In data centers, equipment such as servers and network devices operate continuously, and as a result,the amount of heat they generate becomes extremely high.
Therefore, efficient cooling is essential to maintain stable system operation.
Optimal fan selection requires taking into account airflow, static pressure, power consumption, and other parameters based on the equipment design and installation conditions.
This article provides an overview of the equipment in data centers that utilize fans, as well as the types of fans typically used in these applications.
Let’s take a look at which types of equipment in data centers are equipped with fans.
Network DevicesNetwork devices include switches responsible for data transmission, routers that manage routing paths, and firewalls that provide security protection.
To cool the internal components of these devices and ensure stable operation and long equipment life, fans are installed.

Server RackThe top of the rack is equipped with Centrifugal Fan that provides excellent airflow and static pressure, allowing for efficient heat dissipation.
Additionally, to prevent heat buildup and efficiently exhaust heat from servers, a φ200 × 70 mm fan is sometimes installed on the rear door of the server rack.

Servers and network equipment in data centers operate around the clock and must maintain a high level of reliability at all times.
Without proper management of the large amount of heat generated during operation, the risk of equipment malfunctions or shutdowns increases.
Furthermore, exposure to high temperatures can reduce the performance of critical components or lead to failures, potentially resulting in system-wide shutdowns or data loss.
Therefore, to ensure stable system operation, it is essential to implement high‑performance cooling and optimize the thermal design.
Data centers run numerous fans, and the efficiency of cooling directly affects power consumption.
Optimizing the thermal design of equipment and facilities, along with the use of low‑power fans, enables efficient cooling and contributes to reduced power consumption, lower operating costs, and minimized environmental impact.
Electronic components are sensitive to high temperatures, and insufficient cooling can lead to performance degradation, reduced service life, and a higher risk of failure.
Proper temperature management reduces the stress on components, contributing to longer equipment life and lower maintenance costs.
Selecting reliable fans is key to ensuring long‑term stable operation.
