Replacement CPU Fan for OptiPlex SFF

This new DBTLAP cooling fan is built as a direct replacement for the original cooler inside Dell OptiPlex 790, 990 and 390 small-form-factor desktops. It is intended for technicians or owners repairing a noisy or failed factory fan. The package contains one fan unit only.

Proprietary Fit and Connector Limits

The fan uses a Dell-specific mounting layout and power connector that only match the listed SFF chassis. It cannot be adapted to standard motherboard headers or other case sizes without modification. Buyers must verify the part number against their existing unit before ordering.

Single-Fan Thermal Capacity

One fan handles the thermal load of the supported OptiPlex models under normal office workloads. It lacks the airflow headroom for sustained heavy compute tasks or upgraded high-wattage processors. Systems running constant 100 percent CPU utilisation may still throttle.
