Which isn't the point. The point is whether the temperature on the CPU silicon is the problem or if the heatsink temperature is the problem. Of course they influence each other, but using one or the other may give different results (which you can't predict and you have to test).

Perhaps you can underclock the graphics card. The nvidia card should be a lot faster even if you underclock it to 1/3 Mhz rate. FA really doesnt need that much GPU power. You could also use a cooling pad like this one:

Ther are multiple versions of the 555m, performance varies a fair bit. 35 watts is not massive and it is not IN the cpu.
It's worth a try.

With this laptop there is only one fan and one heatsink; using the nVidia GPU means the entire heatsink will be hotter. Either way the cooling is probably lousy. If the little heat of the Intel GPU would affect it more than the colossal (in comparison) heat of the nVidia GPU it would be just another proof of lousy cooling.

No, the nVidia GPU adds more heat than the Intel GPU.

You can't say that unless you know the way this laptop cools itself. It's quite a different since the integrated graphics is on the same silicon as the CPU (means heat from Integrated Graphics affects CPU directly) and the NVIDIA GPU could be using another air intake (usually not the case). If it's before the CPU (in the intake/outtake stream) it might affect it more than if it's after the CPU. Nothing to say without knowing the exact cooling system on this laptop (including numbers), but it's not as easy as you say it.

No, the nVidia GPU adds more heat than the Intel GPU. The Intel GPU has another drawback though; it eats from the system RAM memory bandwith.

Be careful with 3rd party temp / fan regulation programs; even TPFancontrol conflicts with the current Lenovo Power Manager; seemingly random putting the system to sleep.

And we still need to get a confirmation that all of this is while plugged in, not on battery. Lenovo has a tendency to limit (by means of BIOS) the max CPU clock while on battery.

Yeah, based on the pictures - There is definitely a power saving feature at work for you somewhere. I also, agree and give backing to everything E8400-CV has just said.

Can you go into Bios, and disable Intel Speedstep? What if any for options does your bios have?
Also, go download RealTemp and run it if you dont mind. From there we actually know what kind of temperatures you're seeing. Then we can find if the cause is Heat related. A cpu will decrease voltage/clockspeed when it gets too warm.

What BIOS are you running? Do you also, besides the Lenovo Power Manager, have the Lenovo Power Management Driver? They are two separate downloads on the driver matrix page. What BIOS do you have? Did you check the changelog of newer versions to see if there is anything changed in regard to CPU clock?

Let's assume it can (highly doubt it, but then I'm not running FA at such a low pixel count). It will however eat significantly from your memory bandwidth. The Intel GPU eats memory bandwidth from the normal system RAM; meaning the CPU has to make do with less. That's why you will see an increase in FA performance when using the nVidia card, because that one doesn't eat from the normal RAM; it has it's own.

Btw; do you have any question marks in the Device manager? Are you running 1x8GB DIMM or 2x4GB? The latter will be faster; it enables dual channel. Especially if you insist on using the Intel GPU.

Nominal clockfrequency for a i72670 is 2.2 GHz without boost. Turboboost is 6/6/8/9, meaning max 2.8 GHz at four cores, max 3.1 GHz on 1 core.

Yours is running at 2.0; meaning it's running throttled.

If you have the Lenovo Power manager: check the advanced settings there. There is a lot to set, and you can pick and modify from a lot of powerplans. If you don't have the Lenovo Power Manager; see if it's applicable to your system and if so; install it. If you don't want to install it; check the Windows power options; deep in there are also options to set 'maximum CPU state'.

Since you mention overheating for avoiding using the nVidia card... it's probably an overall lousy system with bad cooling, like most laptops.

Please make sure the FA executable triggers the nVidia card. There is an option in the nVidia drivers to configure what stuff uses what GPU.

The best route of course remains buying a desktop: it's better for the lifespan of your laptop; it's better to play games on and it's cheaper for the same performance.

at all times the temprature is roughly the same and if i detect any increase (easy to do since lenovo fins are pretty senstive) i can turn the fan under the laptop on.

also considering the OS its windows 7 x64 bit.
and those images taken with nvidia gt 555m OFF. i mainly use the intel HD GC to avoid over heating.
anyway the images are here first is the DP pic.

then the CPU idle pic.
