80mm Ball-Bearing Server Fan

The iStarUSA DD-FAN80 is an 80mm ball-bearing cooling fan built for server and rack-mount enclosures. It runs on 12V DC power and spins at 3200 RPM with a ten-percent tolerance. The unit measures 3.15 by .98 by 3.15 inches and carries RoHS compliance. It is suited for administrators who need a direct-replacement airflow device in standard 80mm mounting holes.

12V DC Input and Fixed Speed Limit

The fan operates only from a 12V DC source and delivers a single fixed speed of 3200 RPM. There is no PWM or voltage-control header mentioned, so the motor cannot be slowed down or monitored by the host system. Builds that require variable-speed control, soft-start sequencing or tachometer feedback cannot use this model without external circuitry. The ball-bearing design targets 80000 hours of rated life at that constant speed.

80mm Form Factor Decides Fit

The 3.15-inch square frame with .98-inch depth is the sole dimensional constraint that determines whether the fan fits a given chassis. If the mounting pattern or clearance differs from the standard 80mm footprint the part will not install. No adapter brackets or alternative mounting hardware are included. Verify the exact hole spacing and depth allowance in the target enclosure before purchase.

Questions about this item

Should I choose the 80 mm ball-bearing version or a different size for my server chassis?

This model is an 80 mm ball-bearing fan rated for 80,000 hours; select it when your chassis has 80 mm mounting holes and you need long-life cooling.

What does the 3200 RPM rating mean once the fan is installed in a real server?

At 12 V DC the fan spins at 3200 RPM ±10 %, delivering strong airflow through the 3.15" × .98" × 3.15" frame to keep components cool.

The fan uses a 12 V DC input — what does that cap in practice?

The 12 V DC supply limits the motor to its rated 3200 RPM, so airflow stays within the designed 80,000-hour lifespan envelope.
