What is Too Hot for a Server?

Servers start to struggle if the temperature goes above 27°C. If it gets hotter than this, you risk overheating, which can cause the servers to slow down, malfunction, or even get permanently damaged. If you see temperatures creeping up to 30°C or more, it is a red flag to take action and cool things down quickly to protect your equipment. UPS lead acid batteries also start to degrade faster when presented with high ambient temperatures.
