Applications

• Raspberry Pi 4/5 Cooling: Ideal for "Ice Tower" style coolers or custom 3D printed cases that require directed airflow over the CPU.
• 3D Printer Part Cooling: Perfect for upgrading the part cooling fan on 5V printer mainboards or modifying print heads for better bridging performance.
• Electronics Enclosures: Force fresh air through dense component stacks where axial fans fail to generate enough static pressure.
• Portable Air Scrubbers: Small DIY solder fume extractors for close-up work.

Project Evolution:

From Passive to Active Pressure

• The Bottleneck: You've likely used standard 30mm or 40mm axial fans (like the standard Pi fan). While they move air, they struggle to push it through resistance, like a dense heatsink or a long duct.
• The Upgrade: This 5015 Blower is a Static Pressure Specialist. It unlocks the ability to use custom cooling ducts. You can now 3D print a focused nozzle to direct 100% of the airflow onto a specific component (like a stepper driver or nozzle tip) without backflow.
• Effort Level: Intermediate. Requires understanding of 5V power sources and basic mounting (M3/M4 screws).
• Safety Check: Since this is a 5V native device, it is Probots Logic-Safe™ ⚡, perfectly safe for direct connection to the 5V rail of a Raspberry Pi, Arduino, or ESP32 without needing a 12V boost converter.

Wiring & Safety Guide

• Pinout:
  • Red Wire: +5V DC
  • Black Wire: GND (Ground)
• Warning: DO NOT connect this to a 12V source (like a 3D printer PSU directly) or a 24V rail. It will burn out instantly. Always verify your voltage source with a multimeter before connecting.
• PWM Control: This is a 2-wire fan. Speed control can be achieved via voltage modulation (PWM on the power pin via a transistor/MOSFET driver). Still, it does not have a dedicated PWM signal wire or Tachometer output.

Frequently Asked Questions (FAQ)

• Can I run this 5015 fan directly from a Raspberry Pi GPIO pin? No, the GPIO pins cannot supply enough current. Connect the Red wire to the 5V pin (Physical Pin 2 or 4) and Black to GND (Pin 6).

• Is this fan compatible with 12V 3D printers, such as the Ender 3? Only if you step down the voltage. Most Ender 3s use 24V. You would need a buck converter to drop 24V to 5V to use this specific fan.

• Does this fan support PWM speed control? It is a 2-pin fan, so it does not have a dedicated PWM wire. You can control speed by pulsing the power using a transistor or MOSFET driver circuit.

• How loud is this fan compared to a standard 4010 fan? It is generally louder because it moves more air at higher pressure. At full 5V, you will hear the rush of air (whirring sound).

• What is the difference between a blower and an axial fan? An axial fan (standard square fan) moves volume but has low pressure. This blower (centrifugal) creates high pressure, making it better for pushing air through ducts.

• Can I use this with an Arduino Uno? Yes, you can power it directly from the 5V pin on the Arduino Uno, provided your power supply to the Arduino has enough overhead.

• What size screws do I need to mount this? The mounting holes typically fit standard M4 screws and nuts. Ideally, use a bolt with a washer to avoid cracking the plastic ears.

• Is the connector compatible with standard PC fan headers? No, this uses a JST-XH 2.54mm connector. PC motherboards usually use Molex KK or 4-pin PWM headers, though the pitch is similar, the locking mechanism differs.

• Can I reverse the polarity to reverse airflow? No, brushless DC fans will not spin in reverse if polarity is swapped. They may even be damaged. Always connect Red to Positive.

• Does this fan have ball bearings or sleeve bearings? This model utilises an oil-impregnated sleeve bearing for cost-effectiveness and quiet operation at lower speeds.

• What is the typical lifespan of this fan? Sleeve bearing fans typically last 30,000 to 40,000 hours at room temperature. Dust and high heat can reduce this.

• Can I use two of these in parallel on one 5V port? Yes, as long as your 5V source can supply ~0.5A (500mA) total. A standard USB port (500mA limit) might be pushed to the limit with two.

• Is this fan waterproof? No, it is not IP-rated. Do not expose it to water or conductive fluids.

• Why is my fan making a grinding noise? Check for debris inside the blower wheel. If it's clean and still grinding, the bearing may be dry or damaged.

• Can I use a potentiometer to control the speed directly? A standard potentiometer will burn out due to the current. You need a PWM controller or a transistor circuit controlled by a pot.

• What is the maximum air pressure? While we don't have the exact static pressure curve, 5015 blowers typically generate 10-15mmH2O, significantly higher than axial fans.

• Is this suitable for a Part Cooling Fan upgrade? Yes, the 5015 is the "gold standard" for upgraded 3D printer part cooling, provided your mainboard supports 5V output for fans.

• Does it come with a duct? No, this is the raw fan only. You must print or buy a duct suited for your specific application.

• How do I clean dust out of the blower? Use compressed air (canned air) to blow through the intake. Do not try to disassemble the casing as it is usually glued or snap-fit tight.

• Will this work with a 3.7V LiPo battery? It will spin, but at a reduced speed and lower airflow. It is optimised for 5V.
