Product Information

Choosing the best case fans for your rig depends a lot on what you need out of your PC’s cooling solution. Some fans excel at near-silent running, while others crank the fan speeds up to push as much air as possible to feed your hot, power-hungry PC components regardless of noise. It’s all about finding the right fan for the job. Low Profile coolers (also known as top blowers) are active coolers, which usually use a slightly wider and flatter heat sink on which a fan is mounted. The airflow is thus directed directly toward the CPU / motherboard. The advantage of this cooler is the more compact design, which makes it more common in smaller PC cases. In addition to the CPU, other mainboard components (memory, controller) are cooled slightly, too. The fans from the brands Noctua, Corsair and the majority of the models from be quiet! do not stand out much in this 120 mm case fan test. Overall, these brands fill the midfield, which is not a bad performance by any means, but just not an outstanding victory that might have been attributed to them without the comparison. At least it is noticeable that the Corsair QL120 does better than the 140 mm models from the corresponding parallel test. Conclusion

Value is all well and good, but what if you have the money to spare and want a truly premium case fan? If that sounds like you, you’ll want to make a beeline for Noctua’s NF-A12x25 PWM and NF-A14 PWM case fans. They’re modern classics of the case fan world for good reasons.

Although nicer fans still aren’t that expensive (relative to other PC components), you still get what you pay for. Ball bearings, often found in the least expensive fans, tend to fail more often, while sleeve bearings are a step up in quality and longevity, and fluid bearings tend to be the most reliable, with the longest lifespans. Unlike most PC components, fans are mechanical systems meant to run continuously for years, so get good ones! The three DeepCool fans are therefore also the budget recommendation for very quiet systems. The FK120, FC120 and CF120 do not give much in this comparison: They offer decent performance even at low speeds. Arctic’s P12 and P14 pressure-optimized case fans aren’t the outright best-performing fans you can buy, nor are they particularly premium. But what they do offer is virtually top-tier performance for budget-tier pricing. They’re incredible value, and we think that makes both of these fans excellent choices for almost any PC builder out there. Noctua makes a few different versions, but the ones we’re interested in are the 3000 RPM versions, which are the best airflow fans in the range. Both the 120 mm and 140 mm versions offer more than 100 CFM of airflow, with the 140 mm fan, in particular, impressing with its 158.5 CFM. Static pressure is also impressive, and the 120 mm fan takes the cake here with a staggering 7.63 mm-H2O.

A surprisingly high performance has the DeepCool CF120, which achieved the best temperature results at the RPM, but due to the higher volume they are found a bit further down the list. The very loud and weak Alseye X12 attracted negative attention. Case fan at uniform 31 dB(A)

Closing Thoughts

So, on paper, you should be able to run the P14 PWM at 1500 RPM (or less) and achieve cooling performance on par with the P12 PWM. If the 120 and 140 mm fans have a similar price, you might as well go with larger fans if they’ll fit in your case. Speaking of moving air, the stat you want to keep your eyes out for is “CFM,” which stands for “cubic feet per minute.” The higher the number, the more air the fan can move, the better. That said, fans with the highest CFM also tend to be loudest. In this test, the temperatures and the noise development are added together. Therefore, it is not surprising that the fans that combine good performance with low noise are at the top. Cooler Master’s Mobius 120 in the regular and RGB versions are at the top together with MSI’s Silent Gale P12. Those who would have expected the Noctua NF-A12x25, which is considered revolutionary and has received a lot of praise, to be at the top will be somewhat disappointed in this case. While these offer good performance as case fans and are quiet, they are definitely beaten by other models in this area.

I have to admit that I hadn’t heard of the Cooler Master Mobius before the case fan review of the 120mm fans, and I was definitely surprised by them. The same goes for the MSI Silent Gale P12s, which at first glance seem similar in design to the Noctua NF-A12x25s, but perform better as case fans. Due to the lower maximum speed, they fall a bit short in the final test, but they offer excellent performance in a normal volume setting. Let’s take Arctic’s 140 mm P14 and 120 mm P12 for example. The P14 boasts 72.8 CFM of airflow and 2.40 mm-H2O of static pressure at 1700 RPM. The P12, on the other hand, offers 56.3 CFM and 2.20 mm-H2O at a slightly higher 1800 RPM.

Fans

Of the two, the 120 mm P12 strikes us as the better choice, at least as far as value goes. Its 56.3 CFM of airflow and 2.20 mm-H2O of static pressure place it only slightly behind Noctua’s top-tier offerings for cooling performance. The P14 is still great, and it’s the case fan I use in my rig, but it lags a bit further behind Noctua’s equivalent 140 mm fan than the P12. The NF-A12x25 PWM and the NF-A14 PWM are static pressure-focused fans, but they also offer more than enough airflow to make them viable for every position in a PC case. We particularly like the NF-A14 as an all-purpose cooling solution. Its 82.5 CFM of airflow trumps even some airflow-focused fans while still offering a decent 2.08 mm-H2O of static pressure for pulling air through dust filters and other intake obstructions. First, make sure you measure your PC case to make sure the fan you want will fit in the mounts your case has. Standard sizes range from 80mm to 250mm, and you’ll generally need larger fans for larger PC cases, since they’ll need to move more air. 120mm and 140mm also (normally) have the same mount size, and larger fans are generally quieter and move more air. Most of the fans on our list use PWM, or pulse width modulation. PWM allows for fine-grained control of fan speeds without manipulating fan voltage. The main advantage of this approach is that it lets you slow fans down and even stop them without any adverse effects. Most voltage-controlled fans will stall below 5 volts, which stops them from working at ultra-low speeds. So PWM is important for achieving those 200 to 500 RPM speeds that silence enthusiasts may want. Adding two top intakes reduced CPU temperatures by a single degree and raised GPU temperatures by the same amount, although that may just be run-to-run variance. Even if it isn’t, a single degree Celsius reduction in CPU temps isn’t worth the additional cost of two extra fans.

The Cooler Master Mobius 120P ARGB are thus also the strongest RGB fans in this test run, are followed by the RGB version of the DeepCool FC120 and the ENDORFY Fluctus 120 PWM ARGB.By far the weakest fans in this test remain the Alseye X12, apart from that the last places are occupied by the NZXT F120 RGB and the Alphacool Aurora Rise. Case fan at maximum power There are two types of PC case fans: static pressure fans and airflow fans. Static pressure fans excel at pulling or pushing air through restrictions such as dust filters, radiators, and drive cages. On the other hand, airflow fans work best at moving air as fast as possible, at the cost of reduced performance through the restrictions mentioned above.
