12V 3.8A 97mm 4-Pin Radiator Blower Fan for Alienware X51 R2 R3

This 12V high-output centrifugal blower fan is designed to move air through the compact processor liquid-cooling radiator used in compatible Alienware X51 systems. It uses a four-wire 4-pin connection for system-controlled speed regulation and fan-speed monitoring.

MVDCV, 0MVDCV, MVDCV-A00 and 9BMB12P2J619 identify the same fan configuration. This listing includes the fan shown only. The radiator, pump, cold plate, hoses and complete processor cooling assembly are not included.

⚠️ Critical Fan-Only Compatibility Notice

This listing is for the blower fan only. It is not a complete liquid-cooling system and cannot convert a standard air-cooled computer to liquid cooling by itself.

Before ordering, verify all of the following:

• The installed fan is marked MVDCV, MVDCV-A00 or 9BMB12P2J619.
• The fan is rated for 12V DC and 3.8A.
• The housing is the 97mm × 33mm centrifugal-blower design.
• The cable has four wires and the matching 4-pin connector.
• The connector keying, wire order and cable length match.
• The airflow outlet and mounting-hole locations match the installed fan.
• The computer already contains the compatible liquid-cooling radiator assembly.

A standard axial case fan, graphics-card blower or generic 97mm blower should not be substituted solely because its dimensions are similar. Connector wiring, speed control, sensor output, mounting points and airflow direction must all match.

✅ Confirmed Compatibility

Direct Liquid-Cooled Application

✔️ Alienware X51 R3
✔️ Alienware X51 R3 regulatory model D05S
✔️ Alienware X51 R3 regulatory type D05S003
✔️ X51 R3 configurations equipped with the processor liquid-cooling assembly
✔️ X51 R3 systems using MVDCV or 9BMB12P2J619
✔️ X51 R3 systems using the 5FGKT / 05FGKT liquid-cooling assembly
✔️ X51 R3 systems using the G0FC5 processor thermal module when only the blower fan requires replacement

Conditional X51 R2 Application

✔️ Alienware X51 R2 regulatory model D05S
✔️ Alienware X51 R2 regulatory type D05S002
✔️ X51 R2 systems already fitted with the compatible X51 R3-style liquid-cooling radiator assembly
✔️ X51 R2 systems in which the installed blower is specifically marked MVDCV, MVDCV-A00 or 9BMB12P2J619

The standard air-cooled X51 R2 configuration does not use this fan. Compatibility with an X51 R2 requires an existing compatible liquid-cooling conversion or installed cooling assembly.

⚙️ Fit Notes

• Shut down the computer and disconnect the external power adapter and all attached cables before opening the enclosure.
• Press and hold the power button briefly after disconnecting power to discharge residual power.
• Record the installed fan orientation, airflow direction and cable routing before removal.
• Disconnect the fan by holding the connector housing rather than pulling on the wires.
• Retain the existing mounting screws and hardware for installation of the replacement fan.
• Clean accumulated dust from the radiator fins while the fan is removed.
• Install the blower in the same orientation so its outlet directs air through the radiator correctly.
• Route the cable through the existing guides and keep it away from the impeller.
• Confirm that the 4-pin connector is fully seated before reassembling the computer.
• After startup, verify that the fan spins, changes speed under load and does not produce a fan error.
• If overheating continues after fan replacement, inspect the radiator for blockage and verify that the liquid-cooling pump is operating.
