Re: "Solutions"

Hi Doraemon,


I think your heatsink is the solution I really love for my S10e. I have found right copper thickness but it is not cheap so I wonder if you have any template/dimensions of the heatsink you made, just to make sure I do it right first time :o)

I would really appreciate it!



Best Reagards,

[S10e] BIOS 14cn96ww improves fan noise (imho)

2009-12-24, 11:12 AM


I wanted to give a positive feedback. I purchased an S10e some days ago. The noise of the fan was a bit annoying... I would call it "digital". It seemed to only knew full power or nothing... as described in dozens of posts.


I checked the Bios Version, it was something in the 50ies... I upgraded to 14cn96ww and think its much better now. The fan is running a bit more often, but at lower speeds. Additionally it doesn't change speed that fast and often. From my personal view, this is much less nerve-wracking...


(Wow, when I read the history and the number of complaints, this topic is similiar to the Screen Flickering issue of Lenovo X60)

I have red almost all post but I did not find any solution. My cooler is still wery loud. I am thinking to sell netbook which is old only a few days. It's a shame for company to have so many unsatisfied costumers.

Re: [S10e] BIOS 14cn96ww improves fan noise (imho)

Wanted to add my experience of owning an S10e-4333 with fan problems out of the box. Both of my fans (CPU/Chipset) and PCI-e slot fan were grinding. The same noise you hear when your desktop fans start to become low on oil or their bearings go bad. The noise was unbearable and I knew right off the bat they were busted. Coupled with the fact that shortly after boot-up, they ran constantly really sucked.


Went through heck and a month of sending to/from depots due to various screw ups on Lenovo's part. FINALLY got BOTH fans replaced and they upgraded the BIOS to 96 from 94 for me. After it was finally fixed for good, my s10e was really quiet and I'm delighted with it. The "96" BIOS update really made a difference in how the fans run. The CPU/Chipset fan runs at variable RPMs now and not full throttle on/off/on/off all the time. Also, the 2nd PCI-e fan doesn't run much at all. Maybe every 30 minutes for a minute or two and shuts off.


Overall, my s10e is quieter than many laptops I've worked with. All you can hear is wind whirring if you put your ear up to it. That's it. Just using it normally on the table or in my lap, I can't hear much of anything. Maybe the slightlest pick-up in wind noise when the fans spin up to full RPM.


I suspect quite a handful of the posters in this thread are hearing their fans buzzing/grinding and should probably have them replaced if possible.

Got my s10 more than a year ago. Noisy fan issues started happening 6 months after purchase. I also have a T61 which displayed a fan error message out of the box, worked fine after a restart, and now has the noisy fan issue and high temps.


Learned my lesson and didn't buy a Lenovo branded notebook for my recent purchase, and won't be buying any Lenovo product ever.

I think the fan kicks in far too early. From the temperatures I see this is the problem. It could be that the sensor is too sensitive and the threshold is too narrow for turning the fan off an on. Hence the constant cycling.

I think Lenovo's problem is that this is a motherboard issue and they won't re design it to help with the fan issue.

I cannot recommend it, but I see no reason that web surfing would ever cause the Atom CPU to reqach its 90 degree celcius temp threshold. Even without the fan. This is in fact a very low powered chip. Seems to me that a better heat sink would have prevented some of this.

98 pages of absolutely useless topics.

How long it takes for you to realize that Lenovo has no solution for this problem?

If you like to see your name here, keep post!

If you are just a little beat realistic, leave it like this. Lenovo does not give a penny on yours oppinions. :womansad:

Re: S10/S10e Fan Problems - Collecting Info for Lenovo

Hi all.


Im having the same issues with my S10e. Just opening MS Word and the fan goes on to middle to high, which is too loud to use in


a College Seminar if I dont want to get angry looks from fellow students who are annoyed by the loud noise. If I try to


open Thunderbird with MS Word running simoutaneously it goes to high and it gets really irritating even at home.


Just my 2 cents on this matter. Im planning on selling it, as it is nearly mint.


Best regards
