Chrome heating up MacBook Pro

I love Safari, I really do but as I also have Android devices, using Chrome is simply better for me due to cross platform syncing. I have however noticed one thing, Chrome makes my MacBook Pro heat up, a lot more than any other browser. I'm not doing anything intensive, just some general web browsing and maybe typing in Google Docs.

I really don't know what could be causing this. Anyone have any ideas ?

My MacBook is a MacBook Pro 13' model from mid 2010, but I've also reproduced this issue on a 2012 13' (non-retina) MacBook Pro .
