Lenovo Yoga 720 15.6" Overheating

Hello,

 

I received my laptop 3 days ago from USA but i am living in another country(Turkey). Anyway, everything was fine since i played a video game. (Battlefield I) 

 

Laptop getting so hot even I can't touch back of the fan exit. So is there a solution to fix it like applying repasting thermal or something like that? 

 

Another question is what is the average of heating for normal? Is there any suggestions for testing my heat temperature?

 

I think I can't replace it because probably Lenovo services does not look at my computer model.

 

Thank you so much.

Hi there, Cem_kil                    -

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

Temperatures for this type of laptop is normal to be from 50 to 90 while in gaming it is normal that it is at 70-90 which is really normal and throttling thing could be due to your laptop has dropped from charger to battery so make sure you got a 170W charger and not a 120W one since if it's a 120W it will kill 2nd gpu once it begins to run on battery so thats why make sure charger is an 170W not 120W

 

If you get high temperatures, you can try to decrease the heat by:

  1. Using a good quality cooling pad that runs on high RPM or a better cooling in your room.
  2. Replacing the stock Thermal Interface Material with a good quality TIM likeNoctua NT-H1Tuniq TX-4, or Artic Silver 5.

Update us how it goes.

Hello,

 

Thanks for your quick support. I tried to learn my charger watt but I couldn't.

 

Would you like to tell me what is it on this photo?

The Yoga 720 15" comes with and requires the 135W adapter, which is what you have. I believe Shashi is thinking of a different laptop since he mentions 2 GPU's and 170W adapter.

 

Repasting helps quite a bit. It's not difficult to do, either. Check out my post about it here: https://forums.lenovo.com/t5/Lenovo-Yoga-Series-Notebooks/Yoga-720-15-quot-Re-pasting-the-CPU-amp-GP...

 

I've been told that temps over 90 celcius are hard on electronics, but the CPU in our Yoga 720 runs up to 100 degrees before it throttles. After repasting, I can't make it hit over 90 no matter how hard I try, with turbo-boost on, which is disabled from the factory for some, limiting you to 2.8Ghz until you re-enable it manually. In the Skydive benchmark, I think it hit 90 on one core. It was hammering against the 100*C limit in that benchmark before. Anyway, that's all in my linked post so I'll stop blathering on about it.

 

Let us know if you repaste yours.

Re: Lenovo Yoga 720 15.6" Overheating

I got Yoga 720 15" 4k a week ago. It is running great, much cooler than my Yoga 2 Pro! I had to use a cooling pad with fans to be comfortable with the Yoga 2 Pro on my lap, but have not needed any cooling pad with the 720, whether on my lap or on sheets and quilt over my lap. I am running a lot of apps and web browser tabs at the same time, no problem. I don't even hear internal fan running unless I turn it upside down and put my ear on it.

 

So I wonder if yours is just not right somehow?

OK now run PUB-G or GTA 5 while viewing your CPU & GPU temps, then tell me how cool it's running. Smiley Wink

Re: Lenovo Yoga 720 15.6" Overheating

Hello,

 

I use MSI Afterburner and get this results,

While playing game without charging (Battleground I) heat is 61 celsus

Playing game with coolpad (which is not qualitified coolpad so cheapest one) heat is 61 celsus

Playing game while charging maximum heat was 83 celsus.

 

I think not so bad but it would be more cooler. I will buy a good coolpad next days and i will write.

 

Thank you.

Also just discovered heating while drawing on photoshop at bottom bezel. Does anyone have it? It is on the photo where is there. I fear this heating will spread of screen and the screen gonna whiter due to heating. Is it possible?

Well the hot air does vent out the back and upward right into the bottom of the display when in normal laptop pose. The CPU & GPU also make the area above (behind?) the F1-F12 keys get hot and that probably radiates to the screen as well. I would repaste with Kryonaut or similar and get a cooling pad use your cooling pad. 1 gram of Kyronaut is more than enough for $12. Run ThrottleStop and make sure turbo boost is disabled. You could undervolt as well, but I saw no difference in temps when I did it.

Re: Lenovo Yoga 720 15.6" Overheating

Hello,

 

I have a question. My Lenovo Yoga 720 15.6" doesn't overheat, although I've noticed something rather odd. When I play Fifa 17 with the charger plugged in, the fans are very loud and the laptop gets pretty hot. When I play Fifa 17 on battery only (charger not plugged in) the fans are quite silent and the laptop doesn't get hot at all. Why is that? For all I know, I would expect the exact opposite...

Thanks in advance!

Kind regards,
Tijs
