No I did not get a better hash rate. The terraminers are designed to run at 1.6Ths regardless of temp until a core hits 120c then it reboots. I also noticed my miners would have one or two cores that where significantly hotter then the rest. I opened my last 3rd machine to cool it and noticed that many of the screws that hold down the cooling block where not even screwed in or they where barley screwed in leaving the cooling block lifted up and not having good contact to the core. Another fail by cointerra. Only apply the LiquidPro to the cores, not the cooling block. Just like the photos I posted.

FYI, my third machine when put back and turned on failed to boot up CTA1. Ive cleaned the board twice but still no mining. It has power but does not boot up and coming online so currently only CTA0 is mining. I will most likely pull this board again and give it a full bath in a last desperate attempt. I was so critical in doing this last cooling job just because of my previous experiences and still I fucked up with no idea how.

If you decide to open clean and cool with LiquidPro its a huge risk but if you can pull it off its well worth it

Hey Scriber how would you go about giving a "full bath" to the board? do you wash it with alcohol or something else? I'm asking because i'm in the same boat as you, I reapplied the thermal compound and now one board does not want to work. CTA0 is working but CTA1 powers up but does not do anything. I've looked at the board all over and don't see anything wrong with the board so i'm willing to trying just about anything to get it working again.
