okay, I just ordered what magicse suggested ^^^ . It would be nice if you could post the metrics if possible or may be I will once I receive the order in 15 - 20 days ...... also, hopefully I don't need to cut the fan connector to fit into the GPIO ....... ....

Temporary heat sink using 4 pennies . Pennies before 1996 had 95+ % copper in them

The big one its not a good idea,soc and ram is not on same high

The height of the H3 is 1.18mm while the RAM (k4b4g1646q-hyk0) is 1.10mm +- 10% (depending on the solder balls, I suppose). I'm guessing if the thermal interface material were a tiny bit thicker, the 25x35x10mm heatsink would be ideal. a 35x35mm heatsink would be too close to the GPIO headers so I believe the 25x35x10mm heatsink as mentioned by magicse is the best option we have.

If you have time to modify heatsinks available out there, you can fully cover the h3 and the ram on the Orange Pi PC by cutting a larger heatsink to 28mm (distance from top of one RAM chip to the bottom of the other) x 35mm (distance from the far sides of the RAM chips to the lower left corner of the H3.)

Hi,

For cooling down orange pi one I use 26x20x40mm heatsink + additional  2mm alu spacers, connected with thermal epoxy glue...



temp. for now are below 40C.. (with openelec) I will check performance with some pi calculations..

My Zero running Armbian with some CPU intensive tasks (rethinkdb 2.3.6 compilation) commits suicide regularly.
Tonight, I'm trying to install asciinema, and it's heating, but not enough to die.

Copy the Code

What kind of heatsink could I install? I am using the OrangePi black box with the extension card, which doesn't help with the heat.
Thanks.
