Laptop Temps

Earlier I was playing on my Everex StepNote xt5000t and all of a sudden my screen had a hazy ring around it then it began to close in towards the center. The entire comp locked up and I had to power it down the hard way.

Usually I have a laptop cooler running as it has always seemed a bit hot above the vid card. Today I didn't have a cooler. So I assumed it had over heated. So I went and got a cooler slapped it on and turned the comp on with fingers crossed. It started luckily with no problems.

So then I got curious and downloaded RivaTuner and CoreTemp to see what was what. Right now my basic core temps are mid to upper 70sC and my GPU temp is sitting at 68C. When I popped the game on and ran for about 5 minutes with my archer GPU went up to around 90C and CPU was lower 80sC with the laptop cooler on.

So my question is, do these numbers sound okay? I'm worried about the short amount of time it took for the GPU to pop up to 90C. This is my work comp so I don't usually play games on it but occasionally I have. For now I will monitor it and not play on it. Easy enough.
