Description
QIDI X-Max / X-Plus Extruder Fan — 24V 4010 Ball Bearing Cooling Fan
The QIDI X-Max / X-Plus Extruder Fan is a 24V DC 40x40x10mm (4010) ball-bearing axial cooling fan rated at 7000 RPM and 12 CFM, designed as a direct OEM replacement for the hotend/extruder cooling fan on QIDI X-Max, X-Max II, X-Plus, and X-Plus 3 3D printers, priced at $39.99, with a pre-crimped 2-pin JST connector for plug-and-play installation in 5-10 minutes.
The extruder cooling fan is one of the most critical — and most often overlooked — components in a 3D printer. It keeps the hotend's heat break cool, preventing heat from creeping up into the cold end and causing filament jams (heat creep). When the extruder fan fails, your printer will start experiencing random filament jams, stringing, and eventually complete clogs. The QIDI X-Max / X-Plus Extruder Fan is the genuine OEM replacement, designed to match the original fan's airflow, noise level, and connector exactly.

Key Features
Double Ball Bearing for Long Life
The fan uses double ball bearings instead of sleeve bearings, providing a rated life of 50,000 hours at 25°C — roughly 3x longer than sleeve bearing fans. Ball bearings also maintain consistent RPM and airflow over the fan's lifetime, whereas sleeve bearings degrade and slow down as the lubricant dries out.
Optimized Airflow for Hotend Cooling
At 7000 RPM and 12 CFM, this fan delivers exactly the airflow needed to keep the X-Max/X-Plus hotend's heat break at the optimal temperature. Too little airflow causes heat creep and jams; too much airflow wastes power and creates unnecessary noise. QIDI has calibrated this fan to match the hotend's thermal design perfectly.
Pre-Crimped JST Connector
The fan comes with a 250mm cable terminated in a 2-pin JST-XH connector, identical to the original. No soldering, no crimping, no connector adaptation — simply unplug the old fan and plug in the new one. The cable length matches the original, so there is no excess cable to manage.
Quiet Operation at 28 dB
At 28 dB(A) measured at 1 meter, this fan is quieter than a whisper. The optimized blade design and precision ball bearings minimize turbulence and vibration noise. You will hear the printer's stepper motors and part cooling fan, but the extruder fan will be nearly inaudible.
OEM Quality and Fit
This is the exact same fan used in factory-new QIDI X-Max and X-Plus printers. Same dimensions, same connector, same airflow, same noise level, same cable length. Replacing a failed fan with this OEM part ensures your printer performs exactly as it did when new.
Pros & Cons
Pros
- Plug-and-play installation: Pre-crimped JST connector, 5-10 minute install, no soldering or tools beyond a screwdriver.
- Double ball bearing: 50,000-hour rated life — 3x longer than sleeve bearing fans, consistent RPM over time.
- OEM exact match: Same dimensions, connector, cable length, airflow, and noise as the original factory fan.
- Quiet at 28 dB: Optimized blade design and precision bearings produce minimal noise — quieter than a whisper.
- Prevents heat creep: 12 CFM at 7000 RPM keeps the heat break cool, preventing filament jams and clogs.
- 24V compatible: Matches the X-Max/X-Plus 24V electrical system — no voltage converter needed.
- Includes mounting screws: 4 M3 screws included, so you do not need to source hardware separately.
- Wide compatibility: Works with X-Max, X-Max II, X-Plus, and X-Plus 3 — four printer models covered.
- Lightweight at 18g: Minimal added weight to the extruder carriage, no impact on print quality or speed.
- Affordable at $39.99: Much cheaper than a service center repair or replacing the entire hotend assembly.
Cons
- $39.99 is expensive for a 4010 fan: Generic 4010 24V fans cost $5-12. The QIDI premium is for the pre-crimped connector, exact match, and ball bearing quality.
- Only 4010 size: If you want to upgrade to a larger or more powerful fan (5015 blower), this is not the product — it is a direct replacement only.
- 90-day warranty: For a fan rated at 50,000 hours, 90 days feels short. A 1-year warranty would be more appropriate.
- Not PWM-controlled: The fan runs at full speed (7000 RPM) whenever the printer is on. There is no speed control via firmware (some aftermarket fans support PWM).
- X-Max/X-Plus only: The connector and cable are specific to QIDI printers. It will not work with other brands without connector modification.
- No tachometer output: The 2-pin connector provides power only — no RPM feedback. The printer cannot detect if the fan has failed (a 3-pin or 4-pin fan would allow RPM monitoring).
- Plastic frame: The fan frame is plastic (PBT), which can deform at very high temperatures (above 70°C). In normal printer operation this is not an issue, but in a poorly ventilated enclosure it could be.
- Shipping time: Free standard shipping takes 15-25 business days. If your fan has failed completely, 3+ weeks of printer downtime is significant.
- Single fan only: The X-Max/X-Plus may have multiple fans (extruder, part cooling, controller). This product is only the extruder fan — you may need to purchase other fans separately.
- No anti-vibration mounts: The fan mounts directly to the plastic duct with screws. Rubber anti-vibration grommets would reduce vibration noise further but are not included.
Installation Overview
Replacing the QIDI X-Max / X-Plus Extruder Fan takes 5-10 minutes and requires only a Phillips #1 screwdriver. The process:
- Power off and unplug the printer. Wait 2 minutes for capacitors to discharge.
- Locate the extruder fan on the side of the hotend assembly (it blows air across the heat break fins).
- Remove the 2 mounting screws (M3) holding the fan to the fan duct.
- Gently pull the fan away from the duct and trace the cable to the motherboard connector.
- Unplug the 2-pin JST connector from the motherboard (note the pin orientation — red = +24V, black = GND).
- Plug the new fan's connector into the motherboard (red to +, black to -).
- Route the cable along the original cable path, securing with cable ties if needed.
- Mount the new fan to the duct with the 2 included M3 screws. Ensure the airflow direction is correct (label side faces out, air blows toward the heat break).
- Power on and verify the fan spins up immediately (you should feel airflow and hear it if you listen closely).
Warning: Always verify the fan's airflow direction before mounting. The fan should blow air TOWARD the heat break fins (not away from them). The side with the label is usually the exhaust side — air is drawn in through the label side and blown out the back. If installed backwards, the hotend will overheat and cause jams.
Frequently Asked Questions
What is the QIDI X-Max / X-Plus Extruder Fan?
The QIDI X-Max / X-Plus Extruder Fan is a 24V DC 40x40x10mm (4010) double ball bearing axial cooling fan with a pre-crimped 2-pin JST-XH connector, designed as an OEM replacement for the hotend cooling fan on QIDI X-Max, X-Max II, X-Plus, and X-Plus 3 3D printers. It runs at 7000 RPM, produces 12 CFM of airflow, and operates at 28 dB(A). The fan keeps the hotend's heat break cool to prevent heat creep and filament jams. Priced at $39.99, it installs in 5-10 minutes with no soldering required.
How do I know if my extruder fan needs replacing?
Replace the extruder fan if you notice any of these: (1) Random filament jams or clogs during prints, especially with high-temperature materials (ABS, PETG, nylon) — this is the #1 sign of heat creep from a failing fan. (2) The fan makes unusual noises (grinding, rattling, buzzing) — indicates bearing failure. (3) The fan spins slower than normal or stops spinning intermittently. (4) You can feel that the hotend's cold end (above the heat break) is warmer than it should be during printing. (5) The fan does not spin at all when the printer is powered on. (6) Increased stringing or oozing that was not present before. To test, power on the printer and hold a piece of paper near the fan — you should feel airflow. If not, the fan has failed.
Is the QIDI X-Max / X-Plus Extruder Fan compatible with X-Max II and X-Plus 3?
Yes. The QIDI X-Max / X-Plus Extruder Fan is fully compatible with all four models: X-Max (original), X-Max II, X-Plus (original), and X-Plus 3. All four printers use the same 4010 24V extruder fan with the same 2-pin JST connector and cable length. QIDI did not change the extruder fan design between these model generations. Before ordering, verify your printer is one of these four models by checking the name on the back panel or in Settings → About. The fan is NOT compatible with QIDI i-Fast, Q1 Pro, Q2, X-Smart 3, or other models (they use different fan sizes or connectors).
How difficult is it to replace the extruder fan?
Very easy — 5-10 minutes with only a Phillips #1 screwdriver. The fan is held by 2 M3 screws and connects via a simple 2-pin JST connector. Steps: power off, remove 2 fan screws, unplug the old fan from the motherboard, plug in the new fan, route the cable, screw in the new fan (verify airflow direction), power on and test. No soldering, no crimping, no firmware changes. Beginners can do it. The trickiest part is routing the cable through the extruder cable chain — take your time and follow the original cable path. Always verify the airflow direction before fully tightening the screws.
Can I use a generic 4010 fan instead of the QIDI one?
Technically yes, but there are important caveats. A generic 4010 24V fan costs $5-12 but: (1) it will not have the pre-crimped JST connector — you must solder or crimp the original connector onto the new fan's wires, (2) generic fans often use sleeve bearings (15,000-hour life) instead of ball bearings (50,000-hour life), (3) airflow and noise may differ (generic fans range from 5,000-10,000 RPM), (4) cable length may not match, requiring cable extension or shortening. If you are comfortable with soldering and want to save money, a quality generic ball bearing 4010 24V fan (like Noctua NF-A4x10 24V or Sunon MF40102VX) can work. For most users, the $39.99 QIDI OEM fan is worth the convenience and guaranteed compatibility.
What is the warranty and return policy?
The QIDI X-Max / X-Plus Extruder Fan comes with a 90-day manufacturer warranty covering defects in materials and workmanship (bearing failure, motor failure, connector defects). The return policy allows 30-day free returns for new, uninstalled items in original packaging (full refund). If the fan fails within 90 days under normal use, QIDI will replace it free of charge. Free standard shipping to the US takes 15-25 business days; express shipping (3-7 days) is available for an additional $15-25. The fan ships to 18 countries including US, CA, GB, DE, FR, IT, ES, NL, BE, AT, SE, DK, FI, IE, PT, PL, CZ, AU.
What should I do if the new fan does not spin?
If the replacement fan does not spin after installation: (1) Verify the 2-pin JST connector is fully seated in the motherboard socket — push until it clicks. (2) Check the pin orientation — red wire should connect to +24V, black to GND. Reversed polarity will not damage a DC fan but it will not spin (some fans are polarity-protected). (3) Test the fan by connecting it directly to a 24V power supply (if available) to confirm the fan itself works. (4) Check the motherboard's fan output with a multimeter — should read 24V when the printer is on. If 0V, the motherboard's fan MOSFET may have failed. (5) Ensure the fan is not physically blocked by the fan duct or cable. (6) If the fan works on direct power but not on the motherboard, the issue is the motherboard, not the fan. Contact QIDI support for further troubleshooting.
How long does the extruder fan last?
The QIDI X-Max / X-Plus Extruder Fan uses double ball bearings with a rated life of 50,000 hours at 25°C. In typical 3D printer use (4-8 hours per day), this translates to 5-10 years of operation. However, real-world lifespan depends on operating temperature — the fan is mounted near the hotend and operates in a warm environment (40-60°C), which can reduce bearing life to 30,000-40,000 hours (3-8 years). Sleeve bearing fans (found in some generic alternatives) typically last only 15,000-20,000 hours (1-4 years). Signs the fan is reaching end of life: increased noise, slower spin, intermittent stopping. Replacing the fan proactively every 2-3 years is a good maintenance practice to prevent unexpected jams.
Can I upgrade to a more powerful or quieter fan?
Yes, but with limitations. The X-Max/X-Plus extruder fan duct is designed for a 4010 (40x40x10mm) fan, so you cannot fit a larger fan without modifying the duct. Options within the 4010 form factor: (1) Noctua NF-A4x10 24V FLX — premium quiet fan (~18 dB, but lower airflow at ~8 CFM, may cause heat creep with high-temp materials). (2) Sunon MF40102VX-1000U-A99 — high airflow ball bearing fan (~15 CFM, 35 dB). (3) Delta AFB0424VHD — high-speed fan (~9000 RPM, 16 CFM, 40 dB). Any replacement fan must be 24V (not 12V) and have the same or greater airflow (12+ CFM) to prevent heat creep. You will need to solder/crimp the JST connector. For most users, the OEM QIDI fan provides the best balance of airflow, noise, and longevity.
Is the QIDI X-Max / X-Plus Extruder Fan worth $39.99?
Yes, for QIDI X-Max/X-Plus owners who need a replacement extruder fan. The $39.99 buys a genuine OEM 4010 24V double ball bearing fan with pre-crimped JST connector, 7000 RPM, 12 CFM, 28 dB noise, and 5-10 minute plug-and-play installation. A generic 4010 fan costs $5-12 but requires soldering/crimping, may use shorter-life sleeve bearings, and may have different airflow/noise characteristics. The QIDI fan's ball bearings (50,000-hour life) and exact OEM match justify the premium for most users. A failed extruder fan causes heat creep, filament jams, and ruined prints — a $39.99 replacement is cheap insurance compared to wasted filament and print time. The 90-day warranty is a downside, but the build quality is solid. Highly recommended for X-Max/X-Plus owners.
