Zyvpee 70 mm 4-pin case fan

The Zyvpee DV07020B12U AS02 is a 70 by 20 millimetre case fan with a four-pin power connector and ball bearing. It runs on 12 volt DC power at 0.7 ampere and has no LED lighting. The black frame suits standard chassis mounting points.

Replaces worn 70 mm three-pin fans

Swapping a failed or noisy 70 mm three-pin unit for this four-pin model restores PWM speed control. The upgrade is worth it when the motherboard header supports four-pin regulation and the existing fan can no longer maintain target temperatures.

Simple four-screw installation

The fan mounts with four screws into any 70 millimetre cut-out and the keyed four-pin plug prevents reversed connection. Common issues arise when the header is set to voltage mode instead of PWM or when cable routing blocks the impeller.

Questions about this item

Will the 70*20mm frame fit my case's 70mm fan mount?

Yes, the 70mm square frame and 20mm thickness match standard 70mm mounting holes used on many compact cases and CPU coolers.

How do I connect the 4-pin connector so the motherboard controls speed correctly?

Plug the 4-pin plug into a 4-pin PWM header on the motherboard; the fourth wire carries the PWM signal that lets the board vary the 12V 0.7A fan speed automatically.

When should I expect to replace the ball-bearing fan?

Ball bearings typically run for years; replace the fan if you hear grinding, feel vibration, or notice the RPM dropping well below its normal range.
