all face the problem of heating of the computer.Even with its simple basic elements have a temperature of 50-60 ° C, and under load the temperature even higher.Traditionally, the cooling of heating elements produced by fans.But not always one staff member is sufficient.To reduce the overall temperature in the system unit can be put an additional fan for the computer.Many shells are from two to four places provided for their installation.
Choosing the right fan for the computer rather difficult - a lot like a really good copies and outright fakes or used coolers.There are several criteria to help you decide:
- Note the material of the body and wings.It should be of medium hardness.Too rigid sensitive to physical shock, is too soft will not be able to operate at temperatures above 45 ° C.If you find a fan for a computer in an aluminum case, you are lucky, most likely it is a quality product.Grab and run.
- If you decide to buy a fan with ball bearings, keep in mind that the weight to be significant.Even small model 60x60 always heavy.
- Inspect the surface of the blades.In good producers, they are smooth, almost polished.
- Check conclusions tachometer, temperature control and emergency stop.If not, before you cheap, perhaps, bad model.Also check the markings on the power cord - good company always try to describe all the details on the cheapest option so you will not find markings.
- When purchasing be sure to ask to turn the fan for the computer and hold it in your hands.If the level of noise and vibration is strong, should look further.
Quite often there is a question about what the computer case fan for better - on ball bearings or sliding.This depends on the ambient conditions.If the device will be used in high or low humidity, it is necessary to choose a plain bearing - it is less responsive to this option.With the temperature is different.If it is near 50-70oS (it is this temperature in the housing running computer), it is best to choose bearings - share their work in such conditions, is 3-4 times higher.One "but" - they are much more noisy, and there is such a fan for a computer is much more expensive.So, you have two options:
- buy Drogo instance on ball bearings with a long operating life, but with a fairly high level of noise;
- buy a fan for computer plain, but after six months or a year of change (begin to malfunction).
Which option suits you best, and the choose.And again before proceeding to the selection of the fan, carefully read the PC case.Open it up and find a place designed for the installation of additional cooling elements, determine where it will be put, determine the size of the desired model.The best one!
