Replacement CPU Cooling Fan

This is a new replacement CPU cooling fan for laptops using the SUNON MG75091V1-C250-S9A part. It suits owners of 2021 RTX30 series machines needing a direct 12V 4PIN swap. Each unit is tested before shipping to confirm operation. Verify the part number against your original fan before ordering.

12V 4PIN Interface Limits

The fan connects via a 12V 4PIN header, so it only fits laptops with that exact power and control interface. Systems using 5V, 3-pin or proprietary connectors cannot use this unit. The four-pin design enables PWM speed control where the motherboard supports it. Mismatched voltage or pin layout will prevent installation or damage the component.

RTX30 2021 Compatibility Headroom

This part targets 2021 RTX30 laptop platforms that specify the MG75091V1-C250-S9A model. It covers single-fan CPU cooling duties for those chassis designs. It does not address GPU cooling, dual-fan layouts or newer GPU generations. Buyers needing a different part number, higher airflow rating or multi-fan assembly must source an alternative match.

Questions about this item

Should I pick the 12V or 30 model for my RTX30 laptop?

The 12V rating matches the SUNON MG75091V1-C250-S9A fan used in RTX30 2021 laptops; the 30 in the title refers to the GPU series, not a voltage option.

What does the 12V rating mean once the fan is installed?

It draws 12V from the laptop's 4-pin header, so the motherboard controls speed and power without an external adapter.

How does the 4-pin connector limit fan control?

The 4-pin PWM interface lets the system vary speed precisely; the header caps voltage at 12V, so the fan cannot exceed its rated input.
