The only issue you that should concern you is condensation. A drastic change in temperature due to air conditioner
from one extreme to another, for example if you were to maintain a room temperature of 69-73 degrees and then promptly relocate the laptop to much higher temperature such as inside of a car, or or equivalent with a 10-15 degree difference it's possible to create moisture. This also applies to desktops under the same conditions. Otherwise, keeping your unit cool will prolong life of hardware.
Heat is a computers worst nightmare.
