Geekworm Raspberry Pi Zero 2 W Heatsink C296, 10mm Aluminumn Alloy Heatsink Radiator Compatible with Raspberry Pi Zero 2W / Pi Zero W/Pi Zero

Great Raspberry Pi Zero Case / Heat Sink. Does the job without additional heat sinks. Good value.

I ran a 30 second, 8 thread, stress test on each unit in the same case design. 17c cooler with the heatsink. The case has air openings but no fans. Overall 10C cooling would be expected. But this one out performs expectations.

I have my Pi attached to a WaveShare PoE hat, which is great because I can run my Pi with only a single cable being connected. However, the PoE hat produces a decent amount of heat. This heatsink became an essential add-on to ensure my Pi stays cool and functional. I opted to use the copper plate and thermal paste, and I've had a SUBSTANTIAL drop in temps (PiHole reports ~42c now instead of ~60+). Well worth it for the price and options that come with this kit.

I used this on my Radxa Zero 3W. I had to grind off a bit of the aluminum on the USB C connector to fit as well as add a bit more padding as it is a bit too high for Radxa Zero 3W. Overall, it brings my Radxa Zero 3W down by 5 degree on idle.

Very nice heat sink. It also does not cover the wifi antenna so now attenuation of the wifi signal. However, there is nothing for the bottom of the pie. It would be nice if it would have sandwiched it between plates, that way the bottom is protected.

Excellent overall. May interfere with hats—an extender would help. Unless you’re overclocking or dealing with heat, the heatsink isn’t strictly necessary, but it does provide a clean look by covering the top of the board.

This one will do it's job, but it's pretty bare bones. I chose this one over the other options because of the taller hestsink fins, but now that it's assembled, I really wish I'd gone for one with a bottom plate. The board clears the desk by 1-2mm on the included nuts, but it's definitely unprotected. It'll work for now, but I'll likely replace it sooner than later.

Works with a clone called Banana Pi Zero 2. I run it 24/7 to use something called OctoPrint to control my 3d printer. It has two different thermal pads to help connect chips of two different heights to the heatsink.
