While playing GPU intensive games I had the feeling that the laptop does not reach its full capabilities.
Even while using the recommended GPU settings by NVIDIA for the respective game, the games felt a bit sluggish.
So I ran some benchmarks using the program Furmark.
It looks like the laptop is programmed to throttle the GPU once the temperature reaches 65-67 °C.
Can this be possible?
This kinda sucks. I didn't pay for high end hardware just to have it throttled by my system's BIOS or whatever causes this.
Moreover the fans don't always seem to run at full capacity before the temperature throttling kicks in.
It also does not seem possible to control or monitor the fan speed by a third party program like MSI Afterburner.
If this is supposed to be a laptop for gamers it kind of missed the mark here.

Make sure you don't have any power saving features turned on, I know Lenovo has a bunch of Power Management software installed by default. Are you using "Power Saver" power plan in Windows by any chance?
I can max out the overclock in Afterburner and game for hours on end at 1337 MHz core, so I'm not having any throttling issues. However I did do a clean install of Windows so I have no Lenovo software running on mine.

I did a clean install of Windows 10 without any Lenovo software.
I have no power saving mode active.
I did not say the GPU is not overclockable, it is.
However, something, probably the BIOS, is actively throttling the GPU when the temperature hits 65-67°C.
Every system throttles the CPU and GPU if the temperature is getting too high to protect itself from damage. But 65 °C is way beyond conservative.
You have to try a GPU stress test to see it.
The GPU could be way faster.

I ran Valley on extreme settings for two hours @ +135 MHz sclk +300 MHz memclk and temps hovered around 67 degres as well but that is more because the cooling solution on this laptop is exceptional. I did not see any thermal throttling on either CPU or GPU in both Witcher 3 and GTA V. GPU boost elects not to maintain a 1337 MHz boost clock for super long periods of time, sometimes dipping to 1324, but that is how GPU boost works and is up to NVIDIA.
What software are you using to monitor your GPU clock speeds? I know that Riva Statistics Server's OSD does not display my GPU stats properly, for example.
Alternatively I suggest using Steam's FPS counter or something similar or compare benchmark scores to online results. The 960M is equivalent to a 750 Ti desktop, give or take. And keep in mind that NVIDIA recommended settings are not perfect.

Not sure how you are trying to establish the argument that there is no GPU throttling at 65-67°C when you are unable to get past 67°C yourself and you did not do a stress test benchmark.
No matter how good the cooling is, it is still laptop, it is hardly possible to maintain 67°C without throttling.
I used Furmark and MSI Afterburner for monitoring. There is no difference between the 2 monitors.
It doesn't matter if I overclock the GPU clock, in the end it gets throttled by the system anyway.
Here is the report.
After googling I found another guy that drew the same conclusions:

Hm, do you understand the meaning of the word 'argument', or why did you decide to get angry?
You can see the maximum clock speed of my GPU on the graph during the stress tests I did.
Moreover, first you say you don't get over 67°C degrees, just like me, then you say you got it to 80°C. If you got it to 80°C, that is interesting, please post the graph.
I do feel throttling playing games and I did a stress test benchmark.
You don't feel any throttling while playing games and you don't give 2 bleeps about benchmarks, that is cool.
Please don't hijack the thread and let somebody that does give me his feedback.

Having same problem.
Checked temperatures with MSI afterburner and when GPU reaches 67-68 degrees celsius in Evolve, fps drops from 60 to 5fps. and then backs up to 60 and then imideatly back to 5fps.
The only way to fix it is to lower resolution and put low-medium settings.
I didin't get laptop with gtx960m to enjoy low settings with low resolution..
I can enjoy low settings on my Acer with Nvidia 640m which runs at 95 celsius.
Very dissapointed with throttling.. and the worst part there is nothing we can do without cutting grills (voiding the warranty) to prevent this issue..

I personally used a new key.
I doubt it makes a difference though, I know of no Windows 10 feature that throttles the GPU except power settings, and those are fine already.
