High temperatures (up to 80c when idle)

Yes, I'm booting from my only hdd using chameleon (DropSSDT=No).
Output from test when using SSDT from Multibeast:

Umm... why aren't you using the SSDT generated from the ProBook Installer??


Also, now that we know you aren't quite using current methods to install, perhaps you can tell us how you installed?
And what System Definition you're using...


And... what does HwMonitor show when your computer is "idle."

I used Probook Installer, and I picked System Definition for Sandy Bridge i3/i5 (I have SB i5).
SSDT generated by Installer gave me about the same temperatures/bettery life as everything else.
That's why I'v tried different SSDTs.
My HWMonitor right now (totally idle, only Activity Monitor working) looks like this:
Ambient: 48c
CPU Die 1: 70c
CPU Die 2: 72c
CPU Heatsink: 67c

HDD: 34c

CPU Package Multiplier: x8.0/x17/x20/x27 (random jumps)
CPU Core Package: 792MHz (occasional jumps to higher frequencies)
System Fan: ~3321/3890rpm (Every time there is a spike in temperature fan goes insane for a while, then goes back to 3,3k)

Sounding more and more like a hardware problem.

Although it seems Ambient temp is relatively high. Do you live in relatively hot location without air conditioning?

Its kinda warm here (but far from 48c), so I decided to test everything during night time when its get much colder - almost no difference.
I would also blame the hardware, if not for Windows. It runs at stable 50c with fans under 3k.
I'm not sure how to get the rest of sensor data tho :/ I will try a fresh install last time.

And since I'm no hardware specialist:
Should heatsink be warmer than cpu? And will taking laptop apart and (in case its needed) applying new thermal compound void my warranty?
And is there a way to check heatsink's temp under Windows?
Also I forgot to mention that I had the "boot0: error" problem, and I fixed it using this guide (1st solution). No idea if it matters tho.

I'v bought my Probook for my college but also for iOS app development (it mostly involves coding in Xcode, with is not really taxing for cpu).
And I doubt they will take my laptop back (since there are no problems with Windows), so my only choice is to try and resolve this somehow.

Edit:
Last question: Is there a way to set maximum bus ratio? So it never goes above certain number.
