Are bigger PC fans louder?

So it turns out that if you take two fans side-by-side and run them at the same high RPM, the smaller one is actually going to be louder. If you're hoping to reduce the noise levels generated by your PC, a bunch of smaller fans is probably not what you're going to want.

Are bigger PC fans quieter?

Use Larger and Quieter Fans

Larger fans are capable of moving more air at lower RPMs, allowing them to run much quieter than smaller fans that spin faster.

Are larger or smaller fans quieter?

Remember: bigger fans push more air through the hole, but they often spin slower, which results in the same end-result of air displacement but at a much quieter, often life-extending rate (faster fans have a tendency to heat up sleeve bearings rapidly, resulting in early death of the fans).

Is 3 120mm fans better than 2 140mm?

3 x 120mm fans will provide slightly more airflow overall, but 2 x 140mm fans will be quieter, as larger fans don't need to spin as fast to provide the same level of airflow.

Will more fans make my PC louder?

The goal is to move as much air through your PC as efficiently as possible, so adding more fans will not only make your PC louder, it may also have little to no impact on the airflow of your computer.

Why is My Computer So Loud and How to Reduce PC Fan Noise

How loud is too loud for a PC?

What Causes Noise from PCs? The noise generated by a 'standard' PC typically varies from 30dB(A) to 50dB(A). This upper level is loud enough to be distracting and cause stress when working nearby for an extended amount of time.

Are bigger PC fans better?

As a general rule, though, a larger fan is going to push more air, quieter, than a smaller fan running at the same speed.

Is 3 fans overkill?

Yes, 3 fans are enough for providing good airflow in a gaming PC. You can use either two intakes and one exhaust or the opposite, depending on your case. Are 6 fans enough for a gaming PC? Six fans are overkill for most gaming PCs but if you have the budget, then go for it.

How much air can a 120mm 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.

What is the best amount of fans for a PC?

In a standard desktop PC, you want at least one intake and one exhaust fan. Some cheaper cases only include a single intake fan on the front of the PC, or a single exhaust fan at the rear. Spend a couple bucks for another fan so you have both.

What happens if your fan is too big?

A ceiling fan that's too big will overpower the room's design and visually pull the ceiling downwards; a fan that's too small won't properly circulate the air. Follow these ceiling fan size guidelines for the right proportions.

How big of a fan is too big?

Select a fan with the appropriate span: 36 inches for rooms up to 100 square feet, 42 inches for up to 200 square feet, 52 inches for up to 400 square feet, and either one 60-inch fan or two 52- or 56-inch fans for rooms larger than 400 square feet.

Does PC fan size matter?

Larger fans will push more air than smaller ones running at the same RPM. This means that larger fans can spin much more slowly than smaller ones whilst still pushing the same amount of air into your PC. Most of the time this lowers noise levels.

Are loud PC fans a problem?

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.

Do expensive PC fans make a difference?

So what's the difference between cheap fans and fans like the ones Noctua makes? Noise: Premium fans are a little quieter. Not a lot quieter, a little quieter. If you're swapping out the stock rear exhaust fan on your case for a Corsair MagLev fan … running at the same speed, you won't notice a difference in noise.

Is 8 fans in a PC too much?

Typical Airflow Demands – 3 to 5 Fans (1-2 outtake and 2-3 intake) High Airflow Demands – 6 to 8 Fans (2-3 outtake and 4-5 intake)

What size fan moves the most air?

The strongest ceiling fans offer 10,000 CFM, but an average room only needs 5,000 to 6,500. Smaller spaces will need even less than that. Because the blade span and pitch impact how cool a room feels, you should also consider the wind speed factor, which measures how fast the air is moving.

Is 120mm or 140mm better?

A 140mm fan will always be better in terms of cooling as compared to a 120mm fan if other constraints are kept constant. This is simply because the larger blades on the 140mm fan allow it to push more air as compared to a 120mm fan running at the same RPM.

What is considered high airflow in a fan?

Fans that can move air at over 7,000 cubic feet per minute (CFM) are considered high airflow or powerful fans.

Is 4 fans enough for a high end gaming PC?

No, four fans may not be enough for a gaming PC. Generally, larger gaming PCs will require more fans in order to ensure proper cooling. Depending on the size of the PC case, five to seven fans may be necessary. It is also important to consider the quality and placement of the fans.

Is Liquid cooling worth it?

In other words, it's more efficient, and often quieter. If you want the lowest possible temperatures, or if you're interested in a quieter solution and don't mind a slightly more complex installation process, liquid cooling is probably the best option.

Can you overuse fans?

Be smart and do not overuse your ceiling fan

Sure, your ceiling fan can run throughout the day and night without issue but running it for several days or months on end may not be the smartest choice and will reduce the overall lifetime of your fan.

Which PC fans should be exhaust?

Generally, you want the case fans in front of the case drawing in air while the fans at the rear blow air out. If your case has vents at the top, they should be placed as exhaust fans because hot air will rise. Side-mounted fans should be used for intake, though they often don't have air filters.

Is a full tower better for cooling?

A full tower won't only give you space for a larger radiator, it'll provide you with room for more radiators. This can be handy for cooling high-end, power-hungry components, especially if you're overclocking.
