Accessory for Raspberry Pi 4 8GB

This accessory kit is designed for the Raspberry Pi 4 Model B with 8 GB of RAM. It includes a copper heat sink to help manage thermals during sustained workloads. The kit targets hobbyists, educators and developers who want a ready-to-fit cooling addition for their existing board.

Suits Pi 4 owners needing passive cooling

Makers running long compiles, media servers or desktop-style workloads benefit from the extra thermal headroom. Builders using a case with no fan mounting points or those who prefer silent operation will find the copper sink a simple upgrade. Users who already have active cooling or who plan to install the board in a well-ventilated enclosure may not need the extra hardware.

Copper heat sink improves thermal performance

The included copper heat sink draws heat away from the processor more efficiently than the bare board. This can reduce throttling during extended high-load tasks such as video transcoding or compilation. No software, mounting hardware or thermal pads are mentioned in the supplied data, so buyers should verify what additional items are required for installation.

Questions about this item

What Raspberry Pi model is this copper heat sink designed to fit?

The accessory is compatible with the Raspberry Pi 4 Model B 8GB version and attaches directly to its processor for cooling.

Will the USB 3.0 ports on the Pi 4 work with my existing USB 2.0 peripherals?

Yes, the board provides two USB 3.0 and two USB 2.0 ports; USB 2.0 devices will operate normally when plugged into the faster ports.

How can I confirm the dual 4K display output is active after installing the heat sink?

Connect monitors to both micro HDMI ports; if each screen shows a 60fps desktop, the dual 4K capability is functioning correctly.
