Say goodbye to outdated and inefficient mining equipment and embrace this state-of-the-art solution that combines functionality and aesthetics. Investing in the ASIC silencer box 40 is a wise choice for any cryptocurrency enthusiast. Not only does it provide a peaceful mining experience, it also helps maintain harmony in your home. Say goodbye to noise complaints and welcome a new era of hassle-free home mining. https:\/\/www.youtube.com\/watch?v=iYOptDBmRQE Reducing the noise of your S19 ASIC from 80 dB to 36 dB When developing our soundproof box, we focused on using only materials that are environmentally friendly and do not produce any harmful emissions or unpleasant odors. We deliberately avoided the use of mineral wool as a soundproofing material. Thanks to its weight (around 50 kg), our soundproof box can effectively suppress noise in a wide frequency range. This includes not only high frequencies such as whistling, but also noises with a frequency below 1500 Hz. Our product is suitable for all types of ASICs and differs only in the equipment that allows a specific model of ASIC to be placed inside the box. If you decide to change the ASIC model in the future, it is not necessary to change the entire box, which ensures the flexibility of our device.\u003cimg src=\"https:\/\/pcpraha.cz\/wp-content\/uploads\/2023\/06\/antihlukova-bedna-anti-antminer5.jpg\"\u003e \u003cstrong\u003eHow does a soundproof box work?\u003c\/strong\u003e In addition to performance and efficiency, we also paid attention to comfort. Our muffler is comfortable and easy to maintain. The outlet of hot air is oriented vertically, which allows a comfortable position close to the box. This is one of the main advantages over most simple mufflers with horizontal hot air exhaust. Our product guarantees high efficiency in noise suppression without damaging the ASIC. Thanks to the isolation of the cold and hot zones, excessive heating of the chips does not occur. The fans are not overloaded and the ASIC is placed on a vibration pad, extending their life. We also offer a ripple adapter for heat dissipation, and a double box can be used for more powerful ASICs with a total power of up to 5 kW. For example, the most powerful and overclocked ASIC for a double box has a power of 4 kW. \u003cimg src=\"https:\/\/pcpraha.cz\/wp-content\/uploads\/2023\/06\/antihlukova-bedna-anti-antminer7.jpg\"\u003e \u003cimg src=\"https:\/\/pcpraha.cz\/wp-content\/uploads\/2023\/06\/antihlukova-bedna-anti-antminer6.jpg\"\u003e \u003cimg src=\"https:\/\/pcpraha.cz\/wp-content\/uploads\/2023\/06\/antihlukova-bedna-anti-antminer8.jpg\"\u003e","brand":"Pcpraha","offers":[{"title":"Default Title","offer_id":49002911498568,"sku":null,"price":752.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0843\/5479\/3800\/files\/antihlukova-bedna-anti-antminer6.jpg?v=1725528596"},{"product_id":"anti-noise-box-antminer-cryptomining-at-home-black","title":"Anti-Noise Box: The Ultimate Solution for Quiet Home Cryptocurrency Mining","description":"\u003cp\u003esay goodbye to the unbearable noise of miners with the \u003cstrong\u003eASIC Silencer Box \u003c\/strong\u003e, the revolutionary anti-noise box designed specifically for home cryptocurrency mining.

Case airflow moves air through the case; a passive accelerator needs air forced through a narrow finned tunnel against real static pressure. Those are different jobs. Builders who skip the duct report the card idling fine and then collapsing under the first sustained load — which is exactly the load you bought it for.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eIs one fan really enough for three cards?\u003c\/summary\u003e\u003cp\u003eIt is, because the plenum is sealed and the fan is rated far beyond a normal case fan — 2.7 A and 6,000 RPM exists precisely to push against three heatsinks of fin resistance. You will run it higher on the curve than a one- or two-card build, around 2,500–3,500 RPM under sustained load.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eIs it loud?\u003c\/summary\u003e\u003cp\u003eUnder full three-card load, yes — noticeably.

A 1,200–1,600 W supply with enough spare PCIe outputs to feed three converters is the sensible bracket.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDo you have a four-card version?\u003c\/summary\u003e\u003cp\u003eYes — a dual-fan, full-board manifold built specifically for the Huananzhi H12D-8D, which also ducts air over the chipset and the board's three M.2 drives.
