20W Semiconductor Cooling

The PIVA B2 uses TEC semiconductor cooling rather than relying only on airflow.

This system actively transfers heat away from the phone, helping reduce device temperature during demanding use such as:

• Mobile Gaming
• Live Streaming
• Fast Charging
• Video Recording
• High-Performance Apps
• Long Gaming Sessions

Cooling power is specified at:

20W

This can help reduce thermal buildup and minimize performance loss caused by excessive phone temperature.

5500 RPM High-Speed Fan

The B2 uses a 7-blade high-speed cooling fan rated at:

5500 RPM

The fan works together with the semiconductor cooling plate and aluminum structure to dissipate heat away from the rear of the phone.

Fan Specifications

• Fan Speed: 5500 RPM
• Fan Blades: 7
• Noise: Low-Noise Design

Magnetic + Clamp Mounting

One of the most useful features of the B2 is its dual mounting system.

Magnetic Mounting

Magnetic-compatible phones or suitable magnetic rings can attach directly to the cooler.

Clamp Mounting

For phones without magnetic attachment, the included adjustable clamp allows the cooler to be mounted securely.

This makes the PIVA B2 suitable for a wide range of:

• iPhones
• Android Phones
• Gaming Phones
• Conventional Smartphones

RGB LED Lighting

The PIVA B2 includes built-in decorative lighting with three modes:

• Green
• Blue
• RGB Cycling

Lighting is controlled by a button on the cooler.

For catalog purposes, this can be listed as:

RGB Lighting: Yes – 3 Modes

USB-C Power

The cooler is powered through:

USB Type-C

Games World specifies a recommended power adapter of:

PD 30W or Above

Using an adequately rated power source helps the cooler reach its intended performance level.

Die-Cast Aluminum Cooling Structure

The B2 uses a die-cast aluminum heatsink designed to transfer and dissipate heat efficiently.

Aluminum is well suited to cooling applications because it combines:

• Good Thermal Conductivity
• Low Weight
• Strong Structural Durability

Compact & Lightweight Design

The B2 measures approximately:

62 × 62 × 28 mm

and weighs:

76 g

This compact design helps keep the cooler portable while still providing active semiconductor cooling.
