What is the best fan configuration?
A optimal fan configuration would include intake fans on the front of the case. You'll also want to add the top exhaust fans. Including an exhaust fan on the rear of the case will round out an optimal setup.
Is higher fan airflow better?
A fan's airflow is measured by CFM or cubic feet per minute. CFM determines the amount of air that a fan can cycle through in one minute time limit. Generally speaking, the higher CFM the better.
How do I increase the airflow in my fan?
Turn on fans. When combined with open windows, they can work to increase natural air flow. Window fans are the most effective type. They are large, and because they work in combination with an open window, it combines the effects of both the open window and the fan.
What is the correct way to use a fan?
Place your fan so that it faces the opposite wall from where most of the activity takes place in your space. This approach will drive the air to the surface, where it will bounce off, mingling with the rest of the air and cooling the space.
What is the best air flow for PC?
Airflow in a PC case generally flows in two main directions: front-to-back and bottom-to-top. Front-to-back airflow is the standard, and almost every PC case on the market supports it.
How do I select fan speed?
Customers looking at fan speed should check the fans RPM (Rotations per minute of the blades). The standard 1200 mm (48) fan, runs at 300/350 RPM while the Hi-Speed fan runs at 380/390 RPM or so.
What is fan air flow?
A fanʼs airflow (Q) is the amount of air that it can displace per unit of time. It is expressed in m3/h (1.7 m3/h = 1 CFM). 1.2. Dynamic pressure (Pd) This is the force per unit of surface area produced by the movement of the air and it is exerted in the same direction as the direction of the airflow.
How do you optimize a fan?

What is a good fan speed for CPU?
1200 rpm is not particularly noisy. 2000 rpm might be tolerable. Even 6000 rpm might be possible, A 2000 rpm normal fan might be $12.
What is a good fan curve?
Add a few degrees Celsius to the max recorded temperature and use this as the second point on your CPU fan curve. After this point, you can start ramping up fan speeds under load situations. I prefer a linear increase from 45% at 65 degrees Celsius up to 90% at 90 degrees, but feel free to go higher or lower.
What is a good fan speed for GPU?

Should I run my PC fans at full speed?
Although a fan is tested for a prolonged duration at maximum speed, the manufacturer expects the fan to not always be on nor being at maximum speed. So it will wear down the fan.
Where should exhaust fans go?
Exhaust fans go on the rear or the top. Do not mount exhaust fans on the bottom of the case; since hot air rises, a bottom-firing exhaust fan will be working against physics by expelling slightly cooler air instead of warmer air. The Intake-exhaust direction should go front-to-back and bottom-to-top.
Which side of intake fan should face outside?
So the open side of the fan should face outside the case for intake fans on the front or the bottom, and it should face inside the case for fans on the rear or top. Most cases are designed with a certain directional airflow in mind–usually front to back, and bottom to top.
What is the fan on the front of a PC?
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. Advertisement.
Why is it impossible to have equal air pressure inside a case?
Equal air pressure: The same amount of fans are blowing air in and out, creating approximately the same air pressure as the surrounding room. Because of the way the internal components create blocks in airflow , it’s more or less impossible to achieve a truly equal air pressure inside a case.
How fast is a case fan?
Fast or slow: Case fans are rated at a maximum revolutions per minute, or RPM. Faster fans move more air, but slower fans are much quieter. With a compatible motherboard or a fan controller, though, you should be able to adjust your fans’ speed for the perfect balance, so this won’t matter as much.
Can a water cooled radiator be mounted on a radiator?
The radiator and fan combo itself can be mounted to the front or bottom for intake or the rear or top for exhaust, but it will be less efficient than a fan alone.
Do fans use LEDs?
LEDs and other aesthetics: some case fans use the power supplied to the fan motor to also light up LEDs, either in a single color or in a multi-colored RGB array. These look cool—especially when coupled with a “tricked out” overall build —but don’t add or detract from performance in any meaningful way.
Which fan spins faster, intake or exhaust?
More exhaust fans of the same size or larger than intake fans. The exhaust fan spins faster and is the same size compared with the intake fan. The exhaust fan has a higher airflow rate specification compared to the intake fan.
Why do I need an air filter in front of my intake fan?
A standard air filter can be installed in front of your intake fan (s) if your case doesn’t have one to ensure that cleaner and more dust-free air is drawn into your case . Because the airflow is more balanced, plenty enough air is still exhausted, which means that plenty enough air is flowing in and out.
How to test airflow in a PC case?
You can get a good idea of airflow by removing the PC case lid and feeling how much air is coming in from the intake fan (s) versus the exhaust fan (s).
What are the downsides of blower coolers?
The downside to blower style coolers would the noise and temperature. Shroud style coolers are more common and are efficient at cooling the card, but raises the internal temperature of your PC. The graphics card is the component that generates the most heat in a PC, by far, so consider your options carefully.
What is PC airflow optimization?
As you can see, PC airflow optimization is something that requires some observation and planning. Beyond that, it’s simply common sense thinking about how air moves as a result of your fan configuration and case layout. Always choose quality components when it comes to your cooling and power.
How many fans should I have on my PC?
For most mid tower cases, you will preferably want around two or three fans on the intake on the front side of your PC and one exhaust fan. If you have a larger full tower case, three intake fans at the front and one at the rear exhaust would be a good starting point.
Do fans spin at a fraction of the speed?
When you use a larger fan, a greater rate of airflow can be achieved at a lower RPM. This means that fans only have to spin at a fraction of the speed compared with smaller ones to achieve the same airflow rate.
When the fan is on, does it blow?
When the fan is set to On, it blows continuously, circulating and filtering air regardless of whether the air conditioner is in cooling mode. When the fan is set to Auto, it only blows when the air conditioner is actively cooling.
Why is my air conditioner stagnant?
The downside of this setting is that your indoor air could grow noticeably stagnant when the fan isn't running, allowing dust, pet dander, pollen and other irritants to become more concentrated in the air you breathe. This is usually the biggest issue on cooler days, when your air conditioner may be between cooling cycles for extended periods.
