OEM Industries D07R-12T5S4 AH1 70mm 12V 0.1A 4-Pin Hydraulic CPU cooler

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.
