$9400 Aventum X effectively dead after 5 days

I'm very sorry for your situation, Mario3504. This is indeed a very serious situation, and you must call DS tech support ASAP. When talking with them, might be good to share pictures of the system as is, system specs (e.g., Motherboard, CPU, etc); picture of the reservoir level. Do not turn it on unless DS says otherwise.

Many folks in the forums have purchased hard line tubing in the past and commented on the fact that tube leaks are not uncommon. The system gets jostled somewhat during the shipping and handling process. Fittings may look tight, but if the gaskets have failed as a result of the jostling stress, tightening fittings won't help.

It doesn't look like you had thermal issues associated with inadequate coolant supply to components. Not certain, but you should be OK from a motherboard short due to coolant getting on the board itself. An internet search finds other examples of Qcode 97 related to inadequate mounnting of CPU and/or GPU blocks. Again, consistent with shipping and handling.

The fact you used the machine for 5 days without issue asks the question what did you do differently on the last day? Were you stressing the system (heavy CPU/GPU usage) such that increased cooling capacity was needed?

Good luck. I really hope you can get this sorted out. The Aventum X is a fantastic machine.

I have spent a good amount of time here over several years. I so feel for you.   

In all my time, must be thousands of systems have shipped with hard line tubing, but only a scant 2-3 dozen have been reported here, and very few with what seems to be a wide-spead failure. Nevertheless, I will never recommend any custom loop cooling system. For me, what has happened would be just about the worst outcome I could imagine from what I always hope will be a joyful experience for all you folks. The ongoing care and maintenance would bug me, too.

I'm not trying to make things worse, I'm just trying to say that one of the more experienced members here is in full empathy with you. My experience is that Digital Storm will attempt to move "heaven and earth" to help you with this, but it doesn't seem it'll be an easy fix.

You didn't make a fatal mistake, you just got royally messed with, and I'm sorry. "This, too shall pass", so may the Force be with you.
