There are a few videos on YouTube showing CPUs running without a heatsink. I haven't watched them to see how long they can run for, or if any BIOS changes were needed (I noticed the first mentions a lower voltage needs to be set to boot into Windows), but it seems possible at least. There are also comments that claim to have done this (the oldest I saw was a Q8200, and someone said a 3000G could be run indefinitely without a heatsink). https://www.youtube.com/watch?v=tU9yjwMlbRI https://www.youtube.com/watch?v=tU9yjwMlbRI (Ryzen 3000) https://www.youtube.com/watch?v=ycIF1NDkW6M https://www.youtube.com/watch?v=ycIF1NDkW6M (Pentium G5400)
