Sony :: Vaio FZ Temperatures

My friends model Sony Vaio FZ (VGN-FZ17G) which is the exact same model as mine currently ran into a hardware problem with the GPU (NVIDIA 8400M GT) which is causing his computer to crash and has since turned the GPU off and is running on board graphics. Apparently its going to cost him about 1k (AUD) as its out of warranty to fix as they need to also replace the Motherboard.

He does play quite a few games on it unlike me which I use this computer mainly for design work.

This got me thinking since I've always told him my notebook always runs reasonably hot and thus the fan goes up and down loudly which he never really experienced nor ever complained about haha.

I've just installed the speedfan application

I've had this computer up running the entire day doing basic work like internet browsing/photo viewing and Photoshop usage. Currently its idling at

GPU 75C
CORE1 70
CORE2 70

are these temperatures normal on the vaio FZ notebook models?
what are yours?

these will only go higher when playing a video game such as Left 4 Dead or video rendering with Premiere Pro if these are just basic work temps and that's a bit worrying for me.
