Folding isn't going to be happening on the laptop GPU, it just makes things too hot
I fold on one of my work laptop's 24/7 I just had to get a laptop cooler which cost me $10.00 bucs, now the temps stay in the mid 40C all the time.
When before I got the cooler they would run in the low to mid 60C all day.
It was the best investment I made for it.
The laptop is a Dell 6500 with an core i7M and a 400m series GPU. If it breaks it's covered under the Dell warranty we have. So I'm not really worried about it.
I also have a MacBook pro for work and it is only used for work nothing else.
Try to find you a cooler they run on a USB plug and really do work, surprised me.
