SKU CH-DHV1-H2MMW

A 1.7 cm axial micro fan with 5 V three-wire power and waterproof construction

  • 7 cm micro footprint fits ultra-compact builds
  • 5 V 3-wire PWM enables precise speed control
  • Waterproof construction resists moisture in harsh environments
  • Axial airflow design cools tight CPU spaces

Micro Mini Axial CPU Cooler 1.7 cm

The Fans 1703 UF5H5-503 is a 1.7 cm micro mini axial cooling fan designed for CPU air cooling. It operates on 5 V power through a 3-wire connection and features a waterproof construction. This compact cooler suits space-constrained builds requiring small-form-factor thermal management.

Builders needing low-voltage 5 V cooling

This fan suits systems with 5 V fan headers and tight clearances where a 1.7 cm axial unit fits. It is not for builds that lack a 5 V header or require larger airflow capacity than a micro mini fan can deliver. Buyers needing higher static pressure or larger frame dimensions should consider other cooling solutions.

Highlights

  • 7 cm micro footprint fits ultra-compact builds
  • 5 V 3-wire PWM enables precise speed control
  • Waterproof construction resists moisture in harsh environments
  • Axial airflow design cools tight CPU spaces

Questions about this item

What motherboard header does the 5 V 3-wire fan connect to?

The fan uses a standard three-wire 5 V connector that plugs into a 5 V fan header on the motherboard or a compatible fan controller.

Will the 1.7 cm UF5H5-503 fit in the same mounting holes as my existing 1703 cooler?

Both models share the 1703 frame size, so the mounting pattern is identical and the UF5H5-503 can replace the older unit directly.
