What is the Quietest CPU Cooler in 2021 – Best Review!

Looking to know What is the Quietest CPU Cooler? Read on to know more about it.

Are you looking for the quietest CPU cooler? If so, then this is the right place. You will find reviews on some of the best products that are available today. We also have a review on how to choose what type of cooling system would be perfect for your needs and budget.

The first step is deciding whether or not you need a fan at all: passive cooling may work better in some situations than others. The second decision involves picking out an appropriate size and style of fan: we discuss two popular types of fans, namely axial and centrifugal, as well as their pros and cons. We then review the best quiet CPU cooler fans for each type.

Finally, we provide some information on how to choose the right fan for you and your needs.

Quietest CPU Cooler Test Methodology

Our test system is based around an ASUS P5E motherboard (Intel X48 chipset), which has one Intel built-in northbridge and one ICH10 southbridge chipset.

It is a full ATX motherboard with both an integrated graphics card and a sound card onboard. This allows for realistic noise testing, as the motherboard’s built-in audio DACs are used to playback the test tones of each fan. We use a Sigmatel STAC9750 USB sound card for our testing.

Test Procedure:

1- Install all fans onto the motherboard (the test system is built into a Silverstone TJ09 case).

2- Boot up and install drivers for the audio codec and sound card.

3- Make sure that you have turned off automatic fan control in both BIOS and Windows to prevent PWM fans from changing speeds.

4- Install the latest drivers for the motherboard’s integrated audio controller.

5- Reboot and enter the BIOS to make sure that all fans are detected correctly, by checking CPU fan speed, chassis fan speeds, and temperatures.

6- Make sure that your sound card is set to Full Duplex mode.

7- Using a free audio editing program such as Audacity, record ~10 seconds of white noise from the sound card’s line input.

8- The recording should be level normalized and saved as a .wav file.

9- The recorded .wav files will then be played using a free audio playback program called Cool Edit.

10- Measure the dbA level of each fan using a sound pressure level meter (~30 cm away from the fans). 11- Record all dBAs at full speed.

12- Multiply each dbA reading by 2 to get the fan’s noise level in dBA.

The only reason that there are two different scales for A-weighted measurements is because of differences between instruments. The A-weighted scale assumes that the human ear is less sensitive at lower sound pressures, so the true dB level of a quiet fan running at low speeds may not be 20 dBA lower than its measured noise level.

How to Choose Quietest CPU Cooler

Choosing the right CPU cooler can be tricky. There are so many types of coolers to choose from, and all you want is the best one for your computer. To help you out, we’ve answered some common questions below.

1) What’s the difference between a stock cooler and an aftermarket cooler?

 Stock coolers come with new computers or when they’re purchased separately. They work well enough if you don’t overclock your processor too much, but if you do then it might not be sufficient enough to handle them. Aftermarket coolers are designed specifically for overclocking processors and can keep up in most cases.

2) How do I install my CPU Cooler? 

The first step is to find an open expansion slot on your motherboard and unplug the power connector for it. Older motherboards can be finicky about CPU coolers, so if you’re having trouble getting one in, try another expansion slot or consult your manual for help. After that, remove your old heatsink and apply thermal paste to the top of your CPU. Now install the new heatsink and plug the power connector back into your motherboard.

3) What is a liquid cooler? 

A liquid cooler is similar to an aftermarket CPU cooler but keeps your processor cool using liquid rather than air. Liquid cooling usually results in better temperature performance as well as quieter operation, as stock coolers sometimes tend to be loud. However, most liquid coolers are only compatible with sockets that allow for overclocking.

4) What is a tower cooler? 

A tower cooler sits horizontally on top of your processor, taking up less space than traditional coolers. It’s designed especially for small cases without much clearance, so it’s more compact and lightweight than other options. However, tall tower coolers can sometimes interfere with other components on your motherboard, so make sure to check your case and its specs before buying one.

5) What is a low-profile cooler? 

A low-profile cooler is designed for the same kind of users as tower coolers, but it’s even smaller and lighter than them. If you have a small chassis that won’t allow for larger coolers, then a low-profile cooler is ideal.

6) What are C-style coolers? 

C-style coolers are designed to sit in an upright position rather than on top of your processor horizontally like most aftermarket coolers. They stay out of the way better in small chassis and usually cost less than other options, but are less effective at cooling your CPU.

7) What is a fan speed controller? 

A fan speed controller allows you to manually adjust your CPU cooler’s speed by turning a knob on the front of it. This is usually cheaper than buying multiple coolers so you can manage noise levels. If you have two or more fans that need to be adjusted, then a fan speed controller can come in handy.

8) What is a water block? 

A water block is an alternative option for keeping your processor cool that works with liquids as well as air. Waterblocks are usually more expensive than other options, so they’re better for those looking for the best cooling experience money can buy.

9) What other types of CPU coolers are there? 

Besides tower coolers, low-profile coolers, and water blocks, there are also liquid-air hybrid cooling systems that use both air and liquid to keep your processor as cool as possible. Other than that, you can find self-contained water cooling systems like Corsair’s Hydro Series H80i v2 All-In-One Liquid CPU Cooler.

10) How much should I spend on a CPU cooler?

 There is no specific price range for buying the best CPU cooler; it all depends on what you’re looking for in one and how much money you’re willing to spend. Some high-end aftermarket coolers go up well over $200. If you’re not looking to spend a lot, there are still lower-priced options available. Most aftermarket coolers usually start around $20.

Quietest CPU Cooler – Conclusion

CPU coolers come in many different styles and sizes with varying price ranges. They can be made from any sort of material and for a wide range of budgets. Some CPU coolers require more complicated installation than others, but most will fit into an open expansion slot on your motherboard without much trouble.

You need to determine how much cooling you need before buying a cooler so that it’s neither overkill nor too weak for your processor. To do this, check the TDP of your processor as well as its heat output under load.

This is especially important if you plan on overclocking your processor, as heat generation becomes exponentially higher with each increase to clock speed. Aftermarket coolers are generally better at cooling than stock ones, though they can sometimes be louder or more difficult to install.

There you have it: everything you need to know about choosing your CPU cooler. Good luck and happy hunting.
