When using computers, if not concerned about the problem of temperature, only know how to use and strive to wear and tear, deplete the power of their computers. Then in a short time your computer will no longer run well and stable.
For gaming computers, because they often have to work for a long time, and together with the use of graphics cards, it will generate a large amount of heat accumulated in the computer. If the computer does not have good airflow, it will lead to the computer always overheating. Therefore, the investment in case cooling fans will be effective in creating a cool airflow in the case.
To choose the right cooling fan for your computer, keep the following in mind:
For most systems, only one or two cooling fans is sufficient to ensure proper airflow. A fan is installed on the back of the chassis to push hot air out while a fan mounted on the front draws cool air in.
In addition, fans can also be mounted on the top or on the side if your case supports. Using more than two heatsink fans for a case is really overabundance for average gaming PCs, unless you’re doing this solely for aesthetic purposes.
Case fans are common in sizes usually 120mm, 140mm or 200mm, although other sizes are available as well.
But what is the best size of cooling fan? There is really no clear answer to this question, it can be said that the bigger the size, the better! This is because larger fans allow better airflow while not having to spin as fast as smaller fans, and also result in lower noise levels. As such, you should use the largest fan possible for your computer to ensure that your money is well spent.
Fan speed is calculated by the number of revolutions per minute – RPM. And the question of whether a high or low RPM is better depends entirely on your needs and interests.
Basically, a cooling fan with a low RPM will make less noise, the fan will run more smoothly, but the airflow will be less. As for high RPM, the opposite. However, to estimate the efficiency of a cooling fan, RPM is not a reliable factor, but depends on the size and design of the fan.
Radiator fans use different types of bearing based on their intended use and cost. Types of bearing commonly used in cooling fans include:
Sleeve bearing – This is the cheapest and most commonly used bearing among chassis fan types. However, the sleeve bearing does not work effectively at extremely high temperatures for long periods of time or at horizontal installation. So if you want to install a fan in the upper case of your case or your computer has to work in high ambient temperatures, this is not a reasonable choice.
Ball bearing – The most common type used in high-end chassis fans, Ball bearing is quieter, less noisy and more durable than sleeve bearing. Ball bearing can also be placed vertically or horizontally so you can attach it anywhere in the case. However, very few cooling fans use this bearing type due to the relatively high production cost.
Rifle bearing – A great combination of the two types of bearing above, rtifle bearing is not limited to the operating position as a sleeve bearing, and the ability to operate smoothly, with durability as a ball bearing
Hydraulic bearing – An improvement of sleeve bearing, hydraulic bearing is quieter and more durable thanks to its good self-lubricating fan.
Actually, the bearing type is not something you need to care too much, but hydraulic bearing is probably the best choice for cooling fans due to the advantages of long service life and quiet operation, reasonable price. But any other bearing will work fine. Just be aware that a cooling fan using a sleeve bearing can make a louder noise than other types due to wear on operation.
