“Bulky block, but comfortable fit on the board. Fits under a fan if you need belt and braces. Keeps the temp to well below 60C (and 30ish with a fan). Thought it might conflict with the GPIO pins, but there is enough room (just). Take care fitting it.”
“A useful addition. A large heatsink to help cool down your Pi during heavy processing operations. The size of two large first class stamps, it can be a tight fit between the display, GPIO and camera ribbon cables. Thermal backing tape included on the base of the heatsink.”
“The use of a single heatsink to cool the circuitry of the Pi is a good idea. The even dissipation of heat provides an effective and efficient method of the thermal control of your little computer. I expect that there will be situations where the heatsink might not fit perfectly into some Pi cases, especially when using a fan but this is not really an issue with the wide range of cases that are available. I recommend this product.”
“Good contact with the processor and a large surface area to dissipate heat. Using it under a fan shim with great results, although the thermal pad doesn't seem to make good contact with the other board components so I'm worried it acts as a heat trap for them more than cooling them.”
