I've tried switching to Mint (it was Mint 12) about 6 months ago, but failed to do it due to enormous overheating which made it virtually impossible to run any applications more complex than Gedit.

Time had passed, and now I'm back again with Mint 14, but feeling way more determined.

What I face are the following issues:

1) Great overheating (and by great I mean that just by doing nothing my CPU temp is floating around 70-75 C, which I find a lot)

2) Running multiple applications (let's say Chrome, Skype and Pidgin) results in critical overheating and immediate shutdown of the system

3) Due to the stuff listed above, my battery drains in about 10-15 minutes, pretty much turning my laptop into a crippled desktop machine

I've got a HP-dv6 laptop (i7, 6gb RAM, dual graphics)

what i've tried to do already:

1) I've edited my grub file to add some "splash" arguments there

2) Installed jupiter and powertop

3) Tried to upgrade to newer kernels (up to 3.8), btw running anything newer than 3.5 results in both resolution and wi-fi detection fail

4) Read lots of forum threads devoted to the topic

So, my question is simple:

What else might I do to become finally able to use Mint as my default OS without the risk of being burned alive by the CPU heat?
