“Testing a raspberry cluster with HPL Linpack stresstest, clearly gives the best CPU cooling with this heatsink and a minifan. The thermal conductivity of the sticker seems OK, you can always reglue it with thermal paste, but nothing beats the thermal conductivity of copper. Very happy with these.”
“Easy to apply. People say you don't need these for Pi Zero W's at all, and that's probably true, but for so little money it seemed like a good idea just to rule the heat-sink out of any potential issues I might have later on.
Unfortunately, I didn't take before and after temperature readings, but my Pi Zero W runs at about 40ish and under no matter what I ask it to do.
And it looks cool. :)”
