What is a common symptom of insufficient cooling in a server?

A common symptom of insufficient cooling in a server is unexplained system crashes. When a server does not have adequate cooling, the internal temperatures rise dramatically, leading to thermal throttling or even outright shutdowns to prevent damage to the hardware. These safety measures can manifest as unexpected crashes, especially during periods of high workload when the system generates more heat.

While high CPU utilization can cause heat buildup and is related to cooling issues, it is not a direct symptom of insufficient cooling itself. High CPU utilization might result from software processes rather than being a clear indicator of cooling problems. On the other hand, frequent software updates and slow network response times are not typically related to thermal issues and would arise from different underlying factors. Understanding the signs of insufficient cooling is crucial for maintaining server reliability and performance.
