OEM Industries DASA0820R2U 80mm 4 Pin Hydro CPU

This is a pack of twenty 80mm cooling fans with hydro bearings and a 4 pin power connector. They are identified by the model number DASA0820R2U and run on 12V at .6A. The fans are designed as direct replacements for the DELL 9DVNN part used in Optiplex 790 and 990 SFF systems. No LEDs are fitted.

Compatibility check before ordering

Verify that your chassis accepts 80mm fans and that the motherboard or fan controller provides a 4 pin header. Confirm the DELL 9DVNN part number matches the unit you are replacing. Ensure the .6A current draw per fan is within the header or controller rating. The hydro bearing design suits continuous operation in compact enclosures.

Suitable for bulk maintenance of Optiplex 790

IT teams refreshing multiple small form factor workstations will value the twenty pack quantity. Builders needing a single fan, a different diameter, LED lighting or a 3 pin connector should look elsewhere. This lot is not intended for large tower coolers or radiators requiring higher static pressure.

Questions about this item

Does the lot of 20 include mounting screws or brackets for the OptiPlex 790 and 990 SFF?

The listing supplies 20 fan units only; mounting hardware for the Dell OptiPlex 790 or 990 small-form-factor chassis is not included and must be sourced separately.

Is the 80 mm hydro-bearing model the only variant offered in this 20-piece pack?

Yes, every unit in the pack is the 80 mm DASA0820R2U with a hydro bearing, 4-pin PWM connector, 12 V 0.6 A rating and no LED illumination.

What does the 0.6 A current draw mean for fan-speed control on a standard 4-pin motherboard header?

At 0.6 A the fan stays well within the typical 1 A limit of a 4-pin CPU or chassis header, allowing full PWM speed regulation without overloading the circuit.
