New Ideapad U310, how to reduce fan speed?

Hey everyone,
I got a new ideapad U310 this weekend. I'm very happy with it, accept for the fan. It seems to go fast for no reason. I found some old topics on this forum, one with a bios update, but it does not seem to work anymore on the current bios version unfortunately.
Can anyody please help me? The fan noise is very annoying and after 2 days of working with the ideapad I rather have it turned off to get rid of the noise than continue working on it.

Hi schildpad00
Can you clarify more, which model exaclty you have ( S310 or U310 ) , and also do you play a games while the fan makes that noise
Please let me know
Thanks

How to control fan speed on Satellite A660-11M?

please any body know how to control fan speed its always 69% and make bad noise and the cpu usage is 3% no at high processing i try advanced power settings but still runing at high speed

> I hope u didnt expect that they were gonna stay at 0% like forever
Of course I dont expect this. When you switch on the notebook CPU reach high temperature in few seconds only and you must not wonder if pretty high CPU temperature and fan activity will be shown very soon.
I dont know what do you expect but it is logic that cooling fan will run. Maybe all time maybe will be cut off for short period of time but it will run permanently. I dont see any problem there. With cooling method option it can be reduced a little bit.
And what is your question? I didnt understand what you want to know exactly.

Reduce fan speed below default

Is there any way to reduce fan speed below the default values of 2000 rpm? I want to do this on a trial basis only to isolate some sources of noise.

This does not override the SMC controlling the fan.
Right. I was just trying to imply that for the users who may read this thread (or stumble across it through Google) who are not expert users should not be attempting to modify plist files to change their fan control settings. One wrong move in there (like putting 1000RPM in for the max speed instead of minimum, as you've said) could result in damage to the machine that their warranty would not cover. It's way too easy for the inexperienced user to accidentally screw something up that could seriously damage their machine.
Just to be clear: I do enjoy reading about the more "technical" way of doing things (like you've posted) but some people in the forums may interpret this as something that they can just do "willy-nilly", and I don't consider it to be like that at all. Only expert users should consider doing something along these lines.
Thank you, though, for sharing the method. I do enjoy reading things of this nature!

Bios Update to reduce fan speed at first level for t430s planned?

As everybody here now about the hight rpm of fan at first level (ca. 3000rpm). Lenovo changed that with bios update e.g. for T430. As I notice T430s has no update reducing the speed at first fan level.
Does anyone now if lenovo plan to bring an update to reduce the speed on T430s too?
Or will be no change for that?
Thanks
Stephan

Request MSI GTX 770 Lightning reduced fan speed rom edit

Hello,
If someone can edit or provide an edited rom with a reduced idle fan speed to 20% (from original 33%) that would be greatly appreciated.
BIOS : 80.04.C3.00.38 (P2005-0000)
Please pm me if you need a copy of the gtx770 lightning base rom
Cheers,
N

So I bought a new cooler - Prolimatech MK-26 and two Noctua F12 fans. I connected the fans to the fan connector on the card and... !? I can't set the fans to less than 1000RPM! Even though these fans can spin at 300RPM and even though the temperature of the GPU is around 30C. So the card does not limit the fan speed settings, it limits it's rotation speed to 1000RPM. And this limitation doesn't seem to be in BIOS.
So if you want a really silent GPU, DON'T BUY NVIDIA!!! This limitation is stupid and it has no sense (it's not related to temperature), even the stock cooler would be deadly silent in idle without this "feature". Those two F12s can cool this card down even in afterburner, with power limit set to 111%, boost clock all the time.

Brand new 5850 twin frozr II idle fan speed loud!

I've just got a new one of these and just put it in and the fans idling at 55%
idle temps are 30-31c. So why the hell would you fan spin up to 55% to cool down from 30c
I had a sapphire 5850 and I had an xfx for crossfire which busted so I opted for the msi twin frozr becuase it has had many good reviews
I can put the fan speed down to 22% in afterburner but as soon as I put it back to auto it goes straight back to 55%.
I have tried un installing CCC + drivers and removing all ATI related folders then re downloading from the ati website but that doesn't fix it.
Any ideas?

Explain the issue to msi tech here: http://support.msi.com/
they can send you updated vbios to resolve it
Quote from: ewarwoowar on 29-January-11, 22:02:10
I've tried the live update utility and it doesn't pick up any new BIOS for it.
No where else I can get them from as its saturday and they only reply monday-friday
If the card is working fine otherwise, then have some patience and contact MSI support for the updated BIOS, as Svet already recommended.

How to increase fan speed on HP pavilion dv7

i have a major problem with my fans on my pc. It often reaches 80-90 degrees celcuis, when i have been playing a fairly simple game for about 20 minutes. does anyone know what to do? and it dosent seem like i can increase my fan speed in any way. i have been trying almost everything i can find on the internet. please help

Hello themanafreak. I understand your notebook is getting warm during use.
First, you should ensure that the cooling system of the notebook is free of dust and debris but cleaning the notebook as per these instructions.
Also, another good step to take is to ensure that you have the latest version of the BIOS installed. I can locate the latest BIOS for you if you provide me with your product number. This document can show you where the product number is located. Finally, I do not know of a way to increase the fan's speed itself but you can set the fan to "always be on" by doing the following.
Reboot your computer and press F10 until the BIOS loads.Navigate to the System Configuration section.Ensure that "Fan Always On" is set to enabled.Navigate to the Exit section and save your changes.
Have a great day!

How to change fan speed on Satellite P100-286?

Hi,
First, know that Im French so sorry for bad English I may use,
I work in a confined area with some other computers, and, it becomes pretty hot in there...
My P100-286 (Ive also seen it called P100-473) is quite hot and I want to speed up the fan manually because it seems that the OS I have (Vista SP1 or Debian in dual boot) can't do it and the problem is that the CPU, and probably the geforce, are heating the keyboard and this is really unpleasant ...
The BIOS setting that manages fan is already set on "performance mode" but this is not really better....
So How can I make fans turn at full speed?
Thanks

> the problem is that the CPU, and probably the geforce, are heating the keyboard and this is really unpleasant
The point is that the P100 was equipped with high performance CPU and GPU and both devices produce a lot of warmness.
May I ask you what graphic driver you have installed?
The original Toshiba graphic drivers support an overheating protection and this helps to decrease the GPU performance and to reduce the heat output.
The non-Toshiba graphic drivers dont support such protection and therefore using non Toshiba GPU drivers could lead to the higher temperature.
Greetings

How to reduce motion speed?

hi,
i have a title with some text on it.
one of my effects moves the text from one location to another.
another effect changes the opacity from 0 to 100 to 0.
the title in question is 2 seconds long.
when i play the title, the text is moving TOO FAST and i would like to SLOW IT DOWN.
increase the duration or decreasing the speed will only double the length of the clip and this is not what i want.
how can i reduce the motion of the text but yet still keep the length of the clip the same?

How did you adjust the Position of that Title?
If via Keyframing the Fixed Effect>Motion>Position, just alter those Keyframes.
If you used, say the Title Crawl Preset, I would delete that Preset, and instead use Motion>Position Keyframes instead.
Good luck, and let us know a bit more about what you did.
Also, 02 secs. is a short Duration, especially if you are starting off-screen, and ending off-screen on the other side of the Frame.
Good luck,
Hunt
PS - I do my Titles, so that the viewer can read it completely 1.5x, and if it's in constant motion, will make that at least 2x.

How to increase Fan speed | HP Travelmate 8510p

Hi everybody,
I post here because I have an issue that last from more than year with the temperature of my CPU. It's always near 50/60 when I'm lucky, and it can go to 90 degree and make the laptop crash when I'm running costly applications (like compiling stuff or playing games).
I would like to force the fan to run faster, like it was when I was running windows on the same laptop, so that the CPU (and also at the same time the keyboard which is burning my fingers) stay cooler.
Here is a sensors I just made :
DeepThought# sensors
radeon-pci-0100
Adapter: PCI adapter
temp1: +39.0°C
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +61.0°C (high = +105.0°C, crit = +105.0°C)
Core 1: +63.0°C (high = +105.0°C, crit = +105.0°C)
So it's seams the issue is realy the cooling of the CPU.
I tried stuff described here : https://wiki.archlinux.org/index.php/fan_speed_control but it seams I havent any PWM control on my laptop, or otherwise some drivers are missing :
DeepThought# pwmconfig
# pwmconfig revision 6166 (2013-05-01)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.
We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.
/usr/bin/pwmconfig: There are no pwm-capable sensor modules installed
So if you have any advice, any method to try, I'll be happy to hear about it
Thanks,

The output is empty (nothing found).
> - Disassemble the laptop and replace the old thermal pads / thermic paste with new thermic paste. In my experience, this has yielded outstanding results.
I did it and it helped a bit, but doesn't solve the problem, and don't last long.
Pretty strange that I cannot force the fan to run at the highest speed.
> - Use a scaling governor to prevent the cpu from scaling to it's highest frequency
I may try that.

CPU Fan Speed: How to Adjust?

Hello,
My 975X has what I believe is an issue with the SATA controller, which prevented reliable SATA (hard drive) operation. I went to the local Fry's and replaced it with an ASUS P5Q-Deluxe. One thing noticed is that ASUS has a software utility (AI Suite) to control CPU fan speed. On my 975X, the CPU fan ran "full out". When I looked I didn't see a utility to reduce fan speed: Fuzzy Logic and Corecell didn't seem to adjust the fan speed, but could monitor it. Was there a utility to the control the CPU fan speed that I overlooked? If so..too bad..I could've had quieter operation. If not, then I presume MSI motherboards now have a utility to adjust the fan speed so that it scales with CPU temperature, and thus reducing noise? I'd like to know as I'm sure I will buy another MSI motherboard at somepoint. Thx.
Scott

You replaced it? Or do you still have one?
I still have it, but the SATA controller needs to be repaired; new disks, cables, OS installs, and power supply failed to fix the problem so has to be MB. While I can RMA the board, it is about 3 yrs old so MSI wants $35; not sure it is worth it. Comments?
Generally I've been happy with MSI as I've used their boards for 6+ yrs, but I also really like my ASUS boards.

CPU heats up on file copy/backup and fan speed does not increase

Hi Friends,
I have been having issues with fan in my Dell Studio 1555. It has an ATI Radeon card and I had installed the proprietary catalyst driver as the open source driver is too noisy.
Recently, I noticed that on accessing my hard disk and copy files or running backup (luckybackup), the temperature shoots up from around 60 deg C (just using chrome) to 100 deg C when it would shut down itself. However, it seems like the fan speed does not increase with the increase in temperature to help it cool down.
I tried to get the fan speed details with "lm-sensors" but it would not show the fan speed. Here is the output of sensors:
[user@domain]$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +60.0°C (crit = +100.0°C)
temp2: +59.0°C (crit = +100.0°C)
temp3: +66.0°C (crit = +100.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +58.0°C (high = +105.0°C, crit = +105.0°C)
Core 1: +58.0°C (high = +105.0°C, crit = +105.0°C)
Following the Arch wiki, I added acpi_enforce_resources=lax to kernel parameters but it did not help as well.
Here is the main problem:
1. CPU temperature shoots on accessing hard drive but fan speed does not increase - Any guide/direction to investigate would be really helpful.
2. Sensors does not show the fan speed. Read about i8kutils, but couldn't figure out how to get it working with systemd. Any indicators here?

The fan was bad. I had to replace the fan. However, I have not been able to figure out how to see fan speed in sensors.

Is there a way control fan speed in ubuntu linux to replace hp coolsense?

My computer is prone to over-heating when I'm using Ubuntu and so I'm trying to control the fan speeds. I've researched a little and I'm blocked on how to control fan speed and then installed `lm-sensors`and `fan control`.
I'm now trying to configure lm-sensors to no avail. In terminal I typed `sudo sensors-detect` and answer YES to all YES/no questions. Installed modules with` sudo /etc/init.d/kmod start`.
Now when I typed `sudo pwmconfig`
I get this output
/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed
The way I tried to fixed this is to edit /etc/default/grub to add `acpi_enforce_resources=lax` to the `GRUB_CMDLINE_LINUX_DEFAULT` and then perform a grub update. I'm still having the same issue.
Could it be that my fans are PWM 3-pin where fan speed is controlled by voltage?
This is the output of the `sensors` command.
acpitz-virtual-0
Adapter: Virtual device
temp1: +79.0°C
coretemp-isa-0000
Adapter: ISA adapter
Physical id 0: +79.0°C (high = +84.0°C, crit = +100.0°C)
Core 0: +78.0°C (high = +84.0°C, crit = +100.0°C)
Core 1: +75.0°C (high = +84.0°C, crit = +100.0°C)

Core 3: +74.0°C (high = +84.0°C, crit = +100.0°C)
Can anyone help me? Thanks.

Changing Fan Speed On iMac via Windows?

Well I've been browsing a lot about how to change fan speed on iMac from windows. I use windows primarily for development and sometimes my computer can get pretty hot and my room can get really hot because of it. So if anyone could tell me how to do it, it would be extremely helpful. It would even be ok if it was low level assembly code. I just want to change the fan speed on windows and I can't find a program to do it. Thanks in advance.
Matt

Oh it's fine! I kind of wasn't extremely helpful because I have seen a lot of previous posts with not much results (they were a few years old though). Yea the only reason I do use windows is because of .Net framework development :\. I would like to switch to all java but I like XNA and Visual Studio. Mono ***** so I'm just waiting for something good. Anyways thanks for the help. And if any low level mac programmer see's this, please tell me how you could go about this!
I'm sure if someone had disassembled OS X they could figure out how to do it. (Not promoting this because I'm pretty sure it's illegal).

How to reduce cpu fan speed just by hardware?

Hi,
I have a K8N Neo4-F, AMD3200+ and "arctic cooling freezer 64 pro" as cpu fan. The rpm range of this fan is from 300 to 2200. I use "cool n' quiet" and "Smart CPU Fan Target with 40°C" as bios setting. When the cpu is idle ( ... just doing some typing or so on ...) it has a temperature of 32°C and the fan has ~950 RPM.
I think the fan speed is to high for this cpu load (< 5% and 1000Mhz CPU Clock). My expectation in this szenario is to have the cpu fan speed near the lower bound (300 rpm), but I don't know how to manage this (with just bios settings) ... any hints?
Thanks a lot ...

My point was you did what D.O.T. is supposed to do without using it.
Of course it's point is to auto-overclock the system to whichever degree it's set at. The problems come in because a lot of the settings it uses aren't always compatable with a lot hardware combinations. That's why it's best to come up with your own OC settings that are stable with your parts.
It's just like how the Nvidia/ATI speedup option seems like a good idea, but works poorly in practice.
Both are more useful to the marketing dept. in having more "why tech" features available to print on the outside of the retail box than they are to the end user.
