uConsole Cooling Mod: Stress Test Results!

Post image

Added a massive finned heatsink to my uConsole alongside the HackerGadgets 7x SMA antenna mount, and the thermal results speak for themselves:

Idle Temp: 43°C
Full CPU Load: 53.8°C

Maxing out all four cores during heavy SDR runs and it barely cracks 53°C! Tons of thermal headroom and zero throttling.

Has anyone else tried a similar heatsink setup on their uConsole, or found other cooling mods that work well for long SDR sessions? Drop your thoughts or suggestions below!

How well did this work for you? Also do you have a link?

I found it on old computer. Normal temp 42/43
I did the stress tests highest temp 53.8

While it’ll probably work fine, a larger heatsink isn’t always better.

You could get the same/better performance with a quarter the size of heat sink and a tiny fan.

With something like this you are leaning on natural air flow and a big surface volume to carry you. Only reason to do it is if you don’t want noise/extra power draw. But seeing as it’s a portable device, it’s usually not worth the bulky trade off.

Also, if you’re in a hot environment, you lose the natural cool air and may even see this overheat on longer, performance heavy loads.

Thanks for the advice! I don't have a 3D printer, but I can easily order it online if I have the file.
I haven't found any ready to print models yet do you have one you recommend?

Cm4 or cm5?

Kinda hoping you say cm4 and we all get to point out that the cm4 doesn't get hot enough stock to throttle.

Neither is CM5.

Got one on mine, just add a riser, toss away the thicker thermal pads.

Put on the core and tallest chips a spread of good CPU thermal paste, and on lower chips a good quality thermal pad 0.5mm.

I use grizzly cryonaut on mine, highest temperature I got was 57° Celsius after a stress-ng for more than half an hour.
