The Blackmagic Design Spares - Pocket Cinema Camera 6K (PCC6K) - Fan Replacement Kit is the primary cooling component for the original 6K model. Because the 6K records high-bandwidth data (up to $6.1\text{K}$ BRAW), the internal processing chips generate significant heat that must be actively dissipated to prevent thermal shutdown or "fixed pattern noise" caused by a hot sensor.
Kit Components
The standard OEM replacement kit typically includes:
-
The Internal Brushless Fan: A specialized, low-profile blower fan designed for silent operation.
-
Vibration Dampers: Small rubber grommets that isolate the fan's kinetic energy from the camera body (preventing "hum" from being picked up by internal microphones).
-
Thermal Shroud/Ducting: (In some kits) The plastic or metal guide that directs airflow across the heat sinks.
When to Replace the Fan
The PCC6K fan is the only moving part in the camera, making it a common wear-item:
-
The "Grinding" Sound: If the camera makes a high-pitched whine or a mechanical grinding noise, the fan bearings have likely failed due to dust or debris.
-
Thermal Shutdown: If the camera displays a "High Temperature" warning and shuts off within 5–10 minutes of use, the fan is likely seized.
-
Internal Audio Interference: If you notice a low-frequency vibration or "buzz" on your internal audio tracks that wasn't there before, the fan's balance may be off.
-
Dust Accumulation: In heavy production environments, the intake vents (top and bottom) can suck in hair or fibers that wrap around the fan's axle.
Key Technical Specifications
-
Low Noise Floor: Specifically tuned to run at a variable RPM that minimizes acoustic noise while maintaining a safe operating temperature for the Main PCB.
-
PWM Control: The fan is controlled via a 3-wire or 4-wire Pulse Width Modulation (PWM) connector, allowing the camera’s software to speed up the fan during high-speed recording and slow it down during standby.
Technical Installation Note
Repair Level: 2 (Moderate). Replacing the fan requires opening the rear chassis.
-
Chassis Opening: You must remove the back plate of the camera. As with most PCC6K repairs, be extremely careful of the LCD ribbon cable; it is short and will snap if you pull the back plate too far away from the body.
-
Accessing the Core: The fan is usually mounted near the top of the internal frame. You may need to move the Top Button PCB slightly to clear the fan's housing.
-
The "Dust Clean-Out": While the camera is open, use a manual air blower to clear the intake and exhaust vents. If these stay clogged, the new fan will have to work twice as hard and will fail prematurely.
-
Seating the Dampers: Ensure the rubber vibration mounts are seated correctly in their recesses. If the fan touches the plastic chassis directly, the camera will vibrate, making it uncomfortable to hold and noisier to record.
Expert Advice: Before replacing the fan, check the Vents. Shine a flashlight into the top and bottom vents of the camera. If you see a "carpet" of dust, you might be able to clear it with a vacuum or compressed air (carefully) without opening the camera. If the noise persists after cleaning, then the bearings are shot and the kit is necessary.
Is your fan making a physical noise, or are you just getting a "Thermal Warning" on the screen?
