Re: X220 High Pitch Noise / Whine - Misconceptions

2011-11-11, 20:08 PM
It has been absolutely confirmed that the CPU can produce a whining noise with the fan off. The CPU may not necessarily generate an audible sound at that frequency, but it may produce harmonics or other components that produce a sound that is audible.

Lenovo knows about the CPU whining on the Arrandale generation and offers a motherboard replacement under certain conditions. It's not very prevalent on the Sandy Bridge generation.

The fan has indeed been known to generate a high-ish whining noise at higher RPMs. This is different from CPU whine.

I know certain Arrandale topologies had acoustic problems in multiple products.  I don't know that it was ever proven to be the CPU, SMPS, or other components.  In any case, it's not relevant to new X220s.

 

The pitch can be modulated by removing the keyboard, putting the CPU under load to spin up the fan, and applying light friction to the fan blades.  The audible frequency decreases in proportion to the rotational speed.

This will be my last ThinkPad. Still no solution for the fan whining, even no acknowledgment or fan replacement offer for customers who feel extremely bothered by the noise. At the moment we can only help ourselves by using external software like tpfancontrol, but this only helps as long as the CPU isn't stressed. Everything above fan level 1 creates this annoying sound.

So which comparable machines have quieter fans?

Hint: Not the premium-priced SonyVAIO Z:

 

"Unfortunately, the VAIO Z's fan got pretty loud at times, especially when under a heavy workload. While installing a demo of the Homefront game with the Power Media Dock connected, the laptop sounded it like it was getting ready for takeoff." [Laptop Magazine]

 

"Throughout our testing, though, the fans spun so noisily that someone sitting nearby in our office stopped what he was doing to express concern. They became particularly insistent while we played Call of Duty 4 (and this was even after we lowered the resolution from 1080p to 1024 x 768)..." [Engadget]

 

Under the circumstances, Lenovo seems to have actually done pretty well, our ThinkPad expectations notwithstanding.

After all, There Is No Magic.©

I'm personally quite satisfied with the quietness of the X220.

Guys, have you tried  TPFanControl? I'm using it for about 1 month and it works perfect for me. When I use "Maximum Battery Life" option, my fan doesn't spin at all and temperature never go up 62 degrees! The noise that I can here is my HDD(which is sounds good for me ^_^ ) and my breath. What is more, after I've update Lenovo's Power Management TPFanControl teamup with it just fine, there are no any uncontrolled reboot or whatever.

Re: X220 High Pitch Noise / Whine - Misconceptions

Guys, I have a X220T and, like many others, I had the same problem with the fan (continuous whining). I had it replaced last week and I have to say that this new one is way quieter and silent.
The only problem I have is that since roughly a month (I don't remember if it was after a BIOS update) I am not able to read the fan speed anymore (using softwares like SpeedFan, HWInfo, AIDA64, etc...). Does anyone know why and how eventually re-enable the fan speed reading?

Thank you all.

Claudio

Re: X220 - fan constantly on / revving up and down

2012-05-12, 22:53 PM

Hello,

 

Has this thread closed its debate because there is a solution to the problem? If so, what is it?

 

Can anyone adivse what are the options for an x220 owner that can't stand hearing the fan whine all the time when he's working with the laptop and keeps imagining he hears it when he quits working with the laptop?

I'm using bios 1.29. Is there a bios version that solves this problem?

 

Does giving the machine to the service in order to replace the fan helps?

 

Are there any similar fans that might be installed on this laptop that will solve this problem? Maybe a fan with similar dimensions but of better quality?

 

Please reply. I can't enjoy my laptop experience. I can hardly even work like that.

Thanks

My X220 (June 2011) with all updates applied did not exhibit a significant fan problem. Under normal loads fan noise was usually not noticeable (faint rushing sound). Under heavy loads there could be a slight whistling sound, but it was quite a bit less than comparable machines, including my current T420s. If your fan noise is objectionable and you have all updates applied, then I suggest you have it serviced under warranty.

My x220 is brand new (although maybe the model is old, 4291-5DG, i5, 320HDD 5400 rpm). I bought it a month ago.

It came with bios 1.26 and I updated it to 1.29, but the fan still whines at 2200... 2500... 3150... 3600... rpm although the temps are only 45C.

Are there any other updates I should install besides the bios upgrade?

 

I'm afraid if I try to explain myself to the lenovo service people they would blow me off and tell me there's no problem and that's the way the laptop should work.
