Help How do I keep my phone cool?

[Gulstab]

It's perfectly cool when I first turn it on for the day, but as the day goes on, both the temperature and chance of something stupid happening go up. Any way to keep my phone cool? I used to have problems like this on my laptop, but I'm pretty sure there's no fan or anything on my phone I can just spray compressed air into... I'm almost positive this will resolve the problem described in my other thread.
