StorageReview Direct-to-Chip Liquid Cooling Results | ZutaCore

Calling all GPUs and CPUs!! The first independent review of waterless two-phase, direct-to-chip liquid cooling is out, and according to StorageReview, “the results were dramatic."

With ZutaCore^® HyperCool^® cold plates now available for the world’s leading CPUs and GPUs from Intel, AMD, NVIDIA and others, the results of this testing are significant. Just last week, Reuters reported that Blackwell AI chips were encountering problems with servers that overheat, causing some customers to worry they will not have enough time to get new data centers up and running. ZutaCore’s HyperCool liquid cooling can not only solve this over-heating problem, but it does it cost-effectively and sustainability – with zero use of water required!

DRUM ROLL PLEASE ... HERE ARE THE RESULTS

While you can read the full review (or watch the YouTube Video) at this link, we’ll give you some of the key highlights below.

• Test System Used: A Supermicro chassis with dual AMD EPYC Bergamo CPUs, each boasting 128 cores. With 256 cores under the hood and 768GB of RAM, this server is designed to handle dense workloads, especially in AI and data-intensive environments.
• Baseline Results Before installing Liquid Cooling: In baseline tests, before installing liquid cooling technology, the test system struggled. The system quickly reached thermal limits, causing the CPUs to throttle performance to stay within safe operating temperatures. Sustained heavy loads resulted in CPU temperatures hovering near 85°C, with noticeable dips in clock speeds.
• Results After Installing HyperCool Direct-to-Chip liquid cooling: Once the system was retrofitted with ZutaCore liquid cooling, Storage Review reran the same baseline benchmarks and found that CPU temperatures, under full load, dropped significantly, with peak temperatures remaining under 65°C. More importantly, thermal throttling was eliminated. The two-phase system kept the Bergamo CPUs running at higher sustained clock speeds throughout the test. Power consumption dropped and quieter operation was immediately noticeable.

The Stand Out Advantage Was Energy Savings

According to Storage Review, one of the most significant advantages of the ZutaCore system is the potential for energy savings. Not only does the reduced reliance on air cooling translate into real-world energy cost savings, but the system also allows the server to operate in higher ambient temperatures without risk of overheating. “This feature is invaluable for data centers looking to optimize their PUE (Power Usage Effectiveness) by raising the temperature of their facilities,” said the Storage Review Lab.

The Proof is in the Pudding - Bring on the AI Factories

As this independent review demonstrates, two-phase, direct-to-chip liquid cooling is the ideal solution for emerging AI factories expected to output 50-100 megawatts of computing power. Not only can each HyperCool cold plate cool up to 2,800 watts, but it’s also the ONLY liquid cooling solution that can deliver a 100 percent water-free AI factory design. This is why all the leading CPU and GPUs are migrating to this liquid cooling approach, and it’s why HyperCool will transform the world through its sustainable AI performance.
