How can i get rid of CPU whine?

I get it when i have the computer on high performance, not so much when its on powersaver or balanced. also, should i be able to hear my hard drive working whenever it does anything?

sweet jebus i hope i wont have to return this one too.

 

what did you buy, you hear the whine already? and no you should not be able to hear your hard drive in general usage

 

What kind of whine?

Are you expecting total silent when having it on high performance mode? (i see that it's not the first time you return it)

Some harddrives are louder than others, and some laptops aren't as silent as other, so it all depends on what harddrive it is, how it's mounted and into what notebook.

I can hear my harddrive if it wasn't for the rubber "shoes" that i have mounted, so it's pretty much silent for me.

 

E105 from best buy...its kind of annoying as hell. its not as bad as the other one was though...but i will still probably return it.

its annoying because my problem is the opposite of everyone elses.

 

Try undervolting the CPU. If you really care about noise, get a SSD instead of a HD.

 

Is it an EEEE EEEE EEEE sound?

okay, i get it, i dont expect a completely silent laptop anymore. heres what irks me:

mine is bad w/ ac on, its not constant (which almost makes it more annoying), its worth with performance mode ON, not off (which is opposite of everyone else), and its still there on balanced, and almost still there on power saver.

 

Yes, when you say your laptop has a noise most people go 'Yeah, it's a laptop - it has fans/drives get over it'

However, did you read that thread? If it's the same sound it is about a certain power saving mode the CPU is in and isn't about laptop fans/hard drives.

Does it go away when you turn on bluetooth? (Doing so prevents the laptop from entering the power saving mode)

 

oh, i dont care about the harddrive so much, i was curious about the high pitched noise more. i have to figure out how to enable bluetooth. i know its not a problem with the fans...im not that naive i will look into some of those options more. it seems that its actually a bit better now, and i have no idea why. maybe because i disabled toshiba power saver or whatever in msconfig? although i enabled it again, but havent restarted yet.

 

ive seen a similar thread in another forum. the whine was from the basic unibody macbook line. I have one but dont hear anything like others have posted.

 

its weird, this one is quieter than the other one, and i still think my sisters is quieter than this...ive got no idea whats up though.

 

Not all CPU are created equal, undervoling it can help, but you may just have to return the unit for another one.

Also "electronic whine" is something not everybody hears the same, it may be loud and clear for you and nobody else can hear it.

 

The whine is generated from low quality electrical components, which are not shielded properly. Their are ways to stop the whine.
1) reduce thermal load, with a more power efficient cpu, or undervolt
2) a more drastic way. Cover your entire motherboard with hot glue. It works

The cpu does not cause the whine, the cpu causes stress on mosfets, microcontrollers, capacitors and so forth, which make the whining noise you hear.

is it safe to undervolt? CAN i undervolt?

 

yes its safe to undervolt and yes you can undervolt

theres a guide on it on the forums

 

just a question...why arent they all undervolted from the beginning?

 

Because every chip is unique and the manufacturer doesn't have time to test each individual processor for what the minimum voltage it can do stable.

For example, those notebooks you have had, each one is unique, one doesn't sound as much as the other, because they are all unique even though it's the exact same hardware spec.

All of one CPU model for ex. doesn't have the same VID voltage's. One T7600 can have 1.2volts at 2.33Ghz while the other T7600 can have 1.35volts at 2.33Ghz and so on.

 

, beat to it: All CPUs aren't created equal (even ones of the same spec). So they all have slightly different voltage tolerances, so they have a safe voltage level where most (if not all) of the CPUs they produce will work without a problem they also include a little bit of a buffer in those calculations. If intel (or AMD) where to custom test each CPU for it's own voltage tolerance then it would drastically increase their cost.

 

ill try undervolting. i think the whine on this one does not sound like the one on the other...that was really bad, this isnt as bad. it almost sounds like its also the hard drive, but i dunno. you guys think i will be able to undervolt it at all or will it become unstable?

also, bluetooth doesnt really do anything.

 

jease, it seemed fine last night....now no matter what mode i have it on it makes a whine

 

At least in desktop motherboards it's the coils that whine because their potting isn't good enough to keep them from vibrating at the frequency of the voltage going through them. A dab of super glue in them usually shuts them up. Don't know if a laptop has them or not, but if it does that'd be the slightly less extreme way to silence it.

 

not gonna open the computer up is it possible id ever get a laptop without this noise?

 

is it possible that the whine is coming from the HDD? i feel like when i hear the activity in the hdd the sound also goes away.

 

question...i disabled a feature called toshiba power saver and the computer is now way quieter, at least compared to what it was... is up with that?

 

It might have been your core 2 duo processor as I think we tried to explain to you in the other thread

core 2 duos all whine when they switch between power settings (and try to save you battery life)

 

yeah, but nothing else that was said worked. and i just took a complete guess by doing this. its much better, but its still not perfect. maybe toshiba power saver was overriding whatever i was doing? i dont know...im still looking into other options as well though.

id like to undervolt, but i have a p8400 and i would lose 100mhz.

 

what's 5% performance loss for a possibly noiseless notebook that sucks up much less power?

you have the choise

 

I did managed to solve my CPU whine as it happened to my Dell Inspiron 1720. I had to use RM Clock and force the CPU to disable going into C4 mode. It was gone since then.

 

thanks for the tips, ill check those out too. i feel like its less bad on softer surfaces too lol

 

is there ANYWAY to disable the sleep state if rmclock doesnt support my chipset? the noise stops if i scroll up and down really fast, which is indicative of either the processor or hdd having this high pitched sound.

its really annoying because even though my processor is on 100%/100% min/max, there is a power feature that cant be turned off which reduces the speed to 1.6ghz or something, and i cant disable it!

ahh please help!

 

Big Mike... how exactly to cover the motherboard with hot glue on an XPS M1330?
Cover the whole MB, or just the area where the whine generates?
any info will be appreciated.. i am going nuts with the whine.

My video card fried 8 weeks ago, and Dell took it and replaced the MB. I guess I got an MB with the whine. it is A04.

 

Just the inductors, you can put a couple dabs of super glue on them usually.

That's what they normally look like in a laptop, they'll be small. I can't promise you that will fix it but it does in most desktops.
