Far from it. I have provided informed commentary data and calculations to explain why you burnt your hands on your amp case.1. And you have nothing but speculation to offer on how any other case might differ from Ghent's case with regard to position, shape and airflow allowed. The March case appears to have even fewer vent holes than Ghent.
2. Of course it's about "fins" when they're used properly. Why do you think that the plate fin topology for heat sinks has been so widely used for so long? Clearly these "fins" would be best employed where the devices that generate heat (transistors usually) are attached on one side (the "plate") while the other side (the "fins") is exposed to outside air. I've never seen a Hypex OEM build with anything close to this and Hypex doesn't have any literature specifically referencing plate fin heatsinks that I've seen. However, I think we could agree that if someone came up with a way to bolt the ncxxxy modules to a plate fin heatsink, it would do a great deal to aid in heat dissipation above and beyond the majority of case designs currently on the market.
I haven't seen reports of the March burning peoples hands and its running at less than 40 deg C in the above data, so as I said you need to take a look at the surface area of the plate to case contact and the air flow. Why don't you contact March?
Aren't you concerned that your amp got so hot, or why as you now claim, it suddenly doesn't? something is wrong either way.
Anyway, it's late here. I'm off.
