1.A bios and smart fan

i recently updated to the newest bios (1.A) and now it seems my smart fan tolerance entry in the bios setup screen doesn't save.
i set it to 1 (the default is 5) ... but as soon as i save the changes and the machine reboots, it reverts back to 5.
other changes that i make here remain.. only this one always reverts back.
anyone else having this problem??
i can't get my noisy fan to slow down now and be more quiet!!
Edit: forgot to say that i have an MSI K8N Neo2 Platinum

yeah... i could use speedfan, but it used to work with the bios controls -- so i expect it to work now.
also, it's a pretty strange problem, why doesn't it save the tolerance in the bios settings, but is ok with everything else?
anyone else have this problem?

G580 and Smart Fan Control?

Hello all,
I just purchased a Lenovo G580 laptop. There is a sticker near the keyboard about 'Smart Fan, Noise Control'. But so far I have not been able to find out how to use that feature. AFAIK, some earlier Lenovo models did have a separate touch button for this feature. Is the user supposed to be able to control it at all in G580? There isn't anything about this in the user manual.
Lenovo Energy Management software gives me some kind of control over the efficiency of the hardware. But to me it just seems to replicate the selections I make with Windows' own power management options. Fortunately the machine is relatively quiet in itself. But particularly when listening to music it would be nice to make the fan as quiet as possible - to my knowledge playing back FLAC files is not a very demanding task.
Thanks in advance for any advice.
Solved!
Go to Solution.

Dear lenovo support,
As we have said, and as you MUST already know (since you made them), the user guide, the sticker on the demo laptop at retail stores, and the same sticker you see on the laptop you purchase ALL SAY IT HAS "SMART FAN, NOISE CONTROL". However when reading the user manual, or looking at the laptop itself it is abundantly clear that THERE IS NO NOISE CONTROL BUTTON.
Clearly the reply saying the original post has been solved was in error. Normally I would be ok with that if you had bothered to fix it or apologize for some kind of "clerical error" by now. Your customer care is reminiscient of microsoft. This is not anything you should be proud of. I don't think, but KNOW that you need to either admit the G580 doesn't have the features in question or explain how we can use/access them.
This is a simple issue. This has been addressed with incorrect information. This has since been determined to be the "solution". If you cannot resolve something this SIMPLE, what should I expect if I have a serious problem? Well, I don't want to have to find out.
If this thread doesn't get either an ACTUAL informative response, or a simple apology I will return my laptop. I will use my money to purchase another, non-lenovo laptop. I will never purchase another lenovo product. I will advise everyone I can, whis is substantial as I work 6 days a week doing home and buisness tech support, not to purchase lenovo products. With this in mind, I eagerly await your quick response. I do not have long until my 30 day window expires to return it. I have been waiting for a response to this since I bought it.

H61MU-E35-B3 and smart fan....minimum fan speed

Hi, I installed a core i3 2100 to this board. My cooler is a Scythe Grand Kama wich cames with it's own fan. I set smart fan to target:50° and minimum speed of "0". Even tough the temps idel way below 50° the fans rpm is always aroun 620. Why does it spin so high, since i set it to 0????
thanks

ok, it's the fan....It wont run below 622rpm.

MS-7173 fan speed - bios v1.2 - smart fan BIOS setting

Hi all,
I would like to know if there is any possibility to set smart fan in BIOS on the MOBO mentioned above to lower than 60C.
My goal is to reduce fan RPM, because now it runs at 1400RPM constantly. I have read numerous MSI forum pages and other pages as well, where people are advising to set smart fan to lower values like 35 or 40 degrees, what would perfectly solve my problem. But I can only set it to 60C min!
Does this setting have to do with my BIOS version? I recently used MSI Live Update to get the latest official 1.2 version, but it did not help with this setting. Still the same.
Here on the MSI pages I found threads related to this MOBO and BIOSes and I found something like this:
https://forum-en.msi.com/index.php?topic=108946.0
Alternatively I read something about versions 1.25 from some czech forums, and a BIOS from MaxData. Those were mentioned always only in relation to Vista and Win7 installation. But I only want to change the smart fan setting. Is flashing of those BIOSes adviseable?
Sure, I'll have to try i guess. But I don't want to unnecessairily brick my MOBO or do a useless upgrade.
General question: Is there any way to get to set the smart fan value below 60C in BIOS?
I only managed to reduce the RPM in Ubuntu with lm-sensors and fancontrol, which is kind of a workaround, but I am searching for a more general way.
Thanks alot!

Hi guys, I stumbled across the solution while trying to fix something different
The ultimate solution for my mobo was to flash the MAXDATA bios mentioned somwhere here in the forums, can't find the link right now. After that a plenty more settings appeared in the HW Monitor BIOS page and the CPU fan speed is now by default 740RPMs, without changing anything tadaa!
Don't worry, nothing will by fried, temps were not moving above 45C. Now the smartfan is kicking in at 55C, what did not happen yet..

MSI Z97-G45 Smart fan control Bios v2.0 vs Bios v2.3

Hello
I have an MSI Z97-G45 Gaming motherboard in my new setup with 4ghz i7 4790k and 16gb of ram and so on that i bought a few weeks ago. At first the motherboard had v2.0 Bios and everything worked just fine but as i like maximum compatability and other fixes i upgraded the bios to the latest one v2.3.
In my setup i use the bios smart fan control for both system and CPU fan, i set it at a curve where the fans instantly will rise the fan speed when doing tests like Prime95 and Aida64. When doing the tests the fan rised from idle 800rpm to neded fanspeed for the correct cooling for my CPU and reached maximum 1500rpm in a matter of seconds to keep the CPU cool. This worked perfectly with Bios v2.0 but after i upgraded the bios to v2.3 the smart fan control changed fanspeed extremely slowly, it took almost 50sec for the fan to speed up from 800rpm to 1500rpm when stressing the CPU at 100%. When i stoped the stress test the fans slowed down to idle 800rpm very fast with bios v2.0 but with bios 2.3 i took a looong time to slow down to idle speed again from 1500rpm.
Because of the slow changing fanspeed in bios v2.3 i downgraded to v2.0 again and then my fans works just as i want them to do.
What is the reason for this problem/change in bios v2.3 and will this be fixed in future versions? Is this a known problem with newest bios?
When people will buy this MB and it has v2.3 from factory the smart fan control will not work properly and buyers will not know how good it can acctually be. I think the Smart fan control in v2.0 is super great

BIOS Update and now fan is running constantly

I got a HP Pavilion 15 Notebook PC last week and have just been prompted to install a BIOS update. When it was installing the update the fans turned on and were deafening.
It's installed the update, restarted itself a few times, etc.
However the fan is now running constantly and is extremely annoying. It's not blasting out by any means and is probably nowhere near how quick and loud it could be. But this is a brand new laptop and the fan shouldn't be running - all I'm doing is browsing the internet.
What has this update done and how can I turn the fan off (I presume it will turn itself on when the heat inside the laptop requires it).
Cheers

MSI FM2-A75IA-E53 Over cooking bios and fan setting advice

Evening.
Slightly bizarre problem in that my machine wants to fry itself when in the bios. I put together a new build of the FM2-A75IA-E53, AMD A10 5800 and a Noctua NH-L9a.
In windows 8.1 it will sit at a healthy 35-42c when web browsing etc but when I enter the bios it rises quite quickly to 60c before I restart the machine (I'm sure it would continue until shut down/reboot). The temperature settings I believe to be correct as I can hold my fingers on the heat-sink and feel it burn.
It's not a big issue as I don't plan to spend anymore time in the bios than whats required.
My next thing is if you could advise me on bios fan settings, I'm running cool & quiet (Trying to think what other settings I have,12.5% and 50c rings a bell) Sorry I could save this text and reboot but I'm lazy. Click bios for some reason requires a fresh install each time to work (It doesn't over heat BTW). I guess what I'm looking is ideal settings to keep the machine cool & quiet. I should point out that when the bios was over heating I wasn't running cool and quiet settings and the fan was over a constant 2,000rpm. At the minute as I type it's 45c at 1100rpm and that's packed into a tiny Lian li PC-Q03 and it's been running a few hours now watching 1080p YouTube vids.
Ohhhh and while I'm here, any sign of 8.1 Wifi drivers?
Best regards
Bap

I would suggest either doing it through regular bios instead of click bios, or double checking that you are actually saving it via click bios.
I have my speedfan set to be 12.5% min and kick in around 50 or 60 (quite high, but when the processor itself is so much lower I'm not concerned).

Can someone explain 4pin smart fan PWM to me?

I have a 890FX-GD70 running BIOS version 1.2 and I have my 4pin CPU fan plugged into the 4pin header. I see in BIOS that if I enable Smart Fan I have the choice between 40, 45, 50, 55, and 60 as "CPU target". I have no idea what those numbers mean. At first I though they were temperatures, so I chose 50. Then under CPU fan min. speed % I also chose 50, thinking my fans would spin at half speed until my CPU reached 50C, and then would ramp up. That does not happen, so I must be misunderstanding something.

Target temperature in degrees celcius. Use 50 or 55°C.

Satellite A215-S4757 - Battery life and cooling fan issue

Hello everybody,
I would like to ask a few questions abou my system: first of all, the cooling fan is running in my opinion too often: almost continuously, with brakes of 2-3 seconds. Is this normal?
I have my laptop since august last year and I think it shouldn't be a problem of dust, because it is too "young" for that and I don't live in a "dusty" appartment...
Anyway, I think the "almost allways running fan" problem appeared about 2 months after I purchased the notebook. I have installed "Speedfan" and I see "HD0" temperature is increasing from about 30deg immediately after I start the laptop, to about 39deg after 1 hour.
But the curious thing is that so named "Core" temperature is oscillating from the beginning between 45deg and over 52deg! The fan starts each time the core temperature is rising over 50deg and stops when the temperature reaches 45deg. Is this behaviour normal???
Is the core temperature of 45-50deg normal? I am just using my laptop for Internet browsing, e-mails, etc., no complex 3d games!
The second thing is that the battery life is (and was from the beginning) not spectacular: it lasts max. 1,5 hours with wireless on, but normal use of laptop (not playing dvd's or something like this). Is this normal? If yes, is it because of the amd turion 64x2 processors?
Please help me with some advices / opinions.
P.S. I've bought my Toshiba as I was on trip in USA (NY).
Thank you very much in advance.
Conrad

> I would like to ask a few questions about my system: first of all, the cooling fan is running in my opinion too often: almost continuously, with brakes of 2-3 seconds. Is this normal?
Im an owner of a Satellite A210. Its similar to the A215. The A210 is a European model and the A215 belongs to the US notebook series.
I have noticed the same on my A210 and I think its normal behavior.
> But the curious thing is that so named "Core" temperature is oscillating from the beginning between 45deg and over 52deg! The fan starts each time the core temperature is rising over 50deg and stops when the temperature reaches 45deg. Is this behavior normal???
The CPU temperature of 40-60deg is nothing unusual.
The temperature could arise up to 70-80degrees while playing a game. So dont worry about the temperature.
The cooling modules are controlled by BIOS. The fan table is stored in the BIOS and it contains informations about temperature limits and the cooling usage.
If a certain temperature level was reached the cooling module starts to rotate with a certain speed.
Now I would like to say something about the notebooks battery life time
Generally the battery life time depends on the notebooks usage.
While playing games or watching movies the battery would discharge much faster.
Anyway, your notebook was equipped with high-performance devices and as far as I know the Vista was preinstalled on this series. Both factors (high performance devices CPU and GPU) + Vista OS need a lot of battery power. Vista needs more notebook resources as the Win XP and therefore notebooks with Vista OS run shorter on battery as the notebooks with preinstalled Win XP.
Last but not least you have to know that there are different battery models A stronger battery with higher *mA* value would help to run the notebook longer using the battery power.
Hope I could clarify this question.
Bye

Experiment and conclusion on notorious Bios and turbo boost related issue.

Hi everyone,
Like everyone here, I suffered from the turbo boost issue and I decided to find a practical way to solve this problem,so .I conducted some experiments trying to find out the relationship between power strategy, graphic type, booting power source and the CPU frequency.. Here are my results:
Variable: Power strategy for AC/BAT: Max/Balanced, Max/Max(didn't try for balanced AC power strategy)
Graphic type: Integrated, discrete and Nvidia Optimus
power source when the machine booted(BAT,AC)
Testing model: W520 42762QU i7-2720QM Quodro2000M 16G Crucial M4 128G, 500G HDD, BIOS1.30
Testing programs: Intel Turbo Boost programs and CPU-Z

Notice the '800-2400' state, it is a special situation when CPU-Z occationally gives me a speed of approx 2400 when I tried some head-load programs, which lasted about few seconds and the frequencies went back to 800 or 1500(in most cases, 800) when I closed the program.
Conclution:
1. power stratagy will not influnce the cpu frequency.
2. booting power source and graphic types will do.
3. I'm sick and tired of pluging and unpluggin my W520.
4. I'm not a fan of Nvidia Optimus.
5. Lenovo did a terrible job on this issue.
6. I expect a same result for Bios 1.26
Practical solutions:
1.When you need a powerful W520, use Discrete graphic and plug your AC while booting.
2, For a longer battery life, use integrated graphic, and if you wan't to plug the AC, please turn off your machine and boot again.(not rebooting!)
Thank you for reading my post and sorry for my bad english

SomeOtherGuy:
Thanks very much for keeping us all informed about the "work in progress" on the BIOS and the Turbo-thing. That is thoughtful of you and will (hopefully) cut down on the amount of carping and complaining about this issue.

G580 Smart Fan Noise PLZ Help me Any One...PLZZZZZZZZZZZZZZzz

PLZ help me. My lenovo g580 When power on ..Just hearing Noise . Its Smart fan Noise. Plz Help Me Bro...........

hi Arif664
Welcome to Lenovo Community Forums!
You may want to try a software Called speed fan, This gives control to your Fan and also shows Temperature readings.
Other Lenovo Motherboard have Restrictions for controlling the Fan. But give it a shot If it detected your fan then you're all set. adjust the Fan to your desired speed and fine tune it with the Temp that you're getting
If the Fan really get too Loud, beyond normal, I would still suggest to call Lenovo Technical Support for Assistance.
