Casing Fan Price in Bangladesh

Does your PC get hot and loud while gaming or rendering? The right casing fans cool it down and quiet it too.

This page covers casing fan price in Bangladesh with a buying guide. We explain sizes, airflow, connectors, RGB and setup. Then you choose fans that fit your case.

What Is a Casing Fan and Why Does Your PC Need One?

A casing fan mounts inside your PC case. Some call it a case fan or casing cooler. It pulls cool air in and pushes hot air out.

Your CPU, graphics card and motherboard all make heat. Without airflow, that heat stays trapped inside the case.

Trapped heat makes parts slow down to protect themselves. Over time, it also shortens their life.

• Lower CPU and GPU temperatures
• Better gaming performance with less thermal throttling
• Quieter PC because fans can spin slower
• Longer life for parts in hot weather
• Cleaner look with RGB or ARGB lighting

Key Takeaways

• 120mm and 140mm casing fans suit most cases.
• PWM fans adjust speed automatically and stay quieter.
• Never plug ARGB fans into RGB headers.
• Front intake and rear exhaust is the classic layout.
• Dust filters matter a lot in Bangladesh.

What Affects Casing Fan Price in Bangladesh?

Casing fan prices vary widely. Two fans of the same size can differ a lot in cost.

Knowing what drives the difference helps you pay for what matters.

Brand, warranty and pack size also change the price. Three-fan kits often cost less per fan than singles.

Prices also shift with dollar rates and import costs. Check the latest price before ordering.

Types of Casing Fans Available in Bangladesh

The market offers several casing fan types. Each suits a different build and budget.

Non-RGB Casing Fans

These fans focus only on cooling. They are simple, reliable and often quieter at the same budget.

They suit office PCs, workstations and builders who prefer a clean look.

RGB Casing Fans

RGB casing fans light up in one colour at a time. They use a 12V 4-pin lighting header.

They add style to budget gaming builds without complex setup.

ARGB Casing Fans

ARGB, or addressable RGB, fans control each LED separately. They create rainbow waves and custom effects.

They use a 5V 3-pin header. Most sync with motherboard lighting software.

Casing Fan Kits with Controller

Many brands sell three-fan kits with a hub and remote. These help when your motherboard lacks enough headers.

Kits also keep lighting and speed in sync across all fans.

Reverse Blade Casing Fans

Reverse blade fans show the clean side from both directions. They suit glass-sided cases with bottom or side intake.

Daisy-Chain Casing Fans

Some fans link together with clip-on connectors. One cable then runs to the motherboard.

This reduces cable clutter in the back of the case.

Casing Fan Size Guide: 120mm vs 140mm vs 200mm

Check your case's fan mounts before buying. Most cases list supported sizes in the manual.

Is a 120mm Casing Fan Enough?

For most mid tower cases, yes. Three 120mm intake fans cool most gaming builds well.

When to Choose 140mm Casing Fans

Choose 140mm if your case supports it. Larger blades move the same air at lower speed.

That means a quieter PC under the same load.

Airflow vs Static Pressure Casing Fans: Which One Do You Need?

Casing fans come in two main designs. The right one depends on where you mount it.

Airflow is shown in CFM. Static pressure is shown in mmH2O. Higher numbers mean stronger performance.

Using an AIO liquid cooler? Put static pressure fans on the radiator.

Using a solid glass front panel? Static pressure fans help pull air through side vents.

Casing Fan Speed, Noise and Bearing Types Explained

RPM shows fan speed. Higher RPM moves more air but makes more noise.

Noise appears as dBA on spec sheets. Lower numbers mean a quieter fan.

A wide RPM range is useful. The fan stays silent at idle and ramps up while gaming.

Casing Fan Bearing Types

The bearing decides lifespan and noise. It is one of the biggest quality differences.

Fluid dynamic and hydro bearings suit most buyers. They last long and stay quiet.

3-Pin vs 4-Pin PWM Casing Fan: Which Connector Is Better?

The connector decides how your PC controls fan speed.

• 3-pin DC: speed changes by voltage, less precise
• 4-pin PWM: motherboard controls speed smoothly and precisely
• Molex or SATA power: runs at full speed with no control

PWM casing fans spin slowly at idle and faster under load. This keeps your PC quiet most of the time.

How to Set a Fan Curve

Open your BIOS fan settings, often called Q-Fan or Smart Fan. Set lower speeds at low temperatures.

Raise speed gradually as temperatures climb. This balances cooling and noise.

Fan Headers, Hubs and Splitters

Count the fan headers on your motherboard. Most boards have two to five.

Adding many fans? Use a PWM fan hub or splitter. Check the header's power limit first.

A powered hub takes energy from SATA power. It protects the motherboard header from overload.

RGB vs ARGB Casing Fan: Lighting, Sync and Safety

Lighting looks great, but the connectors differ. Mixing them can damage your fans.

Never plug a 5V ARGB fan into a 12V RGB header. It can burn the LEDs instantly.

Syncing Lighting With Your Motherboard

Popular sync tools include ASUS Aura Sync and MSI Mystic Light. Gigabyte RGB Fusion and ASRock Polychrome work too. Check your board's lighting headers first.

No lighting header? Choose a kit with its own controller and remote.

How Many Casing Fans Does Your PC Need?

More fans are not always better. Balance and direction matter more than numbers.

A graphics card with high power draw needs more fresh air. Add front intake before adding more exhaust.

Best Casing Fan Setup for Airflow

Cool air should enter from the front and bottom. Hot air should leave from the top and rear.

• Front fans: intake
• Rear fan: exhaust
• Top fans: exhaust
• Bottom fans: intake, if your case supports them

Positive vs Negative Pressure

Positive pressure means more intake than exhaust. Air leaves through small gaps, so less dust enters.

Negative pressure means more exhaust than intake. Dust then sneaks in through unfiltered gaps.

A slightly positive setup works best in dusty rooms. Use filtered intakes with it.

How to Check Casing Fan Direction

Most fans have small arrows on the frame. One shows airflow direction, the other shows spin.

The open side with the logo usually pulls air in. The side with the frame struts pushes air out.

Best Casing Fan Brands in Bangladesh

Many trusted brands sell casing fans in Bangladesh. Each offers basic and lighting lines.

Budget Casing Fan Brands

PC Power, Gamdias and Montech suit first builds and office upgrades. They offer lighting at an easy level.

Performance Casing Fan Brands

Arctic, Thermalright and Noctua focus on cooling and low noise. They suit workstations and quiet gaming rigs.

Premium RGB Casing Fan Brands

Lian Li, Corsair and NZXT focus on design and software. They suit showcase builds with glass panels.

Which Casing Fan Is Right for You?

Different users need different fans. Match the fan to your daily work.

Freelancers running renders overnight should choose long-life bearings. Ball or fluid dynamic bearings suit 24/7 use.

Casing Fan vs CPU Cooler vs Liquid Cooler

These parts work together, but they do different jobs.

A great CPU cooler still needs casing fans. Without fresh air, it only recycles hot air.

How to Install a Casing Fan: Step by Step

Installing a casing fan takes a few minutes. Follow these steps carefully.

1. Shut down and unplug the PC
2. Touch the metal case to release static
3. Decide intake or exhaust for each position
4. Line up the fan with the mount holes
5. Fix it with the screws or clips provided
6. Connect the fan to a header, hub or controller
7. Connect ARGB or RGB cables to the right header
8. Tidy cables away from other fan blades
9. Power on and check every fan spins

Set your fan curve in BIOS after installation. Then check temperatures while gaming.

Casing Fan Maintenance in Bangladesh's Heat and Dust

Room temperatures rise a lot in summer. Good airflow keeps parts safe during long gaming sessions.

Consider an extra exhaust fan if temperatures stay high.

Dust and Humidity

Dust builds up fast in Dhaka and many towns. It blocks filters, slows fans and traps heat.

Humidity can also make dust stick to blades.

• Clean dust filters every two to four weeks
• Blow out fans and heatsinks every few months
• Hold blades still while blowing air on them
• Keep the PC off the floor

Load-Shedding

Sudden shutdowns do not harm fans, but they stress other parts. A UPS gives time to shut down safely.

Casing Fan Warranty and After-Sales Support

Most branded casing fans carry an official warranty. Terms vary by brand and model.

Keep the box and invoice for claims. Warranty often covers motor and LED faults, not physical damage.

Premium bearings also mean fewer faults over time. That saves repeat buying.

Common Mistakes When Buying Casing Fans

• Installing all fans as intake or all as exhaust
• Plugging ARGB fans into RGB headers
• Buying 3-pin fans when you want quiet PWM control
• Ignoring the case's supported fan sizes
• Skipping dust filters in a dusty room
• Overloading one fan header without a hub
