Watercooled Case Gallery

It's the little things that you appreciate in life. Like stopping the petrol pump at a nice round number.

Afer a long service (10+ years) from my Corsair 900D I moved into a new O11D Evo XL home!

20251019-082411.jpg


Was a long process with a few challenges to overcome that I hadnt visualised when ordering fittings.

Had to buy a shorter Aquacomputer reservoir but fortunately you can buy just the tube as a replacement part. Replaced the 200mm one with a 150mm.

Migrated away from PETG to PMMA. Whilst PETG is super easy to work with it doesn't quite have the clarity and appearance PMMA gives...I do miss being able to use ratchet pipe cutters instead of sawing though!

The O11 was a joy to work with and has been very well thought out. The only thing I would have liked to have seen is openings in the top panels to access radiator ports to make bleeding easier. I did consider going to 420 rads (which the Evo XL supports) but I felt it was going to be far too tight, a cross flow 420 would likely not fit. As much as I would like to remove the support column where the glass meets, the upper radiator is far too heavy and causes some notable sag in the corner which Id rather avoid long term.

I've ordered some extra fittings and bits and bobs to rejig the fill/drain port location and I might move the flow meter also.

Have some more braided cables on order to make a better/easier job of the cable management in the rear chamber. (Hence no cable management pictures yet :o)

Loop spec:
EK Vector 5090FE Block
EK Velocity 2 CPU Block
EK Surface P360M rads (Top, Bottom)
EK Surface P360M X-Flow rad (Side)

Aquacomputer D5 Next, 150 Ultitube and Leakshield stack
Aquacomputer Octo (Fan management and sensor logic)
Aquacomputer Hubby7 (Never enough USB headers!)
Aquacomputer Hi Flow Next 2

Mostly Alphacool Eiszapfen Pro fittings
16/13 Acrylic hard tubing

Fans run off the Lian-Li controller with RPM set by Aquacomputer Octo logic in passthru mode.


Some more pictures below!

The outgoing 900D build, redundant 5.25" bays and all!

Old water cooling parts to flush new rads. The EK surface rads were actually rather clean. 2 of the 3 had almost no residue, 1 had a little more.

DIY 3D printed cable combs coming in handy.

Spending the time to be accurate, putting the laser level and calipers to good use :D

Hole spacing on the Aquacomputer Octo and Hubby were just right to use the SSD mounting kit in the O11

Lovely build, what's the temps like on idle and maxed out?

I'm still waiting for the Phantek NV9 distro plate to go on sale. All the other distro plates on the market tend to have the water flow in series, first cool the GPU, then the CPU. This method adds extra temp on the CPU. Phantek can cool both at the same time, kind of like dual cooling. My old Phantek distro plate did dual cooling, but it would use all of the back part of the case.

5090 never above 35 to 37 deg C.

7800X3D can get toasty when compiling shaders f.ex (circa 72 deg C) but then stablises around 55 ingame.

Water temp around 35 to 37 Deg C when fully saturated (5 to 12 deg c delta to ambient fluctuation normally but I need to tweak my fan curves in new build)

Using kryosheets on both for less maintenance so could arguably get better temps with a paste.

Results sound amazing, but your 5090 doesn't go over the temp of the water? I expect like +15c deltas with EK blocks at full load.

Beautiful build.

Nice temps, I also use the same maker as the kryosheets (Grizzly right?). My next build will have 360, 480 and 240 rads. This will serve a 5090 and a 14th gen Intel i9.

Yeah, couldn't agree more :D . That paste is a nightmare of a job to put on, but worth it in the end.
I've used the Kryosheet and just don't trust it to sit flush when I tighten the blocks down. They do work well when installed correctly.

Kryosheet is an absolute lifesaver for testing purpose though! No clean-up needed.

I am currently using either TG Kryo,Hydro or Duronaut paste with Duro being the option moving forward. Main problem is spreading thick paste. The trick is to put the tube in a cup of warm water before applying!
