Sometimes, when we open a large game or open a lot of programs, we will hear the ' buzz ' in the chassis, don't be surprised, this is the CPU fan working.
When the CPU temperature rises, the system will dynamically obtain the temperature of the CPU, when the temperature is too high, the fan will automatically speed up the rotation, cooling, and usually keep the lower speed, so not only to save electricity,
Fan blade "Eccentric" is the main cause of noise. The quality of the fan, the center of its fan blades on the axis, operation is very smooth, the noise is very small, and the inferior fan, often there is a certain deviation, the center of gravity is not in the axis of the "eccentric", such a
2. process chain and process fan(1) Create process Chain ① Process Chain : That is, the parent process creates a child process, and the child process that is created creates the child process that belongs to itself again, so that it loops down as shown in turn. ② key implementations: determines that if the parent process exits , the parent process will only create a child process. if it is a child process, continue to create the next process and th
Tag: no 51ctoIn the game development often need to calculate the fan-shaped field of view or hit range.In fact, this is divided into two parts,The first part is within the fan range (i.e. regardless of the angle, in fact the circle range)The second part is in the fan angle rangeThe first part is very simple, vector3.distance (A, b); calculating distancesHere is t
In fact, this is not familiar with the circuit of the user may not know the internal structure of the chassis, generally bought chassis fan, built-in 3PIN interface, but will bring a large 4PIN transfer wiring. Computer motherboard is a Sysfan interface, generally there are two interfaces are 3PIN interface, if your chassis fan is also 3PIN interface can be directly connected.
If it is a large 4PIN, it can
1. Computer power supply fan turn and stop
Should be power protection, unplug the power from the motherboard, hard disk, optical drive, video card, and so on the internal components of the connection between, and then to the power supply, with a wire will be the largest power source of a large line of the plug in the Green Line and black line short-circuit, if the power supply is working properly, the focus of the chassis to check the components, The
The most affordable is to repair themselves, the material is very simple, as long as a small piece can aluminum skin and a little butter.
Cause of
May be the video card fan due to the lack of oil, bearing hole is worn--fan shaft and bearing gap between the too large. Fan in the rotation of the axial movement, and the rotation plane of the blade is also shakin

1. Open Photoshop and create a transparent background document with a width of 10cm, 5cm, and 72ppi resolution.
2. Use the rounded Rectangle tool inside the shape tool (paint only, do not draw path mode, fillet radius 15 or so), and draw a blue-purple rounded rectangle about 9cm long, as shown in Figure 1.
Figure 1 Fillet Rectangle
3. Press "Ctrl+t" to pull out the deformation tool, move its deformation center to
1, remove the fan from the chassis, you will find a sticker sticker on the back
2, use tweezers to take down the post. Some fans have stickers on both sides, I do not know which side is the sealing effect, then the two sides are open to see it.
3, uncovered after the bearing is found in which, carefully again see, will find a small stop ring. Many friends may be in this step, they will be injected into the f
Summer arrived, the weather is unusually hot, in no air-conditioning, no fan room inside, only a fan accompany, noon to eat a little sleepy to sleep, shake the fan lying on the bed, shake the fan of course to cool, so slowly feel the eyelids are fighting, this time the whole body do not want to move, So hand holding a
The user's UCS Manager, found chassis 2 6th slot fan Alarm, led does not light, the slot fan and other normal slot fan interchange, the fan is working properly, but the original good fan inserted in the 6th slot, still alarm, LED does not light. The initial judgment should b
This article mainly share desktop computer fan noise and how to eliminate it? Usually the computer host heat dissipation, as the computer's most important tool fan, but also because of the high frequency of use, resulting in more noise. In the face of this situation, do you want to eliminate the noise? Perhaps, you would say that the direct replacement of the fan
Some time ago, the installer installed Windows 2003 on my Compaq x1000 notebook. The fan keeps turning and cannot be understood. The CPU usage is only 1%. It was found that the high CPU usage of the Indexing Service and. NET 2.0 optimization services have also stopped. However, the CPU fan is still switching. Google cannot find any solutions. Reinstall Windows XP. I found that the
Temperature for the computer is the first killer, the computer's heat dissipation is absolutely the most important, and the heat dissipation of the CPU is of particular importance, then how the CPU to choose a good radiator (cooling fan)?
CPU radiator is a necessary part of the computer, but also the performance of the system plays a very crucial role, good radiator not only to ensure the normal work of the computer, greatly reduce the blue screen, t
Believe that many users have encountered the power switch, the fan works but the computer does not start, for the system after the boot of a small number of problems, most users can also be resolved, but encountered even on the boot can not start the problem, most users do not know where to start to solve. In fact, the computer can not start the failure of the normal troubleshooting is not difficult, today small series on the
Perfect solution for t4x fan noise problems (hot issues) Latest Version v018 Chinese Version update !!!
This is an IBM fan control program developed by foreigners. It perfectly solves the problem of T43 fan revolution and can control the temperature and speed of Fan rotation. I have passed the T43 al9 test.Open and ed
The computer used for a long time, of course, there will be a small problem, such as fan noise, computer cards and other problems, the following rain forest wind explain the downfall of the computer fan loud reasons and Repair methods:
First, check the common causes of brain fan loud:
1, bearing lack of lubricating oil
Bearing for the
Failure phenomenon:
R510g7 appear similar to the alarm sound of ambulances, and alarm lights red light alarm, the boot will appear fan 2-1failure prompts, the system runs normally, observe fan speed normal, door-to-door replacement motherboard failure can not be excluded, the final judgement for fan failure. How do I locate the faulty
Failure phenomenon: A new configuration of the assembly machine, usually use everything normal. Only in the motherboard BIOS, the CPU fan speed is reported to be 0 rpm (Turn/min), while the actual fan operation is good.
Failure Analysis: Currently, the ATX architecture of motherboards basically support the fan speed monitoring function. This allows us to keep ab
