Sony Vaio Z fan problem

Hey every, today I got myself a Sony Z16, everything has been good except for the fan being very noisy. Im not sure if this is normal or not maybe some of the people here can share their experience. As soon as I turn the Z16 on the fan starts to spin even if the cpu etc isnt even hot. Just this idle spinning speed is already annoyingly noisy to me. Compare to my TZ26 the fan does not spin unless the cpu gets very hot then it starts spinning very loud. Do all the Z series laptop fan start to spin as soon as they are turned on? Also it gets even louder if the laptop gets hot...

Is there anyway of fixing this? Thanks

 

Put Vista in energy saving mode AND select the silent mode in Vaio control center.

Besides that, anything that will limit the CPU load can reduce fan activity. For example: a clean install, disabling services, disabling flash.

And yes, complaints about fan noise on the Z are normal.

 

Hey, thanks for the tip, it did help when i turn it to silence, however its still noticable, is there no way of stoping the fan? At idle cpu only 33degrees doesnt even need the fan running, or is this only possible in future time when Sony updates their bios?

I am on a clean install and have turned everything off possible at start up.
Is there anything further I could potentially do or this is near limit as this time until Sony does something with the fan speeds?

Really my impression on the Z series is 99% perfect except this 1% of annoying fan noise. Hopefully something comes up for fix soon.

Thanks

 

try undervolting your cpu, do a search on these forums and you should be able to find some threads regarding this topic. as far as i've recall, it was effective in reducing fan noise.

 

Would that void warrnty? But I thought the problem was not just how fast it spins, instead its that it spins when it doesnt need to(i,e at idle whole thing aint even hot it just spins for fun). Wouldnt this be a fan program problem how the Z series have been set. But anyway thanks for the idea, I will read stuff on under volting and give it a try see how it goes.

Everyones help is appreicated

 

No, undervolting the cpu won't void the warranty, it makes the laptop run cooler, which might quiets the fan down a little bit..

 

I don't quite figure how if the temp is 33°C when the fan is running, it automatically means that the fan doesn't need to run. If the heat emitted by the CPU isn't vented, the temperature will rise until the fan will just have to come on eventually anyway. It might be that the on-off whir of the fan ends up more annoying than a constant quiet level?

I use undervolting on my Z and it makes a massive difference to fan noise when at full load, but doesn't make any difference to the idle fan noise IMHO. This is presumably because you can't lower the voltage for the minimum clock multiplier.
The good news is that it won't void your warranty and it's totally safe (and temporary - if you get any problems, just reboot without RMclock running and it you'll be back to stock settings). I haven't had any problems with my Z since undervolting and I've done many hours of video encoding (100% CPU) since applying the settings.

 

33c in idle? Is this normal? I thought it would be higher than that.

 

In other words, it is still the case that with the Sony Vaio Z Notebook the FAN is ALWAYS running even if in idle and using the integrated video adapter?

 

if the fan is noisy it needs to be replaced. Usually the fans that come with the system are very cheap and loud.

 

No, as far as I know, in idle it comes on about 40-50% of the time.

Or the lowest setting was completely inaudible to me.

Who knows, Sony may update the BIOS. Maybe they choose the slightly more aggressive fan setting because of all the Nvidia comotion.

Or think of it in a different way, now your laptop will stay extra cool

 

One question, does undervolting cause a decrease in CPU performance?

 

No it does not.

 

1 question
is yours made in japan or america?

 

You mean the one I owned? It was preconfigured model so I guess Japan. Haven't really checked.

But I don't think it matters for the fan issue.

 

can someone please explain to me why undervolting does not decrease performance?

 

Because the processor speed stays the same, you are just provideing it with less power.

 

The fan is pretty much inaudible after undervolting it, I've discovered. Though if you put your ear right next to the fan, you'll still hear something. From what I've found, if it's on your lap, you won't be able to hear anything. If it's on the desk, you can slightly hear a fan noise if you concentrate enough. This on idle/web browsing and other tasks without heavy cpu dependence.

 

i don't get it, then why aren't all laptops undervolted? there has to be a downside somewhere... right?

EDIT: nevermind, i just found the undervolting guide under the hardware section, very interesting!

 

thanks for the info, i'll try to undervolt mine

I am following this guide and ran Orthos CPU loader to get maximum temps but I had to shut it off after 3.30 minutes.

I got a max temp for core0 of 83C and core1 86C.

2 mins later the temps are back to a more 'normal' rate 48C for both cores. (pretty fast cooling in two mins).


Don't they seem a little high? What values did you guys get?
And what did you undervolt to?

 

I undervolted my p9600 and now after 3.30mins i get a max temp for core0 of 71C and core1 74C.

That's 12C less. I am impressed....
