Well, I gave up on the Passive cooling. Even with the copper blocks attached the Core CPU temperatures got into the 80'Cs playing HD video

So, I grab an old Graphic cards Fan and modified the original packaging to allow for it to sit off the bottom of the box. Took Fan power from the pins next to mini USB power port. Made a couple of air entry slot on the tabs of the original LattePanda packaging. So, that air could be dragged in via the sides slots and pushed by the fan below over the new copper block on the CPU. This setup now has the CPU's cores ticking over between 65-68'C when playing HD video and Image Backup in progress.

Here's picture. As they say, it is worth 1,000 words.

Cheers

I have looked at various videos while deciding which tiny computer to get and I really like the LattePanda except the heat issues.

There is copper heatsinks to buy in the store but they seem so tiny...
One of the videos show you can take the shield off and fit them directly on each chip... great!

I found these and they seem to have more fin area, would they work? https://www.aliexpress.com/item/Lot-20p ... e89381ecfa

Another thought I had was, the chips seem to all be in same level, can you buy one big heatsink and slap on each side? if yes, how big is the area? There seem to be a white square lined on each side of the pcb anyone got meassurements of that?

I am using an aluminum heatsink from my grandfathers old p3 build. the problem is attaching it. i used heat tape it didn't hold. had to use 2 part epoxy. it works good to attach it but i'm screwed for modding my cooling any farther.

I had the same problem with 3M double sided tape. After cleaning the surface of the chip with a alcohol towel the tape stuck.

the cpu is on the bottom of the board, so you will need to have a fan blowing on the underside

I was having heating problems when I first got the lp but I monitored it with hwmonitor and turned off the computer after about 20 minutes of use. So I got some raspberry pi heatsinks and a usb powered 80 mm adjustable fan.

I just beat final fantasy 1 on vba10, the emulator kind of sucks but, it worked for a test before the fan and heatsinks it would get up to 85 C in 20 minutes and after it stays in the 40-70 C range for hours. CPU usage is 20%-50% on all 4 cores 480 mhz to 1840 mhz. Using hwmonitor.
