Intel LGA 775 Cooler

The Spire SP520S0 is a new CPU air cooler built around a 90mm sleeve-bearing fan and an extruded aluminium heatsink. It mounts directly onto Intel LGA 775 sockets and delivers 45.18 CFM at 2400 RPM while producing 26.0 dBA of noise. The compact heatsink measures 72 by 72 by 30mm and the fan frame is 90 by 90 by 25mm.

Legacy Platform Maintainers

This cooler suits technicians servicing LGA 775 systems or builders assembling period-correct retro rigs where a low-profile aluminium tower is required. It is not for modern socket platforms, nor for high-TDP processors that demand greater thermal mass or heat-pipe designs.

90mm Sleeve Bearing Fan

The 90mm sleeve-bearing fan spins at 2400 RPM to move 45.18 CFM through the aluminium fins at a rated 26.0 dBA. This single airflow figure determines whether the cooler can handle the thermal load of the target processor.

Questions about this item

Will the SP520S0 fit my LGA 775 motherboard mounting holes?

The cooler is designed to support all new Intel LGA 775 micro-processors, so its mounting hardware aligns with the standard LGA 775 socket pattern.

Can I run the 90 mm sleeve-bearing fan at a lower speed on a 3-pin header to reduce the 26.0 dBA noise level?

Yes, reducing voltage on a 3-pin header will lower the fan speed below the rated 2400 ±10% RPM, which reduces both airflow from 45.18 CFM and the 26.0 dBA acoustic output.

How do I verify the fan is spinning at the specified 2400 RPM after installation?

Check the CPU fan speed reading in your BIOS hardware monitor or a Windows utility; it should report a value within the 2400 ±10% RPM range when the system is under load.
