Four black 80 mm square fans with 38 mm depth

ARCTIC

ARCTIC S8038-7K 80x80x38 mm 4-pack fan

SKU CH-05C1-1HJJV

Four 80 mm PWM fans with dual ball bearings, 500-7000 RPM, 25 mmH₂O static pressure and 118.93 m³/h airflow for radiator or case cooling

  • Dual ball bearings extend lifespan and resist heat or dust
  • PWM and voltage control across 500-7000 RPM range
  • 25 mmH₂O static pressure suits radiator and case use
  • 93 m³/h maximum airflow for versatile cooling
  • 4-pin connector works with 2-pin and 3-pin headers

Four-pack 80 mm PWM fans

The ARCTIC S8038-7K ships as a set of four 80x80x38 mm fans designed for 12 V DC systems. Each unit uses a 4-pin PWM connector and runs between 500 and 7000 RPM. They suit builders upgrading CPU coolers, radiators or 2U server ventilation.

PWM range and header compatibility

Speed is regulated through PWM or voltage control across the full 500 to 7000 RPM span. The standard 4-pin plug also works on 2-pin and 3-pin headers, though control granularity depends on the motherboard implementation. A 30 cm cable gives routing flexibility inside tight chassis.

Dual ball-bearing impeller and mounting fit

Two ball bearings secure the impeller, improving durability and resistance to heat and dust. The 80x80x38 mm frame matches 2U server bays and standard 80 mm case mounts. Static pressure of 25 mmHO and airflow of 118.93 m³/h support both radiator and case-fan roles.

Questions about this item

Should I pick this 4-pack of 80 mm fans or a different quantity for my build?

The listing supplies four identical S8038-7K fans, each 80x80x38 mm with a 30 cm cable, so one pack covers up to four mounting points in a 2U server or standard case.

What does the 7000 RPM top speed actually deliver inside a case?

At 7000 RPM the fan moves up to 118.93 m³/h of air and develops 25 mmH₂O static pressure, giving strong airflow through radiators or dense heatsinks while PWM lets it drop to 500 RPM for quiet idle.

How does the 4-pin PWM connector limit control options?

The standard 4-pin header enables full PWM speed regulation from 500 to 7000 RPM on 12 V DC, and the fan also runs on 2-pin or 3-pin headers with voltage-based control instead of PWM.
