You can say that again, not even small off board cooling seems to be enough. The heat sink temps are a little worrying.
The old heat sinks and the new ones side by side:
Even though the new heat sinks have at least 4 times the surface area, they still get to ~55°C. I'm trying to get the temps down to ambient+15°C , but this seems to be an unattainable goal
I still have plan B though, just like the
engineer said: "and if that don't, work use more gun". I have even bigger heat sinks lined up
I'll need to get this heat problem sorted out before moving on to working on the case. The case I had originally planned for this build became too small, due to the need for increased cooling, but everything else to this point has worked on the first go with only minor problems and even though I have burned ~15 fuses in the process. I have yet to burn out anything on any of the boards.
So THANK YOU ALL
(especially runeight). Without the help and information available here (and on cavalliaudio) this build would have been impossible to do. It's so good, that even a first timer builder (like myself) can feel comfortable undertaking something as complex as a balanced EHHA.
