@lugig

 

I fully agree with you. It's the whining that makes the pulsing audible, and no software solution can remove the characteristic 2.2 kHz tone of the fan motor. Luckily, there is already a hardware fix for this: Not every machine is affected by the whine, which means that high quality fans are being produced already. Come on Lenovo, offer us something real - we are tired of being test pilots....

Hi nesnhoj,

welcome to this forum!

When did Lenovo change your fan?

Did they tell you what they think is wrong with the motherboard?

From what you are saying it looks like Lenovo still has no clue what is the root cause of this problem.

bristiankoye,
based on the report from nesnhoj (#299), Lenovo is still not able to differentiate between the good fans and the bad fans. Getting a good one is like winning a lottery (at least in Norway) :smileyhappy:

I am also very curious about the reasons behind replacing the motherboard because of the whine/pulsing issue.

Strange. My fan runs at a steady speed all the time, and the power controls say the fan mode is "Maximum Performance" I'd report the speed, but I don't know where to look for it.

Hi, and thank you! They changed it for just a couple of days ago. Have to say that the service dep that are executing the operations is not lenovo staff, and they are just doing the hardware so its a bit strange but im just using my onsite service agrement. Hope there will be a soulution very soon from lenovo. Its a shame, four weeks today since i got it today. The nois/whining/pulsing is so enoying that i have not used it at all...

That sounds scary.

 

Any X220i i3 users here having these issues or is it mostly just a X220 issue?

Hello, some update from me. The 1.6 BIOS reduced average fan speed but didn't reduce the fan noise when running at higher speed. This does occur very often though. But to work in "Turboboost+" mode is nearly impossible due to the fan. 

 

I don't hear a fan pulsing, but I can feel and hear a buzz every couple of seconds (irregularly). It seems to be located under the D and F key. This is not disturbing but I just wonder what it is.
