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.

Hi,

I too had similar experience as quoted, however mine did not restart every 7 mins. When I first got my S5, it was working flawlessly for good 2 days. Then the hashing rate would gradually drop and eventually to 0 and restart. Its left at default freq of 350, temp was around 54 in the mornings and 56 highest during the day. Its powered by a CoolerMaster v1000 PSU which is running cool all day.

I turned it off for 5 mins and started again but after running around 30 mins or so it will happen again. I have another 2 units of C1 running 24/7 which does not seems to have any problem, so I guess that rules out the internet connection possibility. I inspected the blades but could not find any burned or damages. The time it takes to enter the reboot cycle is not consistant, at times it happens in a few minutes or sometimes a few hours. I got my S5 via the DHGATE link at Bitmain's site together with a friend and he too has the same problem. Currently to get stability, we ran the freq at 300 and 325 respectively.

Any ideas?

Thanks.

Please can you try and take a screenshot of the S5's status page when you're getting degraded performance? What firmware version are you on - it should look like a date.

How can I tell what firmware version I have now? - Navigate to System -> Overview and look at "File System Version".
