Mike,
I do a lot of RTTY and other sound card modes with my K3-KPA500
pair. I have the amp go to 70c sometimes, that is when the HIGHEST
speed fan kicks in, NOT 65c. Not a problem, many RTTY contests and
still works fine! The room ambient temp has a lot to do with the temp
of the KPA500, in the summer I hit the 70c a lot more often than I do in
the winter, when my shack is 63-65F.

I was running the RTTY contest this weekend and expected to see higher
than normal temps but on 20m and maybe 15 the amp was running 65c and
up where the highest speed fan would come on. Generally in RTTY I
would up the normal fan a couple of notches and it would be fine. I
was not pushing it for full output either as I was not serious in the
test.
Nothing much has really changed here so I am a bit confused what might
be going on here.
