Black square 80 mm axial fan with clear plastic blades and four-wire connector

Haywards

Haywards 80 mm 12 V 7800 RPM axial case fan

SKU CH-S0Q7-MFZ74

An 80 mm axial case fan delivering 7800 RPM with a 4-pin PWM interface for computer cooling

  • High airflow with 7800 RPM axial design
  • Low friction from two ball bearing construction
  • PWM speed control via 4-pin interface
  • Compact 80x80x38 mm footprint fits cases
  • CE certified for safety compliance

80 mm 12 V axial case fan

This 80 mm axial fan runs on 12 V and spins at 7 800 RPM to move air through a computer case. It uses a four-wire PWM interface so the motherboard can adjust speed based on temperature. The frame measures 80 by 80 by 38 mm and draws 1.76 A at full speed. A two-ball bearing supports the rotor for long service life.

Thermals noise and power draw

At the rated 7 800 RPM the fan produces an airflow of 19.4 CFM while the motor consumes approximately 12 W from the 12 V rail. The supplier specifies a noise level of 54 dB from the radiator area under normal operation. Operating voltage can range from 7.0 V to 13.4 V, allowing lower speeds and quieter running when full flow is not needed. The four-pin connector reports speed back to the system for monitoring.

Behaviour under sustained load

The two-ball bearing is rated for 70 000 hours of continuous running, indicating durability during extended high-speed operation. PWM intelligent temperature control adjusts the rotor speed automatically as internal temperatures rise, keeping airflow matched to the thermal load. Because the design targets high rotational speed, acoustic output remains noticeable even when the fan is not at its maximum 18 000 RPM capability. The plastic frame and impeller maintain dimensional stability throughout prolonged use.

Questions about this item

How do I mount the 80 mm fan in my case and what step is often missed?

Align the 80×80 mm frame with the case mounting holes, insert the four screws through the fan flange into the case, then connect the 4-pin PWM header so the motherboard can control speed; the step most often missed is plugging in the 4-pin connector after the screws are tight.

What maintenance will the two ball bearing fan need and when should I plan a replacement?

The double ball bearing is rated for 70000 hours of operation; no lubrication is required, but after that period expect increased noise or speed drop, so plan a straight swap with another 80 mm 12 V unit.

At what point does the 7800 RPM fan hit its thermal or noise limit during sustained load?

At full 7800 RPM the fan produces 54 dB of radiator noise and moves 19.4 CFM; sustained operation at that speed is the practical limit before noise becomes intrusive and airflow gains diminish.
