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.

I've read that if I installed OSX 10.4 then the fan would run quieter.
Is this the case?
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.

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.

Brand New HP 110-230ea Suspiciously Loud Fan

Hi,
Recently purchased a new desktop PC, HP 110-230ea to be more specific. SPECS
The fans since day 1 are constantly very loud even when in an idle state, the noise increases when attempting to do anything such as browsing, watching video etc.
I checked the bios and it shows the speed of the fans to be around 1300'ish rpm but no options to change it.
Is this normal? Is there anything I can do to make the fans slow down?
I dont want to open the PC up as it would void the warranty.
If anybody can help it would be much appretiated.
Thanks in advance.

Very loud fan upon starting imac. Does anyone know how to fix?

My iMac has a VERY LOUD fan that turns on during start up and does not stoop. I tried to shut down and start up again. I also tried to unplug the machine overnight. Still happening.
Anyone have a solution?

This is a part of the larger MacBook Pro connectivity issue. There are several related threads dealing with the MBP's networking problems. If your unit is suffering from this type of difficulty, good luck ... (or a long ethernet cable)
(PS Everybody please make noise on this one so apple comes up with a solution.)

Old and new battery both ~2 hour life, recently very loud fan

1)
My macbook pro, which was purchased April 2006, had suddenly dropped its battery life from about ~4 hours to ~2 in January. I noticed this because I traveled back home by plane with a 4 hour battery life for winter, and within weeks the life had dropped to ~2.
I already reset the system (i.e., remove battery, hold down start for 5 seconds, etc) with no avail. This was with the old battery. The apple store tried the same thing, was stumped, and decided to just give me a new battery.
The older battery was the replacement for the 'dud' my macbook pro was originally given. This new battery should be perfectly fine, but the battery life is still ~2 hours. I tried the system reset with this battery--which didn't work. I have also reduced the battery life to just about zero then charged it again--which didn't work.
Could there possibly be something wrong with the hardware? What can I do to fix it, what is the best course of action to fix this one problem?
2)
Just a few days ago a fan in the top left corner has begun to behave strangely. It has become very loud and seemingly inconsistent even with low CPU usage. By inconsistent I mean it sounds as if it has become loose or it won't maintain a constant speed. The best description for the sound would be 'boiling water.' What could be the cause for this and how can I go about fixing this problem?
Any input is greatly appreciated!
MacBook Pro Mac OS X (10.4.8) Purchased April 2006

1)
Have you checked your battery's serial number against the MBP battery exchange program? I did this out of curiousity with mine and it turned that mine was one of the faulty ones! So Apple sent me a new one and I sent the duff one back. It was still fairly new at the time so it still held a good charge.
2)
I had the fan thing but mine was on the right hand side. Your BEST bet...(what I did) open up quicktime and RECORD the noise several times at different operating conditions and save the files.
send your machine to a service centre and ask for an email address to send the files to so the technician can hear what you hear. I recorded it behaving normally as well so they could hear the difference.
The 1st time mine went in it behaved itself for them so they had to give it back to me, that's when I recorded the noises! I emailed the files before I sent my MBP back again, they took one listen and said they'd order the fans, BEFORE I sent it in. They called me to say that the fans were in so in it went for the replacement.
Hope it helps - mine sounded like it was going to explode and rip apart the inside! I can email you the files if you like?

Macbook has a very loud noise

When I turn on my Macbook Pro it has a very loud whirring noise. The noise continues for the whole time the macbook is turned on. Sometimes it becomes a little quieter but always is so loud my kids complain about it. The macbook is 5 years old but had a new graphics card/chip 2 years ago. The noise started about 2 weeks ago.
I took it to a genius at mac to check if the hard disc was failing and he couldnt diagnose any issue. Thought it might be the fans needed cleaning out.
Anyone got any ideas?
(I am constantly backing up in case the disc is about to fail)
Thanks

Yes, very likely, Ive seen endless clogged laptop and notebook fans ,......a lot of them were horrific
Dust and fuzz residue caked onto the internal fan
Dust bunnies and Fluffy’s fur
Your Macbook’s cooling system, including fan and rear vents pull cool air in from the back and (in the case of the Macbook pro) also from the left ports bringing this air around the processor, GPU, and heat sync and blow it out the back, as such your Macbook acts like a little vacuum cleaner of the air around you. If you use your notebook in a dusty area or around a lot of pet fur, this can quickly, even under seemingly ideal clean rooms, accumulate inside your notebook especially on the fan blades reducing its capacity for cooling and in a worse case scenario seize your fan due to caked on dust on the fan blades. Avoid very dusty areas or places where, over the long term you know fuzz, fur, or even smoke can enter into your Macbook.
Is it making a buzzing or scraping noise?
If you only hear it in a quiet room, that is normal.
noisy fan reasons:
A: you notice it more in a quiet room (the typical case) which is normal, all is AOK
B: fuzz and dust has caked onto the blades causing the fan hub to get off balance and make a buzzing sound.
C: fan rotor is going bad and making a whirring or buzz noise (rare).
D: Fan is spinning up due to excess heat from gaming, heavy graphics (typical, all is OK)
A and D are normal
B and C are not.
Do you use it in a dusty area or where there is a lot of pet fuzz? Laptop fans act like little vacuum cleaners and take in dust etc. from the ambient air around them.
If B and C continue for a long time (B is just a cleaning), they eventually cause the fan to either seize and/or die.
Good news, if that happens, and out of warranty, fan is a very cheap fix.
Bad news, if you let the fan die and continue to run same, you can overheat your unit and cause unwanted damage.

Very loud fan noise

This has probably been dealt with, I have a 2007 intel iMac. It's been running fine but this week the fan has become very loud. Any ideas?

This can probably be reset by doing a SMC reset. Here is what to do on your iMac:
• Shut down the computer.
• Unplug the computer's power cord
• Press and hold the power button for 5 seconds.
• Release the power button.
• Attach the computers power cable.
• Press the power button to turn on the computer.
• Report back results to us.

G4 not starting up, black screen, noisy fan, chimes OK then nothing, after a few mins very loud fan!

Anyone else had this? On start up chimes as normal but screen refuses to come on. Have swapped monitors and same happens on the newer one. G4 was making noises before last week with very loud fan cutting in from time to time. Got lots of work on that computer! Typical, not all backed up! Is it the logic board? How much does that cost to sort out?
Thanks for your help

Hello, it's going to be tough to find anybody to work on G4s these days, Apple doesn't.
Have you blown the dust out lately?
Does the Video card have a fan on it? Does the fan spin freely?
If worse comes to worse, you can pull the drives & get the info off of them with one of something like these...

What is causing the very Loud Fan noise everytime I use the computer? What is causing the Heat as well? Please help

Please Help!
My computer has been making very LOUD fan noises. I know this cant be normal. How can I fix this issue?
This has been going on for a while now. As soon as I turn on the computer....the noise starts.

Go check out Activity Monitor on your Mac. It will show you which programs are running, and how heavy their use of your CPU is.
When mine does this, for some reason, I have a bunch of "Managed Clients" running at once. I use Act. Mon. to shut them down, and my Mac runs normally.

Brand new Itouch has totally stopped working...??? is it the battery or is there a freeze/lock button that was activated?

Brand new Itouch has just stopped working.....no response...battery seemed to be fully charged and then my daughter hit the button to shut the screen off..now no response whatsoever.....???

Try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't help, try a Restore. From iTunes, select the iPad and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad.
There's more but let's take it in small bites.
Also, read this.
There have been some problems accessing pages on the Apple web site. If the hyperlink gives you a "We're sorry" message, try again.

My brand new iPad has flickering lines across the centre of the screen. It has just been taken out of it's box! Has anyone experienced this? Any ideas or simply take back to store?

This shouldn't happen. Take it back since it's new.

The fan on my 24 inch imac has become very loud

The fan started to get really loud. The finder crashes every once and a while and I get the message that tells me to hold the start button till the compuer shuts off, then restart

For the crashing/need to restart problem you may want to post the log here to see if anyone can suggest what the likely cause is. It sounds like you are getting Kernel Panics. You should be able to locate the panic report as described here: http://support.apple.com/kb/ht2546
For the loud fans, you could try an SMC reset, it might help, although it's possible there may be some connection between the events:

Satellite Radius P55W has an annoyingly loud fan!?!?!

I’ve had the Toshiba Satellite Radius P55W B5318 (SSD version) for less than a week and love its performance, its very fast, light and the folding screen is awesome. I discovered that the wi-fi on it is inferior, but that’s still acceptable for me, as is the small SDD size (256 GB). What I didn’t expect is the hardware design flaw in these machines, that being the fan. It turns on and off quite frequently at random times, is loud, and the worst part is it may turn on for 45 seconds and then off and it will make a sputtering noise at both ends. Its very distracting and annoying and is a deal breaker so I have to call this laptop a fail and bring it back to Best Buy and get a Lenovo Yoga and leave a bunch of reviews every where to warn people about this laptop. It’s a shame because I really want to keep it and even looked to see if there was any software that will either turn off the fan or slow it down, but there doesn’t exist any for this computer (Speedfan doesn’t support this motherboard apparently).And I cannot get into the BIOS either to adjust the fan’s power function so I don’t really have a recourse. Toshiba, why did you have to include this annoying fan and then not give us the option to control/turn it off? Do any of you find that the fan turns on a lot to the point of being annoying? Audio90

Hello I just bought the Toshiba Satellite Radius P55W with an i7 processor today. There are many things about it that I liked, which is why I bought it.. bought I did notice right away, that the fan does intermittently turn on and off, even when I am not doing anything, or running any programs. It's funny, because I returned a brand new Dell, and got this Toshiba, exactly because the other brand new laptop was doing the same thing! The noise of the fan is not that loud. But I could see it getting bothersome. Plus, my concern is, why is it doing it? And what happens when I begin running Photoshop and many other programs at the same time? Anyway, to anyone with the same or simiar issue, try doing this... the USB port on the left side, right next to the AC adapter plug-in... use it for either a wireless mouse or wireless keyboard. I plugged in a wireless mouse receiver into that port, and as strange as it may sound... the fan problem has gone away for now. I have a couple technical theories as to why this would make a difference.. but I won't share my guesses.. until I know for sure this is a workaround. I would love to hear from anyone who is having a similar fan issue. Except for this problem, I really love this laptop so far. And if possible, don't want to return it, and look for another one with similar specs and performance levels. LaptopFiend (J.M.)

Sent a brand new U500-ST6322 to Depot but returned with same problem + hard disk re-imaging

I bought this Satellite about 4 months ago and noticed the fan was very noisy (posted a msg on this forum about it). I called Toshiba Technical Support who said this computer had been having fan issues so they asked me to send it to the Depot, which I did. The depot worked on it and returned it with the following note:
"Replaced fan.Hard drive failed test with multiple bad sectors. Replaced defective hard drive. Re-imaged with default software. Set DMI/Updated Bios/Set BOOT defaults. Blew out heatsink/fan and unit. Unit was tested and passed all tests".
So obviously the guys worked on it, only the noise is still the same. The computer basically makes one think there is a vacuum cleaner working not too far in the background. So I am not really sure if Toshiba and I thought there was the same thing wrong with the fan. And I'm not sure what to do next. The fan noise is really distracting and you'd think a brand new machine would be a little quieter. My 6-yr old Dell is quieter.
About the HD re-imaging... I had backed-up my stuff before I sent it to the Depot, so that turned out to have been useful. When they say they re-imaged the HD, does it mean they re-formatted it in some way but kept the same unit? Would there be a way for me to get the stuff from my "old" HD back? There're no important documents, but just thinking about all the programs I need to install again makes me wonder if I could somehow recover the old hard drive. Also, I see a lot of posts with people having sent their computers in and having had the same thing done. Is it normal for a relatively new computer to have issues with the HD? By the way, when I worked with the computer I had no HD issues, at least nothing I could tell.
Thanks for any advice!

from what you put that they did to your machine they replaced the hdd and used the recovery media to reimage the drive back to factory. hdd and other hardware failures either happen very early or very late in their lives. so it is not uncommon to have a hdd that fails right out of the gate but it is much more common for them to fail later. as for getting your old hdd back i wouldnt count on it. it has probably already been sent away to be recycled.
you may not have had any problems at all with the hdd but from what you wrote that toshiba said it had multiple bad sectors. if these bad sectors are too big they will just replace it since those parts of the disc cant be used.
