Re: lenovo yoga 710 cpu temperature concerns

What's your ambient temp when burning in? Were you on battery or plugged in? How long did you run Prime95 and FurMark?

I do think that your 83º is a little on the high side but if you ran it for 15 minutes in a hot room that may be expected.

Re: lenovo yoga 710 cpu temperature concerns

Hi,

room temperature here is at 22 degrees  C.  Both tests were run for 30 minutes to see if the temps would creep up above the ones I mentioned.

 

Yes. It does seem a little on the high side. Haven't macde any corrections to the build, nor have I installed non standard software. 

 

The fans are loud, but functional. Is this cause for returning the laptop on warranty?

Oh, you're running it for 30 minutes? That may be normal then. I know I should be able to, but I won't put that much strain on my system since I never will in real world use.
From a cold boot, after 1 minutes at the desktop, what do you get from FurMark CPU burn after exactly 5 mins? (I'll go that long)

Hi, basically the temps shoot up to 72-75 immediately and hover around that temperature gradually creeping up. In a matter of 5 minutes, it stays a bit shy of 80 degrees. 

 

Note, I have power settings on high performance and tried it on balanced. In power saver mode, the temperatures are far lower. I assume this also has to do with downthrottling of the GPU, as in balanced mode i already set the max CPU to 99%.

Hold that thought. Installed an online platform I use for daytrading.. During setup and initial opening of the platform the temperature shot up to 87 degrees!!. This was in a matter of seconds. Fans did kick in around 60 degrees, but I am amazed by that fluctuation..

I run my system on the 'balanced' power plan. When I did my testing the CPU still shot up to it's max turbo frequency. I'm not sure what other power management it's doing but it might be worth a try. On the 'balanced' power plan my CPU maximum frequency was set at 100% by default.

I think my problem is as explained below.

 

https://forums.lenovo.com/t5/Lenovo-Yoga-Series-Notebooks/Lenovo-Yoga-710-710-15ISK-electrical-hiss-buzz-during-CPU-load/m-p/3395018#M43395

 

I have been using the laptop thinking the fans were basically this loud, but the hissing sound apparently is linked to buttons and mouse movements. It's probably the CPU voltage regulator. 

 

In power save mode, this does not occur, and the temps are far more stable...

 

Will contact Lenovo in regards to warranty.
