Fans EFB1312SHEAppearance 127×127×38mm 12V 2.76A 4500RPM 200CFM case fan
A 127 × 127 × 38 mm axial case fan delivering 200 CFM at 4500 RPM from a 12 V, 2.76 A double-ball bearing motor
- High airflow of 200 CFM moves large volumes of air through the chassis
- Double ball bearing design reduces wear for longer continuous operation
- 4500 RPM spindle speed delivers strong static pressure for dense heatsinks
- 12 V DC at 2.76 A draws predictable power from standard PSU rails
- Compact 127 × 127 × 38 mm housing suits space-constrained server and workstation builds
Delta EFB1312SHE 12V High-Airflow Fan
The Delta EFB1312SHE is a 127 × 127 × 38 mm axial case fan built for systems that need concentrated airflow in a compact frame. It suits workstations, servers and custom cooling loops where space is tight but thermal headroom must stay high.
Double Ball Bearing Build and 12 V Power
A double ball bearing supports the 4500 RPM motor while the 12 V 2.76 A input keeps wiring simple on standard headers. The sturdy steel plate housing resists vibration and the 100 % speed control via analog or serial interface lets the fan match load without extra controllers.
Replaces Lower-CFM Axial Fans in Dense Chassis
This unit steps in when a 200 CFM rating is required to push air through restrictive heat exchangers or filtered intakes. The jump is worth it when the existing fan cannot sustain pressure at speed or when bearing noise and life become limiting factors. Buyers who need a quieter low-RPM alternative or a larger frame size should look elsewhere.

Questions about this item
What is the rated voltage and current draw of this 127 mm fan?
The fan operates at 12 V DC and draws 2.76 A, so the power supply must deliver at least that current on the 12 V rail.
What mounting hole spacing and frame depth does the 127 × 127 × 38 mm frame require?
The square frame measures 127 mm per side with a 38 mm thickness; verify your case or chassis has matching 127 mm hole centres and enough clearance for the 38 mm depth.
How is the double-ball-bearing fan connected and what wiring mistake should be avoided?
It uses a standard 12 V DC power lead; connect the red wire to +12 V and the black wire to ground, taking care not to reverse the polarity which would prevent the fan from starting.
