I have eMMC on board. Using the heatsink compound will get in the way of removing that eMMC. I do not want to keep cleaning and reapplying compound everytime I need removing the eMMC.
Any other effective options? Perhaps non-adhesive thermal pads for both RK3399 and 3R3 chips? What are their measurements?
Or any other easily removable options?

The gap in the middle is 1mm, which can be replaced by 3M heat-conducting adhesive paper

It’s awkward but I manage it with a super small screwdriver. Just enough to pry it off and then enough to push it down. It fiddly but I’ve got the hang of removing and reinstalling the EMMC without removing the heatsink.
It would be better if I can easily update the emmc module without removing it from the board).

Desperately need “easily update the emmc module without removing it from the board.”
It’s hard to find a 1mm heat-conductive adhesive tape.
My advice is to use emery wheel to remove a bit of this 1mm borders. That is enough to use normal thermal compound

I thought that installing via the USB OTG port would be pretty smart, but then the guide you reference says that the Rock Pi must be powered on with the eMMC module removed which is precisely what the big heat sink or the M.2 adapter don’t allow,
Can you please help me out of this confusion?
TIA

Did you under-estimate demand? >1 month until it’s available in any of the shops I use (or found). If anybody knows one that has it, preferably in Germany or at least Europe, I’d love a pointer.
Hi,
I also have the Heatsink installed. My way to install images to eMMC is to have one image on sd card.I boot from sd card and then install the image with the dd command to the eMMC card. When I then remove the sd card and boot the board boots from eMMC.

Hi Norbert,
thank you for the hint. That’ll probably be the method for me as well, although it means that I have to remove the M.2 cable in order to be able to access the µSD slot.
I had some silent hope that there might be a way leaving the M.2 cable in place which has escaped me so far.
Tnx again

Thanks for the link – a few days ago Reichelt said “2-3 weeks”.
At Innet24.de the cooler should be in stock, so I posted the link three days ago.
Rock Pi 4 zbh. Heatsink Kühler Kühlkörper
As I have just seen, in “my” Berlin shop the heat sink is in stock again.

I recently purchased first the Rock Pi 4 kit with case and then a little later the large heat sink. While I was waiting on the large heat sink, I went ahead and set everything else up. I am using my Rock Pi 4 as a Kodi device running Libreelec. It works reasonable well and is very quick. When watching Netflix (which unfortunately can only do CPU decoding), the temperature was getting quite high (around 90c). Last night I finally received the large heat sink. A couple of observations and questions:
There did not appear to be any way to just replace the old bottom of the kit case with the heat sink. I was expecting to be able to just swap the plastic bottom out, but the large heat sink did not come with additional connectors to use on the top of the Rock Pi 4. Is that expected? Is there another official case which matches the large heat sink? I don’t need the M2 extender.
Watching Netflix (which causes high CPU usage), the temp is max around 50c now, but… The heat sink does get quite warm to the touch. Will there be any options provided to attach something else onto the screw holes under the heat sink? Maybe even with a fan? For now, I’ve put my Rock Pi 4 upside-down so that the heat sink faces up.
Hello,
is there any case (not transparent) to fit that Rock Pi 4 WITH heat sink AND M.2 board???
I really need that…
I don’t get it, could you please explain in more detail why you modified the heatsink?
