Tecra S2 very noisy fan

I have just got my S2 (used to have a S1) but the fan is very noisy. It's so noisy it is even anoying me during working.
I've upgraded the Power Save driver and the Power save software. But een than the noise stays.
The fan also seems to run continuously at full speed. Especially during loading the batteries up again.
In battery mode
In battery mode the fan starts, goes to high speed, stops for a short period, starts, goes to high speed, stops for a shotr while, starts etc. etc This cycle is repeated over and over again. Very anoying.
Why not as with the S1 series where the fan seems to be running constantly but than at low speed so you wont hear it.
On full power mode
The fan is as in battery mode going regular to high and goesback down again to lower speed also with regular periods. Why not leave the fan running at average speed?
And as written above when the battery get's charged the fans keeps running at high noisy speed!!!!!!
Isn't there a possibel hardware update with a fan with less noise? Maybe by other type of fan.
I'm thinking to go back to my S1 again and sell this S2 as it's very anoying while working/studying.

Hi
As far as I know on some units the running fan is normal.
It's also normal that the fan make such a noise.
I know that its possible to run 3rd part tools to let the fan run all the time in slow speed.
I think you can find them in net.
Furthermore you can try to make BIOS update if one available is on Toshiba download site.
You can find all of them on
http://www.toshiba-tro.de/subpage/bios.html
By the way the only way out to change some cooling fan settings you can find in Power Management.
Good luck
Bye

Boot into OS 9 = very noisy fan

It's been years since I booted into OS 9, so I gave it a shot to run a few programs that don't work in classic but did upon booting OS 9.
However, the fan is very noisy. I do have the latest firmware along with a 360w psu.
OS x is very quiet, OS 9 is ready for take off!
Any work around? or do I grab my helmet and pilots license!

Hi-
I do have the latest firmware along with a 360w psu.
This firmware?
http://docs.info.apple.com/article.html?artnum=120171
Or later?
The 4.4.8 was supposed to help with fan noise (not from the PSU, though).
Other than that, though, fan noise in OS 9 is historically a problem; much more so than in OS X.
Heck, Apple even posted a KBase article, telling owners to "expect" noise:

G60-445DX Overheat and very noisy fan

Hi , this is not new my laptop overheats and has noisy fan. My question is how can I get to speak with the support team after my warranty is finished ?

Why you are in this situation is sort of an existential question I cannot answer. You can try calling HP and see if they will make an exception but the few times I have seen that happen the warranty was up by a few weeks at most. We here at this Forum do not work for HP. We can help you fix the laptop by linking you to information, manuals, parts sources, etc. but we cannot make HP do anything. You are really challenging the concept of a limited warranty and I think that issue is not even worth debating. You can also try a simple fix. Hold a paperclip in the fan grille to stop the blades from spinning. Blast in the strongest stream of air you can find. Maybe the fan is just clogged.

T60p Very noisy fan

2613-ETU WXP-SP2 and all Windows Updates plus all System Updates except those recent ones that only exist to handle new ThinkPad models.
My fan is noisy, to the point of rattling, sometimes.
I have 3 years remaining on my 5-year next-day/on-site warranty. If I can get Lenovo to send a fan, should I replace it myself?

It is something that you can replace on your own. But Lenovo Tech Support might not send the fan to you. They don't consider the Fan a Customer Replacable Unit. It won't hurt to ask. But I suggest that you ask for a Tech to replace it for you. They might have parts that they can't ship to you like thermal grease.

Very noisy fans

So i remember reading a few years ago a suspicion of a bug that caused Apple computers every nine (?) days to suddenly experience massive fan activity if left running constantly. This has happened to me a couple of times now, returned home to find fans running very fast and at great volume. Anyone else experiencing this and/or know if it is a recognised problem with a fix? Apart from the obvious one of not leaving the computer without a shut down for such a period...

Do an SMC Reset (System Management Controller: responsible for fans.)

These instructions have recently been modified. Try holding power button in for five seconds while unplugged. I'd try it both ways.
Get iStat Pro and check the temps and fan rpms

Brand new U500 has a very loud fan

I received this brand new U500 (customized on Toshiba.com) about 10 days ago - everything works great (love the back-lit keyboard) - but the fan noise is a little louder than what I'm used to. I had a 6-yr old Dell XPS with a quieter fan than this brand new Toshiba machine. Basically if I'm standing 20-30 feet away from the laptop I can hear the fan, and one can wonder if this comes from a refrigerator or a vacuum cleaner working in the background.
Has anyone had a similar experience - is this fan noise something I should just learn to accept or do you think I should do something before the computer comes out of warranty? I really would hate to have to return a brand new computer, but at the same time I think fan issues only get more numerous when a computer gets older.
Just for info, the machine is Satellite U500-ST6322, CORE 2 DUO P7450 2.1GHZ, 4GB RAM, DVD Slot load.
Thanks a lot.

No, that wouldn't make a difference. eMacs are famous for their very noisy fans.
Some say they were originally intended as turbine impellers for Boeing, but were rejected as too large. So Apple picked them up, and modified them for use in the eMac.
eMacs were made to be workhorses in classrooms and their robust design includes that heavy duty fan, which does impose itself quite loudly.
Some people have installed a means to introduce resistance to the fan circuit to lower the voltage and hence the fan speed, in an attempt to quieten it down.
Whilst this practice seems to work, personally I would be concerned about that causing overheating as during summer things can get very hot here, though perhaps would be less concerned if living in the UK.

Noisy fans on all the time

I have come over from the dark side today (PC to Mac switcher). I got a second hand Mac Pro 2.66 quad with four HDD and 4GB ram and i seem to have very noisy fans. I did find this article
http://www.amug.org/amug-web/html/amug/reviews/articles/intel/fan/
which mentions that extra drives cause more noise due to extra heat and less airflow but this is just silly, they sound like they are on full ALL the time.
I have alread tried resetting the smc_rst button on the logic board but that did nothing. I also tried restarting the machine with command, option, p, and r down before the grey screen on startup and that did nothing.
Is this normal. is it just down to lots of HDDs/RAM or should i be worried?

Mac Pro most likely for "MP" shorthand.
Considering how the drives are placed, can't see that they block air, though they may not get direct ventilation.
FBDIMM memory needs to be kept cool and the top memory Riser and higher density DIMMs do tend to be as much as 10C higher (with 2GB DIMMs running the hotest).
I wonder if you got it with a system already installed? or did a full 'wipe' of the system drive and started fresh. There is a little program most people now use smcFanControl which can force the fans to run at a minimum rpm (though not the PSU fan, either software defect, or the logicboard won't allow forcing it if the sensor doesn't register a higher temp).
SFC would put a little menu item on the menu bar and to acces the program preferences. There would also be a log-in] in user accounts, and a startupitems in the top level Library/Startupitems usually.
Also, look on the Dock for items that can be controlled from there to "open at login" or disabled without having to open any control panels.
If it was me, and I bought a used system, other than direct from Apple Store (Specials, great deals on refurd equip.) I would start over with installing the system.

Noisy fan (or fan-like) sound coming from machine. Thoughts?

My macbook pro is from 2008 to start. I had the computer completely refurbished back in August 2011, though.
However, in the last two days, it has twice produced this impossible-to-miss noisy whirring/rattling sounds that sounds a lot like a very noisy fan. The first time, it last for about 5 seconds just as the computer was starting up after I'd left it closed and off all night (leaning against the wall). The second time, however, the computer had already been on for several hours, always upright, and just for some random reason started making the same noise. This time it lasted for a good 15-20 seconds.
Any thoughts on what could be causing this sudden noisiness? Whatever it is doesn't appear so far to be affecting the actual functions of the computer itself.
Thanks!

HI,
Probably a good idea to run the Apple Hardware Test just in case and make sure you have all your important files backed up to an external source.

My EMAC G4 has a very loud fan.

I recently bought my first apple machine - a used emac -
running OSX 10.5.8
But the fan is LOUD - not noisy - I mean it's sounding like an air-conditioning unit on medium and makes listening to any music uncomfortable.
I've read that if I installed OSX 10.4 then the fan would run quieter.
Is this the case?
Thanks for any help from a new apple user.

The fan in my laptop became very noisy at minimum capacity after ins Win 8.

My laptop - HP Pavilion dv6-6b56er. After installing the Windows 8 the fan in my laptop became very noisy at minimum capacity. As far as I understand this is a common problem. I installed the latest version of HP Support Assistant and HP Support Framework, but there was an error during installation of HP Coolsense "There is a problem with this Windows Installer package. A programm run as part of the setup did not finish as expected. Contact your support personnel or package vendor".
Sry for bad Eng, im using Google Translate.

It looks like this unit has received Windows 8 drivers.
How was the system upgraded to Windows 8? Was it through a clean intall or an in-place upgrade?
Has all Windows 8, including switchable graphics in particular, been installed?
Here is the software page should you need it.
My notebook's fan was operating louder than usual when I upgraded to Windows 8. This turned out to be that swtichable graphics was broken by the upgrade to Windows 8. Effectively, both video cards were running simultaneously resulting in more heat being produced. What resolved it for me was installing getting switchable graphics to work properly. For me, this required a lot of work since my unit was not certified for Windows 8 and would not get any new software for Windows 8. It's an old notebook, so this was expected. However, your system does have a Windows 8 AMD driver for switchable graphics from HP, so I would start by making sure that specific driver is installed.

Why did my iMac fan come on very noisy after 1 hour of use ? I had to turn it off to stop it

Why did my iMac fan come on very noisy after 1 hour of use ? I had to turn it off to stop it

Just updated details - os x 10.8.5 .....
found an answer that could have been problem with CPU and a runaway application (possibly Bin Weevils) which my son was running at the time. I shall check the activity monitor next time to see what percentage cpu is being used..

Fan very noisy

Hi I bought a new Macbook 13" with 2GB RAM and 2.4 Ghz dual Cpu.
I found the fan very noisy and alvays conne4cted.
Can anyone help me What can I do ?

Try resetting the SMC. [http://support.apple.com/kb/ht3964]. The SMC controls the fans. If not, Take it to your nearest Apple Store or Apple Authorized Service Provider. There may be a disconnected sensor in which case the computer would ramp the fan to full to avoid overheating.
