed according to the system temperature.

​ ​ 2. It can read hard disk temperature and SMART information, change FSB speed (soft overclocking, soft underclocking), and report the temperature and voltage of some nVidia graphics cards.

3. Each update of the software will add/improve support for hardware including large components such as CPUs and motherboards.
