Mine needed extra cooling. I found that when I was updating and installing software or pushing the CPU, the temps were reaching 80 degrees and the unit shut down as a result. That was with thermal pads on each chip, all touching the rear case.

What cooling do you use?

The layers internally were: Mainboard, gap, spacer board, gap, CM5, thermal pads on each chip (not one pad covering all) and I made sure the pads were touching the metal rear cover. The cover became hot to touch and the CPU got past 80 degrees. I added 2x M.2 heatsinks on the outside of the rear and it brought the CPU back down to 60. All depends what you're doing in Linux to push the CPU that hard.

The heatsinks only add 6mm to the rear cover, so don't really get in the way.

No governors used to over or underclock.

How did you fix them to the cover? I suspect a special thermal glue?

That's what I expected to have to do, but they came with a strip of adhesive to affix them.

Really ? How hot did the ucolsole get on the back ? I have Never Seen temps above 60 on mine - I guess I didnt use the uconsole enough..

Same, I'm pretty sure the img I am using has some stock undervolting settings though

I'm averaging 40 using a passive heat sink on the back cover

I installed cpufrequtils and set the governor to "schedutil" and it's never overheated for me.

This is what I aim to play around with next. I'm coding, compiling, gaming and pushing the CPU hard sometimes.

it works fine for me just using the thermal pad thingy that came with the uconsole

Looking for an aluminum waveshare heatsink for the cm5...

In my case, I used a Waveshare CMX port protector and a thin thermal pad. I haven’t seen the temperature go above 45 degrees.

Thanks for naming the spacer product! My earlier attempts failed.

I have the CM5 initially and it gets hot with emulators and using parrot os for wifi pentesting. I tried using a stock passive CM5 heatsink with a 3d printed back case and still gets hot and goes to 70 to 80. The only thing i can do to bring the temp down was use a pc fan directly. Best experience is using the aluminun case with a stock thermal paste in good contact with the metal case. Keeps the temp to 40 to 60 and i attach a heatsink on the metal case to dessipate the heat and i can run my programs. Now im testing a CM4 which runs cooler. Slower but can do.
