CPU Cooling Fan HF-690 Price in Bangladesh

A CPU Cooling Fan HF-690 is an essential component in any computer system, especially for high-performance setups or gaming PCs. Its main function is to draw heat away from the processor and disperse it efficiently, preventing overheating and ensuring optimal system performance. A quality cpu fan extends your processor’s lifespan and enhances stability during intensive tasks. In the context of Bangladesh’s rising demand for computing hardware, finding a reliable and affordable cpu fan has become crucial. Whether you’re building a PC or upgrading your system, understanding the specifications, build, and benefits of this product helps in making the right buying decision.

Specification

Fan Blades

The fan blades in this devices are engineered for maximum airflow and low noise operation. Typically made from durable plastic or composite materials, these blades are aerodynamically shaped to ensure smooth air movement. The number of blades usually ranges between 7 to 11, and their design plays a crucial role in pushing heat away from the heat sink. Efficient blade angles enhance cooling efficiency, reduce turbulence, and maintain quiet operation during heavy loads or prolonged use.

Heat Sink (Fins)

The heat sink is composed of thin, layered metal fins—usually aluminum or copper—designed to spread heat rapidly from the base plate to the surrounding air. The CPU Cooling Fan HF-690 increases the surface area, allowing heat to dissipate more efficiently. Their compact yet spacious arrangement facilitates unrestricted airflow from the fan. In Bangladesh’s warm climate, a high-density heat sink ensures stable processor temperature even during power-intensive tasks like gaming or rendering.

Base Plate

The base plate is the interface between the processor and the cooler. Made from high-conductivity materials such as copper or aluminum, it ensures rapid thermal transfer. A polished or nickel-plated surface allows maximum contact with the CPU’s integrated heat spreader (IHS), improving cooling performance. For optimal results, a thermal paste is applied between the CPU and base plate. The efficiency of this component largely determines how effectively heat is pulled away from the processor.

Heat Pipes

Heat pipes serve as the bridge that carries thermal energy from the base plate to the heat sink. Most cooling fans feature 2 to 6 copper heat pipes filled with a liquid that vaporizes when heated, moves heat efficiently to the fins, and then condenses back. Their placement and number directly affect performance. Good quality heat pipes with direct contact to the CPU ensure stable cooling even under overclocked conditions or high thermal stress environments.

Fan Motor (Hub)

The fan motor, located at the center hub, powers the fan blades and is often equipped with Pulse Width Modulation (PWM) control. PWM support allows automatic adjustment of fan speed based on CPU temperature, reducing unnecessary noise and power usage. A reliable brushless DC motor ensures consistent performance with minimal friction. The motor’s build quality directly impacts durability, speed control, and energy efficiency in long-term usage.

Bearing Type

The bearing type used in a CPU cooling fan plays a crucial role in noise level, lifespan, and smoothness. Common types include sleeve, rifle, hydraulic, and dual ball bearings. Sleeve bearings are more affordable but less durable, while hydraulic and ball bearings offer higher performance and longer lifespan. For Bangladeshi consumers looking for a balance between cost and performance, hydraulic bearings offer a good middle ground with minimal maintenance needs.

Fan Frame of CPU Cooling Fan HF-690

The fan frame, also known as the housing, supports the structure and ensures proper alignment of the blades and the motor. Usually constructed from heat-resistant ABS or PBT plastic, it provides rigid support while minimizing vibrations. It is designed for airflow optimization and easy installation within the CPU cooler assembly. A well-designed housing minimizes air leakage and directs airflow over the heat sink for better thermal performance.

Mounting Brackets / Clamps

Mounting brackets or clamps are essential for securely attaching the device to the motherboard. They are usually made from steel or reinforced plastic and are compatible with major processor sockets from Intel and AMD. A universal mounting system simplifies installation and enhances compatibility for system builders. In Bangladesh, where DIY PC building is growing in popularity, these easy-to-install brackets offer convenience and versatility.

Power Connector (3-pin/4-pin)

The power connector links the cooling fan to the motherboard. A 3-pin connector provides basic power and speed monitoring, while a 4-pin connector adds PWM support for dynamic speed control. Most modern motherboards and fans in the Bangladeshi market support 4-pin connectors. Choosing a 4-pin fan offers better temperature regulation and quieter operation, making it ideal for everyday use and gaming systems alike.

RGB / LED Lighting (Optional)

For users who value aesthetics alongside performance, many CPU Cooling Fan HF-690 include RGB or LED lighting features. These lights are usually customizable and can sync with motherboard lighting software. Whether static or dynamic, RGB lighting enhances the overall look of a gaming PC. Though optional, RGB lighting is gaining popularity in Bangladesh among younger tech enthusiasts seeking both function and style in their builds.
