Gigabyte has announced that it is working with Incooling to improve the cooling features of the lockable R161 server platform. The first goal for technology development and prototyping is the server market, where higher speeds can bring huge benefits – for example, applications for the high-frequency trading market.
For this reason, Gigabyte and Incooling Server adapt to the R161 series, which previously relied on the Asetek Server LSL fluid circulation loop system to maintain overclocking and maximize performance. For various reasons, the new cooling technology seems to have changed a lot in terms of temperature and OC speed.
Up to “20 ° C lower core temperature”
“Incooling technology is able to bring data center temperatures far below traditional air temperatures, opening a new class of turbo servers,” the Gigabyte press release said.
Internal testing of sophisticated two-phase cooling technology on the R161 server is claimed to offer the following benefits; “The core temperature is lower by 20 ° C, which increases the clock rate by 10 percent and at the same time reduces the total power consumption by 200 watts.” The following diagram shows the basics of the phase change cooling technology used here.
The diagram shows an overview of special refrigerant flow that fills the system. This provides cooling when it changes from liquid to gas, after which the cooler is condensed back into liquid in the condenser, which is supported by one or more coolers / fans. Theoretically, the phase change system does not require a pump because the cooling / condensation cycle is driven by processor heat. However, you can see that the gigabyte circuit contains a pump, perhaps to ensure constant operation.
Gigabyte and Incooling will further enhance this cooling system to achieve better performance with lower power consumption – an important balancing act for the server. In the future, gigabyte server systems such as multi-node servers from the H series for high-performance computing and G series servers for artificial intelligence will be tested with this changing phase of cooling technology.
At Computex 2018, Case King / der8auer shows a phase switch without a pump that will “really be a product”, but has not yet been finished or shipped. At Computex 2016, Raijintek presents a “passive liquid cooler” with phase change fluid with a boiling point below 40 ° C – this product is also not available. Source
