If you’re a hardcore PC user and you’re looking at building a brand new rig, or to upgrade your existing one, today’s article is about the best case fans available on today’s market. If we’re talking about gaming rigs, cooling and airflow are some of the most important things to contemplate, both in terms of lifespan for your mobo, CPU and GPU, and overall performance.
When a processor runs too hot, due to work overload and/or inadequate cooling (stock CPU Coolers are not the best option for overclocking aficionados by the way), “throttling” kicks in, which means that your CPU will slow down automatically, to prevent potential damage caused by overheating. And a slower processor means less performance, which is bad if you’re a gaming-pro or if you’re using your PC for professional heavy-duty tasks. When it comes to optimal airflow and cooling, custom/high-performance case fans come into play.
Usually speaking, case fans are available in 80 mm, 120mm, 140mm, and 200mm sizes, to fit a variety of PC cases. Needless to say, a larger case fan is capable of pushing more air (eventually at a lower RPM) compared to a smaller one, i.e. a larger case fan will offer optimal airflow while keeping noise on the down-low, provided it fits one’s computer case. Bigger is better almost every time when it comes to gear once again. Also, some case fans are specifically designed to optimize airflow, using a smart fan controller or software.

Tech talk aside, let’s take care of the basics first:
How to Choose Case Fans
Some people are asking why case fans are necessary after all since both CPUs and GPUs come with their own cooling devices. The answer is that case fans remove the hot air which is thrown into the PC’s case by the CPU/GPU fans. If the hot air is not removed from the machine’s case, the CPU/GPU fans will suck the same hot-air again, thus reducing the efficiency of the cooling process, which leads to overheating issues and a drop in performance, especially on hot summer days, when you can actually hear your PC’s coolers buzzing stronger than usual.
The bottom line is that you can’t achieve proper ventilation for your professional (gaming) rig without high-performance case fans. To make a long story short, there are 2 main types of case fans: air pressure fans and static pressure fans. The former are used to push in or to pull out air, and they are used in “open places” inside the computer case, while the latter are used to “cool off” a drive bay or a radiator close to the respective fan.
CFM (Cubic Feet Per Minute)
The metric to look after when you’re choosing a case fan is CFM, which tells you the amount of air the fan can displace (cubic feet per minute). The higher the figure is, the better the fan is, performance wise.
RPM (Revolutions Per Minute)
RPM is the fan speed: the lower, the quieter the fan is, but performance may be affected by low RPM if the fan is too small. However, most case-fans nowadays are smart enough, as in they come with fan controllers which automatically adjust fan speed as required at a specific point in time.
Before buying and setting up a case fan, you must make sure it fits your case size, i.e. you must match the fan’s dimension to your PC’s case-size. As in, a 200 mm fan would be the ideal choice for a large computer case. As we already mentioned, the size of the fan is also important in regard to its performance, i.e. the amount of heat dissipated. To find out what size you need, measure the distance between the fan’s screw holes (horizontally or vertically) on your case and then add about 10-15mm. So if it’s 105 mm between screw holes, you need a 120mm fan.
If you’re into long-term investments for your rig, pay close attention to the bearing type. A case fan’s bearing type is important when it comes to overall performance and in regard to the amount of noise produced. Computer professionals and gamers alike tend to complain about noisy fans all the time, as their rigs require a lot of processing power, which generates extra heat and all that. If noise is an issue for you, you should look for ultra-quiet case fan models, provided you’re ready to pay a little bit more.
Let’s talk a little “shop” first: to begin with, there’s the sleeve bearing case fan, which is the most common of the bunch. The sleeve bearing case fans are the cheapest and simplest to manufacture, as they use a special oil to reduce friction between the fan shaft and the bearing, like most toys and gadgets on the market. Then, we have the magnetic bearing variety, which is significantly better and more “high-tech”, as there’s no contact between the bearing and the fan shaft to begin with, which translates into basically zero friction and low noise; finally, there’s the fluid dynamic bearing.
The fluid dynamic type uses fluid cycling technology and boasts the greatest life span, being also the most expensive. Oh, and they’re whisper-quiet by the way. If you’re worried about noise, pay extra attention to the decibel level specified by the manufacturer (18 dB to 35 dB or more). As the general rule of thumb, big blade fans are better in regard to airflow, quieter than smaller ones (they don’t require high RPM to work properly) and they’re perfect for exhaust vents. Then, there’s the brand thing. Some of the best case fan manufacturers include Noctua and Corsair. But as usual, quality comes at a price.
Finally, check the connector type on your PC’s motherboard. There are three connector types to deal with: 2-Pin, 3-Pin, and 4-Pin. Modern PC’s don’t use the 2-Pin type anymore, as it’s a basic on/off setup. The 3-4 Pin connectors are more efficient as they offer smart control over the case fan’s operations.
Now, let’s take a closer look at best case fans in no particular order:
