Title: Overclocking using Airflow into Mining Room? Post by: ReadyPlayer1 on May 02, 2018, 02:17:54 PM I have a 10 x 11 room where I have about 27 antminers. I've created a hot/cold aisle using a heavy duty tarp. I have (4) 3,000 cfm gable fans for intake and exhaust. 2 fans on the cold side and 2 on the exhaust side (along with a 450 cfm exhaust fan on the very top of the room for excess heat). I also have (2) 14,000 BTU AC units on the cold side too.
Are there downsides to having the (2) 3,000 cfm intake gable fans blowing directly onto miners from about 3-4 feet away? I've noticed the miners perform very well in this setup and temps are good. I'm afraid though that with all the air blowing onto the miner intake fans that it will burn them out or damage them, etc. I basically feel like I'm overclocking them with the air inflow but not sure. Does anyone have any experience or thoughts on this? http://i68.tinypic.com/15nrm9j.jpg http://i68.tinypic.com/687rmh.jpg http://i67.tinypic.com/2qmlqn9.jpg http://i65.tinypic.com/10hkgwl.jpg Title: Re: Overclocking using Airflow into Mining Room?

Anyone? Title: Re: Overclocking using Airflow into Mining Room? Post by: tim-bc on May 07, 2018, 02:29:03 PM I have seen similar setups and I would say there is no downsides to having those fans blowing straight towards the miner intake fans. Typically I have seen the gable fans all used on the hot side for exhausting hot air, but it should work the way you have it too.

Also, why are you running air conditioning? You are using the least efficient AC units possible, those semi portable types. Do they even run on 220? You really need to look into a better cooling solution, AC is not the way to do it. I wouldnt blow intake fans right onto the miners, just because the air turbulence can cause those front fans to die faster than normal. Title: Re: Overclocking using Airflow into Mining Room?
