Replacement CPU Cooling Fan

This 5 V 0.19 A four-pin fan is built as a direct replacement for the SEPA HY45Q-05A-807 4508 model. It fits compatible laptops that require the exact same part number and connector layout. Buyers who need a different voltage, pin count or form factor cannot use this unit.

Thermals Noise and Power Draw

The fan draws 0.19 A at 5 V, delivering targeted airflow to the processor heatsink during normal workloads. Operating sound stays consistent with the original component it replaces. No additional power circuitry or fan-speed profiles are required beyond the laptop’s built-in control.

Included Fan Only

The package contains one tested cooling fan and no mounting screws, thermal pads or control software. Compatibility must be verified against the part number and photos before installation. Users who expect a complete cooler assembly or extra accessories will need to source those separately.

Questions about this item

How do I install the 4-pin SEPA HY45Q-05A-807 fan and what step is often missed?

Align the four-pin connector with the motherboard header, press until it clicks, then route the cable so it cannot foul the fan blades — the step most often missed is verifying the keyed orientation before applying force.

What maintenance will the 5V 0.19A 4508 cooling fan need later?

Use compressed air to clear dust from the blades and heatsink fins every few months; the sleeve bearing is not user-serviceable, so plan to replace the whole unit when noise or vibration appears.

What limit appears first when the 807 model runs under sustained load?

The 0.19 A current ceiling caps maximum speed, so prolonged heavy thermal loads hit the fan's fixed RPM limit before the 5 V supply becomes a constraint.
