Silence Your Build,
Externally.
The BC12 External Radiator is engineered for compact chassis and high-performance workstations. By moving heat dissipation outside the case, it solves the thermal constraints of Mini-ITX builds while maintaining whisper-quiet operation.
What is the BC12 External Radiator?
The Ococoo BC12 is a standalone external liquid cooling module designed to decouple thermal management from PC chassis limitations. Unlike internal radiators, the BC12 External Radiator utilizes ambient air unrestricted by case airflow, significantly lowering coolant temperatures (Delta T) for high TDP components like RTX 4090 GPUs and overclocked CPUs.
It features an integrated pump-reservoir combo unit, simplifying the loop for SFF (Small Form Factor) users who lack internal space for traditional water cooling components.

Distributor & Technical FAQ
What is the Minimum Order Quantity (MOQ) for wholesale pricing?
For standard units, we support low MOQs to help partners test the market. For OEM customizations (logo/color), please contact our sales team for specific tier pricing.
Can the pump speed be adjusted?
Yes, the integrated pump typically supports PWM control, allowing users to balance flow rate and noise levels via their motherboard bios or controller.
How is the unit packaged for shipping?
Each BC12 is encased in high-density foam within a reinforced cardboard box to prevent fin damage or tank cracking during transit.
Do you provide leak testing reports?
Every unit undergoes a pressure test before leaving the factory to ensure the integrity of the radiator core and pump seals.
What is the warranty period for B2B orders?
We provide a standard warranty covering manufacturing defects. Extended warranty terms can be negotiated for bulk contracts.
Does it come with fans included?
Standard configuration usually excludes fans to allow users to choose their preferred static pressure fans, but we can bundle fans for OEM orders.
