Whats your favorite little heat sink for the Allwinner SoCs... LibreComputer's doesn't count.

I do use some real simple Aluminium-coolers ( https://www.robotistan.com/aluminyum-mini-sogutucu-seti-heat-sink )

The bigger one on the CPU and the small ones on the RAM chips

Are those self-adhesive?

Yes - they have 3M-thermal-Tape on it

I got a pack of these:  https://www.aliexpress.com/item/2031287967.html

USD 2.99.- (8 pieces/lot) back in 2017

 

I saw those on Amazon recently.

What do you think?

Same here (I think @tkaiser shared this model here and everybody copied his idea).

I think they are a bit 'overkill' and quite expensive. See the answer below.  Means, unless you want to run at maximum all the time, a cheap heat sink should do the job.

I guess this is correct and IIRC with the idea in mind helping to spread the heat (increase the surface of the SoC) for short high load. With the idea to have sane settings to throttle the SoC and keep the temperature on a healthy level software wise.

I like 'Go big or go home' stuff

Who mentioned overkill? 

I usually use those, and usually oriented properly:

#me too ... soon after the power connector died    https://forum.armbian.com/topic/6909-pi-factor-power-solution/?tab=comments#comment-52516

But some day I will amend the power-HAT from @TonyMac32  cut out the middle part in KiCAD and see if I can get it manufactured in China. So this great board, with the gorgeous heat sink gets back to live :-D

 

They are finally here. Still waiting for the thermal adhesive.

Mine also arrived last week. They are around 40% bigger than stock for Tinkerboard.

I mount this one on Hikey970

I can only recommend!
