Lattepanda Sigma fan gets extremely noisy after a few minutes
sroec 2023-09-03 15:42:27 2217 Views3 Replies After a few minutes the fan of my new lattepanda Sigma gets insanely noisy.
I've checked the temperature of the CPU and I am even sub 40 some times.
I have run out of ideas to troubleshoot it. Has someone fixed this problem

It's getting annoying. The fan functioned perfectly the first two weeks of operation and now this grinding noise appears when on operation.

I had the exact same issue (fan rattling and CPU hitting 100°C throttling). Since I couldn't find a replacement fan, I designed a 3D-printed bracket to mount a standard Noctua 92mm fan. It completely solved the overheating (drops load temps by ~40°C) and it's silent now.
