    So i was messing around in some setting in the nvidea control panel and i noticed that it set the CPU to do physx..... changed to auto select and it dropped my cpu from 95c to 74c!

    I set mine to the 555M in the beginning, but never see a difference in temps. Mine stay in the 80's in Metro 2033 with PhysX on.. :/

    So that's maybe the cause of my problem as well, since I never mess around much with the nVidia Control Panel except for the program whitelist thingy. I'll have a try and update back.

    It should be set to Automatic by default. It would not hurt to offload the GPU either, might give you a few frames extra in PhysX games. And remember that not all games use PhysX, many uses Havok as well.

    Metro 2033 is a pretty heavy PhysX game though, if you have enabled the Advanced PhysX option.

    I just check again, mine was set to auto as well, but now I set it to GT555M, so should I set it back or leave it as I have set it, btw about the temp performance, I didnt notice any different though, the temp still jump to between 85C - 95C as normal (With Laptop cooler). But I do notice the in-game performance different.

    Really strange... Why wouldn't the 555M be set to do PhysX in the first place?

    I understand switching the physX to GPU may drop temp, but if it is defaulted to the CPU, didn't they choose to do that for a reason?

    Its called Hybrid SLI technology. Because the CPU has a built in Graphics Card along side the GT 555m.

    It just takes some load off of the 555m and puts it onto the Intel HD Graphics 3000 (Your CPU). Its a normal configuration among SLI setups, only the M14x is using Hybrid SLI technology (Graphics Card + CPU "Craphics Card") and not two separate graphic cards.

    That is the reason your CPU temps drop because you told it to stop doing physX, you just put more load onto your GT 555m is all.

    No it doesn't. The m14x uses Optimus, not hybrid SLI.

    Yea, the M14x doesn't use 'Hybrid-SLi', but Optimus. Switching the PhysX processor will just use 'CPU-PhysX', where the calculations are done on the CPU instead of the GPU. Of course it lightens the load on the GPU, but PhysX is usually faster on the GPU, as PhysX is CUDA-optimised. Thus, there will be cases where using CPU-PhysX will actually lower framerates.

    so is the increase in GPU temperature which I assume happens when you do this, less than the decrease in CPU temperature?
