Title: My installation can hold 2 antminer S9 or more ? Post by: rotem8866 on December 11, 2017, 06:24:49 PM Hi all
im running new antminer s9 from today , and expecting to the second one. i build some silence box with proper intake but im not so sure about the exhaust. After running the s9 6 hours , i got 75 - 80c but the box where i hold the miner is pretty hot and im worried to connect the second miner when its come. I attached sketch of my box , im using 6 INCH Blower with those specs : power: 40W voltage: AC220V frequency: 50Hz color: white rotating speed: 2800rpm https://imgur.com/a/IXPxr I wonder if the blower strong and fast enough to remove properly the hot air (negative pressure ???) What is the optimal exhaust for 2 antminer s9 with duct pipe for 2-3 meters ? THanks and sorry for my english Title: Re: My installation can hold 2 antminer S9 or more ?

Post by: philipma1957 on December 11, 2017, 09:24:54 PM you can not do 2 s-9's with that setup. 2 s-9's need a 10 inch duct and this fan https://www.ebay.com/itm/Comair-Rotron-CLE2T2-10-455-CFM-1400RPM-Caravel-AC-Cooling-Axial-Fan-020189/132400954128? pie r 2 so your six inch is 3.16 x 3 x 3 = 28 square inches the s-9 are 3.16 x 2.5 x 2.5 = 19.75 sq inches x 2 = 40 square inches the fans are super fast you can not get 40 square inches to squeeze into 28 square inches and you have 10 feet length which adds to the problem. found this 8 inch on eBay https://www.ebay.com/itm/4-6-8-Inch-Duct-Booster-Inline-Blower-Fan-Blower-Exhaust-Ducting-Cooling-Vent/111809922919? 8" Booster Fan Spec: Duct Fan 8" Spec Air Flow - 420 CFM Duct Size - 8": Decibels - 30 (+/- 1.5) Duct Fan 8" Specs Material - Plastic Fan energy efficient and very quiet; Power - 46 W ; Input Voltage - AC 110v/60Hz 7 ½' length of wire cord it is a 120 volt but moves 420 cfm 1 s-9 moves 200 cfm six inch will do up to 230 or 240 maybe an 8 inch will work as it says it does 420 cfm |
