SPIRE 90X90x25 mm Fan, Sleeve

This Spire 90x90x25 mm fan is a basic, reliable option for case cooling if you are looking for something simple and functional without unnecessary effects. The standard size 90 x 90 x 25 mm makes it suitable for more compact cases or as additional airflow in more confined areas. It operates at 2000 RPM, providing a good balance between airflow and noise. There is no RGB, it is entirely black, so it fits discreetly in most configurations.

What you get

With an airflow of 38 CFM, this fan is fully sufficient for intake or exhaust in smaller and medium cases where there is no room for larger fans. The noise level of 26 dBA is relatively moderate – it won't be completely silent, but it won't be unpleasantly loud in a normal environment. The sleeve bearing is typical for this class – quieter when new, especially when operating in a normal horizontal position. The 3-pin connector allows you to connect it directly to the motherboard and use basic RPM control through the BIOS (via voltage control, if the motherboard supports it). An MTBF of 30000 hours means a long enough life for standard home or office use.

• Standard size 90 x 90 x 25 mm, suitable for more compact cases and specific mounting positions.
• Operating speed of 2000 RPM, providing decent airflow without extreme noise levels.
• Airflow of 38 CFM, sufficient to improve circulation in budget and office configurations.
• Noise level 26 dBA, keeping the system relatively quiet during daily operation.
• Sleeve bearing, optimal for lower noise and normal use in standard mounting.
• 3-pin connector, allowing direct connection to the motherboard and basic RPM control.
• MTBF of 30000 hours and 24 months warranty, ensuring reasonable reliability for the product class.

Who it is suitable for

This Spire fan is a good choice if you are building a budget or office computer and need additional airflow without claims for RGB and extras. It is also suitable for older or compact cases where a 90 mm fan is specifically required. It is not the best option if you are aiming for an ultra-quiet high-end system or aggressive airflow for very hot components.

The combination of size 90 mm, 38 CFM and moderate noise at 2000 RPM makes this fan a fair, practical choice when you need simply stable case cooling without unnecessary additions.
