"The point of the experiment is to see how the Core i5-11400 operates without a heatsink."
It doesn't. Turned an 11400 into basically an 11000.04 just to see the physical fireworks as different cores heat up with different loads. And destroying a $188 cpu in the process.
Done with an i3 2120 or q6600 that's of little to no value to anyone, that would have been more appropriate, but with limited availability, limited budgets that everyone is feeling after covid, destroying something that's very useful or needed isn't helping. That's akin to taking a 3080 and cutting it in half, just to see how many layers are in the pcb.
Sorry if that offends anyone's sensibilities, since there was a fair amount of effort put into the article as a whole, but to me it comes across as just wasting food when everyone else is being rationed.
