I suppose it's netflix. I watched an episode of Mad Men last night and then this morning I realized that one of the bottom pegs had begun to melt, only one though, surprisingly. but I think it's the one that is directly under the CPU, which tends to get the hottest out of all the computer.
This had begun to happen a little over a week ago while playing a game of Plants vs Zombies but was pretty minimal. Pretty odd actually. I'm heading to an Apple Store tomorrow to talk to someone there.

I just installed SMCfancontrol and set my minimum fan speed to 4000rpm. My operating temperature currently is about 50°C
Will having the minimum RPM set higher, lower battery life?

Yet another update - just tested running netflix on my macbook air with the smc fan control open so i could monitor temperature. Within a minute the temperature had gone from 46°C to 67°C and felt noticeably hotter. Now just imagine that for 40 minutes...it would just get hotter...and hotter...and hotter. Looks like ill have to go back to watching netflix on my iPhone.
