Re: Yoga 13 Fan Noise

2013-01-22, 8:30 AM

Hi Forum:

 

Just to keep things clear: this topic actually covers two problems, not really related to each other. 

 

1) Some noice from the fan-housing, which obviously must be fixed by physical repair by a service workshop.

2) The problem, that the fan is on constantly, even though temperature is low.

 

Just to not confuse the LENOVO team, I suggest that this is divided into two separate topics. 

 

The reason: the fan noise-problem obviously never could be resolved through some advice on this board from LENOVO (unless you are willing to totally disassemble your computer, bending the fan-house or replacing your fan, as sugested in a video, in this forum), while the other one actually might be solved by a firmware-update (BIOS or other).

 

So, adressing the latter of the two (sub-)topics: Lenovo, are you listening, and could you please give us some status on this issue.

It is bizarre that we still haven't heard back from Lenovo...

 

And still no one has replied to my question - does this problem affect ALL units? If so, I won't even bother to pick up mine from the store.

 

Thanks

Well, I don't think lenovo will admit that it is a hardware design issue.

Just as they don't dare to admit they were once the no.1 PC manufacturer.

realkouy:

 

That's why it makes sense to separate the two:

 

One hardware issue, that can only be solved by a repairshop (which is why we'll never get any response from LENOVO on that one, here) and one firmware issue, that (perhaps) can be fixed by an upgrade, costing LENOVO much less, than the potential buyers of the Yoga, they'll loose, if they don't invest some investigation into this issue.

 

It's all a matter of giving the poor people a chance to actually do something about a problem, that they (possibly) CAN do something about, instead of relating/mistaking this with a problem that they unfortunately CANNOT do anaything about (here), thus making it hard for them to flag at least one of the "fan-noise" problems as "solved".

 

After all the constantly running fan is (in my humble understanding) a more general problem, affecting all(?) Yogas, whereas the bad fan-housing is related to only a few (not mine for sure) bad assemblys, I guess.

Lenovo, never again. I will tell this to all my friends also, because Lenovo won't even bother to answer here.

Just here to tell my yoga also suffers from this problem. Fans are on all the time, and loud!

 

Manufacturing date: 12/11/27

 

Lenovo, when can we expect a solution for this?

So y'all know that there's a big empty spot in the Yoga where a second SSD can go... or maybe another fan... : ) Anybody want to take a shot at modifying the yoga to increase airflow and set up a lower RPM fan or two?

Wulftone,

 

Thanks for your continued efforts here in this thread!  

 

Richard, et all,

 

Sorry for being quiet on this issue for so long.   We've had a lot of internal dialog and generally the intent was to run one of the fans at low speeds to keep the system cool - around 40C by design.  This is working as initially designed and not a defect per se.  I know that there are a few examples where there may be some mechanical interference with the fan blades that makes individual systems louder than expected - we believe these are fairly isolated given the overall volume of units shipped and would recommend service for customers in those cases.

 

Your collective feedback that the fan is running too fast and constantly is not falling on deaf ears - we are exploring some alternate possible thermal maps and are trying to optimize to ensure we could delay the start up of the first fan without raising overall system temp, or triggering sudden ramp to high fan speed or frequent on / off cycling of the fan.  Hopefully we can release a future BIOS that can provide further optimization to the fan behavior - this is probably still some weeks away.

 

Best regards,

 

Mark

Thanks Mark, it's always reassuring to hear things like that.  The natives can get very restless quite easily.  : )

Mark,

 

Thank you for the response. Its nice to know this is being looked into. A small anecdote for consideration. I let my  father (who is not very technologically advanced) use my Yoga 13 while traveling this weekend. After about 15 minutes of use, he handed it back to me worried that he had broken it. He said that the fan had been running the entire time and he thought something was stuck.

 

While I doubt I will return my Yoga, I would still like to see this aspect improved on.
