If it feels like you're taking an actual lead pencil to your eyes, your eyeliner is too cold. There are two solutions to this problem: one is washing your hands, taking the top of your eyeliner between two fingers and holding onto it for around 20 seconds, and the other is using a blow dryer to heat up the tip for two or three seconds.
uhmm...no, it doesn't work like that
fan has not enough pull power to suck the colder air from floor level, you need to force warm air that is stored on ceiling level down so it mixes with the colder
that is much more efficient way of heating up large air volumes
