Hi, I have an Antminer S9 and due to the extreme noise it makes, I put it inside a box with two pipes for each fan. Each pipe has acoustic fiber for noise reduction, however the S9 gets very hot (up to 113 ºC) and the red light next to the ethernet port starts blinking and it stops hashing.
So, I was wondering if I apply cold air (I'm planning to build a cooler) the fans would run slower (and less noisy) ?
Thanks
It looks like your "pipes" are blocking a lot of airflow. What's the temperature in your room?
I've used these quite successfully:
