Re: Yoga 13 Fan Noise

Sometimes when the fan is noisy, I find in the task manager that conexant audio messenger is having a high CPU usage. So I end the task, and the laptop stops making noise almost instantly.

Re: Yoga 13 Fan Noise

I just figured out what the problem is - but I cant provide a solution.

 

It's NOT the CPU. Its the SSD which makes your fan go crazy.

 

There are two triggers which will start your fans.

1. Both cores are getting hotter than 36°C

2. The SSD is getting hotter than 24°C

 

When you turn on your system the CPU cores and SSD are fine. No fans are running.

When starting some software or apps the cores get warmer and finally reach 37°C or more. The fans start running.

After a few minutes the temperature of your cores is under 37°C again and your fans turn off.

 

While you are working on your yoga the fans will start at some point to run permanently. They wont stop again.

Thats why your SSD gets hotter than 24°C and wont get cooled down by the fans.

That means that the fans cannot cool the SSD. It gets hotter and hotter instead of getting cooler. 

As a matter of fact, your cpu is fine but the SSD gets crazy. Because it gets to warm your fans run at full speed but they just dont cool anything but the CPU. The running of the fans has no effect to the SSD temperature and thats why they keep running - because they want to cool the SSD down but they cant. The side effect of this is that your cores will also get hotter and hotter because the SSD gets hotter and hotter. So your whhole system gets too hot because the fans dont cool down the SSD.

 

As a result I am very sceptical about a BIOS patch. The fact that the fans wont cool the SSD cannot be resolved by some software. Its a hardware thing.

 

Sorry folks for destroying your last piece of hope :/

 

// EDIT

Oh wait!

There can be a software fix (hopefully)

The SSD wont get hotter than 30°C (which is not very much)

So if you set the first trigger (CPU) to about 45°C and the second one to 31°C (or remove it completly) your fans should stay calm. (more or less)

I'm pretty sure that solid state drives produce very little heat but I could be wrong!

When you say HDD do you mean SSD?

 

How did you get this information? by testing? 

 

If Lenovo could just remove the SSD temperature limit and raise the CPU temperature limit, then it *could* remove the problem!?

Yeah with HDD I mean ofc SSD.

30°C is not much in my opinon.

And yes, by testing serveral times.

 

I think removing the SSD temperature limit and raise the one for the CPU will fix the fans from running 100% all time. Instead the fans will run when the CPU gets to hot, cool it until its fine again and than stop until it gets too warm again.

 

A graph for the fans running would look like the sine graph.

copa: Nice work!

 

-Now if just the Lenovo ingeneers would fix it or give us an application that would enable us to adjust the parameters ourselves....

Most SSDs don't include thermal sensors.  Can anyone who has removed the stock SSD confirm the fan noise level or run SpeedFan to check the temp sensor?  That should confirm whether Copa is on the right track.

Is there any software to fake/change/write the SSD/HDD temperature?

I guess this is another reason to test out my question about having an external fan, ie. laptop cooler. My Yoga should be delivered soon, and I hope it doesn't have any problems, but if it does have the fan-on-all-the-time issue, I'll see if my old laptop cooler for 15-17" laptops will affect it any.

 

I'm sure someone else must have one already to try this.

Just found this: http://forum.crucial.com/t5/Solid-State-Drives-SSD/M4-temp-exceeds-100-C-on-Intel-Desktop-Utility/td-p/91278

Short version: Crucial SSDs does not have a temperature sensor. But I am not sure if it actually is a Crucial SSD that sits in the Yoga...
