A8Js, do you hear what i hear ?

Here is something that has been bothering me for hours now. Its not the fan noise, no, but its some kind of high frequency noise that seems to be coming out of the notebook. please tell me its not a defective unit again. You can help me if you guys would press your ear onto the laptop where the Nvidia, Centrino and Windows logo are located and tell me if you hear some kind of operation noise that sounds like a "fridge" and from far arms reach away like a lower tone beeping. My ears are very sensitive and the frequency seems to be reflected by the wall so it bothers me a little. Its not very loud but it would help if you guys just could check it out and tell me if its standard.
Thanks so much!

 

no sound here.

 

No

I only hear the gpu fan when ive been playing games

thats about 6 inches toward the screen on the side.

 

mine has no sound. absolutely quiet and low heat as well( probably bcuz i seldom play hi-performance games) mayb u shld check with your friends whether they hear the same thing as u. if not, you shld go check with doctors. if they do hear the same thing, u shld check with the service center. So far they are quite efficient in attending to my case. by the way, the region where the window logo sticker is is where you put your battery right? is there a problem with you battery then?

 

I think someone had posted previously that their asus notebook was emitting a high-pitched whine that was actually coming from their wireless card when it was on. Not 100% sure if it was an a8j or even an asus... might want to scour the forums.

 

im having the same problem too..

im going to the ASUS warranty place tomorrow to see whats up

they say it could be the CPU fan
but im not sure where the CPU is located

it actually DOES sound alike a fridge..
my A8JS wsnt this loud out of the box...=(
what happend

 

thanks for trying to fat but I am convinced that this has to be standard, once again you really have to PRESS your ear against that Sport to really hear it. can you please try this for me? and NO my ears are okay thanks

 

Have you tried changing every variable you can? What if you are on batteries? AC? What if th wireless if on? Off? What about your CD drive, is something in it? What about before you are in Windows? What if you leave your computer sit for a while so the hard drive spins down? What about when it is in standby? I would try changing or checking everything that you can before you are certain something is wrong.

 

I suspect it's the electrical interference sound that was reported on several models starting a long time ago on this forum. I have it when on battery on my V6J. I've learned to live with it, there's not much you can do.

 

i see, apparently it must be some kind of electrical interference, can somebody actually put his ear on that spot just to see if it is with all models? thanks

 

you should be able to hear all kinds of noise coming from your notebook. Harddrive noise, voltage conversion, ac adapter noise and any number of noises that are generated by the electric process. I am not an electrcian by any means but hearing noise from your laptop is pretty normal. Sensetive or not I personally would not warrant an rma for what you described. Use your laptop and worry about warranty when you actually need it. If you really cant stand it i doubt that your laptop is unique. I hear the noise too.......in every laptop. You have to stop listening for noises then your laptop works a whole lot better. Thats my take on it and being picky....sorry

 

I had a desktop that did this whenever I scrolled the mouse. After repeated teardowns it eventually went away, but I was never able to pinpoint the issue (one day it just stopped).

My Z33 makes a noise sometimes on battery, and another noise when the CPU is running at stock voltage at full load (aka - never - since I always run undervolted). Honestly that is about the only nitpick that I have about it, which says a whole lot about the model - I'm a very picky person.

I wouldn't worry to much about it unless you are very sensitive to that frequency. It's really just an expression of your notebooks individuality

 

Same with my m5n and similarly with the majority of notebooks i come across which happen to be most asus

 

I found out where the noise is generated. I ruled the HDD out, the noise was still present after removing it. However, if i start the machine there is a period of complete silence ( 1 minute) where the disturbing sound is not there. Once the CPU fan kicks in the noise comes up. It does not come from the CPU fan on the right hand side but from somewhere underneath the plam rest on the right side where the stickers are located. I guess i have to drive to the dealer tomorrow. Problem is, its a 45 min drive and I could spare me the drive if someone would be so kind to really check out the noise by restarting the machine and comparing fan on/off (press your ear against the plam rest) and describing to me how the noise sounds. What i am looking for is a sound that is similar to the sound generated by electric current. If you listen close enough you can also hear it from further away aswell. If this is the case, then i am just over doing it and i should calm down and ignore the noise.
Thanks

 

exxi, the thing is that a lot of laptops either do or don't exhibit electronic noises like that, even within the same model line. A lot of the time I think it is just based on the unique configuration of the individual components in the unit. Some have it, some don't. It's just chance.

I personally don't consider it a defect, just a fact with such compact electronics. If your system is stable and you don't have any other problems, I wouldn't worry about it.

Hopefully an A8Js owner will comment for you

Of course you are entitled to take it up with your reseller, and I encourage you to do so if it bothers you, but don't be surprised if they tell you that it just happens with some units and isn't something that can be easily fixed.

For instance, noises have been reported relating to a lot of Core 2 Duos changing CPU sleep states - its possible that the software that controls this is ramping up at the same time the fan is, so it's just normal CPU noise....

 

Jumper, thanks for the great posts. In my case i think that the CUP or GPU fan is causing this noise. the problem is that this noise is somehow morphed into a extremely annoying headache causing irregular frequency.

 

hey exxi

i guess im the only other person that finds the sound annoying too =S

well anyways,
i went to the ASUS warranty centre today and had a long 45 minute argument with the dude
in the end, he replaced the CPU fan

this is what happend:

basically he installed ASUS probe, and it said my CPU fan speed was at 3200rpm.
he then showed me HIS laptop (some other model, not sure wht it was) and ASUS probe said 2900rpm

the problem i had was that my CPU temperature was at 35 degrees, and the fan was running at 3200 rpm.
HIS laptop's CPU was at 45 degrees, and the fan was running at 2900rpm.

i didnt understand how my COOLER cpu temp needed the fan up that high

he didnt understand either..which is why he replaced my CPU fan

after replacing it, he realized ASUS probe didnt support Core2duos, so the readings were "inaccurate" as he put.

but i tried the new fan, and when in "battery saving" mode, the CPU fan would say "off" when idle. kinda what i wanted and expected of this laptop when idle.

too bad after using it for the day, whenever something CPU intesive is run, the CPU fan will kick up to 3200rpm and stay there. forever.

this is the part i dont understand
i discussed with my friends and they said the CPU fan should power down when the CPU temp is at a lower level...which makes sense

the problem im having with my A8Js is when the CPU fan powers up, it STAYS up!
and now my fan is again running nice and loud for me

does ANYONE have any idea how to prevent this?
im using Notebook hardware control and the ASUs probe

speedfan doenst tell me anyting

i just want my CPU fan to powerdown when it should (idleing, or small internet browsing), nothing intensive

im kinda angry since i paid almost $2200 for this laptop.
my friend's HP is perfectly silent compared to my ASUS. =(

HELP!

 

That's not uncommon thing in laptops and it usually gets fixed via new BIOS.

You are right, fan should power down when not needed.

 

Man I used to think my A8JS was completely silent but after reading this thread I hear all the noises now... darn psychological effects. Its okay I still love it so.

 

The fan does power down when not needed. It's just that it's needed above 35-36 deg C, for most if not all Core Duos. (At least from what I've read on this forum, people would complain about Core Duo fans being "always on")

Probably the guy's laptop (for which the fan was running lower at higher temp) was a Pentium M. Different types of CPU have different temperature profiles and tolerances. Quoting myself and someone else a longer time ago, if the engineers at ASUS decided that your notebook has to have the fan ON at above 36 degrees, then your notebook has to have the fan ON at above 36 degrees. Don't mess with speedfan or stuff like that, you may harm or shorten the life of the CPU.

Might this be a bug due to the installation of the new fan? A simple piece of hardware with no logic in it shouldn't behave differently when controlled by the same BIOS.

 

yeah i see what you mean, and i agree 100%.
i really wonder what the lowest CPU temp is before the fan should turno off?
the BIOS really doesnt have much regarding the matter..

if it helps, I upgraded the bios to 207 from the asus website..
but yeah..even if i put it on Battery saving now, the fan will still sit at 3200rpm.
the new fan that ASUS replaced sounds teh same..i dnot think its a hardware issue anymore..more like a software issue

haha , is there any way of contacting ASUS and telling them to fix in the next bios? hahaha

thanks again for all your help guys

 

I think it turns off somewhere btw. 32 and 34 degrees
and starts up again at 36

That's the hysterezis. Which basically means that it's running non stop. Now depending on the NB and fan layout and quality, it will generate more or less noise...

 

If the listen to some posters here and raise the turn on temo for the fan then other people will complain of heat. What is the happy medium.? I think the way the bios is now is perfect. The fan is virtually silent. If you can hear anything your are listening too close. I havent updated the bios on mine but i think they are all the same. i cant hear anything at all. I bet if i took it inot my basement i would hear something.,, Thats the nature of laptops.

 

you cannot say that its perfectly silent. There is a fan noise and you even hear it in a louder environment. I dont care about the fan but about the other noise that sounds a bit like electric current.

 

I can say that. i am sitting next to it now. I am in an office on a corner of a commercial street. Granted its not silent here i can hear cars in the background but its not loud either. I cant hear the a8js period over the bg noise at all.

 

hey geared,

have you used ASUS NB probe before?
just wondering what your fan RPM speed is and CPU temp when idling and such. and also, what your profile under Power4gear was at the time? and if you were plugged inAC power


if its around 3200 rpm when surfing net, word proceessing, or anything non intensive, then ill be perfectly fine knowing the A8js is supposed to be like this

i just want to know if your CPU fans will automatically power down when idling, or if the ASUS probe says "OFF" for CPU fan speed when doing low intensive cpu work, or even nothing at all.

also, does your cpu fan run aroudn 3700rpm when doing something intensive? it ran like that when i was playing Warcraft 3

thanks in advance!

 

Thats just not something i check for. First time i see a laptop i check the fan noise. The one i am working on now is a custom rig with a t7600 and 7200rpm drive. All i did was use the restore disk so the settings are stock out of the box. I have to send this out so i cant play with it without having to wipe the drive again which costs me hours of work. i am not willing to spend hours of work unless there is a mass audience that complains on a certain issue. All feedback thus far shows the a8js is quite and works just right according to the many posters here. Sorry i can only tell you to live with it an use it. If you do have a problem that others can confirm and it is not solved by a windows restoration i would be glad to spend my time on. As i sit here i see no problems with the fan or noise on a fresh rig.

 

I will be going to the dealer where i bought my A8js tomorrow. there i will directly compare my device with other new ones to see if the noise is indeed just factory default. I will tell you guys later about it!!

 

Get back to us. I'm interested in what you find out.

 

Alright, I got a brand new replacement device. I must say, problem solved. But guess what.. now the CPU Fan on the right hand side makes a whining noise that is not a whole lot better than the noise i had with the previous device. I guess i am going to kill myself, this is so annoying. I just want a laptop that does not cause me a headache. it should not be that difficult. When i run 3d mark 06 (CPU test) the fan starts spinning faster and the annoying "subsound" goes away and I can only hear the fan, this is acceptable but once the FAN spins back to normal speed or to medium speed level it starts whining. You can simulate the whining by covering parts of the fan exit with your hand. I wonder if i will ever solve this problem
