  • Not one for the overclockers

The Cooler Master GeminII M4 comes with the direct contact technique of switching heat away from the CPU. As a substitute to the heat pipes passing through the contact base, in this process, they are compacted and become a fundamental part of the bottom of the contact plate.

That way, it directly touches the heat shield on the topmost of the CPU. To get to its incredibly low height profile i.e., 59mm tall, the cooler uses four regular 6mm U-shaped heat pipes that allow a more compact design. The newly-designed XtraFlow 120mm fan sits on the top of the cooler and is only 15mm thick.

The Cooler Master GeminII M4 is designed to be easily used in heavy overclocking circumstances. It doesn’t encounter any issues and keep the CPU cool even under the heaviest load.

- Our Verdict:

Cooler Master GeminII M4 is one of the best low profile coolers designed for a system with restricted space such as a small desktop, HTPC, and mini-ITX. Equipped with unique heat pipe layout and four direct contact heat pipes, not only it is compact but offers exceptional cooling performance.

Are you looking for a low profile cooler that’s compact and obeys the zero interference rule? Cryorig has the perfect solution for your build, and here we have Cryorig C7-47mm. The cooler is built in a way to steer clear of PCI-E and RAM while at the same time keep your Intel processor or AMD cool.

Cryorig C7 is one of the shortest coolers we have seen so far with a height of 47mm from top to bottom. At 97mm x 97mm, it won’t take a lot of space. Also, the mounting kit is good enough though you need to flip the motherboard over for the backplate, which is relatively easier.

Further, the 57 fin heatsink is nickel plated with a copper bottom and four finest quality pipes, whereas the PWM fan comes with high speeds between 600 – 2,500 RPM. This is another CPU cooler that stands to its claim. It is capable of handling an extensive range of boards with a TDP of about 100w.

If you have an Intel system, you will be happy to go with many compatibility options. Also, it makes a great choice for AMD users. Lastly, the Cryorig C7 comes with a 3-years warranty and offers good value for the money.

- Our Verdict:

Undoubtedly, Cryorig C7 offers good value for money. It is notch above a stock cooler in both performance and noise generation. However, it still needs to struggle for being the quietest low profile CPU cooler that runs at top speed.

One drawback of the cooler is that it is not compatible with the AM4 socket and therefore requires a separate upgraded kit for it. This is pretty common for coolers that were launched before the release of the Ryzen CPUs. Other than this, the C7 performs exceptionally.

Its performance can be easily matched with more expensive coolers. Indeed, it’s the best value cooler if you are looking forward to a solid upgrade that won’t bring down the temperature. Finally, it significantly reduces the noise levels when your system is under heavy load.

Fan-based CPU coolers are not very feisty, particularly when compared to GPU coolers and liquid systems. The MasterAir G100M is an exception and a colorful choice, especially if you searching for something with some more flair.

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.

1- Fitting

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.

3- Aesthetics

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.

4- Noise

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.

Thermal Design Power​

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.

Air and liquid cpu coolers

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.
