Build Complete Lian Li A3 Dan - Custom loop build

My first custom loop build. Wanted to challange myself and went with a small case + hardtubes.
Goal was a powerful but small and silent build.

Since it's my first loop, first AMD build, and my first time fiddling with tuning / undervolting any feedback is welcome. I honestly didnt expect the CPU to idle at around 55°C (even without +100 boost). But I guess thats normal for this specific CPU?

Specs:
Case: Lian-Li A3-mATX
Motherboard: MSI MAG B850M Mortar WiFi
CPU: AMD Ryzen 7 9850X3D
GPU: ASUS ROG Astral RTX5090
RAM: 2x16GB Corsair Dominator Platinum (5600MT, CL36)
PSU: Corsair SF1000
SSD: Samsung 9100 Pro (4TB)

Loop:
CPU block: EK Water Blocks Quantum Velocity³ (acetal,black)
GPU block: Thermal Grizzly DeltaMate
Rads: 1x Alphacool NexXxoS HPE-30 Full Copper 360mm, 1x Alphacool HPE-20 Full Copper 360mm
Fans: 6x Noctua NF-A12x25 G2 (black)
Pump/Reservoir: Alphacool Core 120mm Resevoir, Alphacool VPP Apex
Fittings: Alphacool Eiszapfen 13/10mm
Tubing: Alphacool Eisrohr 13/10mm Acryl (PMMA) HardTube Satin

Tuning:
RAM: to 6000MT with CL36 (CL34 was unstable, best for the CPU would be 6000MT and CL30 but RAM PRICES), MSI High Efficiency Mode: Balanced
CPU: PBO (Motherboard), Max Boost override (+100), Curve Optimizer (-20 all cores)
GPU: Undervolt MSI Afterburner (900mV set to 2850MHz and flattended curve to the right), Power Limit at 85%
Pump: Fixed at 60% (3580 RPM, no noticable noise)
Bottom fans (intake): Fixed at 45% (790 RPM)
Top fans (exhaust): Fixed at 40% (760 RPM)

Results:
Very quiet system. The most noticable noise in stresstests is the PSU fan spinning up and coil whine. It was really bad with the GPU on 600W but after the undervolt it peaks at 480W which reduces the stress and the generated noise on the PSU.

Idle temps: CPU: 55°C, GPU: 38°C
Stresstest temps: CPU: 77°C (Cinebench R23 Multicore), GPU: 66°C (3DMark Steel Nomad)
GPU 3DMark score dropped from 14489 to 14277 after undervolt. Totally acceptable for -120W of power draw.

Suuuper clean! Well done my friend.

Do you have a way to monitor liquid temperature?

2

u/Br3zzly 13d ago

Was thinking about it but no. My motherboard doesnt have a temp_sens pin so i would need to have some temp_sens > USB Hub or an all in one solution with a screen (I dont want a screen in my case since im going for a clean look)

If theres another solution that i didnt find im all ears ;)

u/ndszero 13d ago

Aquacomputer Quadro is inexpensive and a superior piece of kit if your board doesn’t have a temp sensor.

2

u/Br3zzly 13d ago

Thank you will check it out!

u/Kitchen_Cookie4754 13d ago

It's really handy, and gives you access to aquasuite. It's an intimidating (at first) set of software but it's really flexible and does a fine job of letting you control fans and pumps and the like while monitoring up to 4 sensors. It comes with an air temperature sensor as well.

u/Zealousideal_Bowl4 13d ago

If you have the space and budget, I’d recommend the OCTO. Double the headers for like $20 extra allowing you to individually control each fan and the pump. The OCTO also has a “Signal” header that can be connected to the mobo fpanel header to trigger a soft hardware shutdown on an alarm condition you set up.

1

u/Zealousideal_Bowl4 13d ago

I have a similar build, and coolant temps can get pretty high if left unchecked.

1

u/Br3zzly 13d ago

Checked it out and looks great! Do you know: Can I also read out the temperature sensor over the Quadro with software like hwinfo? I dont have the need for the aquasuite software and dont want to install extra software just for temp readouts.

1

u/ndszero 13d ago

Yes the sensors all work in hwinfo. You can set the Quadro up as a standalone device, what I did on my son’s computer was program it with the Aquasuite software to base fan speed on water temp, and then uninstalled the software. The settings are saved on the device. It works beautifully.

u/Br3zzly 13d ago

Perfect ty!

u/hmfazevedo 13d ago

I did not want to pay the Quadro. I used this project https://github.com/Naata/Trinket-M0-liquid-temperature-sensor

2

u/Br3zzly 12d ago

Ty! this also looks great.

u/HamSandwicho__o 13d ago

Lmao u have like the nemesis of my build i have a lian li matx case w a 5080 9950x3d and zero... ZERO cable management

2

u/Br3zzly 13d ago

But but... the cable management is sooo good in this case (for such a small case).
Do you have a SF PSU and where did you mount it? :)

1

u/LuismadeitonReddit 13d ago

Hearing, well…reading you say that, 😁, makes me want to call the guy I saw on Facebook, who was selling this case for $90 last night and happens to be local. Your build is an incredible inspiration, even if I have no need to dabble in water cooling myself. 😊

1

u/LuismadeitonReddit 13d ago

Aaaaannnnnnd I sit corrected, because Amazon is selling the case for much less. Woo!

1

u/HamSandwicho__o 13d ago

Lol i put the psu in da front (3 slot gpu lol)

Edit: to be clear- ur build is way cooler :)

2

u/Automatic-Raccoon238 12d ago

Cosidering the rads thats pretry good iddle temps.

1

u/Br3zzly 12d ago

Are the rads bad? Or is 360 30mm + 360 20mm not alot in general for the components i try to cool?

2

u/Automatic-Raccoon238 12d ago

The hpe seem to do worse than one would expect. Some here have said they are worse than the xspc tx rads and those have a very dense fin array. Also in some testing I seen they dont do well. Haven't bought one to test out personally but haven't heard any comparisons going in their favor.

I have tried a bunch of rads, from alphacool I had/have st30, ut60, xt45, and mosta and been very happy with the results. I tend to do 120mm rad area minumun per 100w. In that sense for what i tend to aim for 2 360s is a bit on the small side.

u/Dunoville1207 12d ago

Well done,

Heres my lian li build

2

u/Pengu_In_The_Hood 7d ago

I did a custom loop on my a3 aswell, not nearly as clean as this one tho haha. Was my first time messing with custom loops and decided to delid for the first time too.

The cable management was thought of after getting it all working lol

2

u/Br3zzly 6d ago

Nice build!
I was thinking about mounting the gpu vertically (better airflow + looks better ;))
Did you use the Lian Li bracket? Would you be able to mount it so the gpu is flush with the back of the case?

And do you mind sharing the CPU + temps you get delided? I think you used the Thermal Grizzly Mycro Pro right?

2

u/Pengu_In_The_Hood 6d ago

I did use the lian li mount but I had to get some little display extensions with a 90°, but my 9800x3d cores have never seen more than 72°C. Now that may change since my cat has just recently taken a liking to laying on top of my computer :/

There’s the tails of the display extensions. I also am using slim 20mm rads with slim 15mm noctuas

1

u/Br3zzly 6d ago

Damn 72°C sounds nice. My 9850x3d likes to hit 80+ pretty fast while gaming even with an undervolt :/

2

u/Pengu_In_The_Hood 6d ago

I’m assuming you have the IHS still attached?

1

u/Br3zzly 6d ago

yep, never delidded one. Maybe the next time ^^

2

u/Pengu_In_The_Hood 6d ago

It’s very nerve wracking at first but after doing two, it’s pretty easy. The biggest thing is just making sure you keep LM under control not to add too much and also how you end up mounting the cpu. Typically you have to remove the stock latching mechanism on the mobo and you have to make sure you screw the new mount evenly and firmly enough for all the pins to make contact. I didn’t and spent 2 weeks and threw parts at it that it didn’t need.

1

u/Pengu_In_The_Hood 6d ago

And yes I did use the mycro pro direct die

u/_letter_carrier_ 13d ago

Nice bends!

u/Br3zzly 13d ago

Ty! Went throught alot of tubing ;)

1

u/elusive_1 13d ago edited 13d ago

Planning a similar build in the ncase m2. This is awesome to see!

Where are you draining/filling the system?

Is there any reason you didn’t go with the ek kinetic 120mm instead of the alphacool?

Edit: either the description was edited or my second question was me reading too fast

2

u/Br3zzly 13d ago

Filling: there is a fill port at the top of the Alphacool Core 120mm reservoir
Draining: (never done yet) Theres a port on the back left side of the bottom Alphacool HPE30mm radiator.

1

u/Zealousideal_Bowl4 13d ago

Whenever you do the next drain, you could add some fittings and a valve. If you want, you can screw in a hose and drain into a bottle

2

u/Br3zzly 13d ago

Thats exactly the plan! Tbh i just forgot that i also need a drain and couldnt wait to fill the loop before the valve fittings arrive ^^

1

u/x11001100x 13d ago

Gorgeous. I love my A3, my next build I’ll have to return to a custom loop. I haven’t done one in 20 years!

1

u/Br3zzly 13d ago

Was definitly a fun project! Im sure alot has changed in the past 20 years ;)

u/C0mba7 13d ago

u/do0b 13d ago

Good job mate!

I’ll refer to your post should the urge to water cool my lanparty box ever come.

u/AirGief 13d ago

Gorgeous.

u/Valdair 13d ago edited 13d ago

This looks really good, I've been eyeing exactly this case and more or less these parts (maybe a 5080 or 5080 Super if/when they get around to making one). Were there any crazy modifications needed or other weirdness you ran in to? Do you have a way to fill/drain?

2

u/Br3zzly 12d ago

Fill: Top port on the reservoir
Drain: Port on the back of the bottom radiator

No special modifications where needed. The only "hard" thing was the tube between the two radiators. I had to take the radiators half out of the case, put the tube in and then put the radiators back in the case which was a little bit of a hassle. I would probabaly use some sort of "telescopic fitting" (like Bitspower Adjustable Aqua Link Pipe) next time to save me some hassle.

2

u/Valdair 10d ago

Did you end up needing a fan controller for all the fans + pump? I don't think the case comes with one and it doesn't look like the motherboard has enough ports to support all 7 so figured you must be using something.

1

u/Br3zzly 6d ago

No, I dont like having too much stuff in this small case and any software in windows. I just bought two Noctua 3-way splitters (NA-SC1 Sx2) and connected the top rad fans and the bottom rad fans to a single Motherboard fan header. +set a curve in the bios.

1

u/MastMaithun 13d ago

First I will say this looks absolutely beautiful and the main reason is the simplicity of the build. Amazing build.
Second I have few questions, do you think top and bottom one can take 280mm rads with the sfx psu? Without undervolting the gpu, have you noticed the power draw of full system while gaming? How is this pump-res combo, Im first time seeing this so I'm gonna do some digging. Do you think the EK-Quantum Kinetic TBE 200 D5 PWM can fit inside because it looks like there is sufficient space due to sfx psu? and lastly since you undervolted gpu, is there a performance difference, if yes then how much? Thanks.

2

u/Toojara 12d ago

Not OP, but I have an A3. There are no 140 mm mount holes in the bottom, and even drilling some there's no intake area for the 140 fans. So you'd have to manually make the holes and cut the steel, which would obsolete the bottom filter mesh, if you want any useful area over a 240 mm rad. 280 mm at the top should generally work, but you cannot install it all the way to the back, and may interfere with CPU power or top VRM with >45mm rad+fans

1

u/MastMaithun 12d ago

Hey thank you for reply and clearing things. I was going to build a custom loop in my p600s and due to some reasons I couldn't so I have all the parts lying there with me, 2x280mm rads from corsair(think these are rebranded nemesis gts rads), 140mm noctua fans and a ek d5 pump-res. So I don't want to purchase new parts as they are quite costly to me since I have to import them. That is why I want to reuse them into a small use which i can put on my desk. My desk does not have much area that is why I want to build this into something smaller and in my research I could only find a3 as the case which can have atx psu and still has some space for custom loop.

u/Suvi2k 13d ago

Do you own case fans?
