2006 Micro Blower: Ultra-Thin High-Performance Cooling
2006 Micro Blower: Ultra-Thin High-Performance Cooling
20×20×6mm. That's All the Space You Have. And It Still Works.
Designing for "thin" is a thermal management nightmare.
When you're working on smart wearables or high-integration modules with exactly 6mm of clearance, standard axial fans simply don't have the static pressure to push air through tight internal resistances.
If the air doesn't move, the heat stays—and your product fails.
The solution isn't just a "small fan." You need a high-performance blower engineered for high-resistance airflow paths.
Enter the 2006 series (MG2006) micro blower—the ultimate ultra-thin cooling solution.
What Makes the 2006 Different?
The 2006 micro blower is a centrifugal blower specially designed for ultra-thin applications where axial fans simply can't perform.
Unlike traditional fans, which primarily push air forward, the 2006 uses a centrifugal design to generate high static pressure, forcing air through restrictive spaces, heatsink fins, and tiny internal ducts.
The key difference: Static pressure vs. Airflow.
- Axic Fans: Excel at moving air through open spaces (high CFM, low pressure)
- 2006 Blower: Excell at overcoming resistance (lower CFM, high pressure)

Real-World Performance
At 3.7V: Stable 9,200 RPM – ideal for battery-powered wearables with efficiency demands
At 5V: 14,300 RPM – maximum airflow for high-heat devices in compact enclosures
The 2006 doesn't just "fit in" your device—it actually moves air where it needs to go, overcoming the airflow resistance that defeats standard axial fans.
Why Static Pressure is the Secret Sauce
Most engineers focus only on CFM (cubic feet per minute) when selecting cooling solutions—and while airflow is important, it's only half the story.
In ultra-compact devices (20×20×6mm spaces), static pressure is what matters most.
CFM vs. Static Pressure
💨 CFM (Airflow) - Measures how much air moves through open space - Best for: Open-vented applications with minimal resistance - Axial fans excel here
🎯 Static Pressure - Measures the force of air pressure – ability to overcome resistance - Best for: Restricted paths, heatsinks, ducts, tight enclosures - 2006 blower excels here
The 2006 advantage: Engineered to prioritize static pressure, delivering targeted airflow into high-resistance zones that standard fans can't reach.
Results: - Better heat dissipation in compact spaces - More effective cooling of hot spots behind components - Greater design flexibility in ultra-thin products

Frequently Asked Questions
What makes the DC2006 micro blower different from a standard fan?
The DC2006 is a centrifugal micro blower, distinct from axial fans in several key ways:
Design Differences:
| Aspect | DC2006 Micro Blower | Typical Axial Fan |
|---|---|---|
| Airflow Type | Centrifugal (radial) | Axial (straight-through) |
| Pressure | High static pressure | Low-moderate pressure |
| Airflow Path | 90-degree bend | Straight through |
| Noise | Higher (compression) | Lower (open flow) |
| Form Factor | 20×20×6.5mm | 20×20×6mm or larger |
| Applications | Confined spaces, ducts | Open ventilation |
Why Choose DC2006: - High Static Pressure: Essential for pushing air through filters, heatsinks, or confined enclosures where axial fans fail - Compact 90° Design: Allows airflow direction change in limited space - Positive Displacement: Delivers consistent airflow even with back pressure - Ideal For: Wearables with restricted vents, medical devices with filters, LED strips in tight channels
Comparison to Alternatives:
| Application | DC2006 (Blower) | DC4010 (40mm Fan) | DC3010 (30mm Fan) |
|---|---|---|---|
| Open ventilation | ❌ Overkill | ✅ Best | ⚠️ Good |
| Through filter/heatsink | ✅ Excellent | ❌ Weak | ❌ Weak |
| Wearable with vents | ✅ Good | ❌ Too large | ❌ Too large |
| Noise-sensitive | ⚠️ Louder | ✅ Quieter | ✅ Quieter |
Bottom Line: If you need to push air through restriction (filter, narrow duct, heatsink fins), DC2006 is superior. If you have open airflow, use DC4010 or DC3010 instead.
Can DC2006 run on 3.7V Li-ion batteries?
Yes. DC2006 operates on 3.3V-5.5V, making it compatible with single-cell Li-ion batteries.
Battery Compatibility:
| Battery Type | Voltage | Runtime (2,000mAh) | Notes |
|---|---|---|---|
| Li-ion 18650 | 3.7V | 8-12 hrs | ✅ Direct connection |
| LiPo 1S | 3.7V | 8-12 hrs | ✅ Direct connection |
| 2× AA alkaline | 3.0V | 10-15 hrs | ⚠️ Slightly below spec |
| 2× AA NiMH | 2.4V | 10-15 hrs | ❌ Under minimum voltage |
3.7V Operation Performance: - Speed: ~12,000-15,000 RPM - Airflow: 2.8-3.2 CFM - Current: 0.12-0.15A - Run time (2,000mAh Li-ion): 13-16 hours continuous
Voltage Linearity: - Performance scales predictably with voltage - 3.3V: ~80% of rated performance - 5.5V: ~120% of rated performance - Consistent: Allows fine-tuning via PWM or voltage adjustment
Battery Design Considerations: 1. Direct Connection Possible: No voltage regulator needed for 3.7V Li-ion—simplifies design 2. Low Voltage Cutoff: Li-ion drops to 2.8V at low charge—DC2006 may not run reliably below 3.0V 3. Recommendation: Add low-voltage cutoff (2.8-3.0V) to protect battery and maintain performance 4. Buck Converter: For stable 5V operation regardless of battery charge, use buck converter

For detailed fan/ blower selection, see Fan Selection Guide.
How do I reduce DC2006 noise level?
DC2006's 28-32 dB-A at full speed can be noticeable. Here are noise-reduction strategies:
Noise Sources in DC2006: 1. Airborne noise: Air turbulence at fan blades (dominant at high speed) 2. Bearing noise: Mechanical vibration (hydraulic vs ball bearing) 3. Structural transmission: Vibration transferred to device chassis 4. Motor hum: Electrical hum from motor windings
Noise Reduction Techniques:
1. Operate at Lower Speed - 3.3V operation: 20-23 dB-A (virtually silent) - 3.7V operation: 24-26 dB-A (very quiet) - 5.5V operation: 30-32 dB-A (maximum noise) - Recommendation: Operate at lowest speed meeting thermal needs
Optimal Speed Strategy: For most wearable/sensor applications: 3.7-4.0V optimal balance of airflow vs. noise
| Voltage | Noise | Airflow | Application |
|---|---|---|---|
| 3.3V | 20-23 dB-A | 2.5 CFM | Battery-powered wearables, bedside |
| 3.7V | 24-26 dB-A | 2.8 CFM | Typical wearable use |
| 4.0V | 26-28 dB-A | 3.0 CFM | Sensor cooling |
| 5.0V | 28-30 dB-A | 3.2 CFM | High thermal load |
| 5.5V | 30-32 dB-A | 3.5 CFM | Extreme cooling needs |
2. Improve Mounting (Reduce Structural Transmission)
Problem: Rigid mounting transmits vibration → chassis resonance → noise amplification
Solution: Use compliant mounting
Mounting Options:
| Mounting Method | Noise Reduction | Pros | Cons |
|---|---|---|---|
| Direct screw | Baseline | Secure | High transmission |
| Rubber grommets | 3-5 dB-A | Good isolation | Adds 1mm thickness |
| Vibration pad | 4-6 dB-A | Effective | Adds 2mm thickness |
| Double-sided foam | 2-3 dB-A | Low profile | Limited isolation |
| Silicone O-ring | 3-4 dB-A | Compact | Requires custom design |
| Magnetic floating | 6-8 dB-A | Excellent | Custom variant |
Recommended: Rubber grommets or vibration pad (4-6 dB-A reduction achievable)
3. Aerodynamic Optimization - Smooth intake/exhaust: Sudden air blockage = noise. Ensure gradual transitions - Avoid abrupt edges: Use aerodynamic air guides - Add diffusers: Reduce velocity gradients, lower turbulence noise
4. Acoustic Enclosures - Sound-absorbing foam: Line enclosure with open-cell foam around fan - Absorption: For <8mm path, 10mm foam sufficient. For larger, 20-25mm needed - Material: Polyester or melamine foam (density 20-30 kg/m³)
5. Bearing Selection - Hydraulic-bearing DC2006: Quietest → 3-4 dB-A quieter than ball bearing - Ball-bearing DC2006: Slightly noisier, but more durable - Recommendation: For noise-sensitive, specify hydraulic bearing
Real-World Noise Reduction Example:
Baseline: 30 dB-A @ 5V (direct screw mount, ball bearing)
After optimization: 1. Operate @ 3.7V → 25 dB-A (-5 dB-A) 2. Add rubber grommets → 21 dB-A (-4 dB-A) 3. Add acoustic foam → 18 dB-A (-3 dB-A) 4. Switch to hydraulic bearing → 16 dB-A (-2 dB-A)
Total: 14 dB-A reduction (30 → 16 dB-A). 16 dB-A virtually inaudible in ambient environment.
Noise Budgeting: - Target: <25 dB-A for wearables/medical (acceptably quiet) - Target: <30 dB-A for general electronics (not disruptive) - Target: <35 dB-A for industrial/machinery (acceptable)
Can DC2006 be used in 3D printers?
Yes. DC2006 can be used in 3D printers for specific applications.
3D Printer Cooling Overview:
| Component | Typical Fan | Reason |
|---|---|---|
| Hot-end cooling | 40mm (DC4010) | Compact, sufficient airflow |
| Part cooling | 40mm (DC4010) | Widely adopted, good performance |
| Electronics cooling | 40mm-120mm | Various sizes available |
| Enclosure ventilation | 80mm-120mm | Large volume, low speed |
DC2006 in 3D Printers:
1. Miniature 3D Printer (Compact) For ultra-compact handheld or desktop micro-printers:
- Hot-end cooling: DC2006 can replace DC4010 in ultra-compact designs
- Part cooling: Insufficient for most prints—DC4010/4020 recommended
- Electronics cooling: DC2006 adequate if thermal load modest (<10W)
- Enclosure: Not recommended—volume too small for enclosure
For mini 3D printer, DC2006 is acceptable if: - Hot-end temperature <260°C - Print volume <50×50×50mm - Print speed <30 mm/s - Primarily PLA
2. Heatsink Cooling for Ramps/All-in-One Boards Some 3D printer boards (Ramps 1.4 simplified, All-in-One Makerbase) use onboard MOSFET heatsinks:
- DC2006 application: Blow directly onto heatsink
- Advantage: 20×20mm fits board footprint, can mount with adhesive
- Benefit: Cools MOSFETs directly, reducing thermal throttling during long prints
- Note: Usually unnecessary for normal operation—but beneficial for heavy-duty printing (>24-hour sessions)
3. Filament Path Cooling For exotic filaments requiring minimal part cooling (ABS, Nylon, PETG):
- DC2006: Gentle 2.8 CFM airflow at 3.7V
- Compare to DC4010: Typically 6-10 CFM (overkill for ABS)
- Benefit: Slight cooling to reduce warping without freezing layers
Abs Cooling Strategy: - No active cooling → warp cracking - DC4010 → too much cooling → delamination, layer separation - DC2006 ✅ → gentle cooling → reduces warping, maintains interlayer adhesion
4. Print Chamber Temperature Management For enclosed printers with chamber heating:
- DC2006: Can circulate air within enclosure to maintain uniform temperature
- Mounting: 90° airflow direction useful—position to mix chamber air
- Application: Prevent hot/cold spots which cause layer shrinkage
Comparison to DC4010 (Standard 40mm part fan):
| Metric | DC2006 | DC4010 (Standard) |
|---|---|---|
| Airflow | 2.8-3.2 CFM | 5.2-6.5 CFM |
| Static pressure | Higher | Lower |
| Noise | 28-32 dB-A | 22-28 dB-A |
| Footprint | 20×20mm | 40×40mm |
| Part cooling | ❌ Insufficient | ✅ Excellent |
| Heatsink cooling | ✅ Good | ✅ Good |
| Power | 0.6-0.75W | 0.4-0.5W |
Conclusion: DC2006 is not recommended as primary part cooling fan for standard 3D printers. Use DC4010 instead. DC2006 is suitable for: - Ultra-compact mini printers - Heatsink supplemental cooling - Gentle ABS/Nylon/PETG cooling - Chamber air circulation
