It sounds like that to me, but something in .32-rc causes it to not throttle early enough. .31 goes very close to the max all the time, but something thottles it to not actually go over it.

No idea, really. The fan rarely every starts when using .31, but comes in a lot using .32-rc

Yes, perfectly. Have been running it for a couple of days now again after I had all these reproducible .32-rc shutdowns when testiong it.

Haven't tried that yet, will do if it helps you.

Well, I do hear the fan on .32-rc (not on .31 usually).
