back to 1 as I was a bit uncomfortable with the CPU running at 80 - 83C. 
Its only running at 75 now.
Has anyone else noticed this before? I've heard that laptops run hotter 
than desktops but surely this can't be healthy for it?

That sounds normal enough for a laptop.

Higher temperatures do indeed cause electronics to age faster than when at 
cooler temperatures. However, for your example, your laptop will become 
obsolete before the CPU fails.

There's a far higher risk that your laptop will be damaged sooner than CPU 
failure by just simply getting dropped or stolen...


Keep it on a hard flat surface so that the cooling is optimal and happy 
crunchin',

Thanks for your reply, Martin.
I had posted a message concerning this same topic not too long ago, but the 
temperature seemed to have risen since then.
I always keep my laptop on a wooden table so the underneath has the best 
ventilation possible.
My laptops less than a year old, so as long as I get another 2, maybe 3 
years out of it, I'll be happy.

You may wish to take a can of compressed air, notice I said CAN and
NOT a TANK, and spar it into the vent holes carefully just to make
sure all is open. Also if you raise the bottom off the table a bit it
will let air circulate around it a bit better.
The problem on most laptops used for Seti or Boinc or whatever program
that uses the hard drive all the time is that the hard drive fails.
Laptop hard drives do not have the same life expentency of a desktop
hard drive. People have even gone to ram drives to store the data in
order to supress writes to the hard drive, so they don't happen every
60 seconds. Laptop drives spin down and then spin up when you write to
them, this is the reason they fail. They need to spin down to save
battery power, but spinning them up and then stopping them and then
spinning them up again makes for short life spans.
Desktop drives do not spin down as soon so they are most likely still
spinning when you try and write to them, power is not an issue with a
desktop. These settings are adjustable under control panel, power
options.
