![]() The reason for this popularity is that sleeve-bearing fans don’t perform well at high temperatures or in a horizontal position, neither of which present a problem for case fans because they are almost always positioned vertically and not exposed to excessive heat. Sleeve bearing – The cheapest and most popular type of bearing among case fans.Let us quickly go over the types of bearings that you will encounter with case fans: The Bearingįans utilize a variety of bearings based on their intended use and price range. You can also get some fan controllers to help you manage the speed. However, RPM is not a reliable way of estimating just how efficient a fan is, seeing as that depends much more on its size and design. And the question of whether high RPM or low RPM is better depends entirely on your needs and preferences.Įssentially, low RPM means less noise but also worse airflow. The SpeedĪ fan’s speed is measured in revolutions per minute – RPM for short. As you can see in the main table at the beginning of the article, case fans most commonly measure either 120mm, 140mm or 200mm in diameter, although there are other sizes, too.īut what is the best case fan size? While there is no definite answer, we would say: the bigger the better! This is because bigger fans enable better airflow as a result of not having to spin as fast as the smaller fans, which is something that also leads to lower noise levels.Īs such, we strongly advise you to go as big as your case allows to make sure that your money is well-spent. Let’s start with the most obvious characteristic of a case fan: its size. How To Choose The Best Case Fan For You The Size Furthermore, the lack of color variants does not help the matter. The only problem with it is that, while it will blend seamlessly with a white case, it may easily clash with some others due to the white fan blades. It is a highly durable rifle-bearing fan capable of reaching high speeds without producing an excessive amount of noise, all the while being remarkably cheap. There is no denying that the NZXT FN V2 is simply a great deal. It is a quiet and efficient fan that boasts a black-and-white design, a great representation of NZXT’s contrast-heavy design philosophy. However, anyone who has ever used an NZXT product can anticipate just how well-built the FN V2 fan is. Unlike any of the previous entries, NZXT may not be a name that everyone will recognize immediately. May not fit aesthetically with some cases.Moreover, while blue lighting is thematically understandable, some users may be left wanting for more variety. In contrast, this might put off some users who actually do not require that much power from their case fan and would prefer a quieter one instead. It is evident not only from the specs above but also from Thermaltake’s marketing and the fan’s very design, that this particular model does not sacrifice any efficiency for the sake of convenience. When it comes to visuals, the Pure 20 fan comes in two variants: a simple matte black exterior or a transparent one complemented with blue LED lighting. The design enables excellent airflow, although it is a tad noisier when compared to some competing models such as the Cooler Master MegaFlow 200. The Thermaltake Pure 20 fan is a large yet sleek and elegant case fan. ![]() And for their first entry, we’re starting big – literally. Needless to say, if you don’t care about RGB or don’t plan on fully utilizing its capabilities, simple LED lighting or no lighting whatsoever would be much more cost-effective.įinally, we get to yet another big name, Thermaltake. As you might have guessed, RGB is the primary reason for this. The hydraulic bearing plays a vital role in that regard but one can’t help but notice the hefty price tag. It is obvious that the LL series fans aren’t just for show, given how well they balance the high RPM with such low noise generation. Keep that in mind if you’re planning on a bulk purchase. However, their most distinguishing feature lies in the fact that they come with fully customizable RGB lighting.Ĭorsair is selling these fans in dual and triple-packs as well, the latter including a Lightning Node Pro as a bonus, something that RGB enthusiasts will undoubtedly find appealing. They are also hydraulic-bearing fans who do a remarkable job of finding a good balance between speed and noise levels. One look at these fans and it becomes ultimately clear that they will make any transparent case a sight to behold. And we have a true premium-quality fan – the Corsair LL Series LL120.
