Edit: I almost forget to mention that the site uses a lot of resources of your CPU when you are using the autoplay, this can cause problems with the heat if you are using a laptop.
man, blow the dust from laptop .. and clean junk from it.. wont heat att all (except if you use some HP notebook with crappy thermo pad instead of good paste...
im usind few years old tablet for autoplay on slots.. and have no issue with heat

I clean it like 15 days ago, as i say the use of cpu is high and thats the cause of the heat, i can see hd movies and play games with no problems at all.
