⭐➕ Matching GPU-Side Cooling Fan — Sold Separately

This listing is for the CPU-side fan. The matching GPU-side fan uses part number K2PKV or MG75090V1-C070-S9A:

• ✔️ K2PKV GPU-Side Cooling Fan
• ✔️ MG75090V1-C070-S9A GPU-Side Cooling Fan

The CPU and GPU fans are shaped differently and are not interchangeable with each other.

⭐➕ Recommended Thermal Compound

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

✅ Confirmed Compatibility

Fan revisions can vary within the same laptop family. Confirm the original part number, housing shape, mounting points, connector, cable routing, and installation position before ordering.

⚙️ Fit Notes

• This is the CPU-side fan, not the GPU-side fan.
• Do not select a replacement using “left” or “right” descriptions alone; viewing orientation differs between sellers and service diagrams.
• Confirm the original fan number, housing outline, screw locations, cable exit, connector, wire count, and wire order.
• Alternate production revisions may have different label designs, printed current ratings, or supplier markings.
• The CPU and GPU fans are not interchangeable even though they are installed in the same system.
• This listing includes the fan only. Reuse the original heatsink, heat pipes, screws, and thermal pads when serviceable.
• Disconnect the AC adapter and internal battery before installation.
• Route the fan cable exactly as originally installed so it cannot contact the fan blades or become pinched beneath the heatsink.
• Clean dust from the heatsink fins and exhaust vents before fitting the replacement fan.
• If the heatsink is removed, replace the thermal compound and preserve the location and thickness of every original thermal pad.
