how to make Z70V more quiet?

After turning on Z70V for about 5 minutes, there's always fan noise not comes from CPU nor HD, I guess it's from graphic module (ATi mobility x600). How can I stop the graphic cooling fan, guys?

I tried to slow down the graphic core & memory speed using CHC, but no help

 

anybody have any clues on this? i got a z70v the other day and found the noise from gpu fan to be really horrible. high-pitched headache inducing whine. i'm surprised only two people have found this to be a problem...

i've tried ati tool, but it has no support for fan control on the x600. also tried underclocking, but like gshgsh said it doesn't help at all.

did gshgsh and i get bad fans, or are our ears too sensitive?

 

do a search, there's been posts on controlling fans speed and reading the temperature. Hint: i made the post.

 

flaxx- read the two posts you were referring two. they appear to be about the z71v, which uses a different graphics card. you know if the same methods work with the ati x600? also, are you actually able to control the fans or just monitor temp? sorry, it wasn't crystal clear in the other threads...

 

ok, did a little more digging, and this post seems to indicate that you can you use speedfan to control the fan on the x600 in a z70v.

to summarize ... you need to run everest (freeware) in order to get speedfdan to read all the fan and temp sensors. then you can use speedfan as normal to control fans (cpu and gpu).

anyone feel like doing a little confirmation? yes or no will do just fine... i jumped the gun and rma'd my notebook so i can't try it out myself. (i think the fan was defective anyway... the high pitched noise sounded like other bad/very-poor-quality fans i have known and hated.)

thanks to flaxx for the info in the all threads regarding this matter.

 

If I were you, I wouldn't mess with the speed of the fans. They switch to high for a reason. I remember on the earlier bios versions that the fans didnt kick on that easily, but after more and more updates, the fans have been kicking on right away. I guess the peeps at ASUS think the fans should kick on earlier. Would you want all that heat to stay trapped inside?

If you think it should be "quieter" then I would just underclock it with Centrino Hardware Control (CHC). http://www.pbus-167.com/chc_main.htm Its amazing, it'll run at a slower speed, generate little heat, and use less of your battery. It'll kick on the max processor speed when needed, such as games or whatever. Leave the fans alone and let them kick on when needed also. There are many threads on CHC, try looking them up.

 

thanks for your input madmike. i've read many of your posts on this forum and at notebookforums, and i definitely respect your input.

chc is a great program and can be used very effectively and safely to reduce heat from the cpu by undervolting, thus reducing the necessity for the cpu fan to run at high speeds (or even at all, for that matter.) i used it for a long time on my old hp zt3000, and it seemed to work equally well on the z70v for the short time that i had it. i actually found that, with chc especially, the cpu fan on the z70v is very quiet. i agree that it is unnecessary and likely undesirable to mess with cpu fan speeds.

the issue here is being able to reduce the speed of the x600 fan when doing only simple tasks like wordprocessing and web browsing. the gpu fan should not need to run at full speed when doing simple 2d acceleration, especially if the gpu is underclocked (less heat). the x600 can be underclocked significantly using chc, yet another great feature.

i would also agree that it probably is unwise to mess with the gpu fan if you are doing heavy 3d acceleration like when you are playing games. but for normal 2d stuff, i think it is probably quite safe to turn that fan down a bit...

 

using everest is to detect the GPU temp (with the 6600 go) -- you may not need this step. However, the steps in controlling the fan are identicle since we have the same north bridge and ACPI BIOS. To control the fan, just read the first post:

ok flaxx, i hear you loud and clear. as far as i am concerned, this matter is resolved. i still wouldn't mind hearing from a z70v owner who has done this successfully, just for that extra little peace-of-mind...

thanks to all who contributed.

 

I own the Z70V and I've done it successfully. There are many others, just have to do a search on Z70V and CHC. You can check out their settings. If you've got it at default settings, it should quiet it way down. There was this one guy who said that it didnt make a difference, but his computer was already at a high temp. It takes awhile to cool down, so you won't see a difference just by running it now while it's been on. When I do a cold boot in the morning, its sometimes at 39c and slowly goes up to the mid 40's- 50.
