Compact 70 mm hydraulic fan for tight builds

This 70 mm square fan uses a hydraulic bearing and a 4-pin PWM connector for speed control. It draws 0.1 A at 12 V and fits standard 7015 mounting holes. The black frame has no LED lighting. It serves as a direct-replacement CPU or case fan in small-form-factor systems.

Replaces worn or noisy 70 mm 3-pin or 4-pin fans

Swap this unit in when an existing 7015-size cooler rattles, spins down or fails to report speed. The hydraulic bearing reduces friction compared with sleeve types, and the fourth wire restores PWM control and tachometer feedback. The jump is worth it when the current fan no longer maintains target temperatures or reports zero RPM to the BIOS.

Verify 70 mm mounting spacing

Measure the screw-hole centres on your heatsink or chassis to confirm 70 mm compatibility. Ensure the motherboard or fan controller provides a 4-pin header; a 3-pin header will run the fan at full speed without speed reporting. Check that 15 mm thickness clears adjacent components and cable routing.

Questions about this item

Will the 70mm square frame with 15mm depth fit my chassis fan mount?

The fan measures 70mm square and 15mm thick, so verify your case has a 70mm mounting pattern and at least 15mm clearance behind the grille.

How do I connect the 4-pin PWM header correctly?

Align the keyed 4-pin connector with the motherboard CPU_FAN or SYS_FAN header; the notch prevents reverse insertion, which is the common mistake.

Does the hydraulic bearing need periodic oiling?

The sealed hydraulic bearing is maintenance-free for the fan's service life; no lubrication is required.
