Data centers can generate a significant amount of noise. Why? Because noise is a byproduct of traditional data center operations. Hundreds of servers (more in hyper-scale data centers) running simultaneously in a compact space can produce a lot of noise. It is estimated that the average noise level around servers can reach 92 A-weighted decibels (dBA). Not to mention the noise generated by the equipment typically needed to keep servers cool.
Research shows that HVAC systems running continuously can produce noise levels exceeding 80 dBA, nearing the maximum acceptable threshold of 85 dBA set by the National Institute for Occupational Safety and Health for 8-hour exposure. As the density and power of data centers increase, the global demand for greater computing power continues to grow, escalating the cooling needs of data centers. We need new cooling methods, and noise control should also be a consideration for data centers.
One increasingly popular alternative is immersion cooling, which involves submerging all computer components in an insulating liquid to maintain ideal operating temperatures. As a practical solution to the thermal issues of data centers, this technology is being adopted more widely.
Moreover, immersion cooling is quiet, potentially eliminating the hum generated by HVAC systems while providing a range of other benefits for your operations. In an era of labor shortages, creating a safe work environment where employees can thrive becomes a key advantage.
Noise: A Potential Hazard in Your Workplace
According to NIOSH, occupational hearing loss is one of the most common occupational diseases, which can be permanent. Furthermore, the organization estimates that about 22 million American workers are exposed to hazardous noise levels each year. The consequences of this are significant. Hearing loss is associated with difficulties in communication, as well as other health issues such as tinnitus, heart problems, cognitive decline, and mental health challenges. Therefore, excessive noise poses a real health and safety threat in your facility.
Additionally, noise can lead to inefficient data center operations, including:
- Communication problems among technicians, potentially resulting in poor operational outcomes.
- Increased stress that disrupts focus, leading to lower work quality or operational safety issues.
- Reduced productivity and increased absenteeism.
By eliminating the continuous noise associated with typical HVAC systems, data centers can alleviate these issues, creating a quieter, calmer, and healthier workplace.
Benefits of Immersion Cooling for Data Centers
In addition to reducing noise levels associated with traditional HVAC systems, immersion cooling offers other advantages:
- Increased Power Density: Immersion cooling allows data centers to accommodate and maintain server infrastructure for higher computing density to meet growing demands.
- Improved Thermal Performance: Systems using effective thermal management fluids can reduce throttling or downtime of equipment.
- Enhanced Power Usage Efficiency: Immersion cooling eliminates the need for energy-consuming air cooling systems, allowing equipment to transfer more power consumption directly to the hardware.
- Increased Sustainability: Single-phase immersion cooling uses less water than other cooling solutions/technologies and does not rely on carbon-fluorine based liquids (commonly used in two-phase cooling), which may exacerbate global warming and adversely affect chemical reactivity.
- Environmental Adaptability: Immersion cooling does not require the introduction of outside air to cool IT equipment, allowing data centers to be built in any geographical location.
Today's data center operators need to accomplish more work with less energy, smaller physical space, and shorter downtime, while considering the environmental impacts of data centers. Immersion cooling provides a long-term solution to address the thermal issues plaguing modern data centers.
