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 reacted well to the mid-low frequencies, resulting in slightly higher values, but the unpleasant high frequencies have shown significant attenuation as expected, making it sound 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 m 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 measured 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 many HPC users over the past few years. Even with its simple fanless design, we have not received any reports of heat dissipation issues, so you can purchase with confidence. It is a best-seller that we can supply with assurance. We appreciate your continued support.

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 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 implementation, ensuring complete resolution of issues. We support overall planning by adequately preparing technologies from related specialized fields, not only addressing noise control but also calculating the compatibility of airflow and air conditioning power for the entire room. We offer valuable feedback as a common benefit to society free of 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 guidance on common mistakes that the general public tends to make, along with countermeasures and advice. The differences in numerical readings due to variations in volume, sound quality, and frequency distribution, as well as their relation to perceived loudness, are judgments based on experiential knowledge gained through specialized training, such as absolute pitch. This is a field of expertise for our company. Please feel free to make use of our services. *You can view detailed information through the related links.

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 100mm intervals in the catalog are for convenience, and we can accommodate any dimensions freely and individually. We will propose a suitable rack specification for each customer. It is our mission to solve the challenges of sound and heat from the supplier's responsibility, rather than having customers choose a rack that fits their size.
