K2PKV / MG75090V1-C070-S9A - GPU Cooling Fan for Alienware 17 R4 R5 P31E

This GPU cooling fan is designed for compatible Alienware 17 R4 and Alienware 17 R5 gaming laptops using the K2PKV or MG75090V1-C070-S9A fan configuration. It provides dedicated cooling for the graphics processor and uses a 4-wire 4-pin connection for system-controlled fan speed and monitoring.

This is the GPU-side fan only. These systems use a separate CPU-side cooling fan, available through the related-part links below.

⭐➕ Related CPU-Side Cooling Fan — Sold Separately

This listing is for the GPU-side fan. The system also uses a separate CPU-side cooling fan identified by 4RFW1 / MG75090V1-C060-S9A.

The companion CPU fan can be purchased through either corresponding item page:

4RFW1 CPU Cooling Fan
MG75090V1-C060-S9A CPU Cooling Fan

The CPU-side and GPU-side fans are different shapes and are not interchangeable with each other.

⭐➕ Recommended Thermal Grease — Sold Separately

If the heatsink assembly must be removed during installation, completely clean away the old thermal compound and apply fresh Shin-Etsu G751 High-Performance Thermal Grease before reinstalling the heatsink.

Fresh thermal compound helps restore proper heat transfer between the GPU, CPU, heat spreaders, and cooling assembly.

⚠️ Product Appearance Notice

The item shipped may differ slightly from the listing photos. Label color, label layout, printed markings, sticker style, wire colors, and other minor cosmetic details may vary by production batch or supplier.

The actual fan will match the physical design shown, including the housing shape, mounting points, dimensions, cable configuration, connector, voltage, airflow direction, and intended compatibility. Any variation will be functionally interchangeable for the application described.

✅ Confirmed Compatibility

Several fan and thermal-module revisions were used within these laptop families. Confirm that the original GPU fan is marked K2PKV, 0K2PKV, or MG75090V1-C070-S9A and compare the housing, mounting points, cable exit, and connector before ordering.

⚙️ Fit Notes

• This is the GPU-side fan, not the CPU-side fan.
• The CPU and GPU fans have different housings, mounting points, airflow ratings, and cable routing. They cannot be substituted for one another.
• Confirm the original fan number and compare the housing shape, mounting tabs, connector, cable length, and wire order before installation.
• Do not rely on left-side or right-side descriptions alone because orientation changes depending on how the laptop is positioned.
• Some Alienware 17 R4 and R5 configurations use different fan or thermal-module revisions.
• The listing includes the fan only. The heatsink, heat pipes, thermal pads, mounting screws, and CPU-side fan are not included.
• Disconnect the AC adapter and internal battery before beginning the repair.
• Clean accumulated dust from the exhaust fins and air channels before installing the replacement fan.
• Route the fan cable exactly like the original to prevent contact with the fan blades or interference with the bottom cover.
• If the heatsink is removed, replace the thermal compound and preserve or replace thermal pads using their original thicknesses.
