DVR NVR VCR Motherboard BGA CPU Cooling Fan, Dual Specification 5V Mainboard Box Fan & 12V Power Supply Cooling Fan for Surveillance Recorder Host Heat Dissipation

This professional cooling fan is customized for the internal heat dissipation system of security DVR, NVR and VCR video recording hosts, solving the overheating problem of mainboard BGA processor chips and built-in power supply modules during long-term non-stop recording work.

It provides two independent voltage versions to meet different heat dissipation positions inside the recorder: the 5V model is specially used for attaching to the main control BGA CPU chipset and internal box closed cavity to take away chip operation heat; the 12V version serves the switching power supply circuit, transformer and voltage regulator components, preventing power overheating protection and automatic shutdown.

Adopted high-quality oil bearing or double ball bearing rotor structure, the fan runs with ultra-low humming noise, will not produce obvious resonance interference to the hard disk and circuit board, and has outstanding service life to adapt to the 24/7 all-year-round working mode of monitoring equipment. The plastic frame adopts injection molding with standard mounting hole positions, directly replaces the original damaged fan without drilling or cutting the host shell.

High airflow fan blade design forms effective convection inside the closed NVR chassis, timely exhaust hot air generated by the mainboard, multiple hard disks and power unit, effectively reduce the overall internal temperature of the equipment, lower the failure rate of hard disk bad sectors, motherboard chip aging and system offline recording failure, greatly extend the service life of the whole surveillance recording device.

Widely compatible with most mainstream brand network video recorders, analog DVRs and industrial VCR storage hosts. Direct plug and play after wiring connection, no driver or debugging required. It is an essential maintenance replacement spare part for security engineering installers and monitoring equipment daily troubleshooting repair.
