Much better- and question about constant fan noise

i couldn't start anew thread a few minutes ago. I replied to 2 threads, then the startanew thread iconmagically appeard! I am not making it up.
any way- i posted a while back about noise. I thought it may be the hard drive. But definatley it sounds like the fan(s) in my MBP dual core
my MPB was silen when i first bough it. then a few month in it got noisy. Now thw fans are on all the time.
anyone else with a MPB that is just noisy? this *****! macs are almost always quiet. this is annoying acually. and it is non stop! i can't recal a moment when the fns were not winding like tiny air craft jet engines! LOL wel, it's not that funy actually.
the noise does change in pitch on occasion. sort of like they slow down a tiny bit. other wise they just hum away.
I had a G-4 I mac- SILENT! then a dual G-5 tower- it was quest until it roared up on a task, then it roared with power then got quiet again.
but this tiny mpbis just noisy!
Well, i hoope it is the fans, not the HD. It prettty much sounds like fans, and constant.
but considering theroom temp is abou 68 in here, whywould the fans be on? and non stop?
we live in a cold climate, so it's not a 100 weather.
any help with the fans and perhaps a test or a way to turn them down? does my system think the core is hot?
thanks for any help

only about 13% is a peak ap. nothing major, nor a lot of stuff. but nothing consuming 30 40 or more percent or anything. Nothing running except safar in this case, activity monitor.nothingexcessive like 10 aps , whihc i have done in the past as we know the macs can handle it
well, nothing seems out of the ordinary.
I included a pic from that FAN CONTROL AP- well was going to, but not sure how.
any way my stats from it are:
base speed, 1500 rpm (on both actually)
ower threshhold 122F
upper 176F
current temp at that moment was 101F
can someone compare their fans to mine and their temp- i assume it is the cpu core temp.
any way, not sure what is a safe range, nor why my fans are running non-stop.
just noisy? but like i said they do occilate a little ans slow and the hum gets deeper then they go back to normal which is a slightly higher pitch.
as for that iStat pro ap. i opened it and it just made my application dock bar flash then the dock came back. The Istat pro didn't open.
Um- it looks like a widget. I may have taken my widget ap of some time ago. I hve yahoo widgets on. but not sure how to get that istat to work. I can't even recall the name of the apple widget program.
thanksfor help on tracking this noise down-
are any of your guys's fans really noisy? is this common? mine is just non-stop but if my settings are off or if there is areason, then I can adjust it from there. just want to know what the "normal range" or operation of the fans are. but man they are noisy for a mbp. and they WERE QUIET when i first got this laptop.
thanks again

I have used still photos to make a Quick Time movie using FCE. The DVD made using i-DVD looks somewhat grainy and the motion isn’t smooth when played on my TV. Other DVD’s I have made play much better and I am wondering if the problem is my Quick Time movie settings. The Dimensions and size of the problem movie are 1920X1080 and 584 MB respectively, while the movies that play better have Dimensions of 853X480 and are about 1.3 GB in size. Is this the source of my problem and how do I change things for the better.

Are you exporting to QuickTime Movie, or to QuickTime Conversion? For iDVD, you need to export to QuickTime Movie. Exporting to QT Conversion will kill the quality if you are moving the video from FCE to iDVD.
The file size per se makes no difference.
What size (pixel dimensions) are the photos that you put into your 1920x1080 sequence? Also, exactly what are the sequence properties ... is it 1920x1080i60 ... or i50? In North America it should be i60.
853X480 is an odd frame size. Where are you seeing this number? It would appear to be DV-NTSC, which has a frame size of 720x480. Your 1920x1080 frame size would not be DV-NTSC, it would be Apple Intermediate Codec. DV and AIC will look different, for sure.
Also, your quality setting in iDVD can affect the final video. You may want to check that also (in iDVD Preferences > Projects). Set it to Professional Quality if at all possible.

* Buying Vado HD - 1st or 2nd gen? and question about pricing *

Hi.
I want to buy the Vado HD. I'm deliberating between the st and the 2nd gen. Can you help me with that?
Second question, how come the 2nd gen (that supposed to be better and newer) costs less than the st gen?! (99$ for the 2nd gen and 229$ for the st gen).
Thanks,
Adam

CRe: * Buying Vado HD - st or 2nd gen? and question about pricing *# To me the Vado Rev3 seems to be trying to get the same feature set as a digial Camera with HD recording capabilty....except the cameras take better stills. I have the below Canon and the Vado HD Rev.
http://www.amazon.com/Canon-PowerShot-SD780IS2--Stabilized-Black/dp/B00SER47Y
We don't use the vado anymore since the camera is always with us.
Factor into the price of the Canon also purchasing a highspeed 6GB sd card.
if you are really sold on a Vado...look at the comparison here:
http://www.myvado.com/products/comparison.aspx
Note how they reduced the recording time of the new models to only 4gb instead of 8gb.....however, the newer units nati'vely record to MP4 which is a little easier on some software programs than the AVI container.

New hi-res G4: Constant fan noise

Hi,
I just received my brand-new 1.67 GHz PowerBook today, as a replacement for a year-old 1.33GHz PowerBook which was stolen from me.
The old 1.33 used to be silent as a graveyard during normal use. But the new 1.67 issues a constant fan noise. It is not very loud, but very noticable and definitely annoying. It is always present from start-up until shut-down, even if I am not running any applications.
Should I return it to Apple? Or are there any tests/fixes I can try?

I have also got one of the latest PowerBooks and the fan noise is more noticeable than my previous 1.5Ghz model, however I wouldn't have even noticed it if I'd not had a previous model.
There have been some other similar postings on these discussion pages.
One of the criticisms of the previous model was that the underneath of the case could get very hot, I believe the fans run more often to cure this problem and in practice the PowerBook runs a lot cooler. It never gets hot, just a bit warm.
The fans still speed up when doing anything intensive, such as playing some of the high definition trailers I downloaded from the quicktime section of this website. Try it yourself and see if the fan noise increases after a short while.

The 4-row Thai keyboard is so hard to type. 3-row keyboard is much better and more user-friendly. Is apple going to provide the old 3-row to download? Please....

I & a lot of my Thai friends are having a problem with the 4-row Thai keyboard coming with ios6. It is very tough & hard to type. We have more than 90% of typo. Is apple providing rthe old 3-row Thai keyboard to download? Please.....it is much better and more user-friendly.
Well, your reply is much appreciate.
Thanks.

Can't agree more. I have no idea why they changed it. The old three row one was innovative and far easier to use. The vowels were all kept in one bucket button so they were easier to find. Wished people made more of a fuss so that they would add the old keyboard back and allow people the option to choose between the two. I no longer type in Thai as it's seriously too much effort.
Usability FAIL.

Constant Fan Noise from Hard Drive

My power book runs with a constant 'fan' like noise from the hard drive (front left of pd)
My friend has same machine and has No sound,
checked with display models in Apple Store (ear right necxt to pb) - No sound
I have had this low level noise from new.
Anyone else have the same problem.
John

hello there!
When I upgraded to 1.4.0 and I notice that ear piercing noise and it was quite annoying. I called Apple and they advised me to look into the activity monitor. And YES, it ws the anti virus that came with .mac that 1.4.2 for some reason did not like and the process was running for such a long time consuming the resources including of course HD. I removed the anti virus (which at this point was useless) and the machine was just wonderful again.
I think what I may say is that you may want to look for a process (using the activity monitor) which is eating the cpu alive - if you can remove it the better, else try to deal with. Good luck - an OSX convert!

Constant fan noise on macbook pro

Hello, my macbook pro (mid 2010 model, 13 inch, 2.4 ghz intel core duo 2 running Mountain lion) is experiencing constant fan activity at very high speed. The CPU however is only used at 9% of its capabilities top. The problem occured after a freeze in adobe Lightroom, since then, the fan noise start as soon as the computer starts (except if i press some keys before i turn it on for some reason, the noise would come back if i shut down the computer and restart it, or simply close it). I'm dully aware that it is normal that the fan is constantly working, but not usually at such high speed (top speed of the system), I checked all the major solutions offered on the net so far with no success (reset SMC, reset Pram, checked if i had some printer activity on the waiting list, checked the activity monitor for any particular demanding activity or tasks and finally i tried to run an apple harware test to see if some temperature probes are broken on the motherboard, however my computer for some reason is not taken care of...).
I also would like to mentionned that i change the original hard-drive not long ago for a hybrid harddrive (seagate momentus XT), yet the problem did not start after the change.
if you do not think of any solutions, you could maybe tell me if its problematic for my computer's fan to run at full speed..
thank you very much for any help you could provide and sorry for the eventual mistakes in english (its not my first language).

Re: Apple Hardware Test. There was no original install disk, as i downloaded mountain lion. While the connection was established to access to Apple hardware test, the test could not run on my mac, the AHT program said that my machine was not supported.
thank you for your diagnostic, it seemed to be a logical explanation, however, thanks to a monitor program i could check that my processor was running under normal temperatures (35°c to 75°c) so at least the temperature informations seems to be correctly assessed by the sensor.

GT 70 missing graphic card and constant fan noise Issues

Not even sure if this is the correct place to post this thread if not could someone move it to a different section.
So today for some odd reason my laptop decided to freak out on me. I get a bluescreen saying VIDEO_TDR_FAILURE, I have GT70 NVIDIA GTX 675m I was doing a scan on my computer and the lower right hand corner it said Application has been blocked from accessing Graphics hardware. So before it kept saying that over and over again. The computer basically just lagged out and I did a hard shut down to turn it off. I turned it back on and it started up to the BIOS for some unknown reason I didn't press any button so then I go over to Save & Exit and it said do you want to save the changes, I said no and it started up again to the desktop but very slowly.
Then my desktop finally shows up but now I hear what appears to be my video card fan or the fan that turns on when you are overclocking or just when you hit the fan button on the keyboard constantly running. I am freaking again myself because I don't want this laptop to die on me. My NIVIDIA card is no longer even showing up on the taskbar, even when I go to control panel I click on the NIVIDIA control panel and it doesn't even come up. So I try doing a system restore, after it restarts the video card is showing up I do a couple of restarts to get things back in order again. Even the fan is no longer blasting like before which puts me at ease.
I go to watch a YouTube video and then the video freezes then in the lower right hand corner I couldn't see what it was because it faded away something about the video card crashing so then after it crashes my fan starts to go off again and I am freaking out again. I tried to do another system restore but it seems that it's not working any more. Is my video card dying or do I need to install new drivers for it.
How come it's no longer showing up on my device manager? Did it die or something?

It has been acting very strange today. I turned it off last night and went to sleep, woke up a couple of hours later to turn it back on and it went to the desktop very slowly but my GTX 675m card showed up in the display under device manager also the fan was working normally like it usually does and not constantly going. I was sort of shaking my head not understanding how it showed up again.
So I took it into a computer repair place to see what they might make of it. Won't get any word until tomorrow or Monday to see what it might be, strange enough when they booted up the system at the computer place it booted up quickly and he told me that the GeForce Experience thing opened up and all that. But I don't really trust the laptop, I told them I would still like for them to check it to see if my GPU is really dying. They said they will run some tests to see if it's a hardware problem or software problem.
As for buying a new GPU I am not sure i want to pay that much, is there something more cheaper that might be better than 675m? I keep hearing people saying how bad the 675m is and how NVIDIA does not care much for that particular card. Also my 2 year warranty for the laptop just expired in January and I have no idea why this always happens to me once the warranty expires something wrong happens, not sure if it's a coincidence or just bad luck.
Guess I will see what happens when I get the computer back from the repair place, paid $89 dollars just for them to check it which they say is a lot better price than Geek Squad cause they would have me paying $200. Ugh! This crap makes my anxiety go sky high. Hate to lose my laptop, I mean it seems to boot up to the desktop but that stupid cooler fan going full blast is what concerns me.

Question about T400s fan

Hi, I have a question for T400s owners,
Have any of you noticed a "hiccup" in the t400s fan? I can hear the fan (its not a quiet as some people say it is) and it clicks or hiccups kind of in a rhythmic pace every few seconds. I'm wondering if the fan is going bad

Hello Samtoossi,
I have the exact same phenomenon on my brand new T400s (2808/D9G). It sound like there is some sort of strange mechanism to "respin up" the fan every few seconds : the fan speed is not constant at any time in fact, it spins a little down, then there is a little boost, and again and again.
I'm not sure this is an issue, even if I wondered at first... And now knowing I'm not alone...
Did you contact Lenovo for that ?
Thanls
No, I just use TPFanControl to keep the fan off most of the time. I'll wait until something major happens and then include this issue into the mix when I call lenovo. Im kind of hesitant to get anything in this laptop replaced right now. If its the fan that needs to replaced, its not a big deal, but If its a motherboard issue there is no way in I'm going to replace it because there are many reports by other owners of annoying processor whine, unresolved random shutdowns, and melted speakers. I'm pretty happy with the current state of my laptop, thanks to TPFanControl
FYI, this looks very similar to the infamous "pulsing fan" problem that affected many of the earlier IBM Thinkpads. Its due to ACPI polling the fan RPM every few seconds (every 6 sec for my T400s). IBM eventually released a BIOS update which fixed the problem. If you run TPFanControl, you will see that the pulsing is only noticeable under fan speed 2 which constantly changes speed. Fan speeds 1, 3,4,5,6,7 don't have this problem (speed 3 kind of has it, but its no where as annoying). It could be that this is a common problem, but most people just don't hear it because of ambient noise or they're just not bothered by it. Hopefully, a BIOS update in the future fixes this problem.

Is an 'audible' constant fan noise normal?

I have browsed literally hundreds of similar questions and support pages related to this issue but none seem to relate directly to what I am experiencing.
I have very recently began hearing a very noticeable and constant noise from my MBP. It does look like the fan is the culprit but I have none of the symptoms. The fan speeds are always 1998-2000 rpm, temps are always 49-51 degrees, and absolutely no high intensity processes on the CPU ever.
Does anyone know what else might be the cause of this? Dirty fan blades? I am usually in very controlled and clean environments and have almost never used the MBP on any other surface than solid.
Also, could the noise be coming from the HDD? It is way too smooth to be coming from HDD but I am wondering if that is even a possibility.
Any advise or suggestions will be appreciated!
If I am unable to solve this within the next few days, I plan to take it in to Apple.

Well, yeah. I began noticing the sound only after the update.
I took it in to Genius Bar and they said it's working fine and offered to put it in extended diagnostics for 48 hours. Since I use this laptop for work, I'll have to go back there later but at this point as others have pointed out in this thread, I am thinking this is due to dirt buildup.
If I do get around to attempting to clean it, I will post an update on the outcome.

Question about youview fan

Hi guys
I just bought a bt youview box and started using it and noticed that it was getting hot. The box wasn't making any noise really so I looked at the back and noticed the fan wasn't running. So I took it back to the shop a d they gave me a new one get home turn it on and the fan isn't running ? Does the fan only cut in when the box gets really hot ? Or I'm I just really unlucky.
I heard these youview boxes can be noisy but I can't hear anything apart from the hard drive ticking abit.
Any help please

IBook 12" 1.33 Question about the Fan?

I am looking to purchase an apple laptop for class and work. I have a HP laptop now that runs great and is fine, except the underlying problem is windows just plain ***** and I'm tired of all the crap that goes wrong with windows. I have a mac desktop, the new iMac 20" core duo, but am looking to replace this laptop since I may need it for school and work.
My question is geared towards those that use their iBook with light/moderate use...does the fan run constantly and is it loud? I think the most annoying thing about this HP laptop is sitting in class or a meeting and the fan is running and its LOUD! So, if I were typically using microsoft office (i.e. word, excel) or photoshop, would the fan be running a lot?? Thanks for any advice!

Have to politely disagree with this comment... an iBook's fan can be quite loud! It's quite obvious when it's on vs. when it's off!!
And it could run while using Office depending upon
a) air circulation issues
b) background indexing
c) hard drive room
etc.
But having said all that, I don't think this should prevent you from buying an iBook as the fan will rarely come on under normal operating circumstances.
Until recently, after upgrading to the laste OS and security update, and seemingly ONLY when indexing an external hard drive, our iBooks' fans have practically never come on at all.

Question About Northbridge fan

First, my system specs:
Intel Pentium 4 Prescott 2.8GHz HTT w/ 800MHz FSB
Thermaltake Spark 7+ Xaser Edition A1715 CPU Cooler
MSI 865PE Neo2-PFISR motherboard (BIOS ver. 3.8)
2x512MB Kingston PC3200 DDR SDRAM @ 400MHz
Maxtor 6Y120M0 120GB HDD 7200RPM SATA150 8MB cache
Built-by-ATI Radeon 9800 Pro @ XT 128MB DDR 256-bit @ 415/744 (Catalyst 4.12)
Arctic Cooling VGA Silencer Revision 3
Creative SoundBlaster Audigy2 ZS Platinum
Sony DDU1612 40x/16x DVD-ROM
Sony CRX230ED 52x/32x CD-RW
Enermax Noisetaker EG475P 470W PSU(+3.3V = 34A, +5V = 40A, +12V = 33A)
Windows XP Pro SP2
Even though on MSI's website the picture for the PFISR doesn't have a northbridge fan, mine does. So, is there a reason why this thing is so bloody loud? It sounds like a piece of plastic is just barely sticking up into the fans, creating a rattling sound. If I turn my CPU fan speed down to a moderate speed, the NB fan is the loudest thing in my case, and I have five 80mm case fans and two PSU fans going full speed.
Does my motherboard have fan control for this fan? Is it possible to turn the speed down some? What if it I just remove the damned thing altogether? I don't really see the point of having the fan there anyway, since both it and the heatsink are so small that they can't really be moving that much heat. How hot does the northbridge usually get? Is it possible to overclock the northbridge and see any performance gain?

Thanks, that worked perfectly.
And I configured Speedfan to only run the NB fan at 75%, and it is now much quieter.

Much better- and question about constant fan noise
