100% burn‑in tested
Every 24V 4010 fan runs 4~24 hours before shipment. Full electrical, noise, and vibration check.
Global logistics
Samples in 3‑7 days · Bulk order 15‑25 days · DHL / FedEx / sea freight.
1. Incoming Material Inspection
Bearings, PCBs, ICs, wires, and frames are inspected upon arrival. Non-conforming materials are rejected before production starts.
2. In-Process Quality Control
During assembly, operators check soldering quality, impeller balance, and insulation resistance at key checkpoints.
3. 100% Burn-In Test
Every single fan runs continuously for 4 to 24 hours under rated voltage. This stabilizes the bearing and reveals any early failures.
4. Performance Test
After burn-in, each fan is tested for:
Airflow (CFM) – wind tunnel or anemometer
Noise (dBA) – anechoic chamber
Current & power consumption
Speed (RPM) – tachometer
5. Dielectric Strength & Insulation Resistance
AC fans: 1500V AC / 1min. DC fans: 500V AC / 1min. No breakdown allowed.
6. Final Visual & Packaging Check
Label accuracy, connector condition, wire length, and packaging integrity are verified. Each unit receives a unique lot number for traceability.
Result: Less than 0.3% field failure rate. Every fan comes with a test report upon request.
FAQ of 24V 4010 Ball Bearing Fan
What does “4010” mean in a cooling fan?
40 = 40mm frame length and width. 10 = 10mm thickness. It’s the standard metric notation for miniature fans. Other common sizes include 4020 (40x40x20mm), 6025 (60x60x25mm), and 9225 (92x92x25mm). The 4010 is one of the thinnest options, ideal for tight spaces like 1U servers, compact power supplies, and portable electronics. Thinner fans move less air but fit where others won’t.
Can I get this fan with PWM and tachometer (FG) signal?
Yes. Our LKD4010B-24H includes both PWM speed control and FG tacho output. PWM lets you adjust fan speed based on temperature – quieter at low loads, full speed when needed. FG tells your system the exact RPM so you can verify the fan is working. Other models can add these features as custom options. Lead time for PWM/FG customization: about 10-15 days for samples.
Is the 24V 4010 fan suitable for outdoor cabinets?
Yes – with conformal coating and IP56 protection. Standard fans are for indoor, clean environments. Outdoor use exposes fans to moisture, dust, and temperature swings. Conformal coating protects the PCB from corrosion. IP56 keeps dust and water jets out. Ball bearings handle wide temperatures better than sleeve bearings. LINKWELL offers all these options. Lead time for outdoor-ready 4010 fans: 15-20 days for samples.
What is the typical lead time for custom 24V 4010 fans?
Samples: 7-10 days. Mass production: 20-25 days after sample approval. Custom connector or cable? Add 2-3 days. Conformal coating or IP56? Add 3-5 days. Private label? First order takes 15-20 days for samples. Standard off-the-shelf models ship in 3-5 days. We quote realistic lead times and rarely miss them. Need faster? Talk to us – expedited service is sometimes available.
How long will a 24V 4010 ball bearing fan last?
Rated for 50,000 hours L10 at 25°C. That means 90% of fans will still be running at 50,000 hours. In real-world conditions – dust, heat, vibration – expect 30,000-50,000 hours. That’s still 3-5 years of continuous 24/7 operation. Sleeve bearing fans typically last half as long. Proper mounting, clean air, and staying within voltage specs all help maximize life. We use NSK and NMB bearings.
