Today I added a Delta AFC1212DE which has 148cfm at 3900 rpm which is being run through molex so it's going full speed. I also have a second fan running in a pull configuration at 1800 rpm. But for some odd reason Row 1 is 58 degrees and row two is 44. There is A LOT of air being pushed and pulled through this miner, why is one side way hotter? Should I RMA? I've only been running it for 5 days. I should also add I'm running it at the stock 350 setting. So no overclocking. Also the temperature in the garage is 58 degrees Fahrenheit / 14 degrees Celsius.
EDIT 1: It has now started restarting mining every 7 minutes or so. It will be at 1Th then all of a sudden drop to 0 and then start to climb back up. There are no X's.
Nothing un-usual about the 58, 48 temp readings (mine has 44, 50 at night-time and up to 52, 59 day-time with just an S3 fan), but worrying in your instance are the restarts .... you need to get in touch with some-one directly at bitmain.
