“Heatsink is built really well.
The thermal pads that came with it to connect the processor to the sink crumbled when I tried to put them on. Lucky I had some thermal paste I could use instead.”
“The cooling is much better than using a Fan SHIM (at least 10 degrees less when fan is off) and silent when on. Plus no power draw compared with the fan.”
“I am sure its great thermally, but the Micro-sd memory card sticks out beyond the heavy solid case. So if you put your Pi in a bag with other stuff expect the Pi's memory card holder to be broken when you get where you are going. I say this from experience.
For those who leave their Pi on a desk and are confident it won't fall off, I recommend this case.”
“Sometimes simplicity is the answer. The RPi 4 Fan Shim was not compatible with the project I was building so ordered this heatsink case. Easy to assemble and really working well for me. Ideal if you have any slight amount of ventilation and any sort of reasonable ambient temperature.”
“Super sleek! It covers the Pi very nicely, and since it's all aluminum, it's a great sink too! I think I'm happy that I got this instead of a real case.”
