Jonsbo FR-505 ARGB 120mm Casing Fan

The FR-505 is Jonsbo's most popular desktop fan globally. It is a 120mm ARGB case fan with a three-sided infinity mirror frame and transparent blades.

The FR-505 features a classic axis millennium mirror, three-sided infinite mirror lighting with 26 RGB lamp beads, PWM intelligent temperature control, and male-female connectors for daisy-chaining multiple fans.

FR-505 Black (Positive Blade) — Available at PCB Store

The black version suits dark-themed PC builds. It pairs perfectly with a black casing and dark PC motherboards. Strong airflow with low noise at idle.

FR-505 White (Positive Blade) — Available at PCB Store

White buildings are trending in Bangladesh. The white FR-505 delivers the same specs in a clean white frame. Pairs well with white casings and white air cooler setups.

FR-505 Reverse Blade — Available at PCB Store

The reverse-blade version provides an airflow volume of 80.19 m³/h through inverted rotor blades. Use reverse-blade fans at the front intake for smoother airflow direction in custom builds.

FR-505 3-Pack — Best Value for BD Builders

Most PC cases support three to six fans. The 3-pack gives you matching fans at a lower per-unit cost. Ideal for filling a mid-tower or full-tower computer casing.

Jonsbo Performance Fan (Non-RGB) — For Silent Builds

Not every build needs lighting. For workstations and silent office components, Jonsbo makes non-RGB performance fans. Jonsbo fans balance air pressure, air volume, noise, and lifetime — even without lighting effects.

These fans are ideal for:

• Office PCs and workstations
• Budget PC build setups
• Secondary fans in gaming rigs

Key Features of Jonsbo Casing Fan

Understanding what you pay for is important. Let us break down every key feature of Jonsbo casing fans.

ARGB Infinity Mirror Effect — Jonsbo's Signature Look

Most case fans have LEDs on the blade hub only. Jonsbo does it differently.

The FR-505 features an illuminated infinity effect frame and transparent fan blades with digitally addressable RGB lighting located on the edge of the fan.

The result is a three-sided mirror effect. The light bounces between the front frame and inner mirror layers. It creates a depth illusion inside your case. No other fan at this price point matches this visual quality.

Forward vs. Reverse Blade Design

This is a feature most buyers overlook. Standard fans spin in one direction. Jonsbo offers both positive (forward) and reverse blade variants.

• Forward blade fans: Best for exhaust positions — rear or top of the casing
• Reverse-blade fans: Best for front intake — pulls air inward more efficiently

For a balanced custom PC build airflow setup, mixing both variants is the smarter choice. Most BD buyers do not know this option exists. PCB Store stocks both.

PWM Speed Control and ARGB Motherboard Sync

Jonsbo FR-505 supports PWM intelligent temperature control and can be synchronized with the motherboard through a 3-pin 5V optical control interface.

This means your fan speed adjusts automatically. Under low load — low RPM, quiet operation. Under gaming or rendering load — full speed, maximum cooling.

Compatible with:

• ASUS Aura Sync
• MSI Mystic Light Sync
• Gigabyte RGB Fusion 2.0
• ASRock Polychrome Sync

This matters most for builders pairing Jonsbo fans with high-quality graphics cards and performance motherboards.

How to Choose the Right Jonsbo Fan

Picking the wrong fan wastes money. Here is a simple guide for every type of BD PC builder.

120mm vs 140mm

Most PC cases in Bangladesh support 120mm fans by default. Some mid-tower and full-tower casings support 140mm slots at the front or top.

Check your casing manual before buying. The rule is simple:

• 120mm fans: Fit almost every case. More mounting options. Jonsbo FR-505 is 120mm.
• 140mm fans: Move more air at lower RPM. Better for quiet builds with large cases.

For most custom PC build setups in Bangladesh, 120mm is the safe, universal choice.

Single Fan vs 3-Pack

A single Jonsbo fan works fine as a rear exhaust upgrade. But for a complete airflow setup, three fans are the minimum.

Most mid-tower cases in Bangladesh support:

• Two or three front intake fans
• One rear exhaust fan
• One or two top exhaust fans

Buying the FR-505 3-pack gives you three matched fans. Same lighting colour. Same speed profile. No mismatch inside your casing. It also costs less per unit compared to buying singles.

For builders pairing Jonsbo fans with a cooler or graphics card, three matching fans give consistent airflow from front to back.

Intake vs Exhaust

Most BD builders make one common mistake. They install fans without thinking about airflow direction.

Follow this simple rule:

• Front and bottom of casing — intake fans, pulling cool air in
• Rear and top of casing — exhaust fans, pushing hot air out

For the Jonsbo FR-505:

• Use positive (forward) blade variants at the rear and top exhaust positions
• Use reverse blade variants at front intake positions for maximum pull efficiency

This setup keeps your PC component temperatures stable. Your PC's motherboards, air cooler, and graphics card all benefit from proper directional airflow.

Jonsbo Fan Compatibility

Jonsbo use standard 120mm mounting. They fit in virtually every PC case sold in Bangladesh.

Best pairings for Jonsbo FR-505 in BD:

• Mid-tower ATX cases with tempered glass panels
• Micro-ATX compact cases with front mesh intake
• Full-tower cases for high-end PC build setups
• Any case that supports front-mounted radiators for AIO liquid coolers

The 4-pin PWM connector works with all modern motherboards from Intel and AMD platforms. No adapter needed.
