I got this, It may not fully cover the cpu, but I think it will be better than not having a heat sin ...

I believe the bigger one is the exact size of the H3. And the price is very nice I got a 5 pieces set from eBay with heatsinks that were 14x14x10, but I am hundreds of miles away from home again and I do not have the link here. The whole set cost between $1 and $2. I got a couple other sets too, but they were all still on the mail when I left, so I can't comment on any. Some people say the only true solution is to add a cooler too, and perhaps they are right, but the heatsink alone should at least lessen the problem. That is what I am counting on anyway Please leave your impressions after adding the heatsink.

Came back home today and found one of the heatsink sets and the thermal adhesives in the mail. Cleaned the surfaces, attached the heatsink, but still getting CPU3 killed during boot

/sys/class/thermal/thermal_zone0/temp and /sys/class/thermal/thermal_zone1/temp do seem to be 3 or 4°C cooler though, but apparently not enough.

Here is my temporary solution lol. Just a washer and some themral paste under it with a zip tie.  And a small USB fan on the side. Its keeping things below 55*C. My better heat sinks and a fan for the rPi (compatible with orange pi) are in themail.

I have set the CPU cores to the 1.53ghz max (The image I was using was limiting the freq to 1.2ghz untill I swapped out the Uimage file I was using, to get rid of Budget_cooling (others on these forums have mentioned how to do that.)
