Overclock GT650M ? Lenovo Ideapad Y500

[oshkosh601]

I was thinking of overclocking my Lenovo Ideapad Y500 which has two GT650M running in SLI. I was wondering if you guys could give me some help with me being a noob and all. Right now, when I run the Furry and Tessy stress test on MSI Kombuster, my max heat goes up to 76 C. What's the highest temperature a mobile GPU should go? Also, I was also considering buying a laptop cooling pad, do you guys know of any good ones ?

Thanks,
Osh.

I'm no expert, but I read somewhere that it's advised not to overclock laptops as they overheat as it is.
