Your pump speeds are reporting zero RPM which means the LCA's have failed. You have to replace the LCA units. I have a few extra if you're interested you can PM me
Ah, I missed that. Yeah, that could be the issue. The hashing boards won't power up the ASICs if the pump speed is reporting 0. LCA = liquid cooling apparatus, pretty sure

So I believe both boards in one system are having PMBUS faults.

For anyone interested, here is a nice little demo of how 3M uses the Cointerra boards/chips to demonstrate 2-phase immersion cooling. Video from 3M booth at Supercomputing 2015 (SC15) in Austin: https://www.youtube.com/watch?v=a_vJbGgxPTUCointerra chips have been overclocked to 750W this way (instead of 500W each), but not specifically in this demo as far as I can tell. Interesting to see the Cointerra boards being used by supercomputing folks to see what would be possible if chips would be a tad bit larger than what they are used to and cooling would be different than what we use today (air, water, chillers, etc).

on the 3M video, what do they have covering the chips???
I thought I was going to see the bare chips. It looks like they still have to use some form of a heatsink to help remove the heat from those power suckers.

its some form of heat spreader. the novec can carry away a certain amount of heat per sq cm, and for anything hotter you have to increase its surface area to give the novec the chance to do its job. I've seen heat spreaders that have pin cushions on them before. the way the heat spreader is attached is also tricky, as the liquid would dissolve the usual forms of thermal paste, so you have to use something that sticks even in liquid.

I realize my answer comes a bit late, but I would not buy that water block. For 2 reasons, and before I give them let me say I have a couple of those and have used one on a Hashfast board... 1. You can get that block cheaper on Ebay 2. and more important, you want blocks that have G1/4 fittings. This is the industry standard basically for computer water cooling. Almost all gear you look at will be G1/4 so using this and only this will assure you are always compatible.

Is there any news about Terraminer overclocking? Maybe some patched file to get higher frequency of PLL?
Regards.

No, unfortunately not. I think at this point, most (if not all) Cointerra miners have been smashed, ground up, and melted down to create new cars with. They are pretty much useless at this point as they use way too much power for what little hashrate you get out of them. Even with the BitCoin price at record highs right now, I don't think that a Cointerra machine could be profitable to run. I still have one Cointerra machine in my basement right now, but it hasn't run since about 2015 and I gave up trying to work on it a long time ago, lol... I sunk way too much time and money into trying to keep my Cointerra miners working for as long as possible when it would have been much more sensible to have abandoned them long ago and just upgraded to newer mining hardware.
I recently upgraded my whole mining farm to AntMiner S9's and decommissioned all of my old miners and have never looked back. I'm getting much better and more stable hashrates and I'm pulling down the best revenues that I ever have since I started mining BitCoin. I sold off several of my old AntMiner S5's already as well as one of my Cointerra's and a Spondoolies SP31 I had. All I have left right now is one broken Cointerra for parts (that won't mine at all anymore) and a couple of parts AntMiner S5's (that each of them had one of the hashing boards stop working for some reason).
If anyone wants any of these miners to play with or to scavenge parts off of to keep their other miners going, let me know and you can have them!

Wow I think you just saved me $100. Are they really that bad of a unit?
I was just about to pull the trigger on a used Cointerra Terraminer in Toronto that had some cooling pump issues. I love to tinker with electronics and mechanicals so I thought it might be a nice challenge with the possibility of getting a miner in the end. I currently just hobby GPU mine and was looking for some cheap asic equip to get my feet wet on and that i can run off my wind generator as the power is semi free and not used when i'm not in the garage. I also found an ad for a cheap used gridseed g-blade scrypt miner but from what i read they are just as bad or worse and not useful for anything anymore. Any recommendation on what used hardware i should be looking at just to play around with?
Thanks
