When searching for information about case fans or coolers, people often mention the type of bearings these fans use. My question is, what exactly are fan bearings? What function do they serve? Are they meant to boost a fan's cooling ability? And importantly, do they influence overall performance?

A bearing is the component that keeps the fan inside the casing and enables it to spin. Many fan advertisements highlight bearings because this is often where failures occur, leading to a loss of performance.

If a bearing fails, the fan may become noisy and vibrate more. This can slow down its rotation, which in turn reduces cooling efficiency. Eventually, if the issue becomes severe, the fan might stop working altogether and need replacement.

They assist the axle the fan relies on. Refer to Wikipedia for more details.

A bearing is the component that keeps the fan inside the casing and lets it spin. Many fan ads highlight bearings because this is usually where failures occur, causing the fan to stop working.

If a bearing fails, the fan may become noisy, vibrate more, slow down, and lose cooling efficiency. Eventually, the fan might stop spinning entirely and need replacement.
