Heat was my guess,
But my first Antminer Rig was running for a couple days at 375MHz , avg temp 48... and was doing fine.
Do you think an average of 48 is okay?
I would also like to mention that i lay my antminer diagonally on a slanted shoe rack, plenty of ventilation.. Could this be trapping concentrated heat for any reason?
I guess adding the second ant has increased the ambient temp in the room, making it run hotter in there. I suppose 48 is ok, but PWM usually tries to keep it around 40, so that would be my ideal temp to go for. The temps are also not evenly distributed across the boards and the back end will be a lot hotter than the sensor measures and that's probably where the X's are coming from.
I'd also put something solid underneath the unit so that the air is directed all the way across the heatsinks and isn't lost blowing downwards through the slats, it could help a little.
Best thing is to get some extra fans to help with the cooling.
Thank you for your input! Very Helpful =)
I placed the Antminer on a piece of Styrofoam type material... (Styrofoam doesn't conduct heat)
It has lowered the temperature to about 48 AVG.
I also notice that the fan on this one is 2340.. While my other 2 are 2040 and 1980, Since these are all different numbers, I am assuming that the speed of the fan can be adjusted via config???
*I would also like to add that my fans are blowing upwards in a diagonal position
