“It’s very good. I used a aluminum bandsaw to cut it into smaller pieces to fit better on my pie five and cover specific components but it works very well and the thermal pads on it are good.”
“Bought this in conjunction with the Coupé Ninja case, and while I'm happy with how the case looks and how the heatsink performs, I have to take one star off for the video instructions: I slotted the heatsink in as instructed, but once it was stuck down I realised it abupted the GPIO pins, rather than the case (see picture). I'm not using the GPIO pins so it's not a big deal, but since the heatsink is so sticky I could imagine this could case me or someone else grief in the future.”
“I have this on a RPi 4 running Homeassistant, wit a standard case. It's generally at around 42C compared with the 50+ that it was previously at with a smaller sink.”
