Heatsink without paste


#1

Is it ok to use the Heatsink (Official one) without the paste or Thermal Heatsink Copper Pad ?

Just seems a little permanent thats all ?

Also read about the issues getting to the emmc card afterwards all though here you can flash it via usb …

No it is not ok.
You MUST put something in between to ensure good contact.

The disadvantage is of course that you can’t reach the eMMC when the heatsink is on.

Not can’t, but it is tricky. I use a very small flathead screwdriver to lift up EMMC module and to push it down on the contacts. If careful you can do this successfully. It is a pain though and it would be nice to have easier access to the EMMC section.

Thank you Jacob.
You can reuse thermal pads. But they work a lot worse than good thermal paste. Difference can be up to 10°C.

The reason why you better not do it without a thermal pad or thermal paste is because then it’s possible that only a few small places make contact, what will make other spots a lot hotter(hotspots), and so it can burn your SoC.
So better not to use a heatsink than if you’re not using something in between. That’s less harm.

How to Clean Thermal Paste
I would take isopropyl alcohol 90% to rub off the last remnants of the thermal paste.
