K3 PA Temp Max (was Re: K3 Noisy fans?)

[Jeff Wandling W7BRS via K3List]

I'm glad someone brought this up.

My question is:  What is the safe temp range for the KPA3?  I can get the PA
temp up to 56C at full power (100W).  Fans are of course on full-bore at this
point and I still can barely hear them.

At what PA Temp do I need to be concerned?

I'm using the K3/100 with the KAT3

We're good to at least 85C (which is still below the max temp for the
transistors) where the firmware will automatically drop the 100W amp out
of line to protect it.

You can run all day below that level.
