Fans 109R1212H1151 12V 0.52A 120x120x38mm case fan

SKU CH-NANH-15TG2

120 mm axial fan with double ball bearing runs at 2200 RPM on 12 V drawing 0.52 A for chassis or CPU cooling

  • 120 mm frame fits standard chassis mounts
  • 12 V / 0.52 A draws moderate power from motherboard header
  • 2 200 RPM delivers strong airflow for cooling
  • Double ball bearing extends operating life
  • 18 cm lead reaches most motherboard fan headers

120 × 120 × 38 mm double-ball-bearing axial fan

The Sanyo Denki 109R1212H1151 is a 12 V DC case fan that draws 0.52 A at full speed. Its 3-pin connector plugs directly into a standard motherboard header and provides RPM feedback. The 18 cm lead reaches most chassis fan headers without extension cables.

Builders needing reliable long-term airflow

The double ball bearing suits continuous duty and high ambient temperatures better than sleeve alternatives. Systems that require PWM speed control or a 4-pin header will not gain automatic curve control from this 3-pin model. Buyers who want more storage for fan curves in hardware should look at PWM variants.

Steady 2200 RPM output under sustained load

At constant 12 V the motor holds 2200 RPM without the speed decay common in sleeve-bearing units after warm-up. Ball-bearing construction keeps acoustic signature stable over thousands of hours. The fixed-voltage design means airflow scales linearly with any external voltage reducer the builder chooses.

Questions about this item

What motherboard header does the 3P plug on this 109R1212H1151 fan connect to?

The fan uses a standard three-pin connector that fits any 12 V motherboard fan header; the third pin provides speed measurement so the board can report the 2200 RPM reading.

Will the 38 mm depth of this 120x120 mm axial fan interfere with taller CPU coolers or radiators?

At 38 mm thick the unit is deeper than slimmer models; measure the clearance between your cooler or radiator and the side panel before mounting to ensure it fits.

How can I confirm the double ball bearing fan is spinning at the rated 2200 RPM after installation?

Connect the 3P plug to a motherboard header and monitor the RPM in BIOS or a hardware-monitoring utility; a steady reading near 2200 RPM indicates normal operation.
