There are many benefits to using this open air PC case. There are some that excel in one area more than others. This is evident when a case that looks very gaming-like but does not have enough real estate for airflow can be used. Fractal Design Meshify C is an excellent example of this. This case not only features a great airflow design but also has graphics that will make you feel like a gamer.
Fractal Design Meshify C has an all-black design that we have never seen before. The all-black design allows it to blend with almost any gaming setup.

Factors to Watch Out For Best Open Air Case
Fan Sizes & Mounts
Fan mounts are available in two sizes for the best open air PC cases: 120 mm or 140 mm. These are the measurements of the fan’s four sides. Although 120mm fans are the most common, 140mm fans can also be very useful. Noise is the main reason you should choose a 140mm fan over a 120mm fan. Larger fans can move more air at a lower noise than smaller fans. However, 120mm fans are still the most efficient in terms of airflow performance.
This is the most detrimental for airflow. While a solid front panel might look nice, if there are no vents on the chassis to allow for airflow, your airflow and temperatures will suffer. Do not purchase a case that has a solid front panel if performance and airflow are your main concerns.
Similar to the above, but better. Manufacturers have begun to use this technique to compromise between performance and aesthetics as more people are aware that solid front panels can block airflow. This can be achieved by creating a large gap between intake fans and glass, which is usually covered by a dust filter. Vents mounted on the sides or full-on side fans mounts might be an option.
This is an interesting option and one that has been increasing in popularity with Cooler Master cases. Although it isn’t the most efficient option, it is certainly better than a solid front panel. This is a good compromise between aesthetics and performance. However, perforated metal may not be as pleasing to the eye for everyone.
It is best to just take off your front panel. Mesh is a great option because it prevents air from getting blocked in any place and only requires minimal fan power to pull air through. Mesh’s excellent airflow performance makes it our preferred choice for cases. Third-party testing also confirms that it is the best.
Frequently Asked Questions (FAQs)
Q1. Is open case airflow beneficial?
Contrary to popular belief, closed-case PC cases are more dusty than open-air ones. This is because there are more corners and gaps. Open air cases, on the other hand, allow airflow through without obstructions so dust is less likely to get stuck inside.
Q2. Do open air case provide better cooling?
Keeping the ventilation grills at the bottom of the case clean can prevent dust from collecting on the vents without compromising airflow or temperature. Also, keeping your room clean in general can help prevent other problems besides overheating components. Therefore, open cases are not better at cooling.
Q3. Is there a way to increase the airflow in my case?
The case should allow air to flow in a straight line. The case fans should be located in the front of the case to draw in air, while the fans at either the rear or back blow out air. Vents located at the top of your case should be used as exhaust fans to prevent hot air from rising.
Q4. What is the optimal number of fans to install?
It all depends on your budget and aesthetic preferences. However, fans with more fans will generally provide a cooler environment. Fans can have diminishing returns. If you have 3 fan options, 2 intake fans and 1 exhaust fan is the best price-to-performance ratio. You will also have positive pressure in the case, which will reduce dust buildup and increase your temperature. This configuration will allow you to increase your temperature by installing 3 intake fans & 3 exhaust fans.
Q5. How are the GPU & CPU affected by airflow?
Your GPU and CPU have their own coolers but they still need cool air to get the best results. You can ensure that both components receive the cool air they require to reach peak cooling performance by using a positive pressure configuration. They will be able to run faster clock speeds and for longer periods of time, which will result in an insignificant improvement in performance.
Q6. Does the fan RPM make a difference?
Although fan RPM can have an effect on performance and acoustics, it is not enough to worry most consumers. The fan RPM of your case determines the pressure in your case. This is true regardless of whether the intake fans are the same number as the exhaust fans. Fans with higher RPM ceilings have the ability to move more air. This can help in thermal performance. However, this comes at the cost of acoustics. When it comes to fan RPM and the number of fans, it is a delicate balance.
