⚠️ Important Before You Buy

• Do not purchase based on GPU model alone — the same graphics card model can ship with different fans. Please verify using the dimensions and mounting hole measurements below.
• Fan replacement only — does NOT include mounting screws, heatsink, or any other components.
• Measure first: Confirm fan dimensions (85×85×12 mm) and mounting hole spacing (39×39×39 mm center-to-center) match your card before ordering.
• If you are unsure about compatibility, please contact us before purchasing.

Why Replace Your GPU Fan?

A worn or failed graphics card fan can lead to thermal throttling, reduced performance, and shortened GPU lifespan. Swapping in a fresh replacement fan is a cost-effective DIY fix that restores full airflow and helps your graphics card maintain stable, consistent performance. This fan's 4-pin PWM connector allows your card's onboard controller to automatically regulate fan speed — quieter at idle, faster when your system needs it.

Frequently Asked Questions

Q: How do I know if this 85MM GPU cooling fan is compatible with my Sapphire graphics card?

A: Compatibility is determined by the physical fan dimensions and mounting hole spacing — not just the GPU model name. Measure your existing fan: it should be 85 × 85 × 12 mm, with mounting holes spaced 39 mm center-to-center in a triangular pattern. Also confirm your card uses a 4-pin PWM power connector. The listed compatible models (R9 390X Tri-X, R9 390 NITRO, R9 290X Tri-X OC, R9 280X Vapor-X) are a guide, but always verify measurements before ordering.

Q: Does this fan come with mounting screws or a heatsink?

A: No — this listing is for the replacement cooling fan only. Mounting screws, heatsink, shroud, and all other components are not included. You will reuse the hardware already on your graphics card during the swap.

Q: What does the 4-pin PWM connector do on this GPU fan?

A: The 4-pin PWM (Pulse Width Modulation) connector allows your graphics card to automatically control the fan speed based on GPU temperature. This means the fan runs quietly under light loads and ramps up airflow when the GPU is under heavy use — helping maintain efficient cooling without unnecessary noise.

Q: Can I install this GPU replacement fan myself without professional help?

A: Yes — with basic DIY skills and the right small screwdrivers, most users can replace a GPU fan at home. Ensure your PC is powered off and unplugged before starting. Remove the graphics card, carefully detach the old fan from its mount, connect the new fan's 4-pin header, and secure it in place. If you're unsure about the process, consult a tutorial for your specific card model.
