Lenovo Y40-70 - Fan/Overheating Issue

2014-12-31, 17:34 PM

I bought a Y40-70 a few weeks ago and I've noticed that it tends to get really hot (especially around the left region of the keyboard) and that the fans start going crazy when I launch games, even on low graphics settings. I took a look at computer temperatures and apparently my CPU and GPU have been logging high temperatures of around 63-75 degrees Celsius when running resource-intensive applications like video games, even after their graphics settings have been lowered considerably.

 

Though I've looked around online, I haven't found any other Y40 owners with these problems. Any help would be much appreciated!

First of all, playing a game the temperatures are going to rise (a lot in some cases)

 

I play games and CPU is at 75-78 celsius and GPU is at 78-85 celsius. these are normal for Lenovo.

 

CPU throttling occurs at 100 celsius, so you are well below that. You can check safe temperatures given by Intel.

GPU is safe until 120 I think, you can check that online as well.

 

The fans will go crazy (fast spinning) when you are playing a game unless you are getting some other weird sound like a "Rattling".

 

If you are feeling that the keyboard is getting too hot to touch, like burning almost, then immeddiately shutdown the game and the laptop. You may need to contact Lenovo since you might then have a problem with your cooling.

But as of now, you temps look fine.

To keep laptop cool -

 

1) Use it on a desk and not in bed or your lap where the cooling vents get blocked.

2) Buy a laptop cooler

3) Bring ambient temp down by using air conditioning in the room.

4) Undervolt the CPU (I do not recommend this unless your problem gets really serious)

5) Play game at optimal graphics settings, not too high.

Thank you for the quick reply! The temperatures looked concerning at first but obviously aren't a worry. Will look into laptop coolers in the future.

Hi,

I have the same problem. The laptop temperature increases as soon as resource intensive applications such as videogames are started. During the normal operation, it works just fine.The normal temperature is around 38-42Celsius but as soon as these applications are started, the temperature shoots up to 73-78Celcius within 2 minutes. Also, as mentioned in the previous query, the left part of the keyboard ( near the W-A-S-D keys) gets very hot to use.  I have begun to suspect it to be a cooling problem. I need to confirm if its normal in Lenovo laptops before contacting the Lenovo Support.
Any help is appreciated. Thank you
