The shooting was conducted under severe conditions with room temperature exceeding 30 degrees. The noise attenuation varies by plus or minus 5 dB depending on the rack size and the combination with the machine. In this case, the noise meter responded well to the mid-low frequencies, resulting in slightly higher values, but the unpleasant high frequencies showed significant attenuation as expected, making the auditory experience very good. The sales representative present remarked, "Sufficient performance! I was surprised by the noticeable difference." 【Overview】 ■ Measurement date: August 26, 2021 ■ Measurement location: Si R&D measurement room (background noise below 29 dB) ■ Silent rack: Si R&D S8.0ZR-12U modular assembly ■ Machine: Visual Technology VT64 XS2-2TI ■ Measuring instrument: AR814 ■ Measurement position: 1 meter in front of the rack, height 70 cm

We attempted noise measurement with the fanless silent box 'dBP07V-7048grtr' using an actual machine. The machine provided by HPC Tech is the "WRSX32-4GP." The noise level alone is 69dB, and when housed in the silent box, it is 67dB, with a noise reduction down to 41dB, which can be heard in the video. Additionally, this product has accumulated a track record of supplying numerous HPC users over the past few years. We have not received any reports of heat dissipation issues, even with the simple fanless design, so you can purchase with confidence. It is a bestseller that we can supply with assurance. We appreciate your continued use of our product.

We offer soundproofing construction specifically for HPC servers. Soundproofing for HPC involves specialized acoustic treatments tailored to unique noise sources, as well as technology products that cover requirements for machine heat dissipation and air conditioning compatibility. We will develop individual proposals for each customer to ensure maximum implementation results.

This is the time of year when inquiries about heat dissipation increase. Since there is a span from the formulation of solutions to delivery, we recommend contacting us early. At Si R&D, we provide tailored rack specifications based on machine configurations and offer advice on installation conditions that can impact the results of the implementation, ensuring complete resolution of issues. We support overall planning by not only addressing noise control but also calculating the compatibility of airflow and air conditioning power for the entire room, utilizing expertise from related fields. We provide valuable feedback as a common benefit to society at no charge. Please take advantage of our strengths and advantages. We look forward to your inquiries. *For more details, please refer to the related links. Feel free to contact us for more information.

There are many instances of incorrect usage of sound level meters in various situations. We will provide information on common mistakes that the general public tends to make, along with countermeasures and advice. The differences in values due to variations in volume, sound quality, and frequency distribution, as well as their relation to sensory perception, are determined by experiential judgment from specialized training, such as absolute pitch. This is a field of expertise for our company. Please feel free to utilize our services. *For more detailed information, you can view it through the related links. If you have any questions, please do not hesitate to contact us.

The "Silent Rack S4.5ZR" is listed in the catalog starting from the 6U size. The height of 6U is 478mm, making it a limited specification for special applications with height restrictions (such as under a desk). For reference, the height increments of 3U and the depth specifications at every 100mm in the catalog are for convenience, and we can accommodate any dimensions flexibly and individually. We will propose the most suitable rack specifications for each customer. Our mission is not for customers to choose a "rack that fits their size," but to solve issues related to sound and heat as our responsibility on the supply side.
