The “3 Pin H87 Plus Fan” is a common search term for those building or upgrading their PC systems. It reflects the desire to understand how to properly connect fans to the motherboard, specifically focusing on the 3-pin fan headers found on motherboards like the H87 Plus. This article delves into the intricacies of this setup, addressing common questions and providing clear guidance for optimal cooling solutions.
3-Pin Fan Headers Explained
Motherboards, including the H87 Plus, feature dedicated headers for connecting cooling fans. These headers typically come in two varieties: 3-pin and 4-pin. The 3-pin header, as the name suggests, has three pins, each with a specific function:
- Ground: Provides a ground connection for the fan.
- +12V: Supplies the fan with 12 volts of power.
- Sense: This pin allows the motherboard to monitor the fan’s rotational speed (RPM).

Connecting a 3-Pin Fan to an H87 Plus Motherboard
Connecting a 3-pin fan to your H87 Plus motherboard is straightforward. The fan header usually has a small plastic clip that secures the fan connector. Align the connector with the header, ensuring the small arrow on the connector matches the +12V pin on the header. Gently push the connector until it clicks into place.
Important Note: Forcing the connector can damage the header or the fan.

3-Pin vs. 4-Pin Fans: What’s the Difference?
While both 3-pin and 4-pin fans provide cooling, they differ in their control mechanisms:
- 3-Pin Fans: These fans operate at a fixed speed determined by the voltage supplied by the motherboard.
- 4-Pin Fans: These fans feature Pulse Width Modulation (PWM), allowing for more precise speed control based on temperature readings.
The H87 Plus motherboard typically supports both 3-pin and 4-pin fans. However, the fan control method will depend on the type of header used.
