Re: Y50 Big fan pulsating and clicking

I installed multiple OSes including various Linux distros and Windows 7/8.
The problem persists across different OSes, so it's not dependent on what
OS you use.

Located in Europe, I have the fan sound on my Lenovo Y50-70,  256GBSSD, i7-4710HQ, 16 GB RAM.

Model number : 20378 , Bios version : 1.13

 

I sent my laptop to official Lenovo repair center, they changed the fans, but the problem is still there. Please Lenovo fix this.


Sorry, but how they did not tested new fans? For me sounds really bad job.

I wouldn't be interested in sending my laptop in for 3 weeks as I need it for work...

 

Doesn't Lenovo have these laptops available to them for testing?  I think they can afford it....;)

I've received several offers from members kindly offering to send in their machines to me, but unfortunately they are either outside the US or have made modifications to their Y50s.

 

With a laptop showing this fan issue from a customer in the US, I can not only open a case based on the information discussed here, but I can then verify the issue, walk it to the Level 2 guys in the building next door, see what they think, and follow up daily. Then I can show it to the Quality and Product Engineering folks and escalate, email, and "accidentally" run into them in the hallway for updates. I can work this issue from start to finish if I have a symptomatic Y50.

 

Still on the fence? As added incentive, I tracked down some Lenovo swag. If you send me your Y50, I will send you a Lenovo cookie (don't eat it - tastes bad) and a Lenovo twisty keyboard/display cleaner thingy! See the pic below. EDIT: Which has now been resized.

 

Thanks! PM me...

Re: Y50 Big fan pulsating and clicking

Hey there. I'm Mario.

I've got the same problem.

Windows 8.1. Updated drivers. 1.13 bios version.

 

I think the issue is due to the motherboard/fans firmware behavior.

I'm not sure thought, since I can't manage to have direct control on fans.

I tried with Speedfan. No information are given by the user interface. So I guess all the parameters are not "readable" nor editable from common software.

 

I think the problem here is like:

- the firmware check the temperature

- temperature > max temperature allowed for having the big fan to stay idle.

- start the big fan

- the firmware check the temperature

- temperature < max temperature allowed for having the big fan to stay idle.

- stop the big fan

 

And this start-stop thing keeps going making this annoying sound.

So, maybe, all it needs to have this fixed is more tolerance about the temperature range values.

Hope this makes enough sense to you guys.
