Buyer’s Guide: All You Need To Know About The Best CPU Air Cooller

What Is CPU Air Cooler?

The best CPU air coolers are attachable or installed systems that blow cold air into your PC to help keep the main compartments cold. By doing so, you can lower the overall temperature of your system. This, in turn, helps expand your CPU’s lifespan and keeps the system from burning out.

Why CPU Air Cooler Is Necessary?

If you want to preserve the life of your system and also extend the lifespan of other parts, you will need a very efficient cooling system. Why would you want an air cool specifically? This is because it’s a safer method for keeping your system cold, especially if you find the best CPU camera reviews. Air coolers don’t require any complicated installations, can be inside or outside of your computer, and don’t need the use of carefully placed thermal paste.

What Is The Best Budget CPU Cooler For Gaming?

One of the best budget CPU coolers is the Deepcool Gammaxx 400. It features a PWM CPU fan which includes LED lights and has four different powered heat pipes. It comes with extra fan clips, which can also be useful if you’re attaching many fans. Lastly, this unit is affordable and is suitable for any setup. The CPU cooler reviews also state that it’s the most affordable option.

How Do You Cool Down Your CPU?

There are two main ways to keep your CPU cool, either by using the best CPU liquid cooler or the best CPU air cooler. Each of these types provides you with pros and cons, which will be dependent on your preferences. Other than that, you can try to prop a window open, use your PC minimally, and cut down on the types of programs that you use. However, it’s much easier to go with a more relaxed option.

What Kind Of Liquid Is In A CPU Cooler?

A majority of best CPU cooler liquids are made from a mixture of water, deionized water, glycol, and water dielectric alloys. These types of ingredients are excellent at conducting heat and are the most common ingredients used.

Knowing the different types of coolers can help you make a better choice on which one will work for your setup. Here’s a quick overview of the two types of good CPU coolers on the market.

Air Cooling System

Air cooling systems are going to be the most common you find as they work well and are incredibly efficient at lowering the core temperature of your CPU. They are relatively inexpensive, though some models will also range on the higher range end. These fans work to push the best fresh air into your system and regulate the temperature of the inside of your system. Heat dissipates and produces a lower temperature for your CPU. It’s the most versatile in terms of cooling systems and also features compatibility.

Liquid Cooling System

The next type is called a liquid cooling system. If you’re looking for an upgraded and enhanced system, then these are better. They feature quieter operation, have better setups, and also look aesthetically pleasing. That being said, the liquid is best for those who like to overclock their systems or have their games running on full graphics settings. The only downside is that you will need to change out the pump.

How To Choose The Best CPU Air Cooler

Upgrade necessity

Well, you may not be inclined to switch your current cooling system as you may think that it’s sufficient. However, there’s always going to be a model that functions better than your current setup. Technology grows at fast rates, which means sometimes it’s hard to keep up with what’s the best CPU cooling system. Here are a few reasons as to why you should upgrade:

  • Overclocking
  • Noise Reduction
  • System Upgrades
  • Running Hardcore Software
  • System Damages
  • CPU Cooler Designs

CPU Air Cooler Orientation

This is the next aspect you should consider. Tower Style CPU Coolers may be installed in two variations; the first pulls air from in front of your PC casing while the others pull air from around the CPU. Choosing the best one over the other might be better for your setup. Be sure to do some research as each position has its list of positives and negatives. Downdraft CPU Coolers: The other type is downdraft coolers. These function by rewriting the airflow down and then allowing it to rise and cool down your entire system. These types are often utilized in low profile CPU and can easily fit inside a PC case, making it accessible and easy to install.

Verdict and our recommendation for 2021

The best CPU air cooler can make a significant impact on the performance and lifespan of your computer. If you haven’t installed one already, we highly suggest you pick one off of homemakerguide best CPU cooler list, as this can help regulate your PC’s temperature. Even if you’re not overclocking your computer, running powerful programs, or steaming, you should still have a cooler. Overall, you’ll find that a low-end cooler can keep your CPU at room temperature, which boosts the performance of your computer. There are many affordable types, which make it even easier to find one that’s compatible with your computer type. Before you go out and buy the best CPU cooler, be sure to pay attention to the specific buying considerations, as you don’t want to purchase one that will stop working, always read the reviews. A majority of cooling systems will only be compatible with specific types of rigs, so double check to see if the one you’re interested in works for your type of computer.

Also, beware that some cooling systems won’t work in computer cases, as they are large and may only be fit to have on the outside of the system.

Lastly, decide if you want an air or liquid cooler, as the functions will be different in them. If we had to choose one to be the best CPU cooler, we’d have to select Noctua NH-U14S because it features the best combination of price and performance. It’s easy to install a system that is highly optimizable and has full compatibility with most PCs. The most power it delivers is 150mm through the fan and can help regulate your system and bring it down to shallow temperatures. The only downside we’ve found from the reviews is that it is tremendous and you may need some expertise to fit it into your computer case. However, any of them on our list is the best CPU cooler 2021.
