Why each option

Data centers maintain specific temperature and humidity ranges to ensure optimal performance and longevity of IT equipment.

ABetween 62 °F - 81 °F and 40% and 65% relative humidity

While the temperature range is close, 65% relative humidity is generally considered too high and can lead to condensation and corrosion risks.

BBetween 64 °F - 81 °F and 40% and 60% relative humidityCorrect

According to industry standards such as ASHRAE TC 9.9, the recommended temperature range for data centers is between 64°F and 81°F (18°C - 27°C), and the relative humidity should be maintained between 40% and 60%. This range minimizes the risk of equipment failure due to overheating, electrostatic discharge, or corrosion.

CBetween 64 °F - 84 °F and 30% and 60% relative humidity

84°F (29°C) is at the higher end or slightly above the widely recommended maximum temperature, and 30% relative humidity is on the lower side, increasing static electricity risk.

DBetween 60 °F - 85 °F and 40% and 60% relative humidity

85°F (29.4°C) is generally considered too high for optimal and safe long-term data center operation.
