Hello,
My system temperature seems to be very high these days along with CPU usage and load average. Chrome, Eclipse, etc. seems to be misbehaving but I am not able to pin point the problem. Chrome usage skyrockets whenever I am browsing multimedia rich websites even like Google+ (those gifs). VLC seems also to cause a lot of these problems.
I am posting a bunch of screenshots of top. If any of you could help me figure out the problem that would be awesome.

Fans are working fine. The system concerned is Thinkpad T420i. I am running Fedora 20 KDE.

Before we jump to system software issues, I would 1. Check to be sure the cpu fan is functioning and running at full speed. On my system I always disabled speed control because I wanted to keep the cpu running cool with or without heavy loads. 2. Check to be sure the the Graphics chip cpy is also running and at full speed.
Cheers,

Like I said fan is working just fine.
fan status: enabled speed: 4493 level: 7 commands: level <level> (<level> is 0-7, auto, disengaged, full-speed) commands: enable, disable commands: watchdog <timeout> (<timeout> is 0 (off), 1-120 (seconds))
- Check to be sure the the Graphics chip cpy is also running and at full speed.
I already had Nvidia Optimus (NVS 4200) disabled long time ago. I am only using Intel HD 3000 (AFAIK).
How do I figure this out?

OK. So, since you are using a lot of multimedia, it seems to me that the Intel HD3000 is also incorporated into the CPU. Thus the very high CPU usage while doing graphical UI's and multimedia.
Only thing I can suggest is to disable the Intel graphics and re-enable NVidia. This will reduce the cpu overhead and heat generation; and just be sure the Nvidia card's fan is at full speed.
I would also be sure that you have a full complement of cabinet fans.

Well dedicated GPU aren't meant to be run 24x7. Nvidia Optimus switches to dedicated GPU under heavy graphic processes. We don't have anything like that on Linux. Just turning ON the dedicated GPU would make system temperature rise by at least 10C and power consumption also by 5-10W.

You know I am talking about a laptop. I am not sure if GPUs have fans in laptops.

I had a laptop with the 2 gpu's also. the one that was external to the CPU had it's own fan.
If you think power consumption is a big overriding issue for you then perhaps you will have to accept the consequences :) :)

I think it's more than fan or GPU load issue. There are two reasons. Firstly, GPUs are not suddenly start eating CPU one day. System has been running fine for 3 years and months on exactly same setup. Secondly, if you look into this screenshot[1] I have just booted ON the laptop and it was already running at 84C. The only thing that was started was Chrome newtab. You see load is way to high but none of the processes are taking up too much resources.

For me three years is about the time I consider doing two major service things to laptops.
1. Replace the CMOS battery. One thing you might consider doing right now is to reset all the CMOS variables to their default values. If a battery is low the values can change on their own and create strange problems that go away when the default values are reloaded – until – the machine is turned off again (and perhaps left for a time) so the battery voltage goes low and the bits slip again. Anymore I consider replacing the battery every other year.
2. Clean and/or replace the cpu/gpu fan and heat-sink assembly. The accumulation of gunk in these assemblies (often combined in a laptop) is dependent upon how much use the machine gets and where it is used. Blowing air through the assemblies may or may not be good enough. Local changes in air temperature, humidity, and altitude can make quite a difference in how fast heat is removed from the active components. As well sometimes the heat sink compounds degrade and/or mechanical issues change the heat-sink to cpu/gpu fit.
fwiw

AFAIK CMOS battery on my laptop Thinkpad T420i is on the motherboard. It is too much effort to replace the CMOS battery. I can certainly look into it. Thinkpads have really great battery life. After using this system for 3 years battery life is still quite good. I may want to save battery replacement money in future laptop though.

Advice taken.
I think Baloo the new KDE file indexer might be at fault here. Whenever I leave my system and come back I see two major processes baloo_file and baloo_file_extractor are always on top. And system temperature is around 90C. Once system temperature is that high it takes a while to get it down. Not to mention Linux tends to be very bad for multimedia stuff. Anytime you watch a youtube video there is a good chance that system might shutdown due to high temperature.

Actually, the load is not too hugh, with 80% idle it leaves 20% doing anything, that shouldn't present a heat problem. I really think you have a *cooling* problem, not getting rid of the normal heat you have.
Two ideas:
Have you opened up the case and removed the dust? I don't mean open one of the little doors and saying "oh, pretty," but open all the case bits the vendor says not to. That is my first and most likely thought.
You can measure power use by hooking up the power supply and using a Kill-o-Watt or similar meter. Each watt is 3.4 BTU/hr. NOTE: If your battery life is good, that tells you you are NOT using too much power, which tells you that you ARE keeping too much heat. I'm betting dust.
Finally (bonus 3rd idea) boot a non-KDE live DVD and watch the temperature with that. Unlikely to be related issue, but you can feel as if you now know it not something running hidden in the background and doing something you don't see.

I would not put it past the google developers to have put in code in their browser to do things you you are not expecting. I do not use it. Also, I asked friends using Apples and Chrome. Some say all is well, other report different problems.
Well just in case you get a hankering to get inside the box (yes always a risk):

I have a few things to rule out before I do that. I have to make sure Baloo, the Plasma desktop indexer and CoW is active throughout on my system including on folders that contain VM images, aren't the usual suspencts.

I would also suggest that you install the invidia proprietary driver module. On my machine:
$ lsmod | grep -i nvidia nvidia 10730592 107 drm 289961 3 nvidia i2c_core 55486 4 drm,i2c_i801,nvidia,videodev
Also: $ yum list installed | grep -i nvidia | sort akmod-nvidia.x86_64 1:331.89-2.fc20 @rpmfusion-nonfree-updates kmod-nvidia-3.15.10-200.fc20.x86_64.x86_64 kmod-nvidia-3.15.7-200.fc20.x86_64.x86_64 kmod-nvidia-3.15.8-200.fc20.x86_64.x86_64 xorg-x11-drv-nvidia-libs.x86_64 1:331.89-2.fc20 @rpmfusion-nonfree-updates xorg-x11-drv-nvidia.x86_64 1:331.89-2.fc20 @rpmfusion-nonfree-updates
On my machine, this considerably lowered the CPU generated heat.
