Title: Regarding airflow for the Antminer S17 Post by: addalol on January 12, 2020, 07:36:57 PM Hello,
Im wondering if anyone know how much air a Antminer S17 pulls/moves, I know it is relative to fan rpm but Im struggling to find anything online about it. If anyone have a guide or something to how i could calculate it, would be greatly appreciated. I just started asic mining and im planing on making a soundproofed box to control the noise, need to know how much qubic meters it displaces to calculate what dimensions I need on an exhaust fan.

2 fans for psu. the hash board fans move at least 200 cfm each but they are pointed trough the hashboards so it is not 4 x 200 = 800 more like 2 x 225 = 450 tack on 50 for the psu fans you get to 500 cfm I feel that 500 cfm is pretty close to the top number they can do Why not do a 500 cfm a 550 cfm a 600 cfm set of calculations it will give you 3 box sizes to choose from.

i also build some boxes for my T17 miners. i only place the miner in the middle and make sure the output air cant get back to the input fans of the miner. the two fans on the back of the miner are enough to pull the air out of the box through elastic tube out of the window. https://ibb.co/1sSLr4M Title: Re: Regarding airflow for the Antminer S17 Post by: philipma1957 on February 05, 2020, 12:45:32 PM you may or may not get that to work.
it may not need help for exhaust or it may need it. the length of the tube leaving the box out the window is very important. the ambient room temperature of input air is important. Ie 3 boxes like your photo in a 0c (32f) garage would be fine even if the tubes to the window are more then 6 feet but 3 boxes like your photo in a 30c (86f) garage would most likely over heat without help to pull air through the tube also size of tube matters 10 inch size for 1 t17 should be good with no help 5 inch size too small needs a helping fan. inside of tube is important ie great tube for air flow due to size and inside shape allow for easy air flow https://pvcpipesupplies.com/pvc-pipe/pvc-schedule-40-pipe?pipesize=480 not so great tube due to size and inside shape it resists air flow https://www.homedepot.com/p/Master-Flow-6-in-x-25-ft-Insulated-Flexible-Duct-R6-Silver-Jacket-F6IFD6X300/100396935 here is a compromise tube https://www.homedepot.com/p/Master-Flow-Mobile-Home-12-in-x-25-ft-Insulated-Flexible-Duct-R4-2-Black-Jacket-MIF12X300/202191788 nice and big so it does not restrict air flow that much in all cases above longer tube may trap heat without some fan help lastly a tube that points upward to the window gets help from the hot air rises rule (convection). |
