For compute intensive work, stick with the desktops for now.
There is an issue with those softwares that measure temperatures and it's this. How did you verify it's accurate? I use a laser spot thermometer. What did you use?
I got a Sony Vaio Sz650N model, it running on a Core 2 duo processor, window vista business, 2.2Ghz, 2G of rams, and a Nvidia Geforce 8400GS. I also got one of the software to monitor my CPU Temp, it said that my CPU Temp is 70C, both of my Core is 71C. Is it bad for my laptop because it has been running like that for 2 months now. I am really worried about my laptop will over heat and over clock. So if anyone know the answer, please reply to me ASAP. Have a nice day.
