Delta AFB1212SH 120 mm case fan
The Delta AFB1212SH is a 120 mm axial case fan built with a high-precision double ball bearing. It runs on 12 V at 0.8 A and spins at 3400 RPM, moving 113 CFM at 46.5 dBA. The 4-pin and 3-pin interfaces provide PWM speed control for system integration.
Suits high-airflow cooling in servers
This fan suits builders who need sustained high static pressure in dense enclosures, rackmount servers or industrial chassis where 80 000-hour bearing life reduces service intervals. It is not for silent PC builds, low-power appliances or any setup limited to 5 V or 7 V operation.
113 CFM at 3400 RPM decides fit
The 113 CFM rating at 3400 RPM is the single figure that determines whether this fan meets the thermal target. Match that airflow against the system resistance curve before ordering.

Questions about this item
What are the physical dimensions of the AFB1212SHSize fan for case mounting?
The fan measures 120 mm by 120 mm with a 25 mm thickness, matching the standard 12025 form factor for case fan mounts.
How do I connect the 4-pin PWM and 3-pin interfaces on this Delta fan during installation?
Plug the 4-pin connector into a motherboard PWM header for speed control; the 3-pin interface is an alternative for voltage control or monitoring.
When should I expect to replace the double ball bearing fan based on its rated working life?
The bearing is rated for 80,000 hours of operation; plan replacement when noise or vibration increases beyond the specified 46.5 dBA level.
