I am also having this problem. The heat starts from left side of my keyboard and then disperses toward the left palm rest and the touchpad.
I have updated all the drivers to the lastest. But the problem is still... Anybody here has idea? Really appreciate it!

I have this problem too with Windows 7 preinstalled and integrated Intel HD Graphics.
Left side of keyboard is very hot even if CPU is in idle state.
I think there is issue in fan control, because my fan starts only when CPU temperature is higher than 50-55 °C

I have the same issue , but it is not related to VGA NVIDIA driver, it is related to your Hard Disk drive,
I have the same issue , I disconnected my SSD drive and i reconnect it to USB external adapter,
then the hot area become normal temperature , even my ssd on USB is in good temperature !!,
maybe it's related to local hard disk controller.

I upgraded to M.2 SSD ADATA SP600NS 256GB as my boot drive and Seagate Momentus SpinPoint M9T 2000GB as my data storage. Seagate is most of the time powered off, so heat is reduced to minimum.
After a year of pain, I am happy with my T440p(roblems) now!

I too am having this issue. I recently acquired a T440p and just finished upgrading RAM+SSD+LCD with clean install of Win10 Pro. I put a lot of hours into it, setting everything up the way I need it. I use my laptop everyday. It's on for like 10 hours a day, sometimes more.
Mine is with the i5-4200M, 35W TDP and no Nvidia GPU.
I too am finding the keyboard on the left side is very hot. I measured surface temps with infrared thermometer. The leftside of the keyboard is much hotter than the right side. The S key reaches 38C while the Enter key is 29C. This when CPU is idle at around 53C core temp.
I also checked if I have the newer part # for heatsink & fan and I do (00HM902 is what I have). I also carefully reapplied cpu thermal grease. Under 100% load CPU only goes between 70-80C (I forget exactly).
My Crucial SSD shows 48C. When I open the bottom cover and scan surface temps the temperature radiates outward from the CPU. Even the SSD beside it is hotter on the side towards the CPU vs. the other side.
CPU temp is fine. What isn't fine is surface temperatures, especially on the keyboard and palmrest on the left side. The fan is also rather loud and comes on often even with low CPU loads.
I'm wondering, are all T440p like this? What about T450 and T460? Is there a better heatsink & fan I don't know about?
I'm a long time thinkpad user but gotta say Lenovo has taken the thinkpad into the dumpster. I chose the T440p on purpose because the 15" models have the silly numeric keypad. The T440p is enough performance for my needs, but this heat issue is bad. It makes it very uncomfortable for all day computing. I never expected this from a thinkpad. I've had quite a few over the years, never had a heat issue like this.

Ya, all T440p are the same! Is interesting that L440 doesnt have this problem. It is cheaper model, but provides better cooling system and isnt affected by CPU whine.

Thanks for the confirmation. Looks like I either have to learn to live with the noise and heat or search for something different.
Lenovo, please bring the Thinkpad back to the greatness it once was!!

I'm currently suffering with this heat problem. It starts over my keyboard and after I check underneath my laptop, I almost can feel that I can fry an egg due to the temperature. Should I buy a "chinese"-cooler-portable to put on the side of the laptop?
I'm kinda sad with this topic. :/

Hi Alexsleep, please make sure you have an "CPU Deeper Sleep" option Enabled in your power management profile. There is not much more options you can do to reduce the heat. You can change thermal compound or RMA the laptop.
