Topic #: 3
A 5kW (power consumption) server keeps crashing with the message 'temperature too high'.
The intake temperature is measured at 25 C/77 F and a relative humidity (RH) level of 50%.
The exhaust temperature is 29 C/84 F and 45% RH.
The raised floor is providing an adequate amount of CFM/CMH at a reasonable velocity.
The pressure under the raised floor is approximately 25 Pa/0.1 inch HO.
Analyze the situation and indicate what the most likely cause is for this server to crash.
The server's repeated overheating despite adequate intake and exhaust temperatures suggests that dust buildup inside the server may be impeding heat transfer. Dust accumulation can obstruct airflow within the server, insulate components, and disrupt the convection-based cooling systems that regulate internal temperatures, leading to overheating and potential hardware failures.
Detailed Explanation:
While the intake and exhaust temperatures appear within acceptable ranges, internal dust can reduce airflow and impede cooling efficiency, causing internal components to overheat despite seemingly normal ambient conditions. Regular cleaning and maintenance are critical for preventing dust-related issues, especially in high-powered equipment like a 5kW server.
