best buy computer fans This is a topic that many people are looking for. star-trek-voyager.net is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, star-trek-voyager.net would like to introduce to you How To Choose The BEST Fans For Your PC Build. Following along are instructions in the video below:
“Choosing the right fan for your system is quite important for cooling for system noise. Noise. And for the looks of course and in this video. I want to break all the important terminology when it comes to specification of fans what to look out for depending on your situation.
Now we ve done similar thing for the power supplies check it out over here and huge things to be quiet for sponsoring. This video. A o seas warranty just respawned that covers four years general warranty for any defects. Including a one time accidental warranty replacement of aegon monitors.
Because sometimes things happen. So you can enjoy a super. Smooth and responsive gameplay. Just like the warranty check it out below.
So first quick specification is the size and that is the measurement of the frame and millimeters not of the blades ranging from really tiny 25 mil or fans. All the way up to 230 member of fans with 120 and 140. Ml sizes being the most commonly used on cases and coolers. While the default thickness of the fan is 25 millimeters.
Which is perfectly fine for majority of situations. But be mindful there are really low profile fans that exist for particular small form factor situations. Where this thing will not fit. And just be mindful that all specifications on the box are measured at maximum rpm of that particular fan next up is airflow.
Which is one most important specs usually measured in cfm that stands for cubic feet per minute and sometimes you also see a measurement in cubic meters per hour in different regions and you can use this conversion rate to give you cfm. If that s not displayed and obviously the higher the number. The more air. The fan can move so for.
140 miller. Sandwich. 3 fan has a cfm of v. 95.
But what does that mean so. Let s use a fun example with the dark. Base pro 900 draft to that end. Volume is approximately 28.
9. Cubic. Feet. This means that our fan can replace the entire volume of air inside the case 20 times in one minute or every 3 seconds.
Now imagine you have three of those fans set up for exhaust at full rpm. Without any restriction whatsoever. That means you re tripling. The cfm mount and you re placing the entire volume of air inside that enclosure per second that is kind of crazy.
I do want to clarify the these maximum cfm and static pressure values cannot be reached in a confined space like a computer case. Because they only apply to an ideal environment with no obstruction. There also if the case was letting air through without resistance at all so treat. These specs.
As general guidelines. Now the cfm spec is based on the blade design and the frame design. But more importantly. It is based on the speed of the fan measured in rpm.
So a bigger fan will always move more air at the same speed as the smaller fan so two of these 140 male fans are about the same total cfm as three 120mm models..
But let s be real most of us are not running full speed on all fans at all times. Which is why pwm control is so important with today s fans. So pwm stands for pulse width. Modulation and that is indicated by a four pin connector instead of a three pin connector so when you plug a pwm fan into a four pin pwm fan header on your motherboard you can do all types of cool stuff like full precise control of the rpm range you can set the rpm to reflect on hardware temperatures and like spike up to 100 rpm.
When cpu load is high or something like that and you can also do really low rpm with pwm for like really silent. Almost inaudible operations well for three pin fans. Precise rpm control is not possible. But some other boards allow for voltage control for those three pin fan headers like five seven or 12.
Volts. Therefore. Adjusting the rpm based on the voltage supply to the fan. And you can also get voltage reducing adapters to reduce the fan speed from it s constantly running at 12 volts.
Which is a hundred percent load to something lower and so moving on what happens when we have air flow resistance from cpu towers radiators case elements and that is when static pressure or air pressure is super. Important to talk about it is measured. The new mieux of water or millimeter of water gauge or millimeter of water column or pascal depending on the brand. So the higher the static pressure.
The better the fan can force air through whatever resistance is on either side and the fan. So blade design is crucial for this which is why they re much wider than your air flow fans. But so is the rpm where some industrial versions of fan deliver insane amount of static pressure. But at crazy high speeds and of course.
Noise levels here s a visual distinction between high static. Pressure and low static. Pressure. And that air penetration through the standard 25 billion.
And just how much more air is being pushed through those fins with high static pressure versus low static pressure and since be quiet prioritizes on silence. They do have their high speed variations of fans that deliver much higher rpm 4. 1. And also much better static pressure.
And when shopping for fans. You can see that some brands choose to clearly indicate what the fan is designed for either static pressure or airflow. While some fans are more like a hybrid that can be used in either for air flow or mounted on the heatsink or high resistant areas on enclosure. Another important factor to consider here is noise level measured in decibels and in my experience.
Anything around 20 and lower dba is basically inaudible even when you combine multiple fans for a really quiet system. I ve done a few of those and they ve been really satisfying and just like turning things on and things are spinning. But you can t hear anything. But the temperatures are still fine that s a good feeling.
The silence. Factor is definitely one of the reasons. Why i love silent wingstreet. It s my top 5 favorite fans.
They ve done a really good job with the blade design the frame structure and the six pole fan motor instead of a traditional 4 pole design. So each rotation is literally smoother and quieter as a result and finally bearing type also has an important part to play and a noise profile. But also the longevity of a fan now some brands specified the lifespan in hours. Ranging.
From 40000. To 50000. To. 80000 hours with.
Bearing over. 150000. Hours with ufb and 300000. Hours with fluid dynamic bearing like on the silent wings.
3. That is 34 years of continuous operation. That is what the bearing is rated at that is kind of insane and so hopefully this gives you a good baseline of understanding all these specifications when it comes to fans and help you choose the right thing for the job. The most interesting thing for me is doing all those cfm calculations and how many fans at what cfm you need to replace entire volume of air in a particular.
Enclosure per second. That s a cool way to think about when you re trying you visualize. How many fans you need for a particular system and also understanding there must exist a good balance between noise levels and. Rpm which is why i love the sound weeks3.
So much. But figuring out that balance is kind of a fun part especially when you re dealing with pwm control and setting little curves based on cpu temperatures. And all that stuff that is the fun part when it comes to setting up your entire case with airflow and hopefully. Temperatures are all good to the power color rx.
