Thanks so very much, Panko for your video suggestion and reply--- I guess the reviewer was in error when he indicated that the 5591 had 2 heat pipes.
A follow-up question if I may :
Although I would really prefer 16 GB Ram so as to avoid a future upgrade a few years from now , given the video tear down shows there is only 1 heat pipe on the 5591, should I therefore limit the configuration to 8 GB Ram due to heat concerns? I would not be doing any gaming or intensive applications on the laptop, although I might be on the 5591 for ~ 6 hours/session answering medical emails as well as downloading music videos.
Also, as I know classical/jazz videos can over time take up a lot of space, I might want to consider a 1 TB ss rather than the 512 GB----but again, I have heat concerns given the limited amount of space within the 5591 chassis.
Any thoughts or comments on this I would truly appreciate.
Thanks once again for your expertise!
