(was more power than I needed too) Recent checks prior to my last failure in June still showed 70-72A peak. That should be plenty of margin for an ESC rated for 90A. Short of installing refrigerated air, I feel like I did what I could to keep the C54 and Mezon 90Lite cool.
Yep, cooling looks reasonable to me. Surprised you're seeing such high currents from the CRS/C54. Are you using the recommended props?
The maximum I've seen on my CRS is 73A peak or maximum and I don't use any limiting at all. The average current (throughout a flight) would be much less than this figure.
It would be interesting to know what your ESC temps are. I've not measured mine but it's limited to 100C which I believe is the default.
