REDMAGIC VC COOLER 5 Pro Disassemble - Detailed Analysis

As the scorching summer approaches, the rise in ambient temperature affects the heat dissipation of mobile phones, causing an increase in temperature and reducing the gaming experience. Consumers typically purchase semiconductor coolers to cool down their phones. These coolers help dissipate the heat generated during phone operation, lowering the phone's temperature and ensuring smooth gameplay.

Nubia's gaming brand, RedMagic, has launched the REDMAGIC VC COOLER 5 Pro, which uses VC liquid cooling plates found in phones, combined with custom large-area TEC cooling plates, with a peak power of 36W. This cooler can also be equipped with a back clip for phones that do not support magnetic attachment. Let's take a look at the internal craftsmanship and materials of the REDMAGIC VC COOLER 5 Pror through a teardown.

The product model is PA3136, manufactured by Nubia Technology Co., Ltd., and it has CE certification.

The REDMAGIC VC COOLER 5 Pro continues the transparent design language of the RedMagic brand, allowing visibility of internal components through the top shell, enhancing its hardcore brand image.

The top surface features a CD pattern design and the RedMagic logo, with a faintly visible built-in fan.

One side features the DAO series logo.

The other side features the REDMAGIC brand.

The edges and one side of the casing are sprayed with silver metallic paint to enhance texture, with the REDMAGIC brand printed.

One end of the device has a USB-C power input port, with visible internal heat dissipation grilles.

The other end has a sliding power switch.

The bottom has a thermal pad for better cooling and increased friction, ensuring a good user experience.

The actual measured length of the RedMagic 5Pro is 68.35 mm.

Width is 58.84 mm.

Thickness is 28.71 mm.

The product's size in hand.

Net weight is about 100 g.

The REDMAGIC VC COOLER 5 Pro features RGB lighting effects, adding to its cool appearance.

It can also be connected to an app for AI temperature control and RGB lighting adjustments, increasing its playability. After unboxing and showcasing the REDMAGIC VC COOLER 5 Pro, let's proceed with the teardown to examine the internal craftsmanship and materials.

First, peel off the thermal pad on the back, which reveals the TEC cooling plate, with magnets for phone attachment on the sides, and fixing screws in the four corners inside the casing.

Light blue thermal gel fills the space between the thermal pad and the cooling plate.

Unscrew the fixing screws and remove the cooler's upper cover.

Remove the positioning frame at the bottom; the right side of the cooling plate is adhered to the VC liquid cooling plate with thermal paste.

The positioning frame has magnets for phone attachment.

Foam insulation is attached corresponding to the VC liquid cooling plate position.

The TEC cooling plate is adhered to the VC liquid cooling plate with thermal gel.

The front has a control board with a hole in the middle for fan intake.

Flip the control board; the fan and cooling plate are connected by wires.

Disconnect the fan connector.

Remove the TEC cooling plate from the VC liquid cooling plate.

Then remove the cooling fan from the VC liquid cooling plate.

The cooling fan is fixed with screws.

The TEC cooling plate has the markings PA3136-9705.

No markings on the other side.

A close-up of the control board, divided into four sections: the PD power chip at the top left, the step-down circuit for cooling plate power supply at the top right, the main control MCU at the bottom right for overall control, and the three-terminal voltage regulator chip at the bottom left for MCU power supply. RGB LED lights are on both sides for lighting effects.

The back has a power switch, fan socket, and USB-C port.

The main control chip is from YICHIP, model YC1059-F, integrating Bluetooth 3.0BR+5.0BLE+2.4G proprietary protocol. The chip supports 1.8-5.5V power supply, has a built-in single-core 32-bit core, 80KB ROM, and 8KB RAM, supports multiple interfaces and multiple GPIOs, and uses SOP16L packaging.

A complete teardown, showing all components.

The REDMAGIC VC COOLER 5 Pro is designed with magnetic attachment, supporting magnetic cooling for Apple 12-15 series phones. For phones that do not support magnetic attachment, clip-on components can be purchased, turning it into a back clip radiator, supporting both Apple and Android phones. The cooler has dazzling RGB lighting effects, supports Android phone settings via an app, and can also be used as a phone stand, offering comprehensive functionality.

The teardown reveals that the REDMAGIC VC COOLER 5 Pro features large-area semiconductor cooling plates and VC liquid cooling plates, quickly absorbing phone heat and dissipating it through the fan. It uses a Hynetek HUSB238 chip for PD power input, a YICHIP YC1059-F chip for Bluetooth connection, lighting control, and cooling control, and a NATLINEAR LN8364 half-bridge MOS chip for cooling plate driving, with a compact overall design.
