“Very easy to install. A bit of an essential item for some purposes. I went from a flirc full aluminium case to a plastic console imitation case and the temperature went right up. These sinks and a small fan are keeping it at a sensible level.”
“I have my Pi setup on Ubuntu Server to run home asisstant. Without doing much the temp of the board was showing as 60.9 C. I know the board can cope with these temps, but keeping components cooler is always a good thing. With these heatsinks and the purchase of a 50mm fan also from here, I was able to get the normal operating temperature down to a nice 38.9 C. Delivery and packing was also great.
