🎯 Why It Matters
Lifetime determines maintenance schedules and total cost of ownership. A fan with 70,000-hr L10 at 40°C will last ~8 years in continuous operation. But at 60°C, the same fan may only last 4 years. Always check the rated temperature when comparing lifetime specs.
📐 How to Read
L10 is always quoted at a specific temperature (typically 40°C or 25°C). At 40°C: consumer grade = 30,000-50,000 hrs. Industrial grade = 50,000-70,000 hrs. Premium = 100,000+ hrs. Each 10°C above rating roughly halves life.
📏 Typical Values
Consumer electronics: 30,000 hrs L10. Server fan: 70,000-100,000 hrs L10 at 40°C. Telecom: 100,000-200,000 hrs L10. Industrial: 50,000-80,000 hrs L10.

❓ Frequently Asked Questions
L10 vs MTBF — which matters more?
L10 is the standard for fans because failures are typically wear-out (not random). MTBF assumes random failures and is more applicable to electronics. For fan selection, prioritize L10 at your expected operating temperature.
How do I calculate actual lifetime for my application?
Start with the rated L10 at rated temperature. For each 10°C above rating, halve the life. For each 10°C below rating, double the life. Example: 70,000 hrs at 40°C becomes ~140,000 hrs at 30°C.
What else affects fan lifetime?
Dust ingress (use IP5x fans), vibration (check mounting), voltage spikes (use protected fans), frequent start/stop cycles, and chemical exposure. A fan in a clean, stable environment lasts significantly longer.
