The Whirly Fan is an item in Don't Starve Together. It requires 3 Twigs and 1 Petals to craft. It grants low protection from Overheating while it is spinning. It will spin only while the player is running, causing the Whirly Fan to spin and cool down the player.
The Whirly Fan has a durability of 1 minute and 30 seconds, and the durability will only go down while it is spinning.
However, it should be noted that the durability will decrease by 1% when being equipped after the first time. This may be a bug.
