I just received my brand spanking new Aventum 3! It was a long wait, but the machine is beautiful, definitely worth the wait. The mobo side of the system look incredible, but when I turned it around, I noticed something was missing.

See if you can spot it:


Yeah, that big fancy custom waterblock isn't there I know it won't affect how the system runs, and that hardline tubing is well done, but I won't lie and say I'm not disappointed.

Awesome Congratulations on getting that beast and in red! Strong

As to the missing distribution manifold waterblock, some people here with that model have had it crack with coolant making a mess of things.  Enjoy.Big%20Smile

I like it better without the water block, both visually and functionally.   It’s cleaner looking and easier to work on if needed.    

No more cracked block.

Enjoy.

To quote today's game developers..."It's not a bug, it's a feature!"....

Enjoy that beast.

i was an early adopter of the Aventum 3.  I got a leak from the manifold due to the micro fractures reported around this time last year and had to have it replaced with the acrylic tubing like your setup. 

i hate to report that i just got another leak in this REPLACEMENT workaround and have an email in to Alex about it.  i suspect that a combo of heat and back pressure has caused the acrylic in some of the tubes on the rear to micro fracture as well.  i was assured back pressure wouldn't be an issue with tubing of this diameter, but...

i've been playing a lot of Inquisitor Martyr since it released on June 6 and it really pushes the hardware at 1440p/max graphics.  anyway, i noticed my fans on the 480mm rad stopped spinning today and the temps rose and game crashed.  i saw the liquid level in the res had dropped to about 2/3rds full.  i opened her up and saw coolant leaking on the back side from multiple points: elbow fittings, the tubes/fittings that lead directly into the back side bottom rad, etc.  possibly even the acrylic tubing itself.  i've heard with heat and pressure micro fractures can develop in sub par tubing.  i seriously doubt i've had multiple o-ring failure on parts installed less than 1 year ago. 

in any case, i hope you don't have leak probs like i've had with this rig.  i'll let you know how it goes with Alex.

i checked HW Monitor and my cpu temps highest was 82C and my gpu temps got up to 73C.  if the acrylic tubing temps got that hot then they could've warped.  i know when you do the bends with the heat gun you can start bending at 60C+.  if they're warped and no longer getting a good seal i'm gonna have to replace the tubing. 

does any1 know if they're using acrylic or PETG for their hardline tubing?  PETG has a lower heat threshold for bending.

@db188,

I'm sorry to hear about the leak issue, I responded to your email, once I get some photos me and the team will review and find the right solution for you.

Your fluid/tubing will never be as hot as the actual components. I haven't seen fluid get hot enough to bend tubing (PETG or Acrylic).

It will be interesting for us to see what is occurring if it's over time, they could be a failing o-ring or tubing that has been slowly pushing away with built up pressure over time.

thanks for the immediate response Alex.  i sent you some photos via my phone after the email i sent you yesterday.  can you confirm if you received them?

i'll send some more.  i've been investigating the internet for PETG deformation and (taken with a grain of salt) i found a lot of discussion about it deforming over time with even modest heat (60C or more) if the pc is used over extended time at more than idle speed.  i typically have my pc on all day, although i shut it down when i go to sleep.  i also tend to use it for long periods of time under load. 

the DS fan controlled software temp displays have always been suspect to me, so i back it up with HWMonitor (which doesn't read the liquid temp).  i typically have the fan profile set to "auto" so the bottom 480mm rad fans only spin up when needed. 

although PETG has a higher melting point than acrylic, it's deformation point is much lower  (why people like to work with it as it's much easier to bend).  all it takes to loose a good seal is a little deformation at the fitting/o-ring. 

i finger-tight tested the fittings and couldn't find an obvious loose one.  the top most tubing is a definite leak, and i'm not sure about the others in descending order.  the very bottom fittings going into the top of the rear 280mm rad are also suspect.

ok sent you some more pics/info. 

here's a photo of what looks like a crack in the distribution block where the left fitting screws in:




@OP-sorry for hijacking your thread, but since you own one of these i thought it might be educational for you to see what problems can arise.

leak fixed!  great job by Alex making the arrangements for service, and great service from John Sweger and his guysAwesome

they even threw in a high bandwidth bridge for my SLI 980ti's after noticing i didn't have one free of charge. 

the new distribution block has a metal plate where the fittings insert into so that should add some extra stability to the block.  DS takes care of their customers, folksCool
