The KPA1500 uses a more aggressive fan speed table for 6M, versus the lower HF
bands. In general there is more immediate component heating on 6M for a given
power (especially in the LPF and other areas outside of the PA transistors), so
we start the fans at a lower heatsink temp.
Also, when using very high dissipation modes like FT8 and JT65 on 6M at
1000-1500 W, we strongly recommend setting the minimum fan speed to at least 1
or 2.

Is fan speed band dependent as well as temp? My fan was 0 but when I
switched to 6m it ramped up to 2 immediately. Usually anything under 45C
no fan but on 6m the fan stayed on until it got to 35C.
