What does the fan do on a computer?
A computer fan is any fan inside, or attached to, a computer case used for active cooling. Fans are used to draw cooler air into the case from the outside, expel warm air from inside and move air across a heat sink to cool a particular component.
Where are cooling fans typically used in a computer?
Fan cooling is often used to cool processors and graphics cards that consume significant amounts of electrical energy. In a computer, a typical heat-generating component may be manufactured with a flat surface.
How do case fans work?
The fans on the front of your PC's case are typically intake fans, drawing in the relatively cool air of the surrounding room to lower the temperature inside the case. Fans on the rear and of the case are usually exhaust fans, expelling the hot air warmed up by the components back into the room.
What is the fan in a computer called?
A heat sink and fan (HSF) is an active cooling solution used to cool down integrated circuits in computer systems, commonly the central processing unit (CPU). As the name suggests, it is composed of a passive cooling unit (the heat sink) and a fan.
Are Case Fans important?
Case fans are important in computers because electronic components generate a lot of heat. This heat increases the wear on those electronic components, causing them to have problems and possibly malfunction quicker than normal.
How many fans should you have in a PC?
Generally, you can have 2 case fans for intaking cool air. You can also have 2 case fans for exhausting the heat and replenish the cool air faster by removing the heat quicker. The exhaust case fans should be closer to the CPU to be more effective otherwise, you can just go for 2 case fans for intake.
How much air does a computer fan move?
A typical 120mm fan will transfer 20 - 80 cubic feet per minute if unobstructed - depending on the speed it runs at. Smaller fans will generally have a lower airflow rate. Your power supply will not usually specify the airflow rate, so assume around -20cfm. depending on the power rating and fan size.
How are PC fans powered?
The analog 3-pin and MOLEX connectors provide power to the fan to make it spin. Four-pin connectors are digitally controlled and let the system to alter fan speeds dynamically.
Which way do computer fans spin?
Locate the Directional Arrows
Inspect the outside rim of the fan and you should find the two arrows there. For example, you can have a left arrow that shows the airflow direction from the front of the fan to the back. There should also be a down arrow that shows the direction the blades rotate when powered on.
Does adding more fans to PC help?
But what about adding more? Adding an additional pair of intake and exhaust (for a total of four fans) will likely lower your temperatures anywhere from two to five degrees. That can be significant but anything beyond that and you are likely to see a diminished return in the range of one to two degrees, if that much.
How many fans are there in CPU?
Two fans are usually enough. Two more may see a max 2-3 degree drop in temperature. Benefit of any more fans is usually negligible. Keep in mind the GPU/CPU have their own fans which benefit from a well-designed airflow from the case fans.
Why are my computer fans so loud?
If you notice the computer fan running constantly and making an abnormal or loud noise, this might indicate that the computer is not running as efficiently as possible, and/or clogged air vents. It is important to keep dust from accumulating in your computer and ensure adequate ventilation to help reduce heat.
What is a Power fan?
"power fan" header is usually found on most mother boards. This fan header does not have any ability to change the speed of a fan connected to it. It supplies the full standard 12V to the fan at all times. You won't find any option in the BIOS or ASRock utility to adjust a fan's speed when connected to it.
Are fans necessary in a PC?
Yes, you need case fans. Preferably 2. Pull in cool air from outside, blow hot air out the back. Air and heat movement, not just blowing air around.
Is cooling fan necessary for PC?
You will need a fan on your CPU cooler and videocard, but for your current setup a case fan won't do much other than create extra noise. If the side covers are both on when using the computer, then yes a case fan would be required to prevent overheating.
