View Full Version : how quiet are your fans on G75?

how quiet should the fans be on idle?

i ask because i just got a G75 and it's simply AWESOME in every way except there's a clear, sharp, "musical" humming tone from the fans all the time. one minute soft (CPU fan on, always), another minute loud (GPU fan also turns on, every minute). and it's driving me silly lol...can't read, write, think. i'm writing this on an old (quieter) lappy.
possibly unrelated, but there's also a small metal thing rolling around inside (more to the left/CPU side). something loose?

temps seem ok according to hwinfo64:
Idle: CPU 37 C, 2000 rpm constantly / GPU 37 C, cycling between off and 2000 rpm
Heavy load: CPU 68 C, 3000 rpm constantly / GPU 55 C, 2600 rpm constantly

fan filters were ok. rotating the laptop didn't help. didn't find any drivers/BIOS that turns fan off while idle. i don't know what else to try.
so i'm wondering is this normal? what do your laptops sound like? do people have silent fans? what's the noise distribution among ASUS users? (because i thought ASUS was famous for its quietness.) or does everyone have a little meditating guy under the keyboard humming? please help! thanks

I have the G75-vw. The fans are whisper quiet and hardly noticable when playing SWTOR.

I can slightly hear them blowing air but no humming whatsoever.

Mine are silent at idle/web browsing and then ramp up when playing games. Nothing to loud and sound normal.

My G53SX is a little louder. All the ASUS ROG machines since the G73JH have had excellent cooling systems, so you should not hear anything more than a little whirring noise at idle. Gaming is a different story, but that is due to the extra that all the hardware is generating. Those now-noisy fans are why ASUS notebooks don't over-heat while gaming, unlike so many laptops.

My G55vw is so quiet that I was beginning to wonder if my fans were even working...lol. But with the temps as low as they are (around 40c on cpu and gpu at all times) they must be.

The fans on my G74SX are so quiet, I can hear my dog blink when she's in the next room!

Thank you! Thank you! I'll be here all week...

Mine only gets noticible after a period of high cpu usage.

They do. The G-series laptops are so big because of the gigantic heatsinks that they have, which make it easier for the fans to work without needing to be as noisy. My idles temps are in the 40's C and 60's C while gaming.

Feel free to read my thread here, http://rog.asus.com/forum/showthread.php?28993-G75-fan-speed-rpm/page2

And for all you who say your fans is whisper queit, stop it.. your lying, the g75vw is pretty loud, or atleast you hear it good in idle. My cpu is on 2000rpm in idle and gpu goes beetween 2000-2600rpm in idle, depends on what temperature the gpu is at.

So ye it makes some noise, its not whisper queit as some people say. Trolls.

Unless you've been sitting next to my G75 you have absolutely no idea what you're talking about.

G75VX here.. whisper quiet it is... especially compared to other gaming notebooks out there.
even while gaming i hardly notice the fans / the airflow. best notebook i ever had. Big thanks to ASUS!

Let's not flame please! :) It is possible--and very likely--that people have different definitions of quiet. I generally call a lot of things quiet, but then again, that is me. Others I know differ on this. Let's just keep things civil.

well it's great to hear that most people actually got ninja fans. guess a few of us just got unlucky with defect/damage. it happens...

soo anyone got tips for loud fans? like i said i checked temps, filters, drivers, BIOS. didn't notice anything wrong. any idea? or is this a trip back to the workshop (also for that loose part i hear rolling around)

Ive had two g75vw, first one had a faulty keyboard so i changed for a new one, both have same sound on fans, and none were "whisper queit" so no its not defective, just people have different opinions on what "queit" means.. so its not defect.

well they are quiet. If you ever heard fans on an Alienware,well these are almost ninja quiet compared to them.

Saying the fans are whisper quite on my G75 is a understatement, because a whisper is much louder!
The only time I hear much from them are in gaming, video conversion, or any process that's video intensive!

there is no point comparing to other gaming laptops, we are not trying to satisfy ourselves ~ oh nice, alienwere is louder ~ ....

Asus g75 is not a quiet laptop on Idle, if you are always on quiet environment, you will hear that voice all the time, i have same problem, your old notebook does not make this much sound because its system is not as sophisticated. If your pc is at 40C at idle, your laptop has no problem.

I haven't read every post but, seeing as none of the reply's on the first page have mentioned it, the metal thing rolling around inside is most likely the fan filter.

I compared to an Alienware because this is the only gaming laptop besides ASUS one I've tried...I use an older K93 laptop too and this one is actually more quite than G75. If you are interested in actual loudness maybe you could try to find a noise meter. (there is even an android App on the market)...

wow I just put a noise meter on my tablet, so i could see how loud my desktop fans are and it only came up between 2.0-4.0 and i know my g75 is way quieter than that, as my desktop has 7 case fans on it so my CPU/GPU fans wouldn't even be detected. so if this noise meter is actually accurate then the g75 would be whisper quiet.

that was my 1st guess too. so i removed the filters and it's still rolling around inside (and humming). when i put filters back in i noticed there are some projections on the removable panels that keep filters securely in place. so maybe it's a ball bearing or screw.

when you guys say "whisper quiet" do you mean just the sound of air blowing, or also a musical-ish humming tone? cause this G75's air blowing is definitely unnoticeable but there's also a distinctly different hum noise. just wondering if the hum is normal for everyone.

Tomislav

well using noise meter is a bit of a getto solution...(I'm sure it's not correct as a pro nois meter,due to your table/smartphone quality) but it should show differences if you do some kind of a comparision test (like you did with your desktop). that being said... when I put my ear on my G75 bottom I hear only air flow...no humming noise...

edit- Ok I double checked and if I listen very hard on the exaust I guess I can hear a certain pitch to the airflow sound (but it sounds like a normal vent to me- that is vent motor) Hope this helps...

Come to think of it, I can hear the humming occasionally on my G53SX, and it is working fine. It simply the fan motors and moving air. Nothing to worry about so long as it isn't really loud or sounds like something grinding. Moving air generates a tone, which is why lots of musical instruments work. :)

The fans on this lappy really are amazing...my sister has a VAIO, which is about 1 year old, God I hear that thing from different rooms....now my G75, whisper quiet, just the sound of airflow....it only gets noisy when that damn HDD starts spinning :P...

I think that people, who switched from another Notebook to the G75, notice that the fans are quiet! But if you come from a G73, you might notice that the fans make other sounds. And i think that this other "humming" sound, make them seem louder compared to the olter G7X models.
One information: I had a model with that humming. i could reduce the humming of the fan (it was just the one side, the other one was silent!) by flipping the notebook upwards (so that the fan stand 90° to the table). So i sent that notebook back... who knows what happens with that fan in some months. The second one was much better. Still a humming like sound but not that irregular as in the first model.

You have to be lucky to get a good model. I changed my G73 3 times (First with defective fan, did not work. Second had a defective mousepad with non-working button. Third was ok.)
The G75 seems to be the same thing concerning the quality...

Same experiences here. Sounds like it is time for an SSD upgrade! :D

You know you have an awesome computer when you say, "man, my comp just got loud - the HDD started spinning." :cool:

well...the G series is no doubt quieter than other gaming notebook
But compare it to a small laptop for example lets say...macbook air...the fan noise just isn't as quiet in idle...
With G series, I can clearly hear the wind blowing out of the exhaust in very quiet environment, whereas macbook...even when I put down my ears to the keyboard...the noise can hardly be heard...its almost completely silent...

This is just my experience.

I had G73 and it was quiter than G75 but G75 is still better than other gaming laptop.
I had clevo 170EM and I sold out on ebay because the fans was loud like vacum cleaner.
