Will the car battery drain if the car fan is left on overnight?

A fully charged new battery, under spring/autumn ambient temperatures, typically allows the vehicle to start after being turned off with headlights and parking lights on for 1 hour (total power consumption 80-130W for 2 headlights and 2 parking lights). A standalone 25W small fan running for approximately 5 hours won't affect engine starting. Details about car fans are as follows: 1. Description 1: In-car entertainment systems are usually located around the center console, where traditional CD players (now mostly DVD players) are installed. 2. Description 2: DVD players contain power amplifiers that generate significant heat. The fan serves to dissipate this heat, functioning similarly to conventional household fans. Online images of car DVD players often clearly show these cooling fans.
