If you have one of the best CPUs for gaming, you might want a fan to keep it cool. The model works up to its claim with the RGB LED system and has multiple patterns, such as Mirage and Stars. The company follows a top-down approach for cooling with a 92mm PWM fan operating at speeds between 600-2400 RPM.
This decibel level is specified at 30 dBA at maximum speed. You will not need an RGB board as this unit comes with a handy remote. You may want to take the term low-profile not very seriously with this one as the model is 75mm high, which almost doubles the size of other similar options.
That being said, it’s an excellent choice and certainly more compatible than other low profile CPU coolers on the market. Lastly, the cooler comes with a 2-year warranty.
– Our Verdict:
The Cooler Master MasterAir G100M’s is uniquely designed that funnels the air from the fan descending onto the bigger copper cooling column right in the center of the heatsink. This offers the cooler great aesthetics, especially with the built-in RGB lights that give off the radiant glow through the fan.
The cooler is short enough to make it a great ITX CPU cooler. Though remember the design of this cooler can restrict some RAM from fitting into certain motherboards. Considering the fact that cooler gets somewhat broader towards the center, it may encroach on some taller RAM units.
This is more applicable when the motherboard has the RAM slots particularly close to the CPU socket. This CPU cooler offers a strong performance for its size with 130W of cooling while operating at 30dBA. Up to the mark performance!
How To Choose The Best Low Profile CPU Cooler?
A low profile CPU cooler might look simple to you. Though remember, there are multiple things to consider before making a choice. If you have not done proper research and selection, it may affect your PC, and you might not be able to operate it efficiently.
When speaking of the fitting, we don’t mean the low profile cooler should physically fit your PC. Though it’s essential! One problematic part is whether it will perfectly fit the CPU socket of your motherboard. As the space around the CPU socket is confined, you need to consider the size.
Keep in mind that size matters. Any sort of physical interference in your PC box is not wanted at all and a way to several other problems. As the cooler is low profile, it still doesn’t mean its compact enough to fit almost anywhere. You need to consider the dimensions.
One important feature of this cooler is its efficiency. They operate quite silently. You may want to use the space as much as possible – bigger is better.
2- 3 Pin Or 4 Pin Connectors
Four pin connectors must be your goal and definitely for good reasons. Well, the adjustability it offers is way beyond the three-pin connector. You can also modify the speed and volume of the fan using four-pin connectors. You can do it either through the motherboards or some software.
When we talk about three pin connectors, you won’t be able to make those adjustments. Make sure to double-check whether your motherboard can support four-pin connectors.
If yes, you can’t go wrong with it. You can even run three-pin connectors. Though if the motherboard has three-pin headers, you cannot run four-pin connectors.
You might be thinking who would care about the cooler aesthetics? No one will notice it since it will be incorporated inside your PC. Those who care about it, there are diverse shapes and designs you might be interested in instead of simply some classic blades running in circles.
Another important consideration is the noise of your cooler. All low profile coolers on the list above operate quietly and even the loudest one can only reach 30 decibels. This noise level is very much similar as you are sitting in a library. Technically speaking, a noisy fan doesn’t hurt you, it only disturbs you.
However, if you wear headphones while using your system, you are unlikely to notice or get disturbed by the noise. One of the most frequent uses for small form factor builds is in entertaining hubs where even very silent fans can eventually affect your experience.
If you are searching for the quietest low profile coolers, you may want to consider Noctua. In this buyer’s guide, we have reviewed Noctua NH-L9i which produces less than 24 decibels of noise. In most cases, it is just inaudible. You may also consider other options and check out their noise generation capacity.
Obviously, you don’t want to make your system sound like its launching to the Moon. Isn’t it? Remember the small coolers are more likely to be the loudest ones. There are two things that you must consider. Firstly, the manufacturer mentions the noise ratings and the second is users’ reviews. Once you consider both of these aspects, you will be able to make an informed decision.
5- Thermal Design Power
To simplify it, TDP is the representation of power. It is referred to as the maximum power a unit can generate while operating real applications. If you have a PC that run’s a little hot, you should primarily consider high TDP coolers to keep everything cool. For instance, the average is around 100W TDP.
Everything more than this will do the job correctly done. Thermal design power or TDP measures the cooling power a given CPU cooler offers. Typically, it is calculated in watts of energy. This is the approximate amount of heat that the cooler can dissipate, which means high numbers equate to enhanced cooling.
When considering TDP, you need to keep in mind that things change because of other factors. If your system doesn’t come with adequate airflow and case fans, then your cooler is more likely to operate less effectively.
Due to this, when selecting a low profile CPU cooler, you will want to consider your CPU’s TDP and then get a fan that can manage a little more. More specifically, Intel has been renowned for giving all their CPUs from a generation the same TDP as a spec.
In reality, people can see that it’s not always the case. For this purpose, you should go through the official website as a reference if you are uncertain about the CPU’s TDP. Also, you can always check your CPU manual.
You will frequently find the highest TDP coolers on the list, which offers quite impressive cooling power. These coolers can easily handle any CPU and even overclocking.
6- CPU Cooler Style
Different from the world of GPU coolers, you will typically find two styles of CPU cooler, including air-based systems and liquid CPU coolers. Both get the job correctly done, though the liquid option is a more popular choice when it comes to choosing the finest low profile CPU cooler for overclocking.
An effective air cooler works up to the mark and comes relatively cheaper. Air cooler primarily depends on the fan and heatsink. The heatsink is generally built from thermos-conductive materials such as aluminum or a mix of aluminum and copper.
It draws heat away from the CPU while the fan keeps on spinning to keep cool air running through the heatsink and avoid it from overheating. Liquid cooling is relatively more complicated since it involves multiple parts, including the pump, hoses, radiator, and fan.
Similar to air cooling, liquid cooling follows a similar approach. It uses liquid as a substitute for air. Liquid coolant or water is propelled through the hoses, which secure the component that requires cooling, which is referred to as CPU in this case.
Simply circulating it is not sufficient, and therefore liquid requires its specific heatsink. This is more precisely the role of the radiator in a liquid cooling system. To prevent overheating, there is a fan that keeps the air cool.
7- Compatibility And Size
No matter if you want to have an RGB CPU cooler or something very simple, compatibility is one of the most important aspects to consider. Carefully go through the specifications readily available. If you are busy, still don’t forget to check out the TDP rating along with the overall dimensions of the cooler.
With low profile coolers, height is an obvious consideration. Though it has nothing to do with compatibility, you need to consider the decibel level. Some fans are significantly silent than others.
Naturally, you will want to look at the size of the low profile cooler. The most crucial measurement is to check the height of the cooler as this is typically where most CPU coolers interfere with the case.
By looking at the case’s manual, you will see how much clearance your case offers for the cooler, which is mostly in millimeters. Also, it’s vital to ensure the size of the cooler doesn’t interfere with the RAM. If your memory units are next to the CPU, then a cooler that is broader at the top will work nicely.
8- Warranty & Price
When it comes to buying PC components, warranty is an essential yet often overlooked area. This differs from a few years to close to a decade. Though price frequently dictates the warranty duration.
Finally, it’s about your hard-earned cash! While speaking of coolers, we are more specifically talking about your PC’s insurance.
A good CPU cooler is practically insurance for a user as they receive optimal performance throughout the upcoming 7-8 years. Investing some more bucks is a smart approach, especially if you have bought a CPU for $500 or even more.
