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.

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.
