Fans R1G175-RC02-11/A01 48V 0.8A 175mm centrifugal case fan

SKU CH-J04H-R54S5

A 175 mm centrifugal case fan running on 48 V DC with a 4-pin connector and oil bearing rated for 100000 hours

  • Centrifugal airflow targets hotspots inside tight chassis
  • 48 V 0.8 A draw keeps power budget low
  • 175 mm square frame fits standard mounting points
  • Oil bearing rated for 100000 hrs continuous use
  • 4-pin interface enables PWM speed control

Product Identity

The Fans R1G175-RC02-11/A01 is a 48V DC centrifugal fan built for computer case cooling. It uses an oil bearing rated for 100000 hrs of operation and connects via a 4PIN power interface. The unit measures 175x175mm and is supplied new in its package.

Suitability

This fan suits builders who need a centrifugal airflow design at 48V for industrial or specialised case cooling. It is not for systems that require a different supply voltage or a different mounting footprint. Buyers needing a standard axial blade profile should look elsewhere.

Decisive Specification

The 48V 0.8A centrifugal motor with 4PIN control is the single specification that determines fit. Only systems providing 48V DC and a matching 4PIN header can power and regulate this unit correctly.

Questions about this item

Does this 175 mm centrifugal fan need a motherboard with a 4-pin PWM header to run?

Yes, the fan uses a 4-pin power interface so it connects to a standard 4-pin PWM header on the motherboard or a compatible fan controller.

Can the 48 V 0.8 A input be supplied by a typical 12 V PC power supply?

No, the fan requires a 48 V DC source; a standard 12 V PC power supply will not provide the correct voltage.

How can I confirm the fan is operating correctly after installation?

Monitor the RPM reading in BIOS or fan-control software; a steady signal from the 4-pin tach wire shows the oil-bearing motor is spinning as intended.
