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 intermittentlyPower 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.
