Jack,

OK, you win.

I went back to fan speed (0) NOR and with FT8 at 400+ watts, the KPA500 is only "doing" 56C max AND fan speed (2) is maxing also at 56C.  So, yes I will run the fan at (0) NOR.

Also, "rest" for NOR is 44C.

Jack,

Now that you ask.

I have been using the fan at (1) when I run FT8 to "get a head start" when I do TX.  I don't NEED to.  I like to see lower TEMP and it does.  I have been known to run 400W on FT8, too (FT8 is low signal mode not QRP) and I have been trying to get a Dallas station DE on 10m digital (in a skip zone).

Thanks for the help.

Now, my question for everyone reading - when is it that you feel the need to set the fan speed above 0?
