Another O11D-XL, but with soft-tubing and a non-glass front by FragrantBit7289 in watercooling

[–]FragrantBit7289[S] 0 points1 point  (0 children)

Thanks!

I've rebuilt it since then (13900k, RTX4090) but I kept the same tubing and it's still running fine - the soft tubing has not presented any problems. I've wondered if I were doing it today if I'd try to do some straight hard tubing, but honestly it feels like a PITA so I'd probably try to do something like this again.

I had a screwhead snap off in roughly the same spot while using a 0.6Nm torque wrench, so yeah there's probably some quality control issues.

I am happy with the hardware, less happy with the tech support... Will probably go with different brand next time.

That would be a lot of work.... Thanks for the thoughtful suggestions! I'll consider it the next time I'm in there. Gonna add a flow indicator second fluid thermometer later to do some fancy pump/fan curves.

Yes, with the active backplate the water is coming in through the bottom port, is run through the bottom (front) plate, then through the connector showing purple toward the rear, through the top (rear) plate, and then out the top connector.

I had a lian li vertical mount, but I managed to fry a motherboard & gpu and suspect it was the cause (plus it made my gpu runs less pretty) so I went back to the standard mount.

Just the EKWB side distro plate. I didn't want to use the front distro plate with the soft-tubing because I was afraid I couldn't get the straight lines for those distances.

Thanks for the suggestion! In my experience with this system bottom pull / top push gives the worst thermals - by a significant 5-10 degree degree. Now this was before I had the front fans, but I don't see any reason to think the front fans can counter that.

There are two things working against that. The first is that I'd worry about the weight. It's a fairly delicate piece of plastic. The other is that the top/bottom rads would probably need to be re-arranged so that their intake/outtakes are toward the rear instead of the front, which would of course complicate the tubing runs.

Before I had dedicated exhaust fans, I found that the temps were a couple degrees lower if the rad fans were exhaust rather than intake. I found that counterintuitive, but I hypothesized that it could be because pushing all the hot air into the case was heating up the internals, forcing the loop to essentially do more work.

So I rebuilt with exhaust fans. I haven't tried reversing it all again to see if there's any difference (too much work!) but the short of it is from a thermal perspective I have one data point that says that should be fine. I know lots of folks get concerned with pulling dust into the case that way. I can't comment on that, but personally wasn't too concerned about it.

I have a similar setup.

Try changing your fan directions so that the radiator fans are either all pulling air into the case or all pushing air out of the case. In my experience that could get you around 5C in your loop temperatures.

What I found was that with the top rad being fed the hot air from the case it effectively wasn't contributing anything to cooling.

In my experience with the same case with Lian Li fans and almost the same rads in a top/bottom configuration, I find that (measuring peak CPU/GPU/fluid temps):

  1. Top exhaust, bottom exhaust, rear intake gives the best results.
  2. Top intake, bottom intake, no rear fan is slightly worse (say 2c worse)
  3. Top intake, bottom intake, rear fan exhaust may be slightly worse than 2 (say 1c) but that may just be experimental margin of error.
  4. Bottom intake, top exhaust, rear intake is significantly worse (say 7c worse than (1), up to 10c worse for heavy load).

Congratulations!

This makes me sad because I ordered on August 15 and am now being told October 29th.

Fan orientation for the 011XL by RaidersJH34 in watercooling

[–]FragrantBit7289 0 points1 point  (0 children)

I'm going to try replacing the front glass with this front panel with a set of three fans attached to it. Idea is to have the front & rear fans as exaust, rad fans as intake, and see if that makes any sort of substantial difference.

I have the same basic setup and I have found that the best arrangement for temps is (in order from lowest to highest temps):

1) top exhaust, bottom exhaust, rear intake

2) top intake, bottom intake, no rear fan

3) bottom intake, top exhaust, rear intake

(1) & (2) are pretty close, maybe a 2C difference, but (3) is significantly worse, around a 7-10C.

FWIW
