Glad to be of help.
Good to know the full size 92mm fan makes a difference, that was the only upgrade I was considering in the foreseeable future.
Your undervolting seems good, make sure you are still getting the same performance though. I checked mine with Time Spy. Here are a few of my numbers for your reference:
| Chip Frequency(MHz) | VRAM Frequency Offset(MHz) | Voltage(mV) | TimeSpy GPU Score |
|---|---|---|---|
| 1950 | 0 | 950 | 13312 |
| 2050 | +800 | 950 | 13626 |
| 1965 | +850 | 893 | 14127 |
Thanks for your findings. So the fan under the PSU is better as exhaust than intake? Did you use the original feet? I think a small tweak would be adding slightly higher feet 2-3mm than the original ones. But seeing your temps i'd probably be happy with it also, depending on the gpu fan speed at 71 degrees. I usually adjust the fan curve so that the card reaches about 75 to reduce noise levels a bit.
My GPU score results for Time Spy running 1440p(basic free 3D Mark package):
- Default: 11 746
- 1965 @ 925 mem +850: 11767
- 1980 @ 950 mem +850: 11758
- 1995 @ 975 mem +1000: 12238
- 1995 @ 968 mem +1000 power limit 110%: 12432 (staying on this one for a bit, maybe lowering power limit to 105%)
@Bonusround
- Exhaust for all fans proved to be best for temps for me.
- Original feet
- I'm okay with the default fan curve. I usually listen to my GPU after a gaming session to see how ramped up it is. It's not very noticeable. Might tweak it a bit but honestly, the 10mm spacers have made a world of difference and keep things pretty cool.

Here's my temperature and Fan RPM for intake vs exhaust for my 3070FE
Haven't redone the experiment since I added new +5mm feet to the case.
Thanks, so exhaust seems to be the slightly better option as it seems!
so, A4-H20 is a thing - LIAN LI 2021 Digital Expo Unveils Chassis Prototypes (vortez.net)
so all the written media got to publish the day ahead and OT publishes 1 hour ahead of the actual reveal. GGWP Lian-li
Well that came out of the blue. Feels weird for there to not even be an announcement post on here, though I guess @dondan is kind of busy with this, the C4, and so on.
Yep, I was thinking the same. I only found about it and the Q58 on the ITX Anonymous Club thread on Bit-Tech this afternoon, totally off my radar...
This video is an prototype preview that was made for the Lian Li Expo 2021. The dimensions aren't final and we (Lian Li & DAN Cases) are currently tweaking these values for a nice compatibility with many cards.
This case will be sold and supported by Lian Li so the correct name will be something like LIAN LI A4-H20 (designed by DAN Cases).
Founder Edition cards:
The case will come with included stand offs that allowes to lift up the riser position. This will increase the distance between RTX 30x0 FE and PSU/MB-Tray for better airflow and temps on these cards.
Btw more pictures (not very polished):
I will create its own thread in the next days. At the moment i am very suprised because i didn't had any release dates for the LianLi Expo and the Optimum Preview.

Now dan a4 have a special version for water cooling. Please also provide a special version for air cooling if a4 continues to update.
Plz!
Plz!
This is great. I’ll probably end up with one.
If the specs aren’t final, then please make sure a NZXT 240mm AIO can fit. Also, some top mounted USB ports (in black) would be awesome.
OMG... this is THE A4 I was daydreaming of 
just the sleek design of the original one and that extra mm to acomodate 120mm fans (wich means more room for GPU and taller CPU coolers also). The closer approach of what I wanted is the Mjölnir, but the price and availability put her off my possibilities.
The removable bottom panel is a very good feature but I just think, seing the gains on the original A4, that it would be recommended to perforate it before final production. I noticed by the central screw that bottom panel has an structural function too, so one could expect less perforation density or a central zone without it to ensure the toughness of the spine's case, but it's understandable. That paired with slightly taller feet: nothing crazy, just 5-8mm to ensure a smooth intake provided by the top fans pushing air out of the case and that would be it IMHO.
On the other hand we could also go one step further with the original A4 approach and enhance the bottom exhaust/intake. Acording to the video it seems nearly impossible to put any fan below the motherboard but maybe the PSU area would be fittable. I'm thinking about our good friend NF-A9x14 since the central pilar don't seems to let enough space up to the front to accomodate a 120mm fan. Maybe the gain would be so marginal that is not worth all the trouble... I'm just thinking aloud. What do you think?

Frankly, I like the A4 as it is. Especially how thin it is with it's 115mm (although ideal for me would be an additional +3mm on the gpu side). Being able to use full sized gpu's, sfx psu's and 2 case fans within 7.25L is great. The 47mm clearance probably set by the sfx psu is just the right the sweet spot too for the L9a+fan duct or the BlackRidge and while we are only able to use 2 slot gpu's, that's only a limitation for people planing to use 3080 cards or above - which are not really for the majority anyway.
This H2O is mostly for thicker gpu's, so 3080 and up with 240mm aio's to cool 8 core cpu's. That is why I don't think that it is worth to use the H2O for a build featuring a cpu with 65w tdp and anything with a 3070 and below when you can comfortably run that in the much smaller A4 SFX (price aside).
However this might not be considered by most, as the H2O's price and especially it's wider availability could cripple the sales of A4's and even the upcoming C4's.
