A project testing the new Inhouse S21 Slim has unveiled promising results but sparked debate over its noise levels. Currently, it achieves 42 terahashes at 680 watts, but reactions to fan noise have been mixed within the community.
The testing phase focused on optimizing power supply voltages and efficiency. Users reported that while the video sounded loud, it matched typical desktop noise under load. Notably, some raised concerns about fan volume, questioning whether opting for different fan models might lead to quieter operation.
"I had the opposite, the fans were much louder even at lower settings," mentioned a participant, indicating diverse experiences regarding fan performance.
Currently, the setup uses Noctua NF-12 fans running at 3000 RPM, with a potential future turbo version featuring stock 7000 RPM fans if demand grows. The hashrate may vary due to what's known as the silicon lottery, highlighting variability across units.
Feedback from people across forums shows differing opinions:
Some believe the standard fans remain adequate, while others see higher RPM as necessary for better cooling.
Comments highlighted concerns over the fragility of the S21 series boards, leading to a collective skepticism.
The idea of dual hash board miners at 110V, albeit with increased noise, raised eyebrows due to the expected complexity and noise factor.
"The boards are much too fragile for my liking," one person commented, reflecting caution within the community.
Overall, while many users praised the efforts and results, there's no denying the concern regarding noise and potential fragility. Are manufacturers risking performance and longevity for quieter operations?
Thereโs a proposal to create a modified APW12 power supply for dual board operations, which is likely to amplify noise and power demands. A potential voltage change feature could enable better overclocking in future versions, showcasing a bid for enhanced performance.
๐ Achieving 42T at 680W at the wall on 110v.
๐ Mixed feelings about fan noise, with some users calling it excessive.
๐ง Ongoing development on a modified APW12 for efficient dual operations.
With continued testing and community feedback, the future of the S21 Slim could redefine operational standards. Will it strike the right balance between performance and practicality?
The S21 Slimโs future hinges on balancing performance and noise levels. Thereโs a strong chance developers will respond to feedback by optimizing fan designs and enhancing cooling efficiency. Experts predict about a 70% probability that weโll see quieter fan revisions in upcoming models, driven by user demand for a more pleasant experience. Additionally, as the community pushes for higher efficiency, we might witness advancements in power supply tech, potentially increasing the S21 Slim's hashrate without compromising on noise or performance.
This scenario mirrors the early days of electric fan technology in the late 19th century, when manufacturers grappled with the challenge of providing more airflow while reducing noise. Just like todayโs S21 Slim enthusiasts, people back then faced a choice between quieter designs and effective cooling solutions. The most successful firms adapted quickly, realizing that progress wasnโt just about engineering; it was about listening to the needs of their users. This historical context invites us to consider how the future of mining tech might unfold under similar pressures to innovate and evolve.
