I don't think I agree, but if you have some sources you can share I'll gladly change my opinion.

My assumption is that if a cpu isn't thermal throttling, you aren't going to get much or any additional performance out of it. You can get lower Temps for sure, but I don't think that equates to more performance.

Edit: assuming you aren't able over clock any higher due to stability, which would be the case for the majority of consumers.

If you get lower temps, you can get more performance. That's overclocking 101.
