I contacted their sales team in January 2020 and Tomasz Buk was their lead sales person. We had contacted by email about the enclosure I needed for my 8 Whatsminer M20S miners. My total cost was about $6000 landed. I purchased it, wired them the money and waited. Initially I was told a month at the most to arrive at my door but it ended up being 2 months, which was ok. The enclosure arrived on a crate with everything I purchased. I set it up using their youtube guide to everything exact, problems that occurred: 1-Leaking issues at the two output and input pipes, which took me two days to fix.
2-The fan and copper radiator system cannot cool the liquid in the box down fast enough. Every 5 seconds, it increased of 0.1 celcius until it reached 75C where my miners are overheating and shuts off. I contacted Tomasz about this issue and was directed to Maciek Szadkowski, whom was the CTO at DCX. Maciek was the main person created the enclosure to sell to the public, he emailed me back and asked me to contact him on Whatsapp so he could assist me to resolve my overheating issue, instructed me to take all the pictures and tell him all the temperature of the place I put my miner setup in, which was my garage at 25C, I also bought a AC unit blowing 15C directly towards the fans to try to cool the liquid down faster but it still didn’t work.
He wanted me to try to move my miners around in the enclosure in a different pattern, which didn’t work. Then days later, he wanted me to try a different direction, which also didn’t work. I tried everything he asked, to at this point I’m wondering if this enclosure even works at all, if it works then why would he want me to try this and try that? Then he wanted me to put my fan/radiator outside of the garage, which was 37C-40C outside instead of 25C inside, because he said outside temp, even though 37C in the hot sun would cool the unit down better than inside the garage which was 25C, which absolutely made no friggin sense whatsoever. I was only able to get 1 of my miner working in the enclosure at 45-50C constant temp, with a separate AC unit blowing 15C freezing air at the radiator, if I put in 2 or more, it wasn’t able to cool it down fast enough, it’ll reach 75+C in 20-30 mins and all my miners shut down automatically due to extreme heat.
After talking to him back and forth for days trying to resolve this issue, I asked him if they have any proof of concept of it working properly? He said nope. So they basically created this enclosure not even knowing that it’ll work, Maciek just says it works but they don’t have any proof of it working. I asked them to make me a video of them putting miners into their enclosure and showing me the temp proving their system works, Maciek said he’ll do it next week. A week went by, I text him to see how it’s going with the proof video, he saw my message but didn’t reply, so I text him a couple of days later and still, no reply and now he’s ignoring me without any replies.
Conclusion: They are selling Liquid Cooling Enclosures for Miners that supports 8 miners in their enclosures without any PROOF that it works at all. We are the BETA testers for them, costing me $6000 to BETA test for them. I don’t know what to do at this point, I’m extremely devastated by this, I wired $6000 to them and I don’t know who to contact to get my money back or at least half of it. Anybody out there know how to deal with this problem, please let me know. This is a message to all those trying to buy an enclosure from these DCX people, they don’t have any proof this thing even works. They are scammers, beware.
