[Elecraft] KX2 in FT8 mode - heat?

[Barry N1EU]

I'd appreciate hearing from others who are using their KX2 in FT8 mode in
terms of your experience with power output and acceptable PA heat level.
The reason I ask is that I'm running 5W on 40M with the rear foot down (rig
tilted up) and I'm seeing the PA temp reach 60deg C in ordinary qso'ing
(i.e., xmit for 12 sec out of each 30 sec period) with low SWR.  How much
power are you running?  Are you using extra cooling of any type?

Thanks & 73,
