Square 50 mm computer fan with black frame and copper aluminium heatsink

Graviton

Graviton DS05020R12H 5020 12V 0.25A PWM Fan

SKU CH-W9PH-VG50Z

A 50 mm by 20 mm 12 V PWM case fan with hydraulic bearing and four-wire speed control

  • 12 V PWM control adjusts speed to thermal demand
  • 5020 form factor fits 50 × 50 × 20 mm mounting spaces
  • Hydraulic bearing reduces friction for quiet operation
  • Copper and aluminium heatsink draws heat from the CPU
  • Four-wire connection enables motherboard fan-curve management

Compact 5020 PWM Fan for Tight Case Builds

The Graviton DS05020R12H is a 12 V, 0.25 A cooling fan measuring 50 by 50 by 20 mm. Its four-wire PWM interface allows the motherboard to vary speed automatically, keeping noise low when thermal load is light. The hydraulic-bearing design targets quiet, long-life operation in small-form-factor chassis. Builders fitting custom loops or cramped ITX layouts will appreciate the slim 20 mm profile.

Verify 12 V PWM Header and Mounting Spacing

Confirm that your board or fan controller provides a standard 12 V four-pin PWM header; the fan draws 0.25 A, so the header must supply at least that current. Measure the mounting holes — they follow the 50 mm square pattern — and ensure no cables or components obstruct the 20 mm depth. The copper-and-aluminium heatsink material is noted for the motor assembly, not for a separate radiator, so plan airflow direction accordingly.

Included Screws and PWM Cable Simplify Installation

The retail package supplies mounting screws and the pre-attached four-wire PWM lead, so no separate connector kit is required. CE certification indicates compliance with basic European safety standards. No software, RGB controllers or additional accessories are bundled, so fan-curve tuning is handled entirely through BIOS or your preferred fan-control utility.

Questions about this item

Does the package include mounting screws or a fan cable, or must I buy them separately?

The listing states that a package is included; no separate mounting hardware or cables are mentioned as required purchases.

Should I choose the DS05020R12H hydraulic-bearing model or the DS05020B12H double-ball-bearing model?

The R12H uses a hydraulic bearing for quieter operation, while the B12H uses a double ball bearing for longer life; pick based on your noise or durability priority.

What does the 12 V 0.25 A rating mean for actual airflow and noise inside a PC case?

At 12 V and 0.25 A the fan draws 3 W, delivering modest airflow suitable for low-heat components or auxiliary case ventilation with PWM speed control.
