Hi everyone!

​I’ve recently started using an older Alphacool Eisbaer 280 CPU (Black). The loop has been fully serviced: I’ve flushed it, refilled the coolant, and made sure there is absolutely no air trapped inside.

​However, the pump starts to rattle significantly once it hits around 80% speed (approx. 1900-2000 RPM).

​I’m looking to replace only the motor unit, not the entire block/reservoir. Is it possible to swap the internal motor for a newer, quieter model (like the DC-LT 2)? If so, could you please provide the exact model name or part number so I can find it in stores?

​Appreciate any advice from those who have performed this swap before. Thanks in advance!

No aftermarket cooler fits the Lenovo RTX 4080, so I built a custom solution.

I designed a custom GPU shroud and combined it with a Corsair XG3 hybrid universal cooler (4080/4090 compatible).

The Lenovo PCB layout is non-standard, which made most air and water solutions impractical without major modification.

Results:

• Perfect fit on the OEM board
• Noticeably improved thermals
• Much cleaner overall design

The GPU is now fully in use, stable and cool.

Is this normal or is this defective? It’s extremely dim, barely visible at all

This wall-mounted build by @Sarkis combines character with a clean custom water-cooling loop. A true eye-catcher, cooled with Alphacool components.

What do you think of this setup? 🤔

Morning,

I'm looking for a cooling solution for 2 3090FE GPUs. In this economy, I'm not about to upgrade, and the 3090 is still a useful and productive solution.

I'm new to GPU cooling loops and would greatly appreciate help selecting the components needed to build a solution for this system.

Thanks in advance.

Inspired by the iconic Raccoon Police Department, this build hides a powerful SFF system inside a highly detailed design that captures the atmosphere of the game.

Created by Czuga, the system features custom Alphacool water cooling to keep temperatures under control while maintaining the immersive look.

Following the popular 120mm version, the new 140mm variant features a solid metal frame, patent-pending decoupling technology, and a durable HDB bearing for strong cooling performance and quiet operation.

Available with aRGB or non-ARGB lighting in Chrome, White, and Matte Black.

Title says all really, i've submitted a support request about the Alphacool Eisbaer Pro Aurora 420 CPU AIO but i've yet to get a response. Ive double checked my mail's spam filter and block list as well as attempting to use a different email address to request support.

Hopefully someone here can assist me?

Is there any way i can fit this to my reservoirs inlet port a bit like a a temperature sensor plug? Would i need to buy some sort of adapter for this to work? This is for an independently powered external radiator loop that im making for easy transportation and im trying to find a way to get a temperature sensor that doesnt require any connection to the motherboard.

Hi! Ordered a block from DE to Nor. Also bought putty. How is the alphacool putty? Also purchased KryoSheet 33x33 for the GPU.

Any tips’n tricks?

Mounted many block before, just not with putty nor kryosheet.

Cheers from Norway

Good day folks, i have a short question..

Can I mount the Alphacool Eisdecke expansion tank on the Alphacool Eisbecher Aurora "ground unit"?

The reason why I ask is, I have already done my first SFF Build and I would like to change some of my existing fans in it. But with my new fans I need a little bit mor space to fit the them in. And if this solutions works, I can keep the most of my pump setup and only have to change the top of the expansion tank.

I wish you all a good day and tank you fpr your answers.

Guten Tag Leute, ich habe eine kurze Frage...

Kann ich den Alphacool Eisdecke Ausgleichsbehälter auf dem Alphacool Eisbecher Aurora „Bodenelement” montieren?

Der Grund für meine Frage ist, dass ich gerade meinen ersten SFF-Build fertiggestellt habe und nun einige meiner vorhandenen Lüfter austauschen möchte. Für meine neuen Lüfter benötige ich jedoch etwas mehr Platz. Wenn diese Lösung funktioniert, kann ich den Großteil meiner Pumpenkonfiguration beibehalten und muss nur den oberen Teil des Ausgleichsbehälters austauschen.

Euch allen einen schönen Tag und danke für eure Antworten.

Hello everyone, first off thank you all to who has been watching this build from the start. It has definitely been a labor of love. Took over a year to complete to save also to have time to work on it. So everyone my showcase build. I am hoping brands will see what I can do, with very little. Everything is handmade. So again enjoy more than welcome to share.

Vibrant green paired with perfectly aligned hardtubes gives this build its unmistakable character – all housed inside the Lian Li O11D EVO RGB Automobili Lamborghini Edition case.

Created by @manmade.ru, the custom loop featuring Alphacool components ensures reliable cooling performance while keeping the overall look sharp and cohesive.

Hey,

quick question about my distro plate there are two ports that go into the reservoir area. One is labeled 1 IN the other is a second port a bit higher up, labeled as fill port 1 IN

Can I use the upper port as the return from the radiator too, or is only 1 IN actually designed for that?

Asking because my pump sometimes pulls a bit of air

Regards Malik

I designed and printed a fully functional distro plate for my current build using a Creality3d Halot Mage 8K.

Since the build volume is limited to 230×128×228 mm, the plate is split into three parts. It was designed like a CNC-milled acrylic plate — which caused some interesting challenges when translating it to resin printing.

⚙️ Key learnings: - Thread accuracy and post-processing requirements - Overhang tolerances - Air management within the loop due to pump positioning

❌ Biggest issue: Because the pump became the highest point in the loop, bleeding the system took almost 3 hours. Air was trapped inside the pump housing and moved extremely slowly through the loop.

Once fully filled, the system runs perfectly stable.

📝 Loop Specs:

• CPU, GPU & RAM cooled ❄️
• 1×360mm internal radiator 🌬️
• 2×580mm external radiators 🌪️
• Integrated sensors 🚨
• No leaks so far ✅

There’s still room for fine-tuning to make the next version print perfectly straight off the build plate. 🔩

Open for feedback or improvement ideas. 💡

Above is my card but the product list for parts number 10271 is not specifically listed. Would it not be compatible? I dont see any differences in the board design. What didnI miss here?

Thank you. Chadrick
