Thanks for creating this thread as I'm sure many owners (like me) have ongoing problems with these supposedly multifunctional paperweights.

It's been a few months since I've turned on this miner and in the beginning it worked fine hashing at 1.6TH with temps in the range of 75-85C (core).
My troubles started when CTA1 started to report inconsistent temperatures usually +15-20C above CTA0 while ambient temps have not been changed.

Shortly after this anomaly CTA1 started to throttle very often. I have cleaned the original thermal paste and reapplied a known quality brand.
This seemed to fix the issue for several weeks and CTA1 was within 5C range and I was a happy miner (my overall temps have gone down considerably too).

Next I encountered the "dead core" cointerra disease, as half of CTA1 disappeared. I was reflashing and restarting this diabolic device multiple times and disconnected/reconnected all the connectors inside to resolve this issue.

Couple of weeks after I'm again seeing CTA1 throttling very often meanwhile the reported hashrate is 1.3-1.5TH (temps in the 80-95C range).

I'm thinking about ordering quality thermal pads due to the unevenness of the chips surface and using a proper wc loop ("luckily" I have spare parts - will report back when it's done).

Do any of you found a permanent fix or tried something else with success?

Whatever you do, do not buy these thermal pads ( http://www.frozencpu.com/products/16878/thr-164/Fujipoly_Extreme_System_Builder_Thermal_Pad_-_14_Sheet_-_150_x_100_x_05_-_Thermal_Conductivity_110_WmK.html?tl=g8c487s1730&id=T4zpcMmV ) I bought these and my temps got worse. Temps went straight to 105°+. There was a guy on the Cointerra forum that used Collaboratory Liquid Pro and said it brought his temps down.
