Tips on maintaining computer hardware and software: how to work with MS office, reinstalling Windows 7, 8, XP, how to make a boot ISO image, BIOS settings, wifi password recovery, cleaning and maintenance of computer lubrication fins and much more ...
The life of your computer most - probably depends on the fans. At least two, in almost all current computers - a little Faster CPU cooler and bigger and slower power. Many computers have 80 mm a second iupac fan mounted in the front of the box to help with the air flow.
Motorchetata in modern computer fans are brushless units based computing standards are good. But the axis on which the fan is spinning, sitting in camp and bearing wear.
The most commonly used and inexpensive type of fan bearings is a "sleeve". There is a simple design: steel shaft just sits in a solid bushing. Typically iupac the sleeve is made of sintered (burnt) bronze, which is a porous iupac metal in which they are sprayed iupac lubricants in the factory. When bearing grease over, starts iupac wear and heard the characteristic hum. Wear will deteriorate more and more buzz -shumno and louder, and the fan -will slower and slower until they stop completely.
This process can take weeks for larger iupac and slower fans, but it can happen much faster for smaller iupac and high ventilatorcheta. Refusal CPU cooler (CPU fan), probably will not leave you with a dead CPU, but will make your computer unusable practical until replaced (overheating CPU will trigger protection that will shut your computer also when turning typical iupac silent as biiypvane).
Here's how the ball bearing on the inside - a ring of steel balls in the space between the outer and inner rings of metal. The balls roll between the rings, which allows them to rotate freely.
Ball bearings remain a better option than the cheap bearings bushings; iupac some high-tech iupac sliding bearings that exist now may outlive ball bearings, but most fans of computers using cheapest option. When ball bearings at - eventually spoil, they are only for the trash.
If you find that the camps deteriorate before it gets too bad, however, you can extend the life of the fan much more with a few drops of oil. If you lubricate the bearing before you feel any symptoms were worsening, the fan can live many times more than what is guaranteed by the manufacturer.
Most ATX power supply (ATX Power Supply Units [PSUs]), iupac including the one pictured, have a fan installed so that you can see the sticker by removing the fuse for the fingers. Unscrew the four screws holding the cover (they also attach the fan, but it will not have much room to move, even without them) and you have access to the sticker from the fan without removing the cover supply.
Now carefully peel off the sticker. If damaged, do not panic, you can just replace it with a piece of tape. Small ventilatorcheta are often sealed with a sticker and nothing but big fans usually have a round plastic cap under the sticker. This fan has a rubber cap that is removed quite easily.
Do not use WD -40 or similar products. WD -40 have greater penetration displace water better, and loose rust, but it's disgusting grease. T It is the mainly kerosene and oil that remains after the kerosene evaporates, is more than enough to stop the gate from the hinges creak, but will not last long in the fan bearings.
Resist the temptation to try to fill the camp completely with oil. If the fan is installed vertically, excess oil will run out quickly. Even when the fan is installed horizontally with space for up lubrication, the centrifugal force of the fan rotation in most of the oil will run out.
If you want to fill the recess with oil well leave the fan on sitting for some time so that the oil can penetrate iupac the camp. But soak up excess with something before putting the sticker back (if you do not, the sticker will not stick, and should be clean place to stick).
This small fan in the network switch (network switch), iupac appearance does not seem like something strange. But it actually iupac works 5 V voltage rather than the usual 12 volts, so it will be difficult to replace.
