[TenTec] Orion II cabinet temp?

[cx7tt at 4email.net]

Hello,
I have my O II on the desk with a cabinet about 3 inches above it and 
open in the back. The shack temp stays around 70 to 80 degs. I have 
noticed that the front top gets very warm....my fingers can reach back 
about 3 inches or so. This is regardless of my operating. Frequently I 
turn the rig on at sunrise and may run it all day long with maybe only a 
couple of QSOs. I am guessing that the temp is in the low 100s. Is this 
normal?
The majority of the heat is from the left edge of the display and goes 
to the right until left edge of the Band selection buttons. I also run 
the rig with 65 w out as this is more than enough to drive a homebrew 
amp. The heat sink fins are very cool to the touch as I write this. The 
display is set for Backlight-medium and LCD Display-Color 4
I do not have the outboard fan option installed as I rarely do RTTY.  
Would this make a diff?
