I’ve actually never had problems with overheating with anything.
Then again, what do you mean by problems? There are tolerances with regards to how much heat the CPI can handle, and as long as it’s not melting plastic, it should be ok.
There was no noticeable thermal throttling due to overheating.
Nor was there any artefacting or stability issues.
Comfort wise, I live in Australia. It’s always hot. I might just be used to what other people perceive as hot.
Not sure if that’s helpful or not, but I guess my answer is no; I haven’t had any over heating problems.
