90mm Temperature-Controlled Case Fan

This 90mm case fan uses a dual ball bearing and an integrated temperature probe to adjust speed automatically between 1300 and 3600 RPM. It delivers 24.2 to 68.23 CFM of airflow while producing 16 to 42.7 dBA of noise depending on load. The black, non-LED frame suits builds that prioritise function over lighting.

Replaces Fixed-Speed 90mm Fans

The automatic regulation removes the need for manual fan curves or external controllers in compatible systems. It is a direct fit for Dell Dimension 8100 and 8200 desktops using the proprietary three-pin connector. Builders retrofitting other chassis gain variable cooling without software setup, provided the header supplies 12V at 0.55A.

Three-Pin Voltage Control Limits

The connector lacks a PWM wire so speed changes rely on voltage variation from the motherboard or the onboard thermostat. Shorting the thermostat pins forces full 3600 RPM operation at 68.23 CFM and 42.7 dBA continuously. Headers that cannot vary voltage or that limit current below 0.55A will prevent the fan from reaching its rated performance range.

Questions about this item

Will the 92 mm square frame with 32 mm depth fit my 90 mm case mount?

The fan body measures 92 × 92 × 32 mm, matching the standard 90 mm mounting hole pattern; verify your chassis has 32 mm clearance behind the mounting plane.

How do I connect the three-pin DELL connector to a standard motherboard header?

Plug the three-pin plug directly into any three- or four-pin motherboard fan header; the automatic temperature probe then regulates speed between 1300 and 3600 RPM without PWM.

When should I expect to replace the double-ball bearings?

Dual-ball bearings typically last several years of continuous use; plan replacement if noise rises above the rated 16–42.7 dBA range or airflow drops below 24.2–68.23 CFM.
