I've had my KPA500 for a few years now. I built it from a kit. The only time I ever hear what you describe is when I've been long winded on RTTY.
I run it @ 450 Watts out no matter the mode and I never even get a fan speed increase unless I'm in a RTTY rag chew and normally never hear any thermal clicks. I don't worry about it or let it bother me.
