Creating A Full Water Loop Using Only The Alphacool Eisbaer Solo

Author: Published on: Published in: Build Checks

With the latest processors becoming more powerful, and consequentially hotter, there’s more reason to get better cooling solutions to get the most performance out of these components. This is exactly the issue that one user faced with his Founders Edition Nvidia RTX 3080 Ti card and Intel 11700k CPU. In fact, the heat management in his system was so bad that while gaming, his GPU VRAMs recorded a temperature of 106°C and inevitably shut down. Having watched DIY Perk’s video on his “Breathing PC”, he approached us to figure out how a similar system can be implemented for his PC (the AIO cooling, not the breathing part).

Even so many fans can’t cool the system adequately in our tropical Singapore climate.

When he brought his PC for us to take a look, we realised instantly that this wasn’t going to be any ordinary build. For starters, his entire motherboard is mounted upside-down due to the design of his Be Quiet! case. We’ve not worked on inverted cases before, much less water cooling one so it was a challenge we instantly took up. Another unique part of this project was exploring the use of just a singular Alphacool Eisbaer Solo to run the entire water loop for both CPU and GPU. Since the Eisbaer Solo is a pump/res/cooler AIO, it definitely seems feasible but we were concerned with the flow rate considering the specified 75L/h is relatively low. To compensate for that, we used the thicker Alphacool NexXxos XT45 radiators with the new Alphacool Rise Aurora fans to ensure better cooling efficiency.

After a day of brainstorming, cleaning, and installing the components, we were finally satisfied with the final result:

Now, the interesting part comes as we do benchmarks to determine whether our plan worked. To say that we were surprised at the result would be an understatement. CPU clocked in an average of 62°C and a max of 65°C for multi-core on Cinebench. GPU clocked in an average of 57°C and hit a max of 58°C on Furmark. Even VRAMs stabilized at 72°C and briefly hit a high of 74°C. These results are right on par with the other custom water cooled systems that we’ve built, and those are with dedicated reservoirs and pumps! With these results, it poses a promising alternative for users looking to get water cooling for their systems at a very affordable and easy to install package.
