Re: Y50 Big fan pulsating and clicking

2015-03-08, 16:52 PM

And I am really shure, that the user messured the themperature in a way that makes it accurate enough for you to print it :D

Okay, the cpu temp can be messured accuratly ;) 

 

I think it's good that security related problems are solved faster, than other problems, and I can imagine, that a huge company like Lenovo has some slow internal processes. I am also glad that the clicking is beeing looked afer.

 

But the solution on this takes verry long.

I experience the same thing - bearly audible, but annoying clicking noise coming from the case at certain temperature.

 

I believe there is nothing to be worried about - this is quite typical for PWM controlled fans. It happens even in case of top-notch fan manufacturers like Noctua. The only solution would be to replace the fan with a different model, and even then there is no guarantee, that this would help.

 

The good side of the story is that this is not a symptom of a bigger problem.

As a result of these reports, a BIOS update was released today that should resolve the fan noise reported here. Win 7 32-bit, 64-bit, Win 8 64-bit, Win 8.1 64-bit are supported for the Y50-70, Y50-70 Touch, and the Y70-70 Touch.

 

You can find the new BIOS on the Lenovo Support webpage: http://support.lenovo.com/us/en/products/laptops-and-netbooks/lenovo-y-series-laptops/y50-70-notebook-lenovo

 

I look forward to hearing your feedback on this solution.

 

Thank you,

Thanks! Just installed it, everything seems to work fine. But this needs
a few days to be safe to say.

Fix confirmed. Just been testing it roughly 15 minutes with speedfan running and watched the temps. 38 c at the lowest temps and no clicking, before it started clicking at around 44 - 43 c and below. Good Job, and THANK YOU!

Just installed the BIOS update. So far, I think it's working! I'll take some time to make sure that it keeps working, but for now it seems great! Thank you!!
