“Simple Headsink with Glue on the base. Easy to install, full in Function - it cools down the Processor. If you have the Pi idle nearly all the time the heatsink is not necessary, but if you have intensive processes to run it's gold.”
“I already had another heatsink before mounting a HAT (HiFi audio DAC) but it was too big so had to come off. I was concerned adding the HAT would in turn generate more heat inside the case and raises the temperature of the hot parts of the pi even further. These low profile 6mm heatsinks are difficult to find from any other supplier but they do the job nicely, these ones actually look pretty good as well as being relatively inexpensive.”
“Gets hot! More due to the project than a fault with the heat sink. Used with zero and camera module for a bird cam, which has the camera running continuously.”
