As long as it is docked, or plugged in, you should not. Depending on what you are doing, it may run a couple degrees warmer than now. 

If you are not plugged in or docked and running on battery alone, it will drain faster due to the higher demand by the processor.

If you are running games, then yes it will run hotter than usual. 

My E6430 has a 3rd gen i7 in it now, and I run a R9 380 eGPU with it. And while running high demand games such as Monster Hunter top graphics settings and Need For Speed Payback, my computer does run hotter than normal, but the original fan and cooling unit are enough to keep it at a manageable level.

Thank you for the information, i greatly appreciate it. 

Will i have any performance issues due to different wattage (45W vs 55W)? Is there going to any cooling issues? and will it work with the nVidia 5200m already on board?

Refer here for compatible processors. The top one I can see would be The i7-3940XM.

but what about the power difference? 3940XM is a 55W processor. 

Hello, 

I have an E6430 with 3720QM processor,  nvidia M5200, 16GB DDR3L 1600 RAM upgrade. I use my laptop for work and it is docked 90% of the time. I'd like to get a little more performance out of it since i run multiple programs. What is the fastest CPU processor i can fit while still keeping the device safe and reliable? I have seen some user upgrade to 3840QM and have read about 3940QM get fitted. I am not interested in aggressive overclocking and prefer to keep the device safe.  Any feedback/advise/help on how i can boost the overall performance would be greatly appreciated.
