FAQ

1. The fan is too loud—what can I do?
Check mounting: Loose screws cause vibration noise.

Remove dust: Build-up increases air resistance and noise.

Lower RPM: Use BIOS or software (e.g., SpeedFan) to reduce speed.

Bearing type: Sleeve bearings start quiet but wear out; double-ball lasts longer and is slightly louder; hydraulic is a good middle-ground.

2. Fan won't spin or starts/stops intermittently
Power check: Be sure the 3-pin/4-pin connector is fully seated.

Fan-stop mode: Many boards shut the fan off below ~40 °C; this is normal.

Bearing wear: Sleeve types may refuse to start when oil dries—replace the fan.

 
3. Which direction should the fan face?
Look for arrows: Printed on the frame (→ exhaust, ← intake).

General rule:
– Front/side: intake (cool air in).
– Rear/top: exhaust (hot air out).
– Tower coolers: push air toward the rear exhaust.

4. 3-pin vs. 4-pin difference?
3-pin: DC voltage control, fixed or stepped speeds.

4-pin: PWM, motherboard varies speed automatically (quieter, more precise).

Compatibility: 4-pin plugs into 3-pin header but runs full-speed or DC only.

5. How long will the fan last?
Sleeve bearing: ~2–3 years (less in dust/heat).

Hydraulic bearing: ~4–5 years (quieter, sealed better).

Double-ball bearing: 5–10 years (24/7 tolerant).

6. How can I make the fan quieter?
Use rubber pegs or grommets instead of metal screws to cut vibration.

Inline resistor cable or "low-noise adapter" to drop voltage (reduces airflow).

Smoother fan curve in BIOS: keep RPM low until temperature rises.

7. Connect to motherboard or power supply?
Motherboard header: enables speed control (best with 4-pin PWM).

PSU Molex: runs at 12 V full speed, simple but loud.

Splitter okay: but stay ≤ 1 A total per header (usually 3–4 fans).

8. The label says 12 V—why does it still spin at 5 V?
Wide tolerance: most motors run 5 V–13 V, but may not start below ~7 V.

9. More blades = better?
More blades: higher static pressure (good for radiators), slightly louder.

Fewer blades: higher airflow (good for case ventilation), lower noise.

Typical balance: 7–9 blades.

10. How do I know the fan is dying?
Listen: clicking or grinding = bearing failure.

Check RPM: software like HWMonitor; far below spec (e.g., 300 RPM vs. 1200 RPM) is a red flag.

Power off and flick: blade should spin freely; wobble or stiffness means worn bearings.
