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

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

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.

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.

Unable to adjust fan speeds after OS X reinstall

Hi all,
I recently had a problem with Mac OS X on my MacBook Pro that eventually led to me reinstalling the OS from scratch. I erased the drive completely and did a clean reinstall using the Mac OS X 10.4.10 discs that came with the MacBook Pro.
Prior to reinstalling the OS, I was able to use the smcFanControl utility to adjust the fan speeds in my MBP as I saw fit. This was a great solution to keep a good balance between noise and temperature. I kept them running at 6000 RPM most of the time because I work on the computer at my desk most of the time. However when I take it to school with me, 6000 RPM is too loud to use comfortably in my classes. I used to be able to lower my fan speed to 4500 RPM, but since reinstalling, running smcFanControl will lock my fan speeds at the max (6000 RPM) and not allow me to lower them. Attempting to enter values manually tells me that I am attempting to lower the fan speeds below the minimum allowed value, but the fans are supposed to be able to range between 2000 RPM and 6000 RPM.
I'm not sure why an OS reinstall would break settings like these, but it appears that it has. Does anyone have any idea how I can reset the range of fan speeds back to what they're supposed to be?
Thanks very much!

Thanks for the reply. Sorry it took so long for me to get back to you but I finally gave this a try and it did not work.
I am currently using the Fan Control application you linked to (as I have been even before I came here) but the variables in that program don't allow me great enough control over the fan speeds. It is temperature-based, which I like, but the minimum and maximum values generally keep the fan speeds too low and the machine still too hot. I am using it temporarily but I much prefer smcFanControl because it allows me to set the fan speeds directly.

Minimum fan speed on N650Ti PE 1GD5/OC

Hi all,
is there any way to lower fan speed below 30% (around 1100 RPM) on N650Ti PE 1GD5/OC?
MSI Afterburner doesn't allow to setup fan speed under 30% which is IMHO really to high for idle state (GPU temperature is around 28C using that minimum fan speed).
Thanks in advance!

There is no way to go below 30% by software. That would require modding the vbios.

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.

What are the default fan speeds of a MBP Retina 15'?

My settings got a little out of control, and I don't really know what the default values were, so what kind of fan speed does your MBP have in idle conditions?
Thanks.

2000 rpm is the base line that the fans run. They can ramp up to 6000 under a heavy load.
smcFanControl does not let you set a minimum speed to a value below Apple's defaults.

Yosemite default fan speed

I'm using Macbook Pro 13" mid-2012 MD101, Yosemite. My default fan speed in smcFanControl now is 4000 rpm. It's just 2000 rpm in Maverick and older version of OS X. Is it OK? Surfing web with fan speed at 4000 rpm is not comfortable at all. It's too much noise

Why are you using a hack to override the designed performance?
Uninstall the hack and maybe it will perform better.

Changing the default fan speeds

I have a MSI GTX 760 and I would like to change the default fan speeds. I can do this in MSI Afterburner, but this is a multi user pc and I want the fan speed to be for every user?

Hmm guess best answer is, Just dont get a msi display card. If there not going to fix a problems with fan speed's.
And MSI gaming app in OC mode makes the fan go no faster than 35%, click normal mode and go's higher.
Just use Gpu-z run test and watch the temp increase. 1 of the ways i have tested.
I feel quite let down as this is not the first time I have reported this and asked for help.
This thread just seems to be for UEFI bios.

Mac pro 3,1 default fan speed?

Hey guys, ive been messing around with SMC fan Controller over the years, and have increased minimum fan speeds due to hotter ambient room temps, or simply because i was running extended cpu intensive activities. Good to take precaution since the 3,1s are known for increasing fan speed after things have already gotten too hot. This can lead to overheating. At some point within the SMC fan Controller app, i changed the "default" fan choice higher instead of creating a new blank custom fan setting before choosing my fan speeds. My problem now is that i dont know what the default settings were. i think one was 500, 600, 600, 800 RPM maybe? No idea.
its is a 8 core 3.2 earl 2008 3,1 Mac Pro Desktop. This has different fans than all other mac pros so this question is 3,1 specific.
I think the four fans are labeled:
Power supply
I/O
CPU
Intake
not entirely sure because i am away from teh computer at the moment.
Thanks

smcFanControl's preferences are located in /Users/<user>/Library/Preferences as com.eidac.smcFanControl2.plist. I believe that if you move that to the desktop and restart, a default plist will be rebuilt for your particular Mac. If that doesn't fix it, you can always put the plist back where it was.
Or, you can simply make smcFanControl not a startup item and then use something like iStatPro to see what the unadjusted fan speeds are because smcFanControl doesn't change the built-in speed defaults, it just overrides them as the lowest fan speeds.

GTX 670 PE OC - need BIOS with reduced dust removal fan speed

Hi,
I'm looking for someone who will be pleased to reduce or stop dust removal fan speed after restart.
Would like to modify latest BIOS with UEFI support.
There was a BIOS which was removed from German MSI site.
I can provide it if necessary.
I'm willing to give some reward for the effort.
Thanks.

Oki, reflash to attached VBIOS.
[boot from bootable USB key to perform the flash]
Flashed and now much quieter at boot.
Many thanks for your help Svet, you guys are amazing.

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.

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..

Intel Imac fan speed? normal ?

Hi guys , im a new mac user and i was wondering i downloaded istat pro
and i noticed a low humming noise when running so i lookd at the fan speed and
the
cpu 1200
harddrive 1600
optical drive 800
im not sure if those are good temps but liek some times after using for a couple hours while just webbrowsing and listening to music i feel the heat coming from like the screen and i touch it and its pretty hot!
an i just use it for webbrowsing and music and downloading like the only third party software i own is utorrent and handbrake..
i posted my computer stats below
are Overview:
Model Name: iMac
Model Identifier: iMac9,1
Processor Name: Intel Core 2 Duo
Processor Speed: 3.06 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 6 MB
Memory: 4 GB
Bus Speed: 1.07 GHz
Boot ROM Version: IM91.008D.B08
SMC Version (system): 1.45f0
ATI Radeon HD 4850:
Chipset Model: ATI Radeon HD 4850
Type: Display
Bus: PCIe
PCIe Lane Width: x16
VRAM (Total): 512 MB

Those look like normal fan speeds for the latest Macs. But you can use software that allows you to create different speed sets for different circumstances.
I use smcFanControl. The first time you start the app it reads your Mac's default fan speeds and creates a default set. But you can create more sets with increased speeds. I live in Monterrey, Mexico with no air conditioning, just fans. It has been around 40°C everyday for weeks on end, and lately hotter. So I have a Hot set where all speeds are ramped up 200 rpms over the default speeds. And I have a Really Hot set where they are all ramped up 200 rpms more over Hot. If I see the temps edging up I usually choose the next set and increase the rpms and that usually brings the temps down to normal. If I see the temps drop down below normal I back off a set on the rpms.
I think Handbrake is probably a bit CPU intensive, so it probably sends your temps up above their normal range when you are just surfing the net.
BTW, rpms are not temps, those are fan speeds. Revolutions per minute.
