cpus can operate well at 75c so ide reccomend using 65 as your maximum
we1shcake, thank you for the reply, I do appreciate it. This is my first laptop. I've been building desktop PCs for myself and my customers since the early 1980s, and know them inside and out. Aside from my old Commodore64, this Acer is the first PC I've ever owned that I didn't build. I'm amazed at the lack of documentation available for laptop owners; mine came with a thin booklet that contained 5 pages of general information about the laptop. Nothing technical except environmental operating temperatures and non-condensing humidity operating ranges. That was it. (sigh)
Thank you again for shedding some light on my dilemma. At least now I don't have to worry about keeping my cooling platform running all the time!
Have a fine one,
