You want to buy a new chassis, and you wonder about its noise output? Our latest project offers the solution.We started with power supplies, and since we have the experience and the proper equipment, we thought to help users find the most suitable products for them in other categories as well. One of the most popular is the chassis (AKA cases or enclosures) one. Along with power supplies, enclosures belong to among the essential parts since you keep them for many years, and most of us use them through several system upgrades. This is why it is of immense importance besides high ergonomics, to also have the best possible sound dampening performance which can also affect its thermal performance and vice versa.
In our Chassis Noise Level database, you will find all of our chassis evaluations. We conduct all of our measurements at 23-26 degrees Celsius ambient using lab-grade equipment and a hemi-anechoic chamber, with lower than 6 dB(A) noise floor. We focus on the noise dampening performance of each chassis, which in layman's terms is to what degree the chassis lowers the noise that the system generates. Besides the noise dampening performance, we also include the speed and the noise output of the chassis' stock fan(s).
In the database mentioned above you will find results that describe the number of the stock fans, the noise dampening performance, the noise of the stock fans at three different speeds (100%, 75%, and 50%) and the stock fan speed at three noise sound levels (35/30/25 dB[A]) if those can be achieved. You see, besides measuring the noise at some fixed fan speeds, we also do the opposite. We set the fan(s) speed at some specific levels to achieve the desired noise output. This way, it is easier to compare (and much more accurate) the thermal performance of all chassis under the same conditions. For the moment, we don't include thermal performance results in our database, but this doesn't mean that the interest users or reviewers cannot use our findings to make their comparisons and draw safe conclusions. You see, comparing the thermal performance of the same system in two different chassis with not the same fan speeds is something that won't tell you much. But if you make both chassis operate at the same conditions, under which they deliver the same noise output, it makes it much easier to find the best performer when it comes to the handling of heat loads.
Once we have enough results and the required amount of data to build a solid standard, we will start taxing the chassis in LAMDA categories, providing the corresponding noise certifications. So shortly, hopefully, you will be able to get a LAMBDA-A++ power supply and match it with a similar LAMBDA level chassis to build a dead silent PC system.
