How to Tell If a Desk Fan Is Quiet Enough for Your Bedroom
Check the decibel rating and speed control granularity before you buy.
If you want to know how to tell if a desk fan is quiet enough for bedroom use, look for a decibel rating under 30dB and granular speed controls. The Coolhill USB Desk Fan hits these marks with a claimed 28dB noise level and 100 adjustable speed settings.

Why Granular Speed Control Matters for Sleep
Standard fans only give you three or four speed options, which often force you to choose between a weak breeze and a loud, roaring motor. The Coolhill fan uses a digital display and touch controls to let you scroll from 1 to 100. This lets you find the exact point where the airflow keeps you cool without triggering a high-pitched whine that keeps you awake.
Keep in mind that the 10-hour battery life only applies to the lowest speed settings; running the fan at maximum speed will drain the 3000mAh battery much faster.
